Impact time update: 10:38 UT

Based on the Navigation Camera images taken shortly after last night’s collision manoeuvre, flight dynamics analysis has refined the predicted time of Rosetta’s impact into the Ma’at region on the small lobe of Comet 67P/C-G to 10:38:32 UT+/- 2 minutes at the...

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....

Earlier today…!

Rosetta’s OSIRIS wide-angle camera captured this image at 11:49 GMT on 29 September 2016, when the spacecraft was 22.9 km from Comet 67P/Churyumov–Gerasimenko.   Credits: ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA

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...

The cometary zoo

The ROSINA instrument on Rosetta has been “sniffing” the environment of Comet 67P/Churyumov-Gerasimenko for the past couple of years, obtaining unprecedented measurements of the gases found in a comet’s atmosphere. Besides the main component – water vapour...

A comet’s life – a new sonification of RPC data

In 2014, shortly after Rosetta’s arrival at Comet 67P/Churyumov-Gerasimenko, the magnetometer on the Rosetta Plasma Consortium (RPC) suite of instruments, RPC-Mag, detected some surprising oscillations in the plasma surrounding the nucleus, revealing the comet’s mysterious “song”. Now,...

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...

Beneath the surface of Comet 67P

While scientists and the public alike have been astounded by the unexpected shape of Comet 67P/ Churyumov-Gerasimenko’s nucleus, what lies beneath the surface is just as important scientifically. Comet interiors preserve a unique record from the formation...

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...

How Rosetta gets passivated

Since Rosetta wasn't designed to have its transmitter permanently off, we had to change the on-board software by patching it.

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...

Real life trumps animation

An ‘insider tale’ from the Flight Control team, who are already reminiscing about their favourite moments from Rosetta’s epic journey.

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...
