<br />
Abstract - Next Generation suit designs, taking lessons from current analogue suit designs.<br />
Paul Graham, OpenLuna Foundation<br />
London, Ontario, Canada <br />
<br />
<br />
With the resurgence in interest and activity to return to the moon and Mars, significant thought must be<br />
given to Space Suit, Lunar Surface Suit (LSS), or Mars Surface Suit (MSS) designs. Factors that need<br />
to be considered include physical, data, and human factors issues. Specifics include items as mission<br />
duration requirements, availability of consumables replenishment, power utilization, waste<br />
management, communications, data management, entertainment and other user needs. Since the<br />
physical requirements are defined by the mission profile, they will be considered as baseline<br />
requirements. Also some data and human factors needs will also be considered as baseline<br />
requirements, others are more flexible, and should be driven by the individual mission and operators<br />
needs. These needs would best be defined through extensive analogue testing in a relevant environment<br />
performing realistic and relevant tasks. Therefore, this author believes that analogue suits should be<br />
designed as close as practicable to their real counterparts, and real suits should be designed from the<br />
lessons learned in the use and testing of their analogues. From 2001 to 2008, the author has been overseeing<br />
operations at the Mars Desert Research Station (MDRS) and Flashline Mars Arctic Research Station<br />
(FMARS), Observing simulations using primitive analogue suits, and gathering data on suit<br />
functionality from the perspective of the experienced field scientists and engineers who use them. Also,<br />
the author has been working directly with the OpenLuna suit development team in the design of their<br />
LSS. Using the process described above, OpenLuna will be developing a LSS that will meet or exceed<br />
their own, and NASA requirements. Beyond the minimum physical requirements, such as a 120 hour<br />
continuous pressurized time for NASA's Constellation needs for their Lunar Design Reference Mission<br />
(LDRM), close examination of existing analogue usage suggests that the following features should also<br />
be included in both analogue and space-worthy suits; an internally available food supply, drinking<br />
water supply, carbon dioxide, liquid and solid waste disposal, in-suit communications and navigation<br />
with redundant systems, temperature control, remote medical access, long duration radiation shielding,<br />
personal in-situ resource utilization, environmental protection, mobile power sources, and resource<br />
recycling. Rescue and recovery of an injured explorer or a damaged suit should be considered. Along<br />
with these basic physical needs, other features should be included such as enhancements in assistance<br />
for scientific studies, in-suit documentation, recording, and location capabilities. Available to the<br />
wearer should be local copies of engineering or scientific documentation, mapping and other data<br />
resources. Entertainment should be considered to help maintain morale during long transits, tedious<br />
tasks, or during emergencies. Lastly, the suit must be modular, inexpensively manufactured, easy to<br />
maintain and clean, durable enough to provide physical protection and must be able to operate in a<br />
wide variety of environments, with variable outerwear for special needs. All of the features should be<br />
extensively tested in an analogue environment before introduction into space-worthy suits, and any<br />
changes in the real suit needs should be reflected in their analogue counterparts.<br />

Two WEEKS in a suit?! Why?????<br />
Pardon my outburst. . .I meant no disrespect.<br />
I have been working on this issue for awhile and am currently pursuing this approach: It's called the 50/50 design. The spacesuit begins with a pressure/thermal protection garment with an oxygen breathing system, small heat rejection module and CO2 scrub unit. Very basic. This unit is worn during launch from Earth, all maneuvers in space and the lunar landing. Maximum capability for each O2 fill is only two to four hours, depending on level of activity. <br />
<br />
On the Moon - before doing anything else - the astronaut must access a pre-landed logistics module and add several elements to the basic suit. These include larger life-support module able to sustain ten hours of activity per charge, a hard, one-piece upper 'carapace' that has computer, with head-up display, communications and even external lights. This unit is bulky, relatively heavy and completely out of the question for use during lunar flight; it stays on the Moon and is used over several missions.<br />
<br />
A second unit attached to the right hip section is a thermal management system about the size of a loaf of bread but conforms to the shape of the hip. It cycles a 60/40 water/glycol mix through a series of bladders capturing the astronaut's excess body heat. <br />
<br />
A third unit on the left hip is the waste management system. You can probably guess how that works. In the front, between the two sections just described, is a tool box. <br />
<br />
When this unit is attached, the astronaut switches to an oxygen/nitrogen mix that is lower than terrestrial pressure with a higher O2 percentage.<br />
<br />
During flights, if there is a problem with the cabin pressurization, the astronaut simply umbilicals directly to the spacecraft O2 supply, bypassing the cabin distribution system.<br />
<br />
______<br />
<br />
In response to "Two WEEKS in a suit?!"<br />
<br />
Well, We we trying to save weight every way possible, and having a shelter or capsule just add weight, and bring little more than comfort to the operation. So, we are going to drop the comfort to save cost. Your design, although very well thought out, wouldn't work real well for us, for one thing, we won't need a cooling garment, we're currently focusing on MCP, (although we are considering something along the lines of the NDX-2) and, since we are running without a capsule, we will be flying in the MCP/HUT hybrid system. Also, something I discovered during my many thousands of hours SCUBA diving, the worst part of diving is putting the wet suit ''back on''. I'd rather just get used to the wet nasty suit, and keep wearing it, rather than get in and out of it. We will bring a light, inflatable "tent" for emergency cleanups or getting a nasty wrinkle out, but it is not intended to be used continuously.<br />
<br />
I will post more about my current thinking on suit design ofter the paper is presented at IAC.<br />
<br />
Never forget though, this is an open project, and I could be wrong. We will never take a "That's just the way it is, deal with it!" stance when there are facts to point in the other direction, we are entirely fact and demonstration driven. I'm building an analogue suit just to test all of the concepts for the suit, and intend to actually spend three weeks in the suit, eating, sleeping, and all else that would be expected. (Yes, Waste management is my biggest concern.) You are welcome, no '''''invited''''', to do the same. If your design is superior, it '''''will''''' be the one that flies...<br />

