Long, long ago men and women on Earth gazed in wonder at comets that appeared in the sky. What where these mysterious objects? Rosetta and Philae learn about the history of comets from their grandfather, Giotto.


...there was a spacecraft called Rosetta. Rosetta had been travelling in space for 10 years, towards a comet called 67P/Churyumov-Gerasimenko. Before long, Rosetta was able to see the comet in the distance, and she took stunning pictures as she got closer and closer. There was only a little way to go now...


 Rosetta’s journey from launch in March 2004 to comet 67P/Churyumov-Gerasimenko in August 2014, including 3 flybys of Earth and 1 of Mars. By January 2014 Rosetta is about 9 million kilometres from comet 67P/CG. By early May, Rosetta will be 2 million kilometres from the comet and at the end of May the spacecraft will execute a major rendezvous manoeuvre to line it up for orbit insertion at the start of August.


 After a ten year journey through space, ESA’s Rosetta spacecraft will reach comet 67P/Churyumov-Gerasimenko in August 2014. After catching up with the comet Rosetta will slightly overtake and enter orbit from the ‘front’ of the comet as both the spacecraft and 67P/CG move along their orbits around the Sun. Rosetta will carry out a complex series of manoeuvres to reduce the separation between the spacecraft and comet from around 100 km to 25-30 km. From this close orbit, detailed mapping will allow scientists to determine the landing site for the mission’s Philae lander. Immediately prior to the deployment of Philae in November, Rosetta will come to within just 2.5 km of the comet’s nucleus.


This animation is not to scale; Rosetta’s solar arrays span 32 m, and the comet is approximately 4 km wide.
