Space oxygen???????? ?

They either take liquid oxygen in cryogenic containers or they produce the oxygen by a chemical reaction in what's commonly referred to as an Oxygen Candle. The candle is what caused the fires on the MIR space station.

The space station uses a machine to extract the oxygen out of water.

Spacecraft carry huge amounts of oxygen that the astronauts use to breathe. The supply can also be stretched further through air filtration, hydroponics, air scrubbers, and so on.

They take it with them.

Liquid Oxygen tanks.

come on, adult adult males... enable's assume the pill is in orbit. so is the oxygen. if the oxygen is vented, its nonetheless in orbit. optimistic, its going to disperse some, yet stay in orbit. Heck, its going 18,000 MPH. Even for O2 that's quite a number of momentum.

who's they????

but any oxygen seen to exist in space was formed in the centre of stars by fusion processes within the said star by combining lighter elements via fusion,that system that makes star shine..

Oxygen isn't "made" by humans anywhere. It is either obtained by decomposing water or some other oxygen containing compound (e.g. CO2).

They take it there.
