Is there any satellite that uses LOX as oxidizer?

In short: no. LOX, or any cryogenic fuel will slowly warm up without active cooling, resulting in boil off. Since satellites normally want long duration station keeping, this is non-ideal. As such, ...

Is there any satellite that uses LOX as oxidizer?

Although no satellites have been deployed using LOX for satellite propulsion, there is no fundamental (as opposed to practical) reason why it could not be done. LOX will only boil off until it reaches ...

Is it ever normal to vent LOX from spacecraft with active engines? Isn't it a fire hazard?

Until the OMS-1 burn was made unnecessary by tweaking the MECO targets, the Space Shuttle did this all the time. Residual LOX was dumped during the OMS-1 burn. LO2 propellant residuals are dumped ...
