Rosetta wake-up media briefing at ESOC - Part 1

Replay of Part 1 of the Rosetta wake-up media briefing at the ESA Operations Centre ESOC, in Darmstadt, Germany, on 20 January 2014.

Highlights include a welcome address from ESA's Thomas Reiter, Director of Human Spaceflight and Operations, reports from inside ESA's Main Control Room and presentations from Alvaro Gimenez, ESA Director of Science and Robotic Exploration and Johann-Dietrich W?rner, Chair of the German Aerospace Centre and Chair of ESA Council.

Rosetta was launched in 2004 and has since travelled around the Sun five times, picking up energy from Earth and Mars to line it up with its final destination: comet 67P/Churyumov--Gerasimenko. For the coldest, loneliest leg of the mission, as Rosetta travelled out towards the orbit of Jupiter, the spacecraft was put into deep-space hibernation.

In 2014, Rosetta will complete its cruise towards the comet, rendezvousing with it in August, before putting its Philae lander onto the comet's surface in November, as it begins its journey closer to the Sun.

The spacecraft's internal alarm clock is set for 10:00 GMT (11:00 CET) on 20 January. Once it has warmed itself up, it should re-establish communication with Earth several hours later.

Rosetta: When can we see the comet?

Visualisation of how comet 67P/Churyumov-Gerasimenko will appear in Rosetta's OSIRIS narrow angle camera between May and August 2014. During this time, the 4 kilometre-wide comet will grow in size in Rosetta's field of view from an apparent diameter of less than 1 camera pixel to well over 1000 pixels -- equivalent to a resolution of better than a few metres per pixel -- allowing the large surface features to be resolved.

The comet featured in this animation is an artist's impression. It is shown to scale, but the shape and surface details are only representative. In addition, the real comet will be rotating during Rosetta's approach. The planets are not to scale.

Rosetta puts on the brakes

Rosetta is about to put on the brakes to ensure that it is on target for comet 67P/Churyumov-Gerasimenko.

This video explains the crucial orbit correction manoeuvres that are required to slow down Rosetta's speed, relative to the comet, from 750 metres per second to just one metre per second between 21 May and 5 August. By then, nine thruster burns (including one test burn in early May) will have reduced the distance between them from one million kms to just under 200 kms.

We also see the first images of the comet from the spacecraft's OSIRIS camera (Optical, Spectroscopic and Infrared Remote Imaging System), taken between 24 March and 4 May 2014. As the spacecraft gets closer to the comet, further images will improve the orbital corrections and provide more details about the comet's shape, size and rotation.

MIRO, built by an international team for the European Space Agency, will start taking measurements from late May onwards and will measure gases released from the comet as it approaches the Sun.

Main Rosetta burn

Published on 13 Jun, 2014

Rosetta is now closing its target: comet 67P/Churyumov--Gerasimenko and key manoeuvres have been done recently to slow down the spacecraft with the objective to have Rosetta orbiting the comet early August. Rosetta has successfully completed the first of three main thruster burns. Two further main burns in June (4 and 18), and six smaller burns between now and August, are ensuring that the spacecraft is on target for comet 67P/Churyumov-Gerasimenko. The first burn took place 500 million kilometres away on 21 May, used 218 kilogrammes of fuel and lasted 7 hours and 16 minutes -- one of the longest thruster burns in ESA's history. This video shows members of the mission team monitoring the burn in real time at the Rosetta control room at the European Space Operations Centre at Darmstadt in Germany. It also includes the role of the spacecraft's ALICE instrument and how the Rosetta Plasma Consortium, a set of five instruments, is preparing for the release of the Philae lander onto the comet's surface.

How big is Rosetta compared with the comet?

This short animation explains the relative sizes of the Rosetta spacecraft and comet 67P/Churyumov--Gerasimenko.

Rosetta is 32 m from tip to tip of the solar wings. Assuming the comet measures about 4 km across, that's 125 times the width of Rosetta.

Unlike typical artist's impressions, this image is scaled to convey the vast difference in size between Rosetta and the comet, even when the spacecraft is in a close 10 km orbit, as depicted here.

Rosetta arrives at the comet at an altitude of 100 km in the first week of August, and will move progressively closer over the following two months, with the intention to orbit at an altitude of just 10 km, depending on the comet's activity. For Philae's deployment in November, Rosetta will come to within a few kilometres of the surface.

The comet depicted in this animation is an artist's impression.

The Rosetta mission is now on a race against time to prepare maps and collect data before the Philae lander is due to be sent down to the surface of comet 67P in November. In this edition of Euronews Space, the 'Comet Hunters' show us how to orbit a comet, how Rosetta 'sees' its target, and what the mission means to the world of science, and to this team in particular.
