Donate to the Campaign to reboot ISEE-3 - http://www.rockethub.com/42228 ISEE-3 was a spacecraft launched in 1978 which originally examined the solar wind and plasma environments around the edges of the Earth-Moon system. In the Early 80's some fancy orbital mechanics and a lunar gravity assist was used to put the spacecraft into deep space to encounter a couple of comets. Now 30 years later it's coming back to Earth and could use some more orbital mechanics trickery to bring it back into earth's orbit, the only problem is that the technology required to talk to the spacecraft has been 'retired'. So a team at Skycorp is racing against time to build a replacement and command the spacecraft back into a captured orbit. ... https://www.youtube.com/watch?v=m4D6pRT04PY

It's been a long time since I looked at this game and it's continued to improve in early access now. The 2d universe exploration and ship building game implements a lot of ideas even though it's still in development. http://steamcommunity.com/app/392080 ... https://www.youtube.com/watch?v=3gvuTIcu5_c

Betelgeuse is the reddest star visible in the night sky, a red supergiant a few hundred light years from Earth it's likely to become a supernova in the next hundred thousand years or so. Recently it faded and became half as luminous as usual, and some more clickbaity publications suggested a supernova might be imminent. And that would be amazing. But don't place any bets on it, all the science suggests it's still young enough that it's burning helium, so we have plenty of time to watch it being Orion's shoulder.

'Doing it like Elon Musk' challenge was set to perform a powered landing of a capsule from orbit, but instead of nice throttleable Super Draco thrusters let's do it all with solid rocket boosters.
