A little fun with Deep Impact deep-sky data
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.
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.
Goldstone: Desert outpost performs radio imaging of close-passing asteroid 2005 YU55
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!
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.
How radio telescopes get "images" of asteroids
This is a repost of an article I wrote in April 2010; I thought it'd be useful reading for those of you interested in today's near-Earth flyby of asteroid 2005 YU55.
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.
Dawn Journal: HAMO successfully completed, LAMO ahead
Dawn has completed another wonderfully successful phase of its exploration of Vesta, studying it in unprecedented detail during the past month.
What do Dawn's color ratio images of Vesta mean?
The Dawn mission to Vesta continues to release an image every day, and recently they have been releasing lots of color images. I like color pictures for aesthetic reasons, but color is actually a very important property of planetary surfaces.
Mars Exploration Rovers Update: Opportunity Heads for New Discovery as Winter Blows In at Cape York
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.
NPP Earth observatory launched successfully, and I was there!
Well, that was awesome. The NPP Earth observation satellite launched successfully an hour or so ago, and I was with a chilled but thrilled crowd of a few hundred people to watch it at Vandenberg Air Force Base.
NPP Tweetup schedule and launch timeline
This evening I'll be headed up to Lompoc, California, to participate in my first Tweetup along with 25 other Tweeters.
Mars Climate Sounder confirms a Martian weather prediction
The Mars Climate Sounder team has recently confirmed a prediction of a weather phenomenon on Mars that we haven't been able to observe before.
Nighttime Water Ice Clouds Predicted by Models are Confirmed by MCS Observations
The Mars Climate Sounder instrument provides routine nightside observations of atmospheric temperature and opacity that document the presence of rapidly evolving water ice cloud layers in the Martian tropics during the northern summer season.
