Icy surprises at Rosetta’s comet

This article is mirrored from the main ESA Web Portal. Rosetta’s comet approached its most active period last year, the spacecraft spotted carbon dioxide ice – never before seen on a comet – followed by the emergence...


Space Science Image of the Week: NAVCAM close-ups

A trio of the closest NAVCAM images of Comet 67P-Churyumov Gerasimenko is featured as our ESA Space Science Image of the Week. During the last few weeks of its mission at Comet 67P/C–G, the Rosetta spacecraft ventured closer...

An encounter with Klim Churyumov

Two years ago this week, the entire world was getting ready for a historic endeavour in space: the first soft landing of a human-made probe on a comet. On 12 November 2014, Rosetta's lander Philae landed on...


Rosetta Legacy winner announced

Between 6 September and 7 October 2016, we collected 235 contributions to the Rosetta Legacy tumblr. A huge and sincere thank you to all participants who shared experiences, stories and images of how the mission of Rosetta...

Rosetta’s deep-space ringtone

One of the responsibilities of the engineers on any mission's Flight Control Team is to monitor the spacecraft and react immediately in case of trouble.


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...

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...