''"The Moon Shines on all the Earth..."''<br />
<br />
The Open Luna Foundation aims to return mankind to the moon through private enterprise. Initial goals focus on a stepped program of robotic missions coupled with extensive public relations and outreach. Following these purely robotic missions, a short series of [[crewed missions]] will construct a small, approximately 6 - 10 person [[outpost]] based on a location scouted by the robotic missions. This [[outpost]] will be open for anyone's use (private individuals to government agencies), provided they respect our [[ethical conduct]] and [[cultural heritage]] policies.<br />

== Proposal to Modify the OpenLuna Wiki ==<br />
<br />
For the proposal, please follow this link: [[Proposal to Modify the Wiki]].<br />
<br />
This is a proposal to completely reorganize the wiki for better access and navigation. Several suggestions are made including the use of portals for different functional area, how to design tasks and how to organize the OpenLuna members. All members are encouraged to read this proposal and discuss its benefits and weaknesses in the discussion page. Also, feel free to correct any wrong or misleading information under 'Functional Areas and Wiki Portals'. Coordination in migrating all pages to new portals is essential in order to maintain a smooth use of this site and avoid any loss or duplications of pages.<br />

<br />
Editor/contributors should also be sure to 'Watch' your pages, to see if anyone responds, enhances, or detracts from your valuable contributions.<br />
<br />
== References ==<br />
<br />
It is important for an open project to have open sources. Published books are good, Open source, or creative commons publications are better. For example, there are tons of open NASA reports.

<hr />
<div>The first part of constructing the surface suit will be development through [[analogue_surface_suit | analogue]] testing in relevant environments.<br />
<br />
We are making our decisions based on certain [[Suit_design_concerns|design concerns]]<br />
<br />
We are working under the thought that the suit needs to be as light as possible, but be completely self-sufficient. Consumables will need to be swappable while wearing the suit. (Remember, the first four will spend two to four weeks in it, and the follow on missions may need to spend 3-4 days in them.) We do not intend to significantly change the suits unless a dramatic change is made to the state of the art.<br />
<br />
This suit is expected be of a [http://en.wikipedia.org/wiki/Space_activity_suit MCP]/[[HUT|HUT]] hybrid; although a HUT/soft suit in the style of the University of North Dakota NDX-2 is also being considered. The wearer will wear a coverall over the suit body for armour, heating, or dust mitigation. in future versions, these coveralls will be interchangeable. The helmet will be fixed to the HUT, with several flat planes for view plates. The rational behind flat plates is in ease of spares storage, ease of repair, and ease of polishing/maintenance. The [[PLSS|PLSS]](Portable Life Support System), [[HUT|HUT]], and [[Helmet|helmet]] will also be integrated. The HUT will be entered from the front. Since the view plate is not hemispherical, the view plates will contain electronically polarizing elements for sun mitigation. There will be two water delivery nipples as described elsewhere, as well as two food delivery nipples, one for a savory food, one for a sweet food. Local communications will be handled via a routable VoIP protocol over a WiFi variant, via a computer as described above. This is basically an always on system that would be the equivalent of talking to the people in your immediate area. This entire system will contain redundancies. Long distance communication could be over amateur radio. The suit will be constructed from firm elastic cloth and laced to tension using a speed lace style system. The helmet will also have redundant [[Helmet_Lights|lights]] and [[Helmet_Cameras|cameras]].<br />
<br />
<br />
[[Suit_Boots|Boots]] are expected to be near off the shelf Canadian Pack Boots. [[Suit_Gloves|Gloves]] should be modeled as close as posslble to suit gloves, and made in the same lace-up MCP style as the suit pressure layer. There is a spiked traction system being developed by [[Kepler_Shipyards|Kepler Shipyards]] that will be integrated into the boots.<br />
<br />
As much expired water as required will be condensed out and recycled. Sweat is vented to cooling. For missions longer than a day, or for experienced operators, urine may be collected from either a catheter or a surgically installed stint and extraction port. Feces will be collected via a user installed anal catheter. Both medical devices are being developed by Kepler Shipyards.<br />

== Artists Notes ==<br />
<br />
The suit described above will be skin tight with laced seams on the sides. there will be small metal or plastic clips on the lace points. The color should be pleasing. the laces will be stainless or spectra. The HUT will basically cover the ribcage, like a short vest. The helmet is attached to the top, the PLSS and helmet are integral. The PLSS will extend down halfway to the waist and will be about 40 cm thick, as wide as the back, and up to the top of the shoulders. There will be a heavy solid connection between the back of the helmet and the PLSS. Note the faceplate panes from above.<br />
The armour coveralls will be looser, but not very over the suit, and will have several straps and clips to keep the knee, elbow, shin, forearm and thigh pads in place. The colour will be a combination of lime Hi-Vis green and some other artistic, attractive design. <br />
<br />
Think a combination of "Red Planet" surface suits for the body, Cary-Ann Moss's helmet (but flat planes, not curved.) and the color and style of "Iron Man".<br />

<hr />
<div>'''List of automation needed for a container held aquaponics system:'''<br />
<br />
All readings, data logging, and switching ON/OFF must be available for review/control via a webpage browser, with logging.<br />
<br />
Some ideas how it looks like are visible here:<br />
<br />
1) This senior citizen runs aquaponics with automation... http://youtu.be/X2wWTadsBDA<br />
<br />
2) And younger man, self-made automation: https://www.youtube.com/watch?v=nx-qK7BdZjc<br />
<br />
<br />
For each Aquaponics System:<br />
<br />
1. pH meter in the water.<br />
<br />
2. DO /Dissolved oxygen/ meter (in the fish tank) - low reading means something is rotting - dead fish, plant or similar. (and will raise the stink, and kill other stuff in the tank.)<br />
<br />
3. Temperature - of the air and of the water in each of the tanks. (This will help track the biological processes.)<br />
<br />
4. Time for each cycle in each Grow Bed. (How would we measure this? PGG)<br />
<br />
5. Is the water pump running - reading to the voltage and amperage of the pump(s).<br />
<br />
6. Speed of the water /if the water is moving, then pump is running and nothing is clogged.<br />
<br />
7. Speed in the air /the air fans are running, and everything above said for the water pump - voltage and amperage readings for air fans.<br />
<br />
8. light availability for plants (For natural lighting and to determine if the grow lights are operating correctly.)<br />
<br />
9. Optical detection in the air conduits between modules to check for bee or other activity.<br />
<br />
10. CO2 levels in air and water.<br />
<br />

