Checking in with NASA's Commercial Partners
Checking in with SpaceX's launch abort system progress, Boeing's CST-100 drop tests, and a recent Space, Science and Technology Committee meeting on Capitol Hill.
U.S. House of Representatives Hearing Next Week; Show Up to Show Your Support for Space Exploration
If want to demonstrate your support for planetary exploration -- and you're planning to be in the Washington, D.C. area next Tuesday, November 15, 2011 -- please consider adding your presence to the congressional hearing on
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.
365 Days of Astronomy Celebrates Sagan's Birthday
The 365 Days of Astronomy Podcast celebrated Carl Sagan's birthday yesterday by reposting my conversation with Ann Druyan, Sagan's Co-creator and life-partner. Links inside.
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.
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.
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 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.
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.
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.
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.
Book Reviews: Otherworldly skies, real and imagined
Today I'm reviewing -- and recommending -- two art-laden books. Michael Carroll's Drifting on Alien Winds is nonfiction, while the IAAA's The Beauty of Space is an art book, but both books are about describing our understanding of the alien-yet-familiar worlds across our solar system, and what they'd look like if we could stand on them.
Have two spacecraft ever docked to two separate space stations on the same day?
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.
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.
Scale solar system presentation slide, version 2
Last month I posted a preliminary version of a slide I was working on for use in my public presentations, a slide that contains everything in the solar system bigger than 400 kilometers across, and invited comment. I've listened to all of your comments and corrections and come up with a second version.
