Algodoo

Fly up to the green dot with ARROW keys, hover 2 m above it, wait for a sattelite to pass by, chase it, undock your first stage by first pressing E, then pressing DOWN. Try to dock to the sattelite without shooting off into space or falling to the planet! (I havent tested if stage 2 can take off on it's own, be aware of that.)
Note:
-The springs let you know where Earth and the sattelite are, but do not exert forces.
-The red block on the front of your sattelite is adhesive, and your goal is to stick it to one of the grey faces of the sattelite.
-I managed to do it ONCE. It is possible.
Have fun!
