Mars orbiters plan for their October encounter with comet Siding Spring

Emily Lakdawalla • August 13, 2014 • 2

Now that we have reasonable confidence that our Mars orbiters will be safe from the close passage of comet Siding Spring, we are free to be excited about the opportunity that the encounter represents. At a community workshop on August 11, representatives from Mars missions shared their plans for great comet science.

Comet Siding Spring: Risk Assessment

Karl Battams • August 07, 2014 • 6

On October 19, 2014, Comet Siding Spring is going to have an extremely close encounter with the planet Mars. The bottom line: it seems most likely that our Martian spacecraft will be absolutely fine.

The Planetary Society Applauds ESA for Rosetta's Successful Comet Rendezvous

Jennifer Vaughn • August 06, 2014 • 1

The Planetary Society congratulates the European Space Agency on its Rosetta spacecraft arriving at comet 67P/Churyumov-Gerasimenko. Rosetta is the first spacecraft to orbit a comet.

Rendezvous with a crazy world

Daniel Fischer • August 06, 2014 • 2

Beaming scientists all around, spectacular images on large TV screens, and the best - or at least most exciting - yet to come: such was the extraordinary scene at the European Space Operations Centre in Darmstadt, Germany, today as the European Space Agency's Rosetta spacecraft reached its cometary destination.

"We're at the comet!" Rosetta has arrived at comet 67P

Emily Lakdawalla • August 06, 2014 • 9

After a journey of more than a decade, Rosetta has finally arrived at comet 67P Churyumov-Gerasimenko. Confirmation of the successful rocket firing came at about 9:30 UTC via a webcast from ESA's Operations Centre in Darmstadt, Germany.

Today's the day Rosetta arrives at a comet!

In less than a day, Rosetta will officially arrive, becoming the first spacecraft ever to orbit a comet! Watch an ESA Livestream of the arrival, and check out the latest photos.

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

Emily Lakdawalla • August 04, 2014 • 4

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.

[UPDATED] New Rosetta images show comet's craggy shape

A shift in position has brought shadows into view from Rosetta, outlining scarps and ridges on Churyumov-Gerasimenko.

New Rosetta view of the comet - and a comparison to other comets

Emily Lakdawalla • July 31, 2014 • 8

Rosetta's view of the comet is getting better and better. Today they released a new image from the high-resolution OSIRIS camera, and it's a very fresh one, taken only two days ago. Distinct features are coming into view. And it's finally detailed enough for me to compare it to the five other comets we've visited in the past.

Rosetta update: Long journey to a comet nearly complete

Emily Lakdawalla • July 29, 2014 • 4

A journey of nearly a decade is almost over. Rosetta is making its final approach to comet 67P/Churyumov-Gerasimenko, and the comet's strange shape is beginning to come into focus. As of today, the spacecraft is only 2000 kilometers away from the comet, and 8 days away from arrival.
