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.
Book Review: Atlas of the Galilean Satellites, by Paul Schenk
Not many subjects remain for which it is possible to assemble everything that we know about it in one book. Even for those subjects for which our knowledge is limited, knowledge seems always to be expanding exponentially. This is not true, however, for the Galilean satellites of Jupiter.
Is Europa's ice thin or thick? At chaos terrain, it's both!
Among Europa scientists there are two warring factions: the thick-icers and the thin-icers. The question is how thick is the ice shell that overlies Europa's subsurface ocean (the existence of which pretty much everyone agrees on).
Our friendly neighborhood asteroid, 2005 YU55 (an animation)
Last week JPL released two animations of asteroid 2005 YU55 made from the radar data acquired by Goldstone's 70-meter radio dish.
Book Review: A More Perfect Heaven, by Dava Sobel
As with her previous two books Longitude and Galileo's Daughter, Dava Sobel draws heavily on primary sources for her latest book, A More Perfect Heaven: How Copernicus Revolutionized the Cosmos.
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.
How to move a shuttle across Los Angeles
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.
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 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.
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.
Live feeds on asteroid 2005 YU55 as it passes Earth
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.
A serious problem on Phobos-Grunt
It looks like something has gone wrong with Phobos-Grunt.
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
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!
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.
Deep Impact goes for the deep sky
I love it when old spacecraft get pushed to perform feats that weren't part of their original missions.
