Klim Churyumov (1937-2016)

We were saddened to learn the news yesterday that Klim Churyumov, who discovered Rosetta's comet together with Svetlana Gerasimenko in 1969, has passed away. Many of us had the pleasure to meet him at various Rosetta Mission events held...


CometWatch from Kepler

During the last month of Rosetta's operations at Comet 67P/Churyumov-Gerasimenko, it was no longer possible to observe the comet with telescopes on Earth because it was not far from the Sun's position in the sky and therefore...


Rosetta’s Earth ‘twin’ switched off

Just as the real Rosetta spacecraft ended its mission on the comet a week ago today, so this week Rosetta's 'twin', an engineering qualification model here on Earth, was also switched off. The replica Rosetta had been...

Rosetta impact site named Sais

In case you missed it during our live coverage on Friday, Rosetta's impact site has been named Sais. Mission Manager Patrick Martin announced the name of the impact site after contact with the comet's surface was confirmed and...


Alice’s last spectra

We were happy to spot this tweet from Rosetta's Alice instrument Principal Investigator Alan Stern over the weekend, showing the final spectrograph image obtained by the instrument moments before Rosetta impacted on to the surface of the comet on Friday: Heading...


Mission Complete

Mission complete: Rosetta’s journey ends in daring descent to comet ESA’s historic Rosetta mission has concluded as planned, with the controlled impact onto the comet it had been investigating for more than two years. Read the press...

Loss of signal confirmation

Spacecraft Operations Manager Sylvain Lodiot confirms loss of signal (LOS) and end of Rosetta operations at 13:19 CEST, 30 September 2016, via the voice loop in the Main Control Room at ESA's space operations centre, Darmstadt, Germany.

Comet landing: Rosetta’s last image

UPDATED CAPTION INFO This is Rosetta's last image of Comet 67P/Churyumov-Gerasimenko, taken shortly before impact, an estimated 20 m above the surface. The initially reported 51 m was based on the predicted impact time. Now that this has...

Last call from Rosetta

Going... going... gone! A sequence of screenshots showing the signal from Rosetta seen at ESA's ESOC mission control centre via NASA's 70m tracking station at Madrid during comet landing on 30 September 2016. The peak of the...


Comet landing descent image – 1.2 km

Rosetta’s descent continues. Here's an OSIRIS narrow-angle camera Comet 67P/Churyumov-Gerasimenko captured at 10:14 GMT from an altitude of about 1.2 km on 30 September. The image scale is about 2.3 cm/pixel and the image measures about 33...


Rosetta’s landing site

Here's a sequence of images captured by Rosetta's OSIRIS narrow-angle camera during its descent to the surface of Comet 67P/Churyumov-Gerasimenko on 30 September. The last images in the first and second row (on the right) are published...


Comet landing descent image – 5.7 km

Another striking image of the Ma'at region of Comet 67P/Churyumov-Gerasimenko from Rosetta's descent onto the surface of the comet, taken with the OSIRIS narrow-angle camera at 08:21 GMT from an altitude of about 5.7 km. The image...


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!

Throughout the entire Rosetta mission, the Flight Dynamics team at ESOC have been some of the hardest-working, behind-the-scenes wizards ensuring navigation – and today is no exception. They also have some of the coolest visualization tools in...


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...
