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....

Rosetta enroute to pre-delivery orbit

Today's burn put Rosetta on a very elliptical trajectory rapidly moving the spacecraft away from the 10-km orbit. On 31 October, the mission control team will perform another manoeuvre to enter onto the pre-delivery orbit.

Go for 10 km!

With the last week spent at about 20 km from 67P/C-G, the decision has now been made to go to just 10 km. A series of manoeuvres will reduce Rosetta’s distance from its current 18.6 km orbit...

The details on today’s orbit entry

Of the ten orbit correction manoeuvres (OCMs) that began on 7 May, there remains just one to complete: the last one is dubbed 'CATI' for 'Close Approach Trajectory – Insertion' and will take place today.

Half way through the burns!

Five down, five to go! We’re now half way through the rendezvous burn manoeuvres needed to put Rosetta on course with comet 67P/Churyumov-Gerasimenko, and tomorrow will check off the sixth. Tomorrow’s burn is also the second of...

The comet takes shape, one pixel at a time!

Rosetta’s scientific imaging system OSIRIS is slowly but surely resolving comet 67P/Churyumov-Gerasimenko in its narrow angle camera (NAC), giving the first tantalising hints of its shape. The comet covers about four pixels in this image, which was...

Rosetta smells its exhaust

Just in time to coincide with today’s orbit correction manoeuvre, we have a great blog update contributed by Kathrin Altwegg, from the ROSINA science team at the University of Bern. A spacecraft is made out of terrestrial...

Big Burn No. 3 update 19:09 CEST

Today’s orbit correction manoeuvre ended fine, with no issues. Completed as of 17:33 CEST on board (confirmation received ~17:54 CEST on ground). All OK with the mission!

Thrusters ON – update for 15:40 CEST

Photo taken about 55 mins ago in the Rosetta control room at ESOC as the temperatures of the four thrusters being used in today’s orbit correction manoeuvre started to rise, indicating the burn had started! Thruster temperatures...

The Big Burns Part 3

On Wednesday, 18 June, Rosetta will conduct the third in a series of three ‘Big Burns’, which are themselves part of the ten-burn series of orbit correction manoeuvres taking us to comet 67P/C-G.

The comet, which was discovered in 1969, has a diameter (nucleus) of four kilometres. Frame from 'Chasing A Comet – The Rosetta Mission' https://www.youtube.com/watch?v=5b7u6stKgfs Credit: DLR (CC-BY 3.0)

The Big Burns – Part 2

It's burn week in space again! Rosetta's next orbit correction manoeuvre – #BigBurn2 – is set for tomorrow, and is set to run for about 6hr:41mins and achieve a delta-v of 269.5 m/sec.

Rosetta’s first Big Burn complete

The Rosetta team reports that last night's orbit correction manoeuvre (OCM) – or thruster burn – was completed as planned, providing the first of three big orbital 'pushes' to get the spacecraft lined up for comet arrival...

The Big Burns – Part 1

Tomorrow, Rosetta will conduct a massive orbit correction manoeuvre (OCM) deep in our Solar System, switching on its thrusters for a bit less than 8 hours to reduce its speed relative to comet 67P by a whopping...
