August 6th, 2014 - Rosetta arrives at Comet

After travelling for 10 years around the Solar System since its launch in March 2004, ESAís Rosetta spacecraft has today finally caught up with with Comet 67P/Churyumov-Gerasimenko. Rosetta is the first spacecraft to undertake the long-term exploration of a comet at close quarters.

After entering orbit around Comet 67P/Churyumov-Gerasimenko, the spacecraft will release a small Lander in later this year onto the icy surface of the cometís nucleus. Rosetta intends to orbit the comet for about a year as it heads towards the Sun. Once it has passed its perihelion (the closest distance to the Sun), Rosetta will continue to orbit the comet for another half year.

Rosetta is one of the most challenging space missions ever - many of the complex navigation and landing manoeuvres need to take place automatically with absolutely no room for error. Instructions from the ground take up to 50 minutes to reach the spacecraft, so Rosetta must have the 'intelligence' to look after itself. It uses sophisticated on-board computers and software whose tasks include data management, attitude and orbit control.

CAPTEC worked for 4 years on the Rosetta project. It developed the Electronic Support System software for the Lander interface with the satellite and performed the ISVV (Independent Verification and Validation) of the Rosetta On-board Software. Its customer, EADS Astrium GmbH, is the Prime Contractor for this European Space Agency mission.

CAPTEC is currently working on the BepiColombo and Solar Orbiter missions and is looking for suitably qualified software/test engineers for satellite software and systems.
