Recently named the best place to work in the federal government for the fourth year in a row, NASA is looking for the best candidates to work in the best job on or off the planet. The astronaut candidate application website now is live and accepting submissions through Feb. 18. Qualifying U.S. citizens may apply at:

NASA astronaut Shannon Walker and astronaut selection manager Anne Roemer will answer questions about the job, and the application and selection processes. Anyone may submit questions at: http://www.reddit.com/r/IAmA/ 

The race to get humans on Mars has begun. SpaceX’s Elon Musk has said he thinks he can get humans to the Red Planet by 2026. Mars One says that its crew will land on Mars just a year later, in 2027. Nasa’s timeline has humans in Mars orbit by 2033, and on the surface of the planet by 2039. The European Space Agency (Esa) is also eyeing a 2033 Mars mission, while China’s space programme is looking at putting people on Mars between 2040 and 2060. The Martian surface might start to look quite crowded.
When these crews land, they’ll be representing their companies and countries. As they each build colonies and research stations and living facilities on Mars, they’ll be expected to report back to those entities.

Light travels so fast it can make the transatlantic journey between London and New York more than 50 times each second. With speed like that, you might wonder why there’s any interest at all in finding faster-than-light communication. But there is. With the vast distances between objects in deep-space, even messages travelling at the speed of light take an appreciable time to arrive. The bad news is that it’s impossible to send communications any faster without breaking established laws of physics – but the good news is that some workarounds have been suggested, which hold the tantalising promise of allowing for faster-than-light, or “superluminal” communication.
