Brief Philae "Morning After" update: First ÇIVA panorama from the surface

Posted by Emily Lakdawalla on 2014/11/13 04:53 CST | 1 comment

I'm just getting up to speed on the news from overnight, which is mostly good: Philae remained in contact with the orbiter (which means the CONSERT radar sounding experiment was working), and it's sitting stably on the surface, although it's not anchored in any way. And they released the first ÇIVA image from the ground!

PHILAE HAS LANDED! [UPDATED]

Posted by Emily Lakdawalla on 2014/11/12 10:21 CST | 16 comments

The landing happened on time just after 16:02 UT today! Philae mission manager Stephan Ulamec said: "Philae is talking to us! The first thing he told us was the harpoons have been fired and rewound. We are sitting on the surface." Those words later turned out not to be true; but we do know at least that Philae survived the landing and is returning good data.

Philae update: First of four "go-no-go" decisions is a GO!

Posted by Emily Lakdawalla on 2014/11/11 01:21 CST | 3 comments

It's been a day of calm before the storm here at the European Space Operations Centre in Darmstadt, as we get ready for the big event tomorrow: Philae's hoped-for landing on a comet. The first of four "go-no-go" decisions has been made, and it's a "go."

I'm reporting live from the press room at the European Space Operations Centre in Darmstadt, Germany. There's little news on Philae yet except that its status is good.
