On the last day of her incredible mission, Rosetta slowly descends to the surface of Comet 67P/Churyumov-Gerasimenko. After having sent her extraordinary data back home, she is ready to join Philae for a well deserved rest on the comet. But is there one last surprise in store?
The ExoMars programme will investigate the Martian environment and demonstrate new technologies paving the way for a future Mars sample return mission in the 2020's.
Rosetta has made the most detailed study of a comet ever. It followed Comet 67P on its journey through the inner Solar System, measuring the increase in activity as the icy surface is warmed up by the Sun. Philae, a small lander, was released onto the surface in November 2014. Rosetta followed to the comet surface on 30 September 2016.
A global space astrometry mission, Gaia is making the largest, most precise three-dimensional map of our Galaxy by surveying more than a thousand million stars.
