Lander manager says Philae is doing well but battery life is low

One method to discover planets beyond the solar system by far is transit photometry, which measures changes in a star’s brightness when a planet crosses in front of its star along our line of sight. NASA’s Kepler Space Telescope has used this technique to become the most successful planet-hunting spacecraft to date, with more than a thousand established discoveries. Satellites carrying improved technology for all-sky surveys are now planned, missions that will tell us a great deal about alien planetary systems similar to our own.

The European Space Agency’s first foray into science fiction, in the form of a short film entitled Ambition that promotes the Rosetta mission, may herald a new way in which science outreach can be conducted.

Researchers have used data collected by the Cassini spacecraft to build a computer simulation of Saturn’s icy ocean moon Enceladus that includes the thickness of the ice crust. At its south poles, huge geysers of water jet into space. These come from the ocean depths and suggest that the ice there must be relatively thin for this to happen.
