Rosetta shifts from sedate circular orbits to swooping flybys

Emily Lakdawalla • February 10, 2015 • 9

For the period of time before and after the Philae landing, Rosetta was able to orbit the comet close enough that it was in gravitationally bound orbits, circling the comet's center of gravity. As the comet's activity increases, the spacecraft has to spend most of its time farther away, performing occasional close flybys. The first of these is at 6 kilometers, on February 14.

At last! A slew of OSIRIS images shows fascinating landscapes on Rosetta's comet

Emily Lakdawalla • January 26, 2015 • 8

The first results of the Rosetta mission are out in Science magazine. The publication of these papers means that the OSIRIS camera team has finally released a large quantity of closeup images of comet Churyumov-Gerasimenko, taken in August and September of last year. I explain most of them, with help from my notes from December's American Geophysical Union meeting.

New Churyumov-Gerasimenko Shapemodel!

Mattias Malmer shares his latest shape model of Comet 67P/Churyumov–Gerasimenko, created using data from the Rosetta spacecraft.

Rosetta imaged Philae during its descent -- and after its bounce

Emily Lakdawalla • November 17, 2014 • 18

This morning ESA released a set of images of the Philae lander taken by the Rosetta orbiter during -- and after -- the lander's first touchdown. The images contain evidence for the spot Philae first touched the comet, and a crucial photo of Philae's position several minutes into its first long bounce.

Now Philae down to sleep

My last post on the drama in Darmstadt, where ground controllers believe Philae may have fell asleep for good.

Philae update: My last day in Darmstadt, possibly Philae's last day of operations

Emily Lakdawalla • November 14, 2014 • 18

Emily Lakdawalla gives a status report on Philae from the European Space Operations Centre (ESOC) in Darmstadt.

Philae status, a day later

Emily Lakdawalla • November 13, 2014 • 9

The Philae team scrambled all morning to comprehend the initially confusing status of the lander, and the picture is much clearer today. Speaking of which, there are lots more pictures!

Brief Philae "Morning After" update: First ÇIVA panorama from the surface

Emily Lakdawalla • November 13, 2014 • 1

I'm just getting up to speed on the news from overnight, which is mostly good: Philae remained in contact with the orbiter (which means the CONSERT radar sounding experiment was working), and it's sitting stably on the surface, although it's not anchored in any way. And they released the first ÇIVA image from the ground!

PHILAE HAS LANDED! [UPDATED]

Emily Lakdawalla • November 12, 2014 • 16

The landing happened on time just after 16:02 UT today! Philae mission manager Stephan Ulamec said: "Philae is talking to us! The first thing he told us was the harpoons have been fired and rewound. We are sitting on the surface." Those words later turned out not to be true; but we do know at least that Philae survived the landing and is returning good data.

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.
