Rosetta and Philae status update

Over the last few weeks, Rosetta has been flying along the terminator plane of Comet 67P/Churyumov-Gerasimenko, at distances from 180 km down to 153 km and at latitudes between 0 and 54 degrees, in order to find...

Video update from Lander Control Centre

As tweeted by the German Aerospace Center (DLR) yesterday, a mini status update direct from the Lander Control Center in Cologne. In short, the teams are still working hard on trying to re-establish contact with the lander. Update...

Rosetta and Philae: Searching for a good signal

After seven months in hibernation on the surface of Comet 67P/Churyumov-Gerasimenko, Rosetta’s lander Philae communicated with Earth via the orbiter on 13 June. Since then, seven periods of connection have been confirmed between the orbiter and lander,...

Philae wake-up triggers intense planning

The receipt of signals from Rosetta’s Philae lander on 13 June after 211 days of hibernation marked the start of intense activity. In coordination with its mission partners, ESA teams are working to juggle Rosetta’s flight plan...

Rosetta and Philae find comet not magnetised

This new result was just presented at EGU2015 and is published in Science Express today. The text is mirrored from our news story on the main ESA web portal.  Measurements made by Rosetta and Philae during the probe’s...

New trajectories for Rosetta

Rosetta continues to recover well from the problems experienced during the close flyby over the weekend of 28 March that resulted in the spacecraft entering safe mode. Some of the science instruments are now switched back on...

Rosetta status report: close flyby navigation issues

During its most recent close flyby last Saturday, where Rosetta flew within 14 km of the surface of the comet, the spacecraft experienced significant difficulties in navigation. This resulted in its high gain antenna starting to drift...

Rosetta Science Working Team meeting report

US Rosetta Project Scientist Claudia Alexander and ESA’s Rosetta Project Scientist Matt Taylor report on the discussions held at the recent Rosetta Science Working Team meeting. The Rosetta Science Working Team (SWT) met for the 40th time earlier this...

CometWatch 14 February – flyby special

On Saturday, Rosetta passed within just 6 km of the surface of Comet 67P/Churyumov-Gerasimenko in the first dedicated close flyby of the mission. The closest approach took place at 12:41 UT over the Imhotep region on the...

Where is Philae? When will it wake up?

These are the two most popular questions currently being asked of the mission – especially on our social media channels – and ones that we will try to answer in this post, including inputs from the OSIRIS...

Rosetta in 2015

On 4 February, Rosetta will start to move some 140 km from the comet, before swooping down to just 6 km from the surface on 14 February.

Status update – 11 November

It was a busy night for the Rosetta and Philae operations team, reported Rosetta flight director Andrea Accomazzo during this morning’s press briefing at ESA’s spacecraft operations centre (ESOC), who delivered the news that the lander Philae...

Green light for landing site J!

ESA has given the green light for its Rosetta mission to deliver its lander, Philae, to the primary site on 67P/Churyumov–Gerasimenko on 12 November.   The decision that the mission is ‘Go’ for...

Go for 10 km!

With the last week spent at about 20 km from 67P/C-G, the decision has now been made to go to just 10 km. A series of manoeuvres will reduce Rosetta’s distance from its current 18.6 km orbit...

CometWatch update

Regular followers of this blog will have noticed that we had a short pause in our routine “CometWatch” updates while we focused our outreach efforts on the landing site selection. NAVCAM images are of course still being...
