All about Budgets: Humans (and animals) breathe oxygen, consume water, consume proteins and carbohydrates, and many trace minerals and vitamins. We exhale Carbon Dioxide (CO2), excrete water and salts (and other things). It will always be a bit expensive to ship the inputs up the gravity well to people in settlements or space stations, so astronauts must also be farmers. Plants and algae can convert our wastes and CO2 using light of certain wavelengths and water into food and oxygen. Animals can also conver
Terraforming: What is Earth-like? To Terraform is to make a place Earth-like ('Terra' = earth). Using various methods over (very) long periods of time places like the Moon or Mars could be made Earth-like, a home for humans away from Earth where Earth-like ecologies can flourish. No place will ever be exactly like Earth, but some places like Mars, given enough effort can become somewhat more friendly to people and Earth life. To look at terraforming one should look at what we call Earthlike. Earth's atmosph
Outdoor temperatures should also be tolarable, espcially if we intend to have farms, praries, or forests. The temperature shouldn't swing beyond -40 C to +50 C (i.e. -40 F to 130 F) and should be between 3 C and 40 C (or between around 40 F and 105 F)for at least a few months a year at some region of the planet. The temperature range will need to match that of any Earth ecosystem or crop set we wish to grow. The Atmosphere should be thick enough to balance out temperature swings and store some of the day's