The suit described above will be skin tight with laced seams on the sides. there will be small metal or plastic clips on the lace points. The color should be pleasing. the laces will be stainless or spectra. The HUT will basically cover the ribcage, like a short vest. The helmet is attached to the top, the PLSS and helmet are integral. The PLSS will extend down halfway to the waist and will be about 2 cm thick, as wide as the back, and up to the top of the shoulders. There will be a heavy solid connection between the back of the helmet and the PLSS. Note the faceplate panes from above.<br />
The armour coveralls will be looser, but not very over the suit, and will have several straps and clips to keep the knee, elbow, shin, forearm and thigh pads in place. The colour will be a combination of lime Hi-Vis green and some other artistic, attractive design. <br />

<div>Aquaponics, for those who don't know, is a blend of Hydroponics and fish farming.<br />
[[File:Aquaculture1.png]]<br />
<br />
OpenLuna plans on using several aquaponics modules for O2/CO2 management, food production, water purification, waste management, and simply for entertainment and other human factors. <br />
[[File:Aquaculture_lounge.png]]<br />
<br />
There will be several units installed as part of the outpost. eventually, there will be enough to completely support the facility, and a limited number of visitors. <br />
<br />
Some of the modules will be partially exposed on the surface, with a thick water jacket as radiation shielding, and to sanitize the water. <br />
<br />
The plants will consist of food plants (for the people and the fish), herbs, water purification plants, (Water hyacinth for example), air purification (O2/CO2 exchange), and smell improvement (mostly attractive flowering plants near the lounges), (The stinkier anaerobic process will be kept out of the crew breathable air.), and bamboos for some structures. There will several hydroponic and airponic flowering and edible herb walls near various lounges and near the kitchen, but these are not considered part of the aquaponics systems.<br />
<br />
Fish will be used for crew protein supplement.<br />
<br />
There will be honey bees inside these modules to provide sweeteners to the crew, but most importantly, to provide pollination.<br />

<div>Hard Upper Torso<br />
<br />

<br />
'''From Wikipedia, the free encyclopedia'''<br />
<br />
[[File:HUT_NASA.jpg|link=http://upload.wikimedia.org/wikipedia/en/8/87/HUT_NASA.jpg|200px|left]]<br />
A Hard Upper Torso Assembly, or HUT, is a central component of several space suits, notably Roscosmos' Orlan and NASA's Extravehicular Mobility Unit (EMU). The fiberglass HUT forms a rigid enclosure about the upper body of the occupant, providing pressure containment for this part of the body. The HUT incorporates structural attachment points for the arms, Lower Torso Assembly (LTA), helmet, chest-mounted Display and Controls Module (DCM), and Primary Life Support Subsystem (PLSS) backpack.<br />
<br />
The original HUT design for the EMU, first used in 1980, included bellowed shoulder bearings, which allowed for variation in the angle of the shoulder bearings. This allowed for one configuration to ease donning of the suit, and a different configuration to allow maximum mobility during EVA. However, the limited life of the bellows prompted a redesign in 1990 to a fixed shoulder bearing angle and position, referred to as the Planar HUT, resulting in reduced mobility and more difficult donning and doffing.<br />
<br />
Because of the high cost of manufacturing, only three sizes of HUTs are produced for the EMU. This has the effect of limiting the number of people who can be properly fit for the suit. The three HUT sizes are supposed to accommodate occupants from the 5th to the 95th percentile.<br />
<br />
The HUT also includes an In-Suit Drink Bag, with a plastic tube extending into the helmet, to allow the astronaut to stay hydrated.<br />
<br />
'''--The OpenLuna HUT --'''<br />
<br />
The current plan for the OpenLuna HUT is that it will contain the counter-lungs, (allowing the system to operate more independently of the air purification system) several [[Medical_Considerations|medical devices]], and will provide a connecting point for the lacing system. It is currently being developed as a front entry and bottom entry device, rather like a SCUBA tank. It will contain an integrated helmet for C-Spine protection, with a removable front mask. As such, this wiki page contains the jumping off point for the [[suit_helmet|helmet]]. The [[PLSS|PLSS]] will hang from the back, and will attach to the suit by concealed hoses that will allow the operator to remove it without depressurizing the suit, and will allow extension hoses and external tethering and buddy breathing.<br />
<br />
---Manufacturing<br />
<br />
Current plans call for each suit to be custom made for specific suit operator (or just Operator) using 3D body scanning, then a vacuum forming mold will be made from the scan (allowing room for the counter-lungs and other medical devices, and allowing some room for body size change from reduces gravity or - other considerations) and the HUT will be "Vac-formed" out of HDPE (High Density Poly-Ethylene) for it's radiation shielding properties.</div>Paulhttp://openluna.org/wiki/index.php?title=Medical_ConsiderationsMedical Considerations2013-04-10T16:34:34Z<p>Paul: </p>

<br />
Please do all discussion, and look for working ideas in the discussion page.<br />
<br />
One good thing is that maybe an exposure to vacuum will kill germs hiding in the suits.<br />
<br />
My proposed [[Lunar lodge]] uses the airlock for storage of suits which will be exposed to vacuum evry time the lock is cycled.<br />

<hr />
<div>'''This Page is for the wild ideas we all have.''' <br />
<br />
'''======================================================'''<br />
<br />
* Would it be possible to replace the laces with a "memory" type plastic that <br />
could be heated and stretched to put the suit on and when the heat is removed it would <br />
contract to pull the suit tight.<br />
<br />
* Lacing the arms would be extremely difficult to do by yourself. Use hook & loop or possibly zippers. Needs to be done one handed.<br />
<br />
* Break the lacing at the hip. Have the top lace down and the bottom lace up. Easier to do by yourself and can be done standing up.<br />
<br />
* Helmet Inlet and exhaust air hole needs to be about 40mm surface area, with reliable one way valves. (pgg - Discussion with Narked@90) - any variation on that theme will work. The current design we worked out involves the breathing gas return from the rear base of the helmet, the inlet air as two slits with their supply hoses tapering in from both sides, blowing onto the faceplates.<br />
<br />
* How about a small sample lock so the operator can sample rocks from outside.<br />
<br />
* The suit helmet needs a vomit outlet port. Perhaps through the sample lock?</div>Paulhttp://openluna.org/wiki/index.php?title=Marketing_projectsMarketing projects2013-03-08T17:55:48Z<p>Paul: quick start</p>

