If be alone,an astronaut is in a small member cabin, so live time basically is fixed. How long can basically depend on alive aerobic remnant how many. The power source dot in using spacecraft at most sees one part water, make take oxygen, but the quantity is too little at job of no help.
The time that prolongs life should accomplish " 3 reduce " .
The first, reduce motion, with reducing physical ability use up, fat life puts time to grow than lath lath time for certain. Adipose the important energy that is human keep in storage, not be special situation, won't be used, adipose work out, begin to use up the protein inside body.
The 2nd, reduce oxygen as far as possible use up. To achieve energy, of the material inside body decompose need to use up oxygen to produce carbon dioxide. Except hold human body quiet beyond, make oxygen with the material that carry as far as possible.
The 3rd, reduce water use up. The metabolization inside human body leaves not of boiled water attend, be short of water for long to be able to produce metabolization substance toxic. Should reclaim on one hand water, want to build water on the other hand.
If be the spacecraft with international space similar perhaps station, astronaut people still can live for some time more. Record of current international space station is astronaut triumphant benefit, in sheet of international space station second waited for 340 days. Of course, this among be to supply airship provides supply.
International space station loses supply estimation to be able to last month of one or two, the person jumps over little importunate time to grow more. If international space stands a remnant one the individual's word, live more than one year should unchallenged. Between greater part time-sharing, astronaut should lean reasonable use supply to live. Cooperate what take oneself in international space station to go up electroanalysis oxygen of preparation of water system all.
This kind of oxygen makes equipment, through consuming the electric power that solar energy brings, electroanalysis water, oxygen can generate 12 pounds oxygen everyday, a person or a few people are used quite. The rest is hydric discharge aerospace.
Also can resemble " spark comes to help " in in that way oneself are planted some of food, can use the experiment in dimensional station lab to use soil only nevertheless the stuff of other perhaps and similar action will plant, still wasted precious water.
Idealer seek to live on means
Astronaut is in aerospace, what need most is many plant, many plant can produce photosynthesis, the oxygen that the plant after such photosynthesis releases is enough a person uses, and the carbon dioxide just that human body breath discharges is plant institute need, you need not worry about the problem of such word oxygen.
Next we need many source of water, such we can use the oxygen of hydric union in fuel storehouse, such fountainhead also arose, fountainhead is more than and OK drinkable, also can irrigate to the plant, such you have the water that does not use to drink oxygen.
It is the food that we need next, in aerospace since can grow a vegetable, produce crop with respect to enough, and grain can be grown in aerospace, such word, we can have food.
