ISS HTV Docking Simulator (ssl.tksc.jaxa.jp)

Expected this to be like the spacex docking simulator but its completely different and deals with more of the orbital mechanics rather than assuming that the acceleration due to gravity is constant.

Just WTF... maybe if I understood Japanese :D This is nothing like the SpaceX sim, KSP or ISS streams.

This was much harder than the spacex sim - took me 1 failure to get it right

Aw, it ends when you grab it with Canadarm. I would've liked to actually dock it to the ISS

Its a berthing simulator

For the first part, basically have to thrust up and left to keep the path going up the middle line.