<br />
For more general discussion or question asking, look in the discussion page first. You should also read all of the existing pages before starting any new ones. (Start with '''[[Mission_Plan]]''') You should also look in the discussion pages before editing anything. (Edit with care. Read the '''[[Equipment design standards]]''', [[editing protocols]], the discussion pages for your topic and the [[Mission_Plan]] before editing anything.)<br />
<br />
You should also note that we are breaking out some '''[[individual components]]''' here.<br />
<br />
We are starting to break out a series of '''[[projects]]''' here. This is a quick list if you are looking for any kind of project ranging from simple weekend hobby projects, to senior design projects, to major development and construction projects. These are [[hardware_projects|hardware]], [[scientific_projects|scientific]], and even [[marketing_projects|marketing and PR projects]].<br />

== About the Google Lunar X-Prize ==<br />
<br />
First note that we are not now, and do not ever plan on becoming a Google Lunar X-Prize team, even though we work with one. (and are open to working with others.) Having said that, The Google Lunar X PRIZE is a $30 million international competition to safely land a robot on the surface of the Moon, travel 500 meters over the lunar surface, and send images and data back to the Earth. Teams must be at least 90% privately funded and must be registered to compete by December 31, 2010. The first team to land on the Moon and complete the mission objectives will be awarded $20 million; the full first prize is available until December 31, 2012. After that date, the first prize will drop to $15 million. The second team to do so will be awarded $5 million. Another $5 million will awarded in bonus prizes. The final deadline for winning the prize is December 31, 2014. More can be found at [http://www.googlelunarxprize.org GLXP website]. In case they change the rules, see our plan to win as [[Mission_X]] But also see [[GLXP]] as to why we will not enter unless they do so.<br />

== Proposal to Modify the OpenLuna Wiki ==<br />
<br />
For the proposal, please follow this link: [[Proposal to Modify the Wiki]].<br />
<br />
This is a proposal to completely reorganize the wiki for better access and navigation. Several suggestions are made including the use of portals for different functional area, how to design tasks and how to organize the OpenLuna members. All members are encouraged to read this proposal and discuss its benefits and weaknesses in the discussion page. Also, feel free to correct any wrong or misleading information under 'Functional Areas and Wiki Portals'. Coordination in migrating all pages to new portals is essential in order to maintain a smooth use of this site and avoid any loss or duplications of pages.<br />

<hr />
<div>The first part of constructing the surface suit will be development through [[analogue_surface_suit | analogue]] testing in relevant environments.<br />
<br />
We are making our decisions based on certain [[Suit_design_concerns|design concerns]]<br />
<br />
We are working under the thought that the suit needs to be as light as possible, but be completely self-sufficient. Consumables will need to be swappable while wearing the suit. (Remember, the first four will spend two weeks in it, and the follow on missions may need to spend 3-4 days in them.) We do not intend to significantly change the suits unless a dramatic change is made to the state of the art.<br />
<br />
This suit is expected be of a [http://en.wikipedia.org/wiki/Space_activity_suit MCP]/HUT hybrid; although a HUT/soft suit in the style of the University of North Dakota NDX-2 is also being considered. The wearer will wear a coverall over the suit body for armour, heating, or dust mitigation. in future versions, these coveralls will be interchangeable. The helmet will be fixed to the HUT, with several flat planes for view plates. The rational behind flat plates is in ease of spares storage, ease of repair, and ease of polishing/maintenance. The [[PLSS|PLSS]](Portable Life Support System), [[HUT|HUT]], and [[Helmet|helmet]] will also be integrated. The HUT will be entered from the front. Since the view plate is not hemispherical, the view plates will contain electronically polarizing elements for sun mitigation. There will be two water delivery nipples as described elsewhere, as well as two food delivery nipples, one for a savory food, one for a sweet food. Local communications will be handled via a routable VoIP protocol over WiFi, via a computer as described above. This entire system will be redundant. Long distance communication could be over amateur radio. The suit will be constructed from firm elastic cloth and laced to tension using a speed lace. The helmet will also have redundant [[Helmet_Lights|lights]] and [[Helmet_Cameras|cameras]].<br />
<br />
[[Suit_Boots|Boots]] are expected to be near off the shelf Canadian Pack Boots. [[Suit_Gloves|Gloves]] should be modeled as close as posslble to suit gloves, and made in the same lace-up MCP style as the suit pressure layer.<br />
<br />
[[Image:Surface_suit-Pressure_liner.jpg|thumb|400px| Suit MCP pressure liner]]<br />
[[Image:Complete suit.jpg|thumb|400px| complete suit]]<br />
<br />
<br />
<br />
<br />
<br />
== Artists Notes ==<br />
<br />
The suit described above will be skin tight with laced seams on the sides. there will be small metal or plastic clips on the lace points. The color should be pleasing. the laces will be stainless or spectra. The HUT will basically cover the ribcage, like a short vest. The helmet is attached to the top, the PLSS and helmet are integral. The PLSS will extend down halfway to the waist and will be about 2 cm thick, as wide as the back, and up to the top of the shoulders. There will be a heavy solid connection between the back of the helmet and the PLSS. Note the faceplate panes from above.<br />
The armour coveralls will be looser, but not very over the suit, and will have several straps and clips to keep the knee, elbow, shin, forearm and thigh pads in place. The colour will be a combination of lime Hi-Vis green and some other artistic, attractive design. <br />
<br />
Think a combination of "Red Planet" surface suits for the body, Cary-Ann Moss's helmet (but flat planes, not curved.) and the color and style of "Iron Man".<br />
<br />
[Could I order one of those cod-pieces somewhere? 8-] [[User:Navigaiter|Navigaiter]]<br />

