Sure, astronauts use compasses frequently, but on the Earth ground, not in space.

Compasses only work in two dimensions on a surface like Earth's, where there is a significant body of iron in the celestial body's core. Then only if the core is magnetiized, which it would most likely be, due to the spin of the celestial body.

Astronauts in space are in 3 dimensions, and in space there is no iron core to be magnetized. Compasses are useless in space, assuming they are far enough away from Earth to not pick up Earth's magnetic flux lines.
