Discovery

The official EPSC-DPS press-release about our latest discovery on the analysis of the moons of (93) Minerva and understanding of the composition of this main-belt triple system is finally out. Two years ago, I reported on this blog the discovery of those moons. Let's confess that I am glad to have finally solved secrets of this enigmatical main-belt asteroid. It was one of the most difficult multiple systems to characterize and understand due to its strangely spherical shape. Hopefully it will give birth to follow-up works... read more ❯

Kepler-16 is another great discovery coming from the Kepler telescope, the 10th NASA Discovery mission which is devoted to finding Earth-size exoplanets by monitoring variations of brightness due to transit. Today the Kepler team found a circumbinary exoplanet, an exoplanet orbiting a binary star system. Did they find Tatooine? In the large 105 deg2 field of view of the Kepler spacecraft, ~156,000 stars are being almost continuously observed by the 0.95m telescope. In 2010, the star number KIC... read more ❯

Today NASA announced three future key missions preselected as part of the Discovery program named GEMS, TiME and Comet Hopper. This is an important announcement, which was anxiously eagerly expected by our community. The NASA Discovery program is a low-cost mission ($425 million FY2010) program aimed at developing and support well-defined and narrow-range science mission in the field of planetary exploration. Discovery is a dynamic and highly valuable program which had led to a lot of well-known missions with a wide range of scientific goals including (adapted from Visions & Voyages Decadal survey): - NEAR Showmaker (Feb 1996) to rendezvous the Near... read more ❯
