71. Philae landing site selection process under way as Rosetta closes to within 60 kilometers of the comet

(Web Page; Tue Aug 26 10:37:00 CDT 2014)

When Rosetta arrived at comet Churyumov-Gerasimenko on August 6, it began its survey of the comet from a standoff distance of roughly 100 kilometers, though that number varied within a small range as the spacecraft executed its odd trian...

Description: Rosetta spent the week transitioning to a lower orbit from which it continues to observe the comet. This weekend, the mission will select about five landing sites for more detailed study. They have also now estimated the mass of the comet.

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

(Web Page; Tue Nov 11 03:04:00 CST 2014)

I arrived in Darmstadt, Germany yesterday and headed straight to the European Space Operations Centre, the base for ESA's spacecraft operations and my workplace for the next week. I'm here, of course, to cover the exciting Philae landing...

Description: 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.

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

(Web Page; Mon Aug 19 10:00:00 CDT 2013)

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 chan...

Description: 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.

74. Worth the wait: First public release of Rosetta science camera images of comet 67P

(Web Page; Thu Dec 17 00:30:00 CST 2015)

Finally! It has been a long wait, but so worth it: the Rosetta OSIRIS science camera team has delivered the first pile of data from the rendezvous with comet 67P to ESA's Planetary Science Archive. I have spent a good chunk of the last t...

Description: Finally! It has been a long wait, but so worth it: the Rosetta OSIRIS science camera team has delivered the first pile of data from the rendezvous with comet 67P to ESA's Planetary Science Archive. I have spent a good chunk of the last three days playing with the data, and it's spectacular.

75. What's up in the solar system, September 2016 edition: OSIRIS-REx launches, Rosetta ends

(Web Page; Mon May 22 19:31:00 CDT 2017)

The month of September begins with an annular solar eclipse visible from much of Africa on September 1, with the path of totality crossing Gabon, Congo, DRC, Tanzania, Mozambique, and Madagascar. Mid-month (on or after September 8), we'l...

Description: The month of September begins with an annular solar eclipse visible from much of Africa on September 1. On or after September 8, we'll see OSIRIS-REx launch into a two-year cruise toward a rendezvous with asteroid Bennu. But September will close, sadly, with the end of the wonderful Rosetta mission.

76. Mini mission updates: Dawn in orbit; Curiosity short circuit; Rosetta image release; Hayabusa2 in cruise phase; and more

(Web Page; Fri May 18 14:31:00 CDT 2018)

So much news from around the solar system this week! The major headline is that Dawn has successfully entered orbit at Ceres, becoming the first mission to orbit a dwarf planet and the first to orbit two different bodies beyond Earth. Al...

Description: Dawn has successfully entered orbit at Ceres, becoming the first mission to orbit a dwarf planet and the first to orbit two different bodies beyond Earth. I also have updates on Curiosity, Rosetta, Mars Express, Hayabusa2, the Chang'e program, InSIGHT, and OSIRIS-REx.

77. Rosetta's Lutetia pictures

(Web Page; Tue Aug 25 14:34:00 CDT 2015)

I saw these pictures for the first time just 10 minutes before boarding my flight back home, and forced myself to download everything I could find as quickly as possible without pausing to actually look at them. (Well, except for the Sat...

78. Adding Churyumov-Gerasimenko to my scale comparison of comets and asteroids

(Web Page; Mon Oct 05 15:30:00 CDT 2015)

I'm not sure how I missed this, but last December the Rosetta mission posted a color portrait of comet Churuymov-Gerasimenko. It's possible that I missed it because the comet is incredibly gray, having virtually no color variation anywhe...

Description: Having found a color photo of the comet, I finally added Churyumov-Gerasimenko to my scale comparison of comets and asteroids visited by spacecraft.

79. Lutetia -- and Saturn!!

(Web Page; Tue Aug 25 14:40:00 CDT 2015)

A quick post of just one of the gorgeous images from Rosetta's flyby of Lutetia today; for more, see the Rosetta Blog. But this one was just too pretty to wait for. The solar system is a very, very empty place. It is incredibly rare to ...

Description: 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!
