Instrument commissioning continues

We’re now in week four of six dedicated to commissioning Rosetta’s science instruments after the long hibernation period, with the majority now having completed at least a first initial switch on. Many of the instruments have commissioning...

Replanning Europe’s mission of the decade: the ba...

Today’s blog post was contributed by Ruediger Jehn and his colleagues working on the Mission Analysis team at ESOC. These experts work behind the scenes on all of ESA’s interplanetary and observatory missions to map out –...

New mission ‘selfie’

Philae is well and truly awake: the lander's CIVA imaging system took these two images of Rosetta's solar arrays last night!

Cosima

COSIMA checked out and ready for collecting comet dust

COSIMA, the COmetary Secondary Ion Mass Analyser, will collect dust grains from comet 67P/Churyumov-Gerasimenko and analyse their chemistry. Martin Hilchenbach, Principal Investigator for COSIMA, introduces the instrument and describes some of the first commissioning activities. We are...

Here be dragons

What will comet 67P/Churyumov-Gerasimenko look like? The short answer is that we simply don’t know… but that wouldn’t make for a very interesting blog post, would it?! The “Here be dragons” title of this post refers to...

Checking out MIDAS

Software upgrade at 655 million kilometres

Mark Bentley, Principal Investigator for MIDAS, talks us through tonight’s activities to upgrade the instrument’s software.  Software upgrades are something we are all too familiar with – almost every day small fixes, or patches, are ready to...

Rosetta’s lander is awake!

Rosetta’s lander Philae was successfully reactivated today as part of the mission’s on-going instrument checkout phase. Unlike the orbiter, which had to wake up and establish contact with Earth autonomously based on a pre-set alarm clock, Philae...

Gotcha! Rosetta sets sights on comet

Rosetta has caught a first glimpse of its destination comet since waking up from deep-space hibernation. These two ‘first light’ images were taken on 20 and 21 March by the OSIRIS wide-angle camera and narrow-angle camera, as part...

Waking up MIDAS

We introduced you to Rosetta’s MIDAS instrument yesterday, ahead of today’s first switch on since hibernation. In this post, Principal Investigator for MIDAS, Mark Bentley, talks us through the sequence of events that are planned for today’s...

Payload commissioning underway

The re-commissioning of Rosetta’s science instruments is now in its second week, and while our operations and science teams are busy with those activities, we have a quick status report on the general health of the spacecraft...

Instrumental

Next week we take another step towards performing unique science at a comet: Rosetta’s instruments start to get put through their paces in what is known as the “payload commissioning” period of a mission. Of course, in...
