It should give you a feeling of déjà vu: a defunct satellite's orbit is decaying, and because that orbit is circular it's going to be impossible to predict where and when along its ground track it's going to happen.

The European Space Agency (ESA) seems to have gotten tired of waiting for NASA to commit to its share of the joint 2016/2018 Mars missions that were planned to lay the groundwork for an eventual delivery of samples of Mars to Earth.

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.

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.

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!

I arrived in Nantes just in time to see two major figures in the Planetary Society win big awards.

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!

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?
