Surviving on Mars
water
boiling point changes with Pressure
there is frozen water [low temp]
easiest source: poles [north pole]
groundwater [salty]
extracting from common minerals [hard, requires energy]
if it's liqutified it'll turn quickly to gas
it'll have to be recycled
mining regolith [long process yet feasible] [requires lot of energy]
underground [very hard, bc water cant exist in liquid form, has to be either solid or gas]
for 1 litre water, we need 7 kg of regolith to extract
ISS already has a Water Recovery System
oxygen and habitat
atmosphere
too little O2, too much CO2
its possible to extract O2 from CO2 [NASA] [MOXIE]
we can't breathe pure O2 due to pressure here in earth
using plants is smart

habitat
examples
inflateable -mars ice home
design considerations
easy to build and uses mars' resources
protection: from radiation and extreme temp
geodesic dome [HISEAS]
corrosive perchlorates
dust storms
3d print ice
3d print regolith
digging
hard for early stges requires heavy machines
might naturally occur while mining
but we can in low P
respiration will cause CO2 to increse
energy and radiation
solar [dust is a problem]
wind [atmosp s too thin]
