ROSINA confirms pressure increase

As Rosetta approaches the surface of Comet 67P/Churyumov-Gerasimenko, the Comet Pressure Sensor (COPS) on the ROSINA instrument is measuring the gas pressure around the nucleus increasing!

Comet landing descent image – 5.8 km

As Rosetta continues its descent onto the Ma’at region on the small lobe of Comet 67P/Churyumov-Gerasimenko, the OSIRIS narrow-angle camera captured this image at 08:18 GMT from an altitude of about 5.8 km. The image shows dust-covered terrains,...

Comet landing descent image – 8.9 km

As Rosetta gets closer and closer to Comet 67P/Churyumov-Gerasimenko, the OSIRIS narrow-angle camera captured this beautifully detailed image of the comet surface at 06:53 GMT from an altitude of about 8.9 km. The image shows a portion of...

Comet landing descent image – 11.7 km

During Rosetta’s final descent, which is currently undergoing, the OSIRIS narrow-angle camera captured this image of Comet 67P/Churyumov-Gerasimenko at 05:25 GMT from an altitude of about 11.7 km. With dramatic shadows, the image shows the comet’s ‘neck’...

Impact site is coming in to view!

We just received this image from the OSIRIS wide-angle camera, taken at 02:17 UT at the comet. It shows the target impact region just coming in to view in the lower left –look for the distinctive shape of...

Descent images begin!

We’ve started to get images from Rosetta’s descent. This one was taken by the OSIRIS narrow-angle camera at 01:20 UT, from a distance of around 16 km. The image scale is about 30 cm/pixel and the image...

Collision manoeuvre complete

Rosetta has completed its final manoeuvre and is now on a collision course with Comet 67P/C-G. A small thruster burn starting  20:48:11 UTC and lasting 208 seconds has set the craft on course towards its final destination....

Rosetta Legacy Highlights

Over the past two years, the Rosetta mission has captured the imagination of many people worldwide, stimulating them to produce art and music, and to undertake other creative activities with friends and families – some even made...

Comet Landscapes and maps of the southern hemisphere

During today’s science briefing at ESA’s ESOC, Mohamed El-Maarry (University of Bern) presented a series of highlights about the landscape of Comet 67P/Churyumov-Gerasimenko. Here are some highlights from his presentation. Over the past two years, Rosetta mapped...

Science highlights briefing starting soon

The Rosetta science highlight briefing at the European Space Operations Centre (ESOC) in Darmstadt, Germany, will start shortly. Tune in from 14:30 14:45 to the livestream viewer at rosetta.esa.int or via https://livestream.com/ESA/rosettagrandfinale or ESA’s Facebook page to follow...

#LivingWithAComet blog post series – summary

Find out from Rosetta’s instrument teams what it was really like “living with a comet” for two years. The blog posts include anecdotes from the teams including challenges overcome and ‘scares’ the instruments gave them, as well as...

Living with a comet: an OSIRIS team perspective

 OSIRIS, Rosetta’s Optical, Spectroscopic and Infrared Remote Imaging System, has been our all-seeing eye on Comet 67P/Churyumov-Gerasimenko, capturing nearly 68,000 high-resolution images of its nucleus and coma from all angles for 924 days. Here the OSIRIS team...

Living with a comet: RPC team perspective

RPC, the Rosetta Plasma Consortium, comprises five sensors tasked with investigating the magnetic, electric and plasma environment of Comet 67P/Churyumov-Gerasimneko – the most well-known results perhaps being that of the “Singing Comet” and the non-magnetised nature of...

Living with a comet: an Alice team perspective

Rosetta’s ‘Alice’ instrument – which is the only Rosetta instrument that isn’t an acronym, it is simply a name that the instrument’s principal investigator, Alan Stern, likes – was the first in a line of ultraviolet spectrographs...

Living with a comet: a CONSERT team perspective

Rosetta and Philae were both equipped with the CONSERT radar experiment in order to bounce radio waves between the two to study the internal structure of the comet. Little did we know that this instrument would play...

Science ‘til the very end

Rosetta will collect science data until the very end of its descent on Friday. The opportunity to study a comet at such close proximity makes the descent phase one of the most exciting of the entire mission....
