Notes from Day 5 of the EPSC/DPS meeting: Saturn's storm, Phobos, and Lutetia

Emily Lakdawalla • October 07, 2011

Today was (is) the last day of the Division of Planetary Sciences / European Planetary Science Congress meeting in Nantes, France.

Watching Phobos pass by Jupiter

Emily Lakdawalla • June 17, 2011

Here is a really cool view of Phobos in the foreground with gigantic (but very distant) Jupiter sitting in the background, a fortuitous alignment that the Mars Express High-Resolution Stereo Camera team took advantage of on June 1.

Rosetta has entered its long sleep

Emily Lakdawalla • June 14, 2011

One big space event that I missed while I was on vacation was Rosetta's entry into hibernation. Rosetta is the biggest interplanetary spacecraft that has been launched by ESA, and it has the groundbreaking goal of entering orbit around a comet and dropping a lander onto it.

Place names on Lutetia

Emily Lakdawalla • April 26, 2011

Whenever we explore someplace new -- a new island, a new continent, a new cave, a new world -- there's a necessary activity that explorers must perform before they can sensibly tell the world about their discoveries: name things.

365 Days of Astronomy Podcast: What's up in the second quarter of 2011

Emily Lakdawalla • April 07, 2011

Regular readers of this blog will find the content of today's 365 Days of Astronomy Podcast familiar, because it's an update on what the solar system exploration spacecraft are up to, based on my monthly "what's up" updates.

What's up in the solar system in April 2011

Emily Lakdawalla • March 31, 2011

April 2011 will see MESSENGER begin the science phase of its orbital mission at Mercury, and should, I think, also see the start of Dawn's approach observations of Vesta. At Mars, Opportunity is back on the road again, rolling inexorably toward Endeavour. At Saturn, Cassini will continue its focus on Saturn and Titan science.

What's up in the solar system in March 2011

Emily Lakdawalla • February 28, 2011

I don't think there's any question what the big event of this month will be: MESSENGER is finally, finally entering orbit at Mercury on March 18 at 00:45 UTC (March 17 at 16:45 for me).

Rosetta Update: 98% of rendezvous burn achieved, more detail on the safing event

Emily Lakdawalla • February 22, 2011

ESA's Rosetta comet chaser has achieved 98% of the velocity change that it needed to accomplish in order to set itself up for the final leg of its cruise to comet Churyumov-Gerasimenko. The original plan was to perform this velocity change in a series of five rocket burns at the end of January, but the plans were interrupted by a scary event: the spacecraft went into safe mode during the second burn, on January 18.

Rosetta update: Scary safe mode, but all's well now

Emily Lakdawalla • February 04, 2011

The Rosetta blog has been strangely quiet of late, after they had been quite actively posting updates on the status of Rosetta during a critical series of orbit adjustment burns, which I wrote about two weeks ago.

Rosetta burns for its comet

Emily Lakdawalla • January 18, 2011

Rosetta -- Europe's comet-chasing spacecraft -- is in the middle of a three-day series of rocket firings that are setting the geometry for its rendezvous with comet 67/P Churyumov-Gerasimenko.
