Space and Science BS Thread

Underground is just going to be safer. Domes are great and all, but too much risk. If anything I'd say the first big buildings will look more like stadiums with a retractable roof over the top dome. But that will probably have to wait for local resource harvesting.

It wouldn’t take much of a heat pump to manage that environment.

 

Neat!

Tbh I think surface dwellings at all aren’t in the cards in order to enable longer deployments. Buried over structures or better yet modified lava tubes(initially) and boring machine custom facilities (later on) will be what offers the amount of radiation shielding we’d need otherwise your looking at very short careers in space. The moon has no magnetic field or any other impediment to cosmic rays or radiation other than depth and nothing at all to stop or slow the constant rain of micrometeorites let alone anything large enough to be visible as a shooting star on earth. JWST barely arrived on station before getting holed. To start with we’ll have to hang our asses out but getting safely underground is a necessity long term. I want to see how big a 3D printer can be made to fit inside starship and utilize regolith as medium. We need to drop an articulated rov w/3D mapping into a few “skylights”, pick one and collapse a ramp and move in ASAP. Surface habs look good in pictures but both in terms of exposure and temperature swings they don’t make sense. I think we’re also going to need cubage for “mud rooms” (extra layers of air locks; first for vehicles, then for suits, then another for final decon) to keep the dust at bay And then off of each of those bays we’ll need separate spaces each for cleaning and maintenance, the kind of space which man made structures brought from earth can’t readily provide. The problem of charged particles and high static potential will also require solutions as well and I don’t think those can be escaped while on the surface in the very environment that causes them. Harnessing that potential would lessen the need to import solar panels also exposed to dust and impact damage, it’s just a different byproduct of solar radiation than we normally use.

See, yanno....I see more of William Christopher....you know, from Hogan's Heroes



AKA this guy, from that little known program...

I was l thinking kinda Gregory Peckish…

 

These are good thoughts. We already have 3D printed concrete houses. The hardest part would be getting water or some sort of epoxy to hold the regolith together.

They’ll probably figure it out fairly quickly..

 

I’d make it a priority to study both the dust and various bedrock formations and develop the means. This is one of those “it’s not about rockets but totally necessary” ancillary needs well suited to private sector collaboration with higher education as well as being fertile ground for start ups. It developes both the technology and the young experience in a field with hard to overstate growth potential. Exogeology and engineering for new design parameters. NASA could provide basic direction for submitted ideas but I’d like to see what others can imagine being useful ideas as well.

 

I’d like to see them try fusing it with lasers instead of having to import an extra binder or use water. We’ll need the water for other things. It’s an ideal environment for lasers and might also provide a means of cleaning/purifying air. Use the very stuff that’s so annoying to build with, that takes care of the disposal issue as well. Bind it into pellets that settle into a tray instead of clogging filters. And use the enormous static potential at the poles to provide the energy if the poles are where we are. Use the nature of each challenge to solve the problem it creates. Think of how to use it instead of getting rid of it.

 

I wonder if NASA is thinking this way, or if they are still focused on tubular ground level designs...

 

To get people there I suppose easily transported modules is what would be done but to me that’s akin to living out of an RV verses an actual dwelling. Not surprising given how we normally go about establishing a presence but it’s neither Kansas nor a Terran polar outpost and needs to do much more than simply hold air so a glorified Quonset hut won’t do. For those seeking a career in space exploration(or industrial development for that matter) having a single tour on the moon disqualify them from any further missions because of radiation exposure seems a poor way to gain the expertise we’ll need for the next steps. Limiting the exposure to transit times and actual lunar surface missions would allow them to gain experience and allow for repeat/extended missions. If the long term goal is to think long term then start as you mean to go on. Limit the stuff you have to send to the things that can’t be made there and make everything you possibly can. And get the hell under a big damn umbrella, preferably one several tens of meters thick.

 

So, the lunar landers during the Apollo missions...were those hardened against solar radiation?
