Bye-bye, Curiosity
A few fortunate (and forward-thinking) skywatchers looked upward in the hours after Curiosity's launch and were able to see the spacecraft leaving Earth.
How did they make the nuclear power source for the Curiosity rover?
Maybe it's because I was a kid during the Cold War; I always assume that information about anything nuclear only comes out on that
Curiosity is on its way to Mars!
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.

Jason Davis put together this neat summary of the checkered history of Mars exploration.
Brief contact made with Phobos-Grunt after two weeks of silence
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.
Curiosity in context: Not exactly "Viking on wheels," but close
As I was beginning my research for my two magazine articles on the Curiosity rover's upcoming mission to Mars, I needed to figure out for myself how exactly this gigantic, ungainly machine fit in to the context of past Martian missions.
Phobos-Grunt status, launch plus six days
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.
Phobos-Grunt summary, three days after launch
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.
Phobos-Grunt status, two days after launch
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.
Phobos-Grunt, the morning after
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.
A serious problem on Phobos-Grunt
It looks like something has gone wrong with Phobos-Grunt.
Phobos-Grunt and Phobos LIFE, with Yinghuo-1, have launched!
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.
Phobos-Grunt and Yinghuo-1 poised for liftoff
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.
Phobos-Grunt and Yinghuo-1 now encapsulated in their fairing (lots of photos)
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!
Curiosity stacked for launch, still waiting for plutonium power source installation
It's still three weeks until Curiosity's launch date, but the spacecraft has already been placed on top of its rocket. The Kennedy Space Center's Curiosity photo album now has lots of pictures of the spacecraft being enclosed inside the payload fairing (the rocket's
Print publications galore!
November has already been a very good month for me in the print publication realm. I've had published not one, but two, feature articles on Curiosity, the Mars Science Laboratory rover.
