The RS-25 powered the space shuttle for three decades, and will soon be used on the Space Launch System. Is it still the Ferrari of rocket engines? A deep dive on performance, reliability and the politics of rocket science.
A team of scientists at the University of Arizona continue their efforts to extract data from more than 90,000 images captured during NASA's Surveyor program. In the meantime, new first-look images and an animation have been released.
May 2016 will be yet another month of fairly routine operations across the solar system -- if you can ever use the word "routine" to describe autonomous robots exploring other planets. ExoMars' cruise to Mars has started smoothly, and Juno is only two months away from Jupiter orbit insertion. Earthlings will witness a Mercury transit of the Sun on May 9.
