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.
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.
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!
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.
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.
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.
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.
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.
Science from Vesta at the Geological Society of America meeting
I'm nearly two weeks late getting to this news but better late than never, right? There was a press briefing from the Dawn mission at the Geological Society of America (GSA) meeting on October 12.
Pretty pictures & movies: Eye candy from two recent Cassini Enceladus flybys
Cassini has completed two very close flybys of Enceladus in less than three weeks, one of them just this morning, and the images from that encounter have already arrived on Earth.
Eris and embargoes (or: don't fear Ingelfinger!)
Last Tuesday at the Division of Planetary Sciences meeting Bruno Sicardy presented the results of his research group's observations of a stellar occultation by Eris.
Lovely pic of a recent crater on Vesta
With little fanfare, the Dawn mission continues releasing a new picture from Vesta every day. This one is definitely my favorite among their recent releases, a closeup on one of Vesta's strange streaky bright craters.
Saturnlit moon, sunlit fountains
It's been a week of very heavy science on this blog, so I thought it'd be nice to go into the weekend with a post in which a breathtaking picture speaks for itself, without needing my thousands of words.
Notes from Day 5 of the EPSC/DPS meeting: Saturn's storm, Phobos, and Lutetia
Today was (is) the last day of the Division of Planetary Sciences / European Planetary Science Congress meeting in Nantes, France.
Notes from Day 3 of the EPSC/DPS meeting (all about MESSENGER)
Today I largely spent in the MESSENGER sessions. They have a lot of data to talk about.
Russia's Venera-D mission (DPS-EPSC 2011)
During the afternoon poster session at the Division of Planetary Sciences / European Planetary Science Congress meeting, I had a long talk with Ludmila Zasova (IKI) about Russia's Venera-D mission to Venus.
Brief notes from Day 2 of the DPS-EPSC meeting
It's been a very full day at the DPS-EPSC 2011 joint meeting. My day was less full than it might have been, because I overslept and missed most of the morning's session. I really needed the rest though so I think it was probably for the best!
Some first impressions of EPSC-DPS meeting
Today they turned on the scientific fire hose at the Division of Planetary Sciences / European Planetary Science Congress meeting happening here in Nantes, France. My brain already feels full and I still have four more days!
