Planetary Society Hangout: March 7th, 2013 - What's Going On With Curiosity and a NASA Budget Update
Thursday at noon PST/3pm EST/20:00 UT
Thursday at noon PST/3pm EST/20:00 UT we check in with Emily Lakdawalla to bring us up to speed with Curiosity's computer problems and we check in on NASA's budget status.

The second in a series of audio blogs chronicling my trip to the driest spot on Earth, Chile's Atacama desert, to see the inauguration of the ALMA Observatory. Al Wootten and Alison Peck tell the story of ALMA.
February 25, 2013--The Longest Journey Begins With a Single Dose
The first in a series of audio blogs chronicling my trip to the driest spot on Earth, Chile's Atacama desert, to see the inauguration of the ALMA Observatory.
A frequently-asked question last week was: if asteroid 2012 DA14 is coming so close to Earth, why hasn't anyone taken any pictures of it? Now that 2012 DA14 has whizzed past us, we do finally have some radar pictures of it, but they still may not satisfy everyone.
The Astronomy Budget Squeeze
It's not just NASA. All of space science feels the pinch of smaller budgets.
It's not just the Planetary Sciences division within NASA that's under harsh budgetary times. The NSF Division of Astronomical Sciences is facing a choice between funding scientists and funding telescopes. A report from the 221st AAS meeting in Long Beach.
Near-Earth asteroid 4179 Toutatis will be passing within 7 million kilometers of Earth on December 12. Both radio telescopes and the Chang'E 2 spacecraft will be acquiring images.

I was inspired by my recent trip to Goldstone to put together this poster showing all three of the great 70-meter dishes of the Deep Space Network. There's one at each of the three complexes, at Goldstone, at Robledo (near Madrid, Spain), and at Tidbinbilla (near Canberra, Australia).

Last week JPL released two animations of asteroid 2005 YU55 made from the radar data acquired by Goldstone's 70-meter radio dish.

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!

A terrific set of Goldstone radar images of a good-sized near-Earth asteroids named 2010 JL33 was posted to the JPL website yesterday. They also posted a movie version but something about these pixelated radar image series absolutely begs for them to be displayed as an old-school animated GIF, so I made one.

Radio scientist Lance Benner posted to the Minor Planets Mailing list this evening the following message: "We have detected STRONG radar echoes from 2010 AL30 at Goldstone."

New observations reported this week in the journal Nature have cast doubt on the theory that thick deposits of ground ice lie conveniently close to the surface in permanently shadowed crater floors at the lunar poles.

Recent radar observations of Saturn’s moon Titan have produced the first direct evidence that the second largest moon in the solar system may be hiding pools of liquid hydrocarbons underneath its smoggy atmosphere.
