Philae update: Photo documentation of Philae's separation!

Emily Lakdawalla • November 12, 2014 • 4

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 update: "Go" for landing, despite apparent failure of cold-gas jet system [UPDATED]

Emily Lakdawalla • November 12, 2014 • 4

Philae is "go" for landing. But there has been drama overnight. One of the steps to prepare for landing did not proceed as planned. UPDATE: At 09:03 UTC, the lander separated from the orbiter, beginning a 7-hour descent to the surface of the comet.

Philae update: First of four "go-no-go" decisions is a GO!

Emily Lakdawalla • November 11, 2014 • 3

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 "go-no-go" decisions has been made, and it's a "go." Mission navigators have gotten data back from Rosetta that indicates that the spacecraft is on the correct trajectory to deliver Philae to the comet.

Report from Darmstadt: Philae status and early Rosetta results from DPS

Emily Lakdawalla • November 11, 2014 • 3

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 landing preview: What to expect on landing day

Emily Lakdawalla • November 05, 2014 • 8

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.

A (Difficult) Day in the Solar System

After a bad day on the launch pad, some perspective.

A feast of comet features from Rosetta at Churyumov-Gerasimenko

Emily Lakdawalla • October 27, 2014 • 22

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

Rosetta NAVCAM's Shades of Grey

Claudia Mignone • October 27, 2014 • 1

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.

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.

Philae's landing day announced as Rosetta swings to comet's dark side

Emily Lakdawalla • September 26, 2014 • 2

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, "site J," Earth should receive word of the successful landing at 16:00 UTC (08:00 PST). If they go to the backup site, "site C," news will reach Earth at about 17:30 UTC (09:30 PST). Mark your calendars!
