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.

Last week, the team put all of the data from Deep Impact's deep-sky imaging session online, and challenged visitors to see what they could make from it. I made some photos of M51, but there were some challenges.

Ever since the space shuttle Endeavour was awarded to the California Science Center I've been curious about the question of how they will ever get a shuttle from Los Angeles International Airport across more than 10 miles of densely developed city land in the United States to Endeavour's eventual home in Exposition Park.

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.

Anticipating the close flyby of asteroid 2005 YU55 yesterday, the Jet Propulsion Laboratory invited media to tour Goldstone, one of three facilities that make up NASA's Deep Space Network. I've always wanted to see these massive radio dishes up close, so I jumped at the chance!

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.

Unless you've been living under a rock you've probably heard that there is a relatively large (400-meter) asteroid passing closer to Earth than the orbit of the Moon today -- in just a few minutes, as a matter of fact.

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.
