81. An active comet, from a distance

(Web Page; Fri Feb 13 13:27:00 CST 2015)

As I write this, Rosetta has closed to within 50 kilometers of Churyumov-Gerasimenko, on its way to a very close, 6-kilometer flyby of the comet tomorrow. ESA posted a detailed blog about the flyby today, and how it is typical of Rosetta...

Description: Rosetta has closed to within 50 kilometers of Churyumov-Gerasimenko, on its way to a very close, 6-kilometer flyby of the comet tomorrow. To prepare for the flyby, Rosetta traveled much farther away, allowing it to snap these amazing photos of an increasingly active comet from a great distance.

82. Unseen latitudes of comet Churyumov-Gerasimenko -- revealed!

(Web Page; Fri May 15 11:55:00 CDT 2015)

Every thing in the solar system spins, from the biggest planets to the smallest asteroids. And nearly everything that spins, spins at an angle to its orbit. Therefore, nearly everything in the solar system has seasons. Comet Churyumov-Ge...

Description: A recent Rosetta image has revealed a good part of the comet's previously hidden southern terrain to the public for the first time.

83. Crescent Earth

(Web Page; Sun Mar 13 16:41:00 CDT 2016)

Just hours away from its Earth flyby, Rosetta is busily snapping images and gathering other science data. Among other things, it's using its spectrometric instruments to try to follow up on the Moon water discovery made by Chandrayaan-1,...

84. Opposition surge comet

(Web Page; Tue Apr 12 10:43:00 CDT 2016)

Today, the Rosetta OSIRIS team's Image of the Day is this highly unusual view of the comet with the Sun very nearly behind the spacecraft. As with all OSIRIS images, it is worth it to click through twice to enlarge it to its full size. H...

85. A right old comet kerfuffle…

(Web Page; Fri Jul 18 12:01:00 CDT 2014)

This article originally appeared on Stuart Atkinson's blog and is reposted here with his permission. If you have a passion for – or even just a passing interest in – space exploration, you’re probably aware that a ...

Description: A European space enthusiast, children's author, and volunteer astronomy outreach worker asks for more images from Rosetta.

86. What's up in the solar system, August 2016 edition: Juno to get Jupiter close-ups, Rosetta descending, road-tripping rovers

(Web Page; Fri Jul 29 17:02:00 CDT 2016)

Welcome to your solar system exploration update for the month of August, 2016! The thing I'm most excited about this month: we'll finally see JunoCam's first high-resolution images of Jupiter. We'll also see OSIRIS-REx making progress to...

Description: This month we'll finally see JunoCam's first high-resolution images of Jupiter. We'll also see OSIRIS-REx making progress toward its September 8 launch. Both rovers are road-tripping at Mars, while ExoMars Trace Gas Orbiter has completed a major mid-course correction ahead of its October arrival.

87. A feast of new OSIRIS photos from comet 67P

(Web Page; Wed May 11 16:19:00 CDT 2016)

Last week, the Rosetta mission released a large quantity of science data to the worldwide public. The release included data from many of its instruments, but I only have eyes for one of them, at least initially: OSIRIS, the high-resoluti...

Description: Last week, the Rosetta mission released a large quantity of science data to the worldwide public, including photos from the mission's close observation phase and the Philae landing.

88. Saturn from above

(Web Page; Sun Sep 10 19:55:00 CDT 2017)

OK, I had planned to confine my posts this week to Rosetta and New Horizons, but I could not let these images sit on my computer until next week. The Cassini imaging team has assembled and released two of the full-ring-system portraits t...

89. New Churyumov-Gerasimenko Shapemodel!

(Web Page; Thu Dec 11 17:58:00 CST 2014)

Here is my latest shapemodel of comet 67P Churyumov-Gerasimenko: It is as good as I believe can be done with the current limited data set of images that have been publicly released by the Rosetta mission. It was built by correlating 1...

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

90. Philae landing preview: What to expect on landing day

(Web Page; Wed Nov 12 03:11:00 CST 2014)

The timeline is up-to-date as of November 12 at 07:30 UTC. Ten years. That's how long it took Rosetta to get from Earth to comet 67P/Churyumov-Gerasimenko from its launch on March 2, 2004, to the beginning of its first orbit on August 6...

Description: 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.
