The lander project manager Stephan Ulamec says tremendous science has been collected during Philae’s short time on the surface but battery life is now limited and it is unlikely to last much longer.

Rosetta’s comet 67P is much younger than previously thought
Based on computer simulations, astrophysicists at the University of Bern conclude that comet 67P/Churyumov–Gerasimenko did not obtain its duck-like form during the formation of our solar system 4.5 billion years ago. Although it does contain primordial material, they are able to show that the comet in its present form is hardly more than a billion years old.

The spider in the loop
This multicoloured swirl of yellow and blue shows a prominent ring of gas near the North Celestial Pole. The pole appears to be fixed in place, while the rest of the night sky slowly circles around it because of Earth’s rotation. This image comes courtesy of ESA’s Planck satellite, which spent years mapping the entire sky in exquisite detail between 2009 and 2013.

ExoMars spotted in space en route to Red Planet
On 14 March, the ExoMars spacecraft and Schiaparelli lander were lofted into orbit by a Proton rocket, starting a seven-month journey to the Red Planet. For the ExoMars launch, ESA’s near-Earth object (NEO) coordination centre in Italy organised a successful international campaign for ground-based optical observations of the departing spacecraft.
