      Consider two astronauts who are in deep space and therefore are isolated from influences by any other bodies. If the astronauts push on each other, then, according to Newton's third law, the two forces are equal in magnitude and opposite in direction (Fig. a).That is, astronaut pushes on astronaut with exactly the same force (oppositely directed) with which astronaut pushes on :// Save $$ on textbooks.

It is very space and water efficient and can also be part of a closed-life support loop (oxygen regeneration, water filtering and food production).

The crew of the ISS have had many issues with their machines for generating Russian Elektra, and the US OGS for splitting water to make oxygen, and the Sabatier system for recycling CO 2 have all had issues, needing to be fixed, and sometimes not functioning for long periods of time.
