Following back-to-back space station resupply failures, a Russian Progress vehicle pulled into port this morning at the International Space Station.
Only two days remain until New Horizons' historic encounter with Pluto....two Pluto days, that is. Pluto and Charon rotate together once every 6.4 days, so as New Horizons has approached the pair over the last week, we've been treated to one stately progression of all of their longitudes.
Only about three weeks remain until the flyby — it's getting really close! I almost don't want the anticipation to end. New Horizons is now getting color images and is seeing features on Charon. Deep searches have yielded no new moons.
At Kennedy Space Center, NASA's ground systems program prepares for the first flight of the Space Launch System in 2018.
In a paper released in Geophysical Research Letters today, Eugene Shalygin and coauthors have announced the best evidence yet for current, active volcanism on Venus. The evidence comes from the Venus Monitoring Camera, which saw transient hot spots in four locations along a system of rifts near Venus' equator. They saw the hot spots in two distinct episodes in 2008 and 2009.
Three astronauts have returned to Earth, and while I'm happy that they landed safely, I'm very sad that astronaut Samantha Cristoforetti is not in space anymore to wish us "buona notte dallo spazio" with her lovely photos and piquant comments.
It’s been an eventful few weeks for Curiosity on Mars. From sols 981 to 986, Curiosity’s human pilots tried and failed to drive the rover southward; but, retracing their steps to Logan's Run, they quickly found a way up and into a beautiful geological amphitheater named Marias Pass, where they will stay throughout Mars solar conjunction. They also returned ChemCam to normal operations.
Pluto and Charon are growing larger in New Horizons' forward view, beginning to develop distinct personalities. A version of recent New Horizons photos processed by Björn Jónsson reveals an enigmatic dark line. Our maps of Pluto's surface are now as good as our maps of Mars and Venus, circa 1900!
It’s official: The sails are out. This afternoon, LightSail mission controllers downlinked a partial image of the spacecraft’s solar sails in space.
A jumbled JPG never looked so pretty. This afternoon, LightSail sent home pieces of two images taken by one of the spacecraft's onboard cameras.
Last week the New Horizons mission released a few new processed versions of their latest and greatest images of Pluto. They're the best images of Pluto that Earth has ever seen, but they're still a long way from what New Horizons will be able to show us, six weeks from now.
Fantastic new images of Ceres continue to spill out of the Dawn mission, and armchair scientists all over the world are zooming into them, exploring them, and trying to solve the puzzles that they contain.
