I can't emphasize the fun and things I learned from Kerbal Space Program. At the end of the series I am thinking of giving away a copy of KSP every once in a while to keep promoting the series to the newcomers. We (Steemit) are just expanding the reach of science to people all around the world, that weren't exposed to science until now, I love this!
RE: We have launched a rocket to MARS! Will it get there and how do we stop it once it's there?