They come stock with the pressure liner. (Both the hard shell one, and the "Modesty cover")<br />

==An idea to reduce the volume of the payload==<br />
<br />
By: [[User:Len|Len]]<br />
<br />
By filling the inflatable items on the mission with expanding foam (it comes in various densities) things such as the sleeping cubes, the tables and chairs, and room dividers are all items that can be collapsed to a fraction of the volume of standard items. Since the expanding foam generates CO2 it will self inflate the object. <br />
<br />
The foam comes in several different densities - ranging from styrofoam to rock. Filling inflatables with foam will have the benefit of adding rigidity to the item. <br />
<br />
This assumes that the foam will expand normally in a vacuum at lunar gravity levels and it should be noted that the foam is temperature sensitive during expansion - extensive testing would be required.<br />
<br />
This is another off of the shelf solution available to the mission.<br />
<br />
== A new request==<br />
<br />
<br />
[[User:Paul|Paul]] 05:17, 12 December 2009 (UTC) - I would like to see a floor plan that is sausage shaped, all inflatable, and designed for microgravity use. It would only need two locks, (They may need to be something that can dock to an ISS standard dock.) and a small suit prep room. It would be used for space travel, sort of like a cheap ship for a Near Earth Object (NEO) mission. (Call it 120 days habitation for four people.) with two weeks on the "surface" where it may be tethered (or at least in orbit around).<br />
<br />
When we are done with it, we could use it as a ship to transfer from Earth to Luna for the tourists. (Kind of like a powered cycler.)<br />
<br />
[User:Len|Len]] 10:06 February 10, 2010 - If the Inflatable were to be filled with expanding foam the overall strength would improve as would the ability to repair hull breaches without the worry of the hull collapsing. On the flip side, hull fabric would be more susceptible to <br />
penetration by hard or sharp edges it would not flex (in the event of accidental contact) as would a gas filled hull.<br />
<br />
<br />
== A couple possible floor plan options. == <br />

[[Image:COLORIZED_FLR_PLAN.jpg|thumb|900px|An alternate floor plan. From [[user:Len|Len]]]]<br />

[[User:Navigaiter|Navigaiter]]<br />
I love Quonsets! There's a reason they were shipped all over the world for wartime spaces. That's why I wonder what is the rationale for the "inflatable" hab idea? Besides light weight, I mean.<br />
<br />
Note that the airlock between rooms can and perhaps should be just an airtight door since it is a redundant airlock and ther'll never be vacuum on one side of it since it isn't an exit door.<br />
<br />
- Well - It's possible to have a vacuum in the Dirty Lab, if they needed to have the lock completely open to get something big in it, (Like a stretcher or a bad piece of larger hardware for repair.) or shovelling a bunch of material in or out. Also, We really wanted a small room to be sealed for a last vacuum cleaning (dust removal) before entering the living quarters.<br />

Size and weight. The Quonsets shape is being considered because of the strength to height ratio. Please look around and make more suggestions or help us detail this. We are wanting to move to a first stage analogue soon. [[User:Paul|Paul]] 01:09, 26 June 2009 (UTC)<br />
<br />
Lighter simpler and easier. Granted in spades. Yeah but... I'm starting to worry about the response of an inflatable structure to having tons of regolith dumped on it. ?? [3-meter cosmic shielding] <br />
<br />
I kinda like the alternate idea of bolting two Quonset Huts bottom-to-bottom to make one cylinder. ?? Darn. I'm sorry. But. A buried hab will flex, won't it, when pressure variations and temperature fluctuations occur? Seems like this'll stress a fabric hab skin faster than an aluminum alloy Quonset.<br />

