Mars Habitat 

Great comment!

Willy Makeit Well said 👏🏾👏🏾👏🏾

nice concept video and nice points, but i want to point out that's common in space applications for batteries to be considered the most crucial part of a spacecraft. The thermal control system of the craft will do everything in order to keep the battery at about room temperature in order to avoid battery degradation (that's happening very fast at +-200°C in (shadow/sun)) as a dead battery would mean the loose of the craft/mission. Fun-fact: Those non-consumer batteries f.i. for satellites can cost several million bucks :o (they shouldn't die/degrade significantly 200 cycles into their life (like that garbage in our smartphones) as for a satellite an orbit means ~1 battery cycle .... ~15 orbits/day in LEO ... lets say 5 years of life expectancy -> 5*365*15 = 27.375 orbits). Soooo.... the system of the rover will likely keep the batteries warm and comfy all the time :P

good points, especially the point about maintenance does not come up often and I just want to add a bit of input: 1. That the suits are on the outside is for the reason that the regolith is a very fine and very rough dust. not as bad as asbestos but still nasty, compare it to tiny glass shards. the idea of having the suits outside is to prevent the dust from entering the habitat. the regolith can lead to respiratory issues when inhaled and it is very difficult to clean the suits properly. these are some things they learned on apollo. 2. yea definitely true 3. well here are the same problems with the dust. as another commenter already stated the batteries of space systems have thermal control systems. lubrication is a nice topic to mention. there are some means of lubricating bearings in space (mars atmosphere is close to a vacuum). liquid lubricants can not be used. either the materials of the bearings are self lubricating or one can use solid lubricants. but getting wheels to work for long periods on mars is probably well understood given the science rovers (curiosity and opportunity etc.). so if the rover needs some maintenance it will be designed to be able to be repaired in the field or there is a replacement rover. you are right that the suits probably will not last long, but probably all exterior damage is going to be fixed and a spare suit will be used. spacesuits are really complex in their structure that you cant really repair them. however, they are working on methods to deal with the dust (like special cleaning methods and more resistant suits) so we will see what they come up with, but until now this is the state of the art.

Fullderp hi, thanks for your reply. I think that the Mars Society’s 21st annual conference had a video taped talk about an approach to dealing with the dust. It involved going through a liquid barrier. I have little confidence in those suits attached to the outside. One little mistake and you can explosively decompress the whole chamber. Additionally even these will have to be brought in for maintenance. What about covering the spacesuit with a loose fitting outer garment that can be exchanged for a clean one as necessary. Something like those hazmat suits should work.

Wait what? Their new proposal is way more beautiful. Unless you are confused about which one is new. This video is the old one.

Too much hassle because comparison video is beyond proximity.

Well, it's going even lower when it comes from Mars. ^^

Wow mars was like earth impresive

@@gourdey9806 Sorry, but I don't understand Marsian.

@@5mnz7fg Martian get it rite nub

Absolutely, easier to dig (cut and cover) or bore into some attractive landscape, the regolith 'glaze' lining is realistic , far less work , faster protection for martians, building and growing in a pressurised environment, not waiting for completion before putting up a plastic tent.

We'll just use starship

Mars surface pressure is 0.6% of Earths. So all you have to worry about is radiant cooling.

Of course they havent lol, this is computer graphics only and will remain so.

Of course we can we will b on mars in 4 years certainty

That's horrible

haha

badum tss

Right now, we don't know where hard rock is or how much overburden, the characteristics of the surface regolith etc, beyond samples of a few cubic inches. We have to start someplace with semi-permanent structures.

If only there were a man who had control over a few different companies in tunneling and high speed tunnel transport, maybe aerospace and transportation too. If he had a space exploration company that had experience in 3d printing on the cutting edge that would be great too. Is it too much to ask for experience with global, orbit based internet to also be in this man's toolkit? I wonder, does such a hero exist?

@@paulmoffat9306 I find it too restrictive that kind of reasoning. By now, we should already know how the composition is and if we really do not know then I suggest we send a probe to the landing location first. It is very "NASA" to come up with "semi permanent" and semi perpetual plans of approach. The US people really should start looking at them a bit more critical. Anyhow, there is no need for a first human settlement on Mars to be above ground, at least not until we are settled and are way more capable in construction. Despite of the unknowns of sub marsian conditions, it is just WAY simpler to sent a tunnel boring machine that will start snaking itself a way below ground. Microwave could be use to reinforce the side walls and/or composite panels can be used. Tunnel boring here on Earth work in similar ways.

@@patrickmalone1373 Indeed.. indeed ;-)

It might be, but the people there live in houses and apartments etc.!!!! There are lots of Tiny people two, 1-2 inches tall...I have lots of pictures!!!

no it doesnt, there are numerous large craters on Mars. There's hardly any atmosphere.

around 60-70 years. Human life expectacy is 74 now ,and in 10 years it will be 100.. so you can witness this, unless you lose interest lol.

Nikorasu Kon lol no. I would say 15-20 years. This is due to private companies making space travel many times cheaper.

I don't think you're an engineer.

YES AGREE

Ey oh! They willeat tubby tustard

They will test obv.

You make up 90% of that rat race mate

@@dcdeezcheesynutzsvideos7250 I have 3 up thumbs, you have zero...I win.

Getting underground will involve big engineering surely. Busting rock will be impossible without heavy equipment.

Ay caramba!

That's what the shell is for lol, to block the sun radiation.

It's not seen as a substitute, it's seen as a supplement. We're not abandoning Earth to live on Mars, We're going to live on both Earth and Mars, which significantly reduces the risk of our species going extinct

@@aaronjacobs3980 Yes but you do realize that there will exist an inter_dependency between Mars and Earth. There are vital things humans need which are not found on Mars. Now those essentials will be supplied from Earth to Mars and an inter_dependency between the two worlds will emerge.

@@horizontalmapping7033 for now yes, but it will go the same way as the European colonisation of the Americas (without murdering millions), where our small bases can evolve into self sustaining colonies/nations/whatever they'll be called

You only need like a foot of regolith in order to shield the space from radiation.

@@Azurryu For the Earth, that would be a good thing. Humans are the parasites of the earth.

Yes we will

You have a point, but perhaps people said something similar to Erikson or Colombus, or Magellan. I don't think humans should ever satiate our thirst for discovery and innovation. In the off chance we have an Armageddon type event happen Ben Afleck and Bruce Willy are not going to drill their way out of that one, it'd be nice for our species to continue to exist in the event of cataclysm.

@@Dave-wy4so ...getting in a boat and going somewhere is something most people could and would do...making discoveries on earth is natural....but you could literally put all the people who are in the gone to space club in a small boat...its just sci fi fantasy ...and doesnt do anything but create jobs....nobody leaves

In the future people are going to live on another planet, no matter what some dumbass like you have to say about the matter. It's only a matter of time when we have the technology to set up a permanent base on mars, we already have tons of people volunteering to go.

Except they are www.mars-one.com/news/press-releases/78000-sign-up-for-one-way-mission-to-mars

@@None888. As was already pointed out to you, there are thousands of people volunteering to go. Yes, we get it, you wouldn't. They will. Also this bullshit mantra of what's "natural"... Do you think it was "natural" for people to live for months on boats? Was it "natural" for people to cross mountain ranges in conditions they never experienced? Is it "natural" to fly a plane, climb Everest or explore the sea bottom in a submarine?
