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...

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 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...

Thruster burn kicks off crucial series of manoeuvres
Today kicks off a crucial series of Rosetta thruster burns designed to bring the spacecraft to the comet on 6 August. The first burn is set to take place at 17:30 UTC (19:30 CEST).
