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.
I woke up early Sunday morning to the dramatic news: Philae is back! With a few days to consider the telemetry, the Philae team is now talking about the science they hope to do. With comet Churyumov-Gerasimenko approaching perihelion in August, it's going to be an exciting ride.
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.
Tonight, for the first time, I glimpsed our spacecraft with my own eyes. It was just the faintest pinprick against the bright lights of the big city. But, there it was right on time and exactly per the coordinates.
With the team still trying to download an image from LightSail's second camera, Emily Lakdawalla processed a partial image from the first camera that contains a slice of Earth.
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.
Over the last several years, engineers at the Jet Propulsion Laboratory and Applied Physics Laboratory have rethought the entire approach to exploring Europa. NASA now has a concept that's affordable.
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!
The Planetary Society’s LightSail test mission successfully completed its primary objective of deploying a solar sail in low-Earth orbit.
It’s official: The sails are out. This afternoon, LightSail mission controllers downlinked a partial image of the spacecraft’s solar sails in space.
Our new Planetary Society headquarters building is on track to be ready for us by mid-July. The building, which once was a bank, is being converted into a contemporary office space customized for the unique needs of The Planetary Society.
Fifteen years ago, Society members and passionate space advocates like you helped save the Pluto mission. Now we can do the same for missions to Europa and Mars.