---<br />
<br />
----<br />
[[User:Navigaiter|Navigaiter]] Anyway -- to discuss my revisions to the outpost drawing by Len, which I fundamentally change his multi-room outpost idea into a tiny first-habitation [[lunar lodge]] (discussion branches off here) type of structure. They are just beginnings, please discuss and revise them.<br />
<br />
The hab is inflatable. Much as I love Quonsets, they require a big heavy rigid floor because their internal pressure will try to blow the panel arches upward from the edges of the floor. This force also requires an unbendable floor and strong angle beams along the baseplate joining arches to floor. After the LunaCrete Factory is up and running and pouring slabs for Quonset huts, they will become the hab of choice.<br />
The hab endcaps are round for the same reason as the "floor" is round; joing a flat surface to a round surface creates a corner with huge bending force, ie, structural failure points which require strong angle beam reinforcement with a lot of joiner bolts. Can't afford the assembly time and can't risk the pressure leakage which WILL happen after the structure comes alive and flexes with pressure and temperature changes.<br />
And, of coarse, end caps are round because the hab has to be inflatable and you can't make a balloon with corners ;-]<br />
The hab has just one airlock. If the airlock doors fail, the crew must seek refuge in their Suits and/or in their Lander, mission will be compromised. Sorry. Airlocks are too big and heavy to afford redundancy. LunaDust is highly abrasive and hates hinges, these things MUST be perfectly sealed or the airlocks are soon doomed. So, the one airlock must be large enough for the five[?] crew to pile when the hab looses pressure. Being buried under tons of regolith is scary.<br />
<br />
If there's anything almost as good as exploring Luna, it's talking about it. [:-) Speak up. [Allen Meece]<br />
<br />
[[user:snyder|snyder]]] I'm not quite convinced. Airlocks can be built for different uses. An emergency airlock can have a pretty simple door mechanism and austere furnishings. Think about how a dry bag seals against water. (multiple folds and finally a clip to hold it shut) I don't think this is the design you want for daily use, but occasional would be fine. Also the bigger an airlock is, then the more gasses you will need to pump out for depressurisation. Since you never get it all, you will also lose more when you finally open the door. (look at the Space shuttle's N2 use for EVAs) <br />
<br />
----<br />
[[user:Len|Len]]<br />
One airlock presents a set of problems, first and foremost is saftey. One way in and one way out could be very problematic. Second is dust mitigation, with the dust as fine and as abrasive as I have been led to believe, one set of filters and one vacuum draw down does not seem to be enough to minimize the appearance of dust in the living/work areas. One airlock also does not provide for easy expansion. The 3 airlock design would include a drawn down system for each with a centralized piping system that would allow each pump to be ganged with the others. This of course would provide redundancy and improve the draw down wait time by using all three pumps at once.<br />
----<br />
Hi Len, nice to meet you here in the hab shop!<br />
<br />
----<br />
Safety... One door is simpler than three and simpler is automatically safer. Less to ship, assemble and maintain, less to go wrong. If the hab loses pressure, the one airlock must be big enough to hold all five crew. That airlock has to be robust with dust-proof hinges and latches like on a submarine. Consider the submarine. They don't have extra doors because they don't allow bad doors since that could kill everyone on board. Doors can be made perfectly. The technology is perfected. <br />
Certain parts of any space project are Level One Importance, things which cannot be permitted to be chancey, things like wings on the shuttle, or its windshield, or its solid rockets, say. A single door on the hab would have to be the same priority. If the door fails, like the shuttle solids failed, people may die. Perfection isn't perfect and we have to live with that. [pun]<br />
[[User:Navigaiter|Navigaiter]] 18:59, 4 July 2009 (UTC)Two things that could prevent access to the front foyer, a fire in that end of the hab and a roof blowout/cave-in. Keeping the doorlock area clear of everything, not just flammables, is job one.<br />
Since air pressure is all that's holding up the ceiling, a blowout would drop the roof on the entire hab. Game over. [[User:Navigaiter|Navigaiter]]<br />
<br />
== [[RegoDust]] Control. ==<br />
[[User:Navigaiter|Navigaiter]]This topic moved to its own new page to reduce clutter here.<br />
<br />
== Standard Module Construction ==<br />
<br />
[[Image:Standard Module.jpg|thumb|900px|A proposal for the use of std construction modules [[user:Len|Len]].]]<br />
<br />
[[user:Len|Len]]: Using standard construction modules would cut down on design and manufacturing costs and provide the flexibility to rearrange the Outpost layout according to the terrain.<br />
<br />
[[User:Navigaiter|Navigaiter]]: This is brilliant. All doors and door frames are standardized for the same reason.<br />
<br />
[[User:Len|Len]]: The more we can standardize (and off the shelf '''rocks''') the lower the mission costs will be.<br />
<br />
== Force loads ==<br />
[[user:snyder|snyder]]] I think all Habs are 'inflatable' in a sense. Even an ISS module expands a little when pressurized. Think about using spheres and cylinders because of hoop stress. Internal fittings can make flat floors much easier than making a flat pressure vessile. The loads are really large. consider between 3 and 15 pounds of force for EVERY square inch.<br />
As for the loading of soil from above, lets see .... call regolith density say 0.20 lbs / cubic inch (I dunno, steel is about 0.35), and lunar gravity is 1/6 gee. so 5 feet of regolith on top of a hab weighs about 1 lb. <br />
not much compared with the internal pressure pushing out.<br />
<br />
OK, thanks for the numbers. But the regolith cover is >3 meters thick, or 9' or nearly twice that weight or two 2 lbs per square inch on the top curve. Not a lot but it should pack down with hab vibes and put wear on the inflatable fabric. A show stopper for inflatables or just something to think about when considering the habskin? Stress lines and stretch marks?. [[User:Navigaiter|Navigaiter]]<br />
<br />
<br />
<br />
<br />
== Dust Reduction Possibility ??? ==<br />
[[image:Dust Reduction Layout.jpg|thumb|900px|A proposal for the reduction of dust. The style of the living/work area is arbitrary and shown only for reference.[[user:Len|Len]].]]<br />
[[User:Len|Len]] 04:28, 1 July 2009 (UTC) Assuming that there is a charge inherent to fine grain surface regolith, would it be possible to use a foil lined decent tube to attract it by placing a reverse charge on the foil. After exiting the tube the charge could be reversed repelling the regolith from the foil and allowing it to fall into a collection pit.<br />
<br />
[[User:Navigaiter|Navigaiter]] 18:59, 4 July 2009 (UTC) It may be that the de-duster has to touch the dust to ground it out, de-ionize it, and that means the tube would need to be chock full of bristles. ?? If so, since LunarGrav is only one eigth that of earth, the Mooney can't fall hard and could just drop down, pull himself down, through a tube of bristles. And maybe include a gas blower, CO2 perhaps.[[User:Navigaiter|Navigaiter]]<br />

<br />
== Using the suit room as a "[[dirty lab]]" == <br />
for studying lunar regolith and rocks'''<br />
:<br />
[--[[User:Navigaiter|Navigaiter]] 18:59, 4 July 2009 (UTC)This idea is for the two-roomed hab version. I moved this paragraph down from the headline top of the page because habitation images make the top look better and because this idea of a big dirty lab is less appropriate than using a fume hood in a clean hab. See [[RegoDust]] control.]<br />
*The suit and equipment room is quite large and will presumably be well ventilated*. On the other hand, the living quarters and lab will be relatively congested, and we wouldn't want to bring lunar regolith into this clean living area due to its toxic nature (which we don't fully understand, and need to study). Therefore I suggest we designate one or more of the gear storage areas in the suit and equipment room as a lab bench, specifically for studying physical and chemical properties of the lunar regolith. Many of these studies will need to be conducted outside of the habitat, but for the few that will need to be conducted inside the habitat (exact studies yet to be determined by the [[OpenLuna Science]] team; suggestions welcome), this space would be ideal.<br />
<br />
<br />
== An alternate possibility for the Outpost ==<br />
[[Image:Igloo_Layout-1.jpg|thumb|900px]]<br />
<br />
[[User:Len|Len]] 29 November, 2009 An 8 meter dia igloo provides approximately 50 square meters of floor space. The center column could contain a light tube to bring sunlight from the surface to solar panels under the circular work surface. An outer shell for the center column would serve as a center support for the dome.<br />
<br />
[[User:Navigaiter|Navigaiter]] 01:48, 8 December 2009 (UTC) This round hab feels good. I'm looking forward to seeing how you prefer to attach the floor. I think it should just mirror the roof for simplicity and faster construction. How are the dome ends attached to the cylinder walls? An advantage is that this could be made from nasa external H2 tanks. We all know how eager nasa is to help the civilian space program.

