Talk about Twitter’s reach growing. Apparently it is now going into outer space. NASA astronaut Mark Polansky will be commanding the upcoming mission to the International Space Station, and he just posted an invite on YouTube. This invite, which was posted on NASA’s official YouTube channel, invited users, as well as Twitter folks, to be a part of his next mission by submitting questions through YouTube and then following updates via Twitter.

After three unsuccessful flights, the fourth finally worked. SpaceX has managed to get their Falcon 1 space craft into space. Taking off from Kwajalein Atoll, an island in the South Pacific the Falcon 1 was able to fly into space, soaring above the International Space Station at a speed of 5200 meters per second. The flight of the Falcon 1 makes it the first ever private space craft to actually get into space.
