Mars Exploration Endangered by Bureaucratic (In)Action
The road to Mars just seems to get longer and harder every day. The Planetary Society has just asked its Members to contact the White House and ask John Holdren, the President's Science Advisor, to make sure that NASA and ESA are allowed to work together on the 2016 and 2018 missions to Mars.
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!
Awards for Planetary Society figures at the 2011 Division of Planetary Sciences / European Planetary Science Congress meeting
I arrived in Nantes just in time to see two major figures in the Planetary Society win big awards.
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!
Off to France! DPS-EPSC 2011 (a big planetary meeting)
I'm leaving shortly for Nantes, France to attend the 2011 joint meeting of the Division of Planetary Sciences (DPS) of the American Astronomical Society and the European Planetary Science Congress (EPSC). You may be saying, wait, why is the American Astronomical Society having a meeting in France?
China's first space station takes flight
A Long March rocket carried China's first space station, Tiangong-1, into orbit September 29.
Mars Exploration Rovers Update: Opportunity Digs In at Endeavour Crater, Team Remembers 9/11
Since leaving the plains of Meridiani, pulling up to Endeavour Crater and checking out its first rock last month, Mars Exploration Rover Opportunity has wasted no time in getting the
What's up in the solar system in October 2011
Without a doubt the most exciting events in space in October are Cassini's two, count them, two extremely close flybys of Enceladus, spaced only eighteen days apart, on October 1 and 19 (and followed by a third one on November 6).
Dawn Journal: Fourth year in space, and arrival in HAMO
Dawn's fourth anniversary of being in space is very different from its previous ones. Indeed, those days all were devoted to reaching the distant destination the ship is now exploring. Celebrating its anniversary of leaving Earth, Dawn is in orbit around a kindred terrestrial-type world, the ancient protoplanet Vesta.
Pretty pictures: Dancing moons
Since Cassini currently orbits Saturn within the plane of Saturn's rings, it has lots of chances to catch two or more moons in the same photo. One such
Sagan and Snooki
This image has been making the rounds of Google+ and Facebook today.
Finally, an official statement on UARS' exact reentry time and location
The world watched on Friday as the derelict spacecraft named UARS made its final few orbits around Earth. And then we waited for final word of its reentry location. And waited. And waited.
MAVEN's baby picture
A new Mars mission, MAVEN, has finally leapt the hurdle separating its existence as an idea from its material existence. Here's MAVEN's baby picture: the just-completed
Readers: Help me identify "greatest hit" blog entries?
If you are reading this and happen to recall an entry that struck you as particularly educational or having a particularly beautiful picture or whatever, I'd very much appreciate it if you could note that in the comments (or by email or Twitter, if you prefer).
A Distant View of Triton
Ted Stryk reminisces on how he was turned on to astronomy.
The latest HiRISE view of Opportunity, on Endeavour's rim
In a now-routine act of obtaining detailed photographs of robots from Earth sitting on the surface of another planet, the HiRISE camera on Mars Reconnaissance Orbiter has captured a view of Opportunity sitting on the rim of Endeavour crater.
Tethys and Dione don't seem to be active after all
About four years ago I wrote a blog entry about an ESA press release about paper published in Nature that suggested that Saturn's moons Tethys and Dione might have volcanic activity, like Enceladus. A new paper published in Icarus casts doubt on that conclusion.
