Did you use FL Studio?
The beginning was good (very nice ambience!), but when the congo-like drums came in, the song became a little worse. You need to mess with the volume of each individual note and make it differentiate more. It will make it sound more realistic.
It seems a little fast for your description "Deep under the surface of an asteroid mining operation." Then again, that's just a description, so I won't critique it.
I DID like the beat though.
