Mighty Space Miners (1994)

Original title: おいら宇宙の探鉱夫

When disaster strikes an asteroid mining colony, who can the trapped miners call? No one! That's why only the bravest and most resourceful of individuals can ever become space miners, the hardworking pilots, scientists, and technicians who keep Earth supplied with priceless metals and isotopes from deep-space asteroid mines in the year 2060. When a military satellite triggers a catastrophic disaster, the colonists must cope with a world turned literally inside out with a nuclear reactor that threatens to turn the entire asteroid into a miniature sun in a matter of hours!