<br />
First note that we are not now, and do not ever plan on becoming a Google Lunar X-Prize team, even though we work with one. (and are open to working with others.) Having said that, The Google Lunar X PRIZE is a $30 million international competition to safely land a robot on the surface of the Moon, travel 500 meters over the lunar surface, and send images and data back to the Earth. Teams must be at least 90% privately funded and must be registered to compete by December 31, 2010. The first team to land on the Moon and complete the mission objectives will be awarded $20 million; the full first prize is available until December 31, 2012. After that date, the first prize will drop to $15 million. The second team to do so will be awarded $5 million. Another $5 million will awarded in bonus prizes. The final deadline for winning the prize is December 31, 2014. More can be found at [http://www.googlelunarxprize.org GLXP website]. In case they change the rules, see our plan to win as [[Mission_X]] But also see [[GLXP]] as to why we will not enter unless they do so.<br />

The following is an abstract for a suit presentation. It guides how Paul thinks about suit design.<br />
<br />
Abstract - Next Generation suit designs, taking lessons from current analogue suit designs.<br />
Paul Graham, OpenLuna Foundation<br />
London, Ontario, Canada <br />
<br />
<br />
With the resurgence in interest and activity to return to the moon and Mars, significant thought must be<br />
given to Space Suit, Lunar Surface Suit (LSS), or Mars Surface Suit (MSS) designs. Factors that need<br />
to be considered include physical, data, and human factors issues. Specifics include items as mission<br />
duration requirements, availability of consumables replenishment, power utilization, waste<br />
management, communications, data management, entertainment and other user needs. Since the<br />
physical requirements are defined by the mission profile, they will be considered as baseline<br />
requirements. Also some data and human factors needs will also be considered as baseline<br />
requirements, others are more flexible, and should be driven by the individual mission and operators<br />
needs. These needs would best be defined through extensive analogue testing in a relevant environment<br />
performing realistic and relevant tasks. Therefor, this author believes that analogue suits should be<br />
designed as close as practicable to their real counterparts, and real suits should be designed from the<br />
lessons learned in the use and testing of their analogues. Since 2001, the author has been overseeing<br />
operations at the Mars Desert Research Station (MDRS) and Flashline Mars Arctic Research Station<br />
(FMARS), Observing simulations using primitive analogue suits, and gathering data on suit<br />
functionality from the perspective of the experienced field scientists and engineers who use them. Also,<br />
the author has been working directly with the OpenLuna suit development team in the design of their<br />
LSS. Using the process described above, OpenLuna will be developing a LSS that will meet or exceed<br />
their own, and NASA requirements. Beyond the minimum physical requirements, such as a 120 hour<br />
continuous pressurized time for NASA's Constellation needs for their Lunar Design Reference Mission<br />
(LDRM), close examination of existing analogue usage suggests that the following features should also<br />
be included in both analogue and space-worthy suits; an internally available food supply, drinking<br />
water supply, carbon dioxide, liquid and solid waste disposal, in-suit communications and navigation<br />
with redundant systems, temperature control, remote medical access, long duration radiation shielding,<br />
personal in-situ resource utilization, environmental protection, mobile power sources, and resource<br />
recycling. Rescue and recovery of an injured explorer or a damaged suit should be considered. Along<br />
with these basic physical needs, other features should be included such as enhancements in assistance<br />
for scientific studies, in-suit documentation, recording, and location capabilities. Available to the<br />
wearer should be local copies of engineering or scientific documentation, mapping and other data<br />
resources. Entertainment should be considered to help maintain morale during long transits, tedious<br />
tasks, or during emergencies. Lastly, the suit must be modular, inexpensively manufactured, easy to<br />
maintain and clean, durable enough to provide physical protection and must be able to operate in a<br />
wide variety of environments, with variable outerwear for special needs. All of the features should be<br />
extensively tested in an analogue environment before introduction into space-worthy suits, and any<br />
changes in the real suit needs should be reflected in their analogue counterparts.<br />

Two WEEKS in a suit?! Why?????<br />
Pardon my outburst. . .I meant no disrespect.<br />
I have been working on this issue for awhile and am currently pursuing this approach: It's called the 50/50 design. The spacesuit begins with a pressure/thermal protection garment with an oxygen breathing system, small heat rejection module and CO2 scrub unit. Very basic. This unit is worn during launch from Earth, all maneuvers in space and the lunar landing. Maximum capability for each O2 fill is only two to four hours, depending on level of activity. <br />
<br />
On the Moon - before doing anything else - the astronaut must access a pre-landed logistics module and add several elements to the basic suit. These include larger life-support module able to sustain ten hours of activity per charge, a hard, one-piece upper 'carapace' that has computer, with head-up display, communications and even external lights. This unit is bulky, relatively heavy and completely out of the question for use during lunar flight; it stays on the Moon and is used over several missions.<br />
<br />
A second unit attached to the right hip section is a thermal management system about the size of a loaf of bread but conforms to the shape of the hip. It cycles a 60/40 water/glycol mix through a series of bladders capturing the astronaut's excess body heat. <br />
<br />
A third unit on the left hip is the waste management system. You can probably guess how that works. In the front, between the two sections just described, is a tool box. <br />
<br />
When this unit is attached, the astronaut switches to an oxygen/ntrogen mix that is lower than terrestrial pressure with a higher O2 percentage.<br />
<br />
During flights, if there is a problem with the cabin pressurization, the astronaut simply umbilicals dirctly to the spacecraft O2 supply, bypassing the cabin distribution system.<br />
<br />
______<br />
<br />
In response to "Two WEEKS in a suit?!"<br />
<br />
Well, We we trying to save weight every way possible, and having a shelter or capsule just add weight, and bring little more than comfort to the operation. So, we are going to drop the comfort to save cost. Your design, although very well thought out, wouldn't work real well for us, for one thing, we won't need a cooling garment, we're currently focusing on MCP, (although we are considering something along the lines of the NDX-2) and, since we are running without a capsule, we will be flying in the MCP/HUT hybrid system. Also, something I discovered during my many thousands of hours SCUBA diving, the worst part of diving is putting the wet suit ''back on''. I'd rather just get used to the wet nasty suit, and keep wearing it, rather than get in and out of it. We will bring a light, inflatable "tent" for emergency cleanups or getting a nasty wrinkle out, but it is not intended to be used continuously.<br />
<br />
I will post more about my current thinking on suit design ofter the paper is presented at IAC.<br />
<br />
Never forget though, this is an open project, and I could be wrong. We will never take a "That's just the way it is, deal with it!" stance when there are facts to point in the other direction, we are entirely fact and demonstration driven. I'm building an analogue suit just to test all of the concepts for the suit, and intend to actually spend three weeks in the suit, eating, sleeping, and all else that would be expected. (Yes, Waste management is my biggest concern.) You are welcome, no '''''invited''''', to do the same. If your design is superior, it '''''will''''' be the one that flies...<br />

