Help Mission Stuck - satellite repair in Prien

[tsavo]

After deplyed 5 satellites, the guy recommend me to USS for a new mission, and it turns out to be another satellite mission.

So I went on with my classmate to meet his agent, and then to Prien(correct?) to find the device hidden in an asteroid, I also got 10 robots in my cargo bay.

But, when I reached the spot, nothing happens.

I've tried everything: checking every possible locations for another device, jump through stargates(only get u killed or mission cancelled).

For the sake of 750G reward, I'm not to give up this mission, but what should I do now?
