NASA announced a huge development in their space program: Astronauts can now tweet from the International Space Station. Previously, the crew had to email personnel who would then post it for them, but now they can go live and direct. Earlier today, Flight Engineer T.J. Creamer (@Astro_TJ) logged in and using the ultimate wireless internet connection ever, updated his Twitter, making him the first astronaut to do so unassisted, sorry @Astro_Mike.
