Record-breaking astronaut Scott Kelly retiring this April
Astronaut Scott Kelly, the International Space Station's selfie king, is retiring from his post at NASA on April 1st -- no foolin'. The American record-holder for most time spent in space will spend his foreseeable days still working on research following his year aboard the ISS, NASA writes, and will continue to provide medical samples at regular intervals.
Voice signals sent to Mars and back, while telephoto images tease rich geology
The Martian hills are alive with the sound of music. Well, NASA Administrator Charles Bolden's voice at least, as the agency reveals that the first recorded human voice has traveled from Earth, to another planet, and back. The words might not have literally echoed in the surrounding hills, but by having been beamed to Curiosity and back again, have made a small step towards interplanetary communication. Along with the motivational words of Bolden, the rover returned some telephoto images from the onboard 100mm and 34mm lenses. The pictures show the hills toward which Curiosity is bound, and tease the scientists with their rich-looking -- and hopefully revealing -- layers of geology.
