Philae update: Photo documentation of Philae's separation!
Here it is. We knew hours ago that Philae separation happened, but there's nothing like seeing a photo, seeing Philae's mothership receding into the distance.
PHILAE HAS LANDED! [UPDATED]
The landing happened on time just after 16:02 UT today! Philae mission manager Stephan Ulamec said:
Report from Darmstadt: Philae status and early Rosetta results from DPS
I'm reporting live from the press room at the European Space Operations Centre in Darmstadt, Germany. There's little news on Philae yet except that its status is good. Meanwhile, Rosetta scientists presented their first early comet results at the Division for Planetary Sciences meeting in Tucson, Arizona, which I watched from afar using Twitter.
Philae update: First of four "go-no-go" decisions is a GO!
It's been a day of calm before the storm here at the European Space Operations Centre in Darmstadt, as we get ready for the big event tomorrow: Philae's hoped-for landing on a comet. The first of four
Philae landing preview: What to expect on landing day
Earth's first-ever landing on a comet is a week away. On November 12 at 8:35 UT, Philae will separate from Rosetta. Seven hours later, it will arrive at the surface of the comet. Hopefully, Philae will survive the landing, and begin to return data.
Dawn Journal: Ion thrusting (or not)
Marc Rayman gives the latest update on the Dawn mission, focusing this time on the performance of its ion propulsion system.
The Art of Planetary Science
On October 17-19, 2014, the Lunar and Planetary Laboratory on the University of Arizona campus hosted the second annual Art of Planetary Science exhibition. This exhibition featured works of art inspired by the solar system, alongside works by scientists created from their scientific data.
Hayabusa2 nearly ready for launch: Photos from Tanegashima, and new artist's renderings
On October 27, JAXA provided media with an opportunity to view the Hayabusa2 spacecraft at the Tanegashima space center, where it's making final preparations for launch. Koumei Shibata was there, and took several photos. And artist Go Miyazaki has shared several terrific new renderings of the spacecraft in flight.
A (Difficult) Day in the Solar System
After a bad day on the launch pad, some perspective.
Rosetta NAVCAM's Shades of Grey
What do “light” and “dark” mean for an object like Comet 67P/C-G? Here are some details on how Rosetta's NAVCAM images are taken and displayed to make a wide range of surface features possible.
A feast of comet features from Rosetta at Churyumov-Gerasimenko
I have been horribly behind in posting images from Rosetta's exploration of comet 67P/Churyumov-Gerasimenko, and that's a shame, because the spacecraft has lately been exploring the comet from a range of only 10 kilometers. From that range, the NavCam gets sub-meter resolution, and we're seeing a menagerie of odd surface features
Collaboration Between OSIRIS-REx and Hayabusa2
The University of Arizona (UA) hosted representatives of the Hayabusa2 asteroid sample return mission to explore opportunities for collaboration with the OSIRIS-REx team.
What did Dawn learn at Vesta?
It's now been two years since Dawn wrapped up its work at the second-largest asteroid. What else did we get from the Vesta encounter besides great photos? Recently, I asked Dawn's deputy project scientist, Carol Raymond, for help in summarizing a few of the big things Dawn taught us.
Mattias Malmer's amazing 3D views of Churyumov-Gerasimenko
I'm thrilled to be able to share with you all a spectacular set of images of Rosetta's comet, produced from NavCam data by a master space image processing enthusiast.
Brief mission update: Hayabusa2 has a launch date!
JAXA announced the launch date for their Hayabusa2 asteroid sample return mission today: November 30 at 13:24:48 Japan standard time (04:24:48 UT / November 29 at 20:24:48 PST)
Dawn Journal: 7 Years of Interplanetary Travel
Marc Rayman gives us an update on the Dawn mission, heading to Ceres, on the 7th anniversary of its launch.
Philae's landing day announced as Rosetta swings to comet's dark side
ESA announced today that Philae will be landing on November 12, 2014. What time the landing occurs depends on which landing site they use. If they go to the prime landing site,
All That is Known About Bennu
The OSIRIS-REx Design Reference Asteroid (DRA) document is now available to the public. The DRA is a compilation of all that is known about the OSIRIS-REx mission target, asteroid (101955) Bennu.
