Rosetta’s complete journey – animation

Now in one complete animation: Rosetta’s trajectory around Comet 67P/Churyumov–Gerasimenko, from arrival to mission end. The animation begins on 31 July 2014, during Rosetta’s final approach to the comet after its ten-year journey through space. The spacecraft...

Impressions of Rosetta’s legacy: an e-book

In September–October 2016, over 200 people contributed to the Rosetta Legacy campaign, sharing stories, images, videos, creations and experiences to convey what the mission had meant to them. We decided to collect all contributions in an e-book,...

OSIRIS Data Release: March–May 2015

A new batch of thousands of images from Rosetta’s OSIRIS imaging system have been released into ESA’s Archive Image Browser and the Planetary Science Archive. This latest OSIRIS data release comprises 2423 narrow-angle camera images and 4378...

Reflections

Some ten weeks have passed since Rosetta ended its mission on the surface of Comet 67P/Churyumov–Gerasimenko, and it is time for a little reflection here on the Rosetta blog… Over the past three years, we have written...

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...

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...

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...

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!
