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

(Web Page; Mon Jan 26 12:01:00 CST 2015)

Last week a suite of eight peer-reviewed papers were published in Science magazine, detailing the first results of the Rosetta mission. The papers are open-access, so you can go read them all if you want. And don't miss the supplemental ...

Description: 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.

32. Son of Rosetta

(Web Page; Mon Apr 23 02:10:00 CDT 2012)

On the heels of the news last week that the Rosetta spacecraft was spotted by sky surveys and briefly named among the minor planets as 2007 VN84 came another close approach by a newly discovered near-Earth object, designated 2007 VF189, ...

33. Rosetta and Glaciers

(Web Page; Mon Apr 23 02:01:00 CDT 2012)

Just pointing you to two new items on the website: I just posted a preview of the impending Rosetta flyby of the asteroid Steins, about 30 days away, including an encounter timeline. And there's a new installment -- the penultimate one,...

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

(Web Page; Wed Nov 19 15:33:00 CST 2014)

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. If the touchdown had happened nominally, one of these images would have shown Philae sitting...

Description: 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.

35. A new angle on Churyumov-Gerasimenko brings circular features into focus

(Web Page; Mon Aug 04 10:27:00 CDT 2014)

It's just two days now until Rosetta arrives in its initial 100-kilometer "orbit" of comet Churyumov-Gerasimenko, and the latest view from Rosetta's NavCam is fascinating. It doesn't look like a rubber duck anymore; several people have t...

Description: It's just two days now until Rosetta arrives in its initial 100-kilometer "orbit" of comet Churyumov-Gerasimenko, and the latest view from Rosetta's NavCam is fascinating. Circular features on the comet remind me of Tempel 1 as seen by Deep Impact and Stardust.

36. DPS 2015: A little science from Rosetta, beyond perihelion

(Web Page; Thu Nov 19 15:33:00 CST 2015)

Since I wasn't able to attend the European Planetary Science Congress last month, the Division for Planetary Sciences meeting was my first opportunity to see science results from the Rosetta mission since comet Churyumov-Gerasimenko pass...

Description: Updated numbers for physical properties of the comet, and a few interesting images of surface features and surface changes on Churyumov-Gerasimenko.

37. ESA's cool new interactive comet visualization tool based on amateur imaging work with open data

(Web Page; Thu Aug 13 13:54:00 CDT 2015)

A terrific new visualization tool for comet 67/P Churyumov-Gerasimenko demonstrates the value of sharing mission image data with the public. The browser-based tool lets you spin a simulated 3D view of the comet and change lighting condit...

Description: A terrific new visualization tool for comet 67/P Churyumov-Gerasimenko demonstrates the value of sharing mission image data with the public. The browser-based tool lets you spin a simulated 3D view of the comet. It began with a 3D model of the comet created not by ESA, but by a space enthusiast, Mattias Malmer.

38. Rosetta is closing in on Earth

(Web Page; Mon Apr 23 02:11:00 CDT 2012)

We're less than an hour away from Rosetta's Earth flyby; closest approach will happen south of South America at 20:57 UTC. The Rosetta flyby blog has some neat photos of screens of data being transmitted real-time from the spacecraft. ...

39. Rosetta's zeroing in on Steins

(Web Page; Mon Apr 23 02:01:00 CDT 2012)

As of midnight last night (UTC, so that's about 17 hours ago now) ESA's Rosetta spacecraft has all its science instruments on, getting ready for its first close encounter with an asteroid. The closest approach to 2867 Steins happens at ...

40. Pretty pictures: Rosetta's comet is now acting like one!

(Web Page; Thu May 15 10:17:00 CDT 2014)

As Rosetta crosses the last couple million kilometers separating it from its target comet, the spacecraft is snapping away with its OSIRIS camera. They take these images primarily for optical navigation -- to help steer toward the destin...

Description: New photos from ESA's comet-chaser show its destination comet, 67P/Churyumov-Gerasimenko, developing a coma.