requirements. Also some data and human factors needs will also be considered as baseline<br />
requirements, others are more flexible, and should be driven by the individual mission and operators<br />
needs. These needs would best be defined through extensive analogue testing in a relevant environment<br />
performing realistic and relevant tasks. Therefor, this author believes that analogue suits should be<br />
designed as close as practicable to their real counterparts, and real suits should be designed from the<br />
lessons learned in the use and testing of their analogues. Since 2001, the author has been overseeing<br />
operations at the Mars Desert Research Station (MDRS) and Flashline Mars Arctic Research Station<br />
(FMARS), Observing simulations using primitive analogue suits, and gathering data on suit<br />
functionality from the perspective of the experienced field scientists and engineers who use them. Also,<br />
the author has been working directly with the OpenLuna suit development team in the design of their<br />
LSS. Using the process described above, OpenLuna will be developing a LSS that will meet or exceed<br />
their own, and NASA requirements. Beyond the minimum physical requirements, such as a 120 hour<br />
continuous pressurized time for NASA's Constellation needs for their Lunar Design Reference Mission<br />
(LDRM), close examination of existing analogue usage suggests that the following features should also<br />
be included in both analogue and space-worthy suits; an internally available food supply, drinking<br />
water supply, carbon dioxide, liquid and solid waste disposal, in-suit communications and navigation<br />
with redundant systems, temperature control, remote medical access, long duration radiation shielding,<br />
personal in-situ resource utilization, environmental protection, mobile power sources, and resource<br />
recycling. Rescue and recovery of an injured explorer or a damaged suit should be considered. Along<br />
with these basic physical needs, other features should be included such as enhancements in assistance<br />
for scientific studies, in-suit documentation, recording, and location capabilities. Available to the<br />
wearer should be local copies of engineering or scientific documentation, mapping and other data<br />
resources. Entertainment should be considered to help maintain morale during long transits, tedious<br />
tasks, or during emergencies. Lastly, the suit must be modular, inexpensively manufactured, easy to<br />
maintain and clean, durable enough to provide physical protection and must be able to operate in a<br />
wide variety of environments, with variable outerwear for special needs. All of the features should be<br />
extensively tested in an analogue environment before introduction into space-worthy suits, and any<br />
changes in the real suit needs should be reflected in their analogue counterparts.<br />

Two WEEKS in a suit?! Why?????<br />
Pardon my outburst. . .I meant no disrespect.<br />
I have been working on this issue for awhile and am currently pursuing this approach: It's called the 50/50 design. The spacesuit begins with a pressure/thermal protection garment with an oxygen breathing system, small heat rejection module and CO2 scrub unit. Very basic. This unit is worn during launch from Earth, all maneuvers in space and the lunar landing. Maximum capability for each O2 fill is only two to four hours, depending on level of activity. <br />
<br />
On the Moon - before doing anything else - the astronaut must access a pre-landed logistics module and add several elements to the basic suit. These include larger life-support module able to sustain ten hours of activity per charge, a hard, one-piece upper 'carapace' that has computer, with head-up display, communications and even external lights. This unit is bulky, relatively heavy and completely out of the question for use during lunar flight; it stays on the Moon and is used over several missions.<br />
<br />
A second unit attached to the right hip section is a thermal management system about the size of a loaf of bread but conforms to the shape of the hip. It cycles a 60/40 water/glycol mix through a series of bladders capturing the astronaut's excess body heat. <br />
<br />
A third unit on the left hip is the waste management system. You can probably guess how that works. In the front, between the two sections just described, is a tool box. <br />
<br />
When this unit is attached, the astronaut switches to an oxygen/ntrogen mix that is lower than terrestrial pressure with a higher O2 percentage.<br />
<br />
During flights, if there is a problem with the cabin pressurization, the astronaut simply umbilicals dirctly to the spacecraft O2 supply, bypassing the cabin distribution system.<br />

In response to "Two WEEKS in a suit?!"<br />
<br />
Well, We we trying to save weight every way possible, and having a shelter or capsule just add weight, and bring little more than comfort to the operation. So, we are going to drop the comfort to save cost. Your design, although very well thought out, wouldn't work real well for us, for one thing, we won't need a cooling garment, we're currently focusing on MCP, (although we are considering something along the lines of the NDX-2) and, since we are running without a capsule, we will be flying in the MCP/HUT hybrid system. Also, something I discovered during my many thousands of hours SCUBA diving, the worst part of diving is putting the wet suit ''back on''. I'd rather just get used to the wet nasty suit, and keep wearing it, rather than get in and out of it. We will bring a light, inflatable "tent" for emergency cleanups or getting a nasty wrinkle out, but it is not intended to be used continuously.<br />
<br />
I will post more about my current thinking on suit design ofter the paper is presented at IAC.<br />
<br />
Never forget though, this is an open project, and I could be wrong. We will never take a "That's just the way it is, deal with it!" stance when there are facts to point in the other direction, we are entirely fact and demonstration driven. I'm building an analogue suit just to test all of the concepts for the suit, and intend to actually spend three weeks in the suit, eating, sleeping, and all else that would be expected. (Yes, Waste management is my biggest concern.) You are welcome, no '''''invited''''', to do the same. If your design is superior, it '''''will''''' be the one that flies...<br />

Who ''are'' you? I'd like to see more.</div>Paul
