Rosetta carried out its final manoeuvre last night at 20:50 GMT (22:50 CEST), setting it on a collision course with the comet from an altitude of about 19 km. Rosetta had targeted a region on the small lobe of Comet 67P/ChuryumovGerasimenko, close to a region of active pits in the Maat region.

Rosetta and the UK

With funding from the UK Space Agency, Rosetta was a mission with significant UK involvement. UK scientists are involved in ten of the 21 experiments that Rosetta carried out during its mission:

  • the Open University lead the team for the Ptolemy instrument on the lander
  • Armagh Observatory are helping to analyse the results from the OSIRIS instrument
  • Imperial College London and University College Londons Mullard Space Science Laboratory (MSSL) supply the team studying the comets plasma
  • scientists at Oxford University are part of the science team for VIRTIS
  • Queen Mary College at the University of London will be investigating the results of the CONSERT instrumentIndustry involvement

The following UK companies have been involved in the mission:

  • Airbus Defence and Space, based in Stevenage, was the major subcontractor for the Rosetta platform
  • the Science & Technology Facilities Council (STFC) Rutherford Appleton Laboratory managed to reduce a lab full of chemistry equipment to enable it to fit into a space the size of a shoebox
  • SciSys UK Ltd was responsible for the spacecraft Mission Control System development and maintenance; in recognition of this work on the Rosetta and the Beagle 2 missions, SciSys were awarded the title of Innovator of the Year by the UK Computing Awards for Excellence 2004
  • VEGA Group plc was involved in many aspects of the Rosetta mission, from the overall design of the spacecraft to the on board software technology created by Logica (now CGI) helped to explore some of the issues involved in such a long mission, the company was also involved in the development of the Rosetta on board software
  • AEA Battery Systems Limited provided innovative batteries for the spacecraft and lander. These are smaller, lighter and much more reliable than the traditional nickel-cadmium batteries
  • AEA Technology, European Space Tribology Laboratory (ESTL) developed the Micro-Imaging Dust Analysis System (MIDAS)
  • Polyflex Space Ltd provided tanks to store the helium used by the lander
  • Surrey Satellite Technology Limited (SSTL) designed a wheel that stabilised the probe as it descended and landed on the comet
