Our lander’s asleep

With its batteries depleted and not enough sunlight available to recharge, Philae has fallen into ‘idle mode’ for a potentially long silence. In this mode, all instruments and most systems on board are shut down. “Prior to...

Lander battery voltage falling fast

On board Philae, system voltage has fallen very close to 21.5V; below that, the battery won’t last much longer. At this time, there is insufficient sunlight to provide power.

Philae still talking!

Rosetta has regained contact with Philae sitting on the surface of a comet (511 million km away!) during tonight’s communication pass, confirming that the lander still has power on the surface of Comet 67P/Churyumov-Gerasimenko. The pass began...

Turning Philae

Update from ESA’s Main Control Room: as mentioned in today’s ESAHangout, ground controllers are planning to issue a ‘turn command’ to Philae later this evening. The aim will be to rotate Philae’s main body in the hopes...

Philae’s first touchdown seen by Rosetta

Philae touched down for the first time almost precisely where intended, a strong testament to the precision of the flight dynamics teams who planned Philae's journey down to comet 67P/C-G.


REPLAY – Rosetta & Philae mission update 14 ...

Watch the reply from today's ESA Hangout: Rosetta and Philae teams from ESA, DLR and CNES provide an update on mission status. OSIRIS PI Holger Sierks reports on images, and NASA scientists join from JPL.

Media briefing 14:00 CET start

Next media briefing on the Philae comet landing will start at 14:00 CET today, at ESA’s Operations Centre, Darmstadt, Germany. Watch the media briefing live via webcast.

ESA rolls out the big iron

For landing operations this week, ESA is once again rolling out the 'big iron' - two of the Agency's three ultra-sensitive 35m deep-space tracking stations, these ones located at Malargüe, Argentina, and New Norcia, Australia.
