Hello,

Engineering on an astronomical scale, or astronomical engineering, i.e., engineering involving operations with whole astronomical objects (planets, stars, etc.), is a known theme in science fiction, as well as a matter of recent scientific research and exploratory engineering. 

Hope this helps you.

All the Best.

Hy there aspirant,

Astronomical engineering doesn't require much field work it deals with the space  and the studies of its surrounding. It has a lot of further scope . wishing you luck
