A report on a press briefing about Voyager 1 at the Fall 2011 American Geophyisical Union meeting. The spacecraft has entered a new region between our solar system and interstellar space, which scientists are calling the stagnation region.

After modifying two antennas and attempting to send commands to Phobos-Grunt for weeks without success, ESA has made the decision to stop tracking support.

In this update on the Dawn mission, project system engineer Marc Rayman reports that the probe is headed for its low altitude mapping orbit (LAMO), where it will focus on making a census of the atomic constituents and on mapping the gravity field in order to determine Vesta's interior structure.

What's going on with our planetary explorers in December?

It was a textbook launch for the Atlas V 541 today at 15:02 UTC, and within an hour after liftoff, the Centaur second stage had sent Curiosity on its way for an 8.5-month journey to Mars.

On Tuesday, November 22 at 20:25 UTC, a European Space Agency ground station in Perth, Australia, successfully made brief radio contact with Phobos-Grunt.

I said I wasn't going to post again unless the spacecraft talked to us, but I changed my mind because finally there were official comments today about the status of the mission from Roskosmos head Vladimir Popovkin.

I can summarize the news about the last day's efforts to save Phobos-Grunt in three words: there is none. At least nothing official.

When I last left Phobos-Grunt, Roscosmos had not yet commented on the results of a planned attempt to communicate with the wayward spacecraft at 19:00 UT on November 9.

I repeatedly rewrote yesterday's post on the problem suffered by Phobos-Grunt after its apparently perfect Zenit launch and thought it was time to begin fresh.

It looks like something has gone wrong with Phobos-Grunt.

I am ecstatic to report that at 20:16 UTC, millions of passengers on board the Planetary Society's Phobos LIFE biomodule launched into space inside the Phobos Sample Return (also known as Phobos Grunt or Phobos Soil) spacecraft.

Russia's Phobos-Grunt sample return spacecraft, carrying the Planetary Society's Phobos LIFE experiment, plus China's Yinghuo-1 Mars minisatellite, are poised for launch at Baikonur! The launch window opens in less than six hours, at 20:16 UTC.

About a week after Curiosity passed through the same milestone, Phobos-Grunt and Yinghuo-1 -- still slated for a November 8 launch -- were encapsulated in their payload fairing in preparation for being stacked on their rocket. And, of course, our little Phobos LIFE capsule is inside there too!

Dawn has completed another wonderfully successful phase of its exploration of Vesta, studying it in unprecedented detail during the past month.

The Chinese spacecraft Shenzhou 8 docks with space station Tiangong 1, on the same day a Progress resupply capsule arrives at the International Space Station.

Opportunity roved on this month, driving alongside the rim of Endeavour Crater toward the northern end of Cape York in search of more science gold and a place to hunker down for winter.
