The historic landing of ESA's Rosetta Philae lander on comet 67P/Churyumov-Gerasimenko on November 12, 2014, has been hailed as a major milestone in the exploration of our Solar System.

Learn about Rosetta, Philae, and the most recent results by attending the following two SETI Talks in December:

Rosetta: Wild Bounce at comet Churyumov-Gerasimenko - Claudia Alexander, December 9, 2014 at noon.

Claudia AlexanderRosetta is the third cornerstone mission of the European Space Agency's (ESA) Horizon 2000 Programme. It's goals are to examine some of the original material of the Solar System with a comprehensive evaluation of the minearologic, isotopic, and organic constituents of a comet; understand how the body works as a machine to absorb and re-radiate energy from the sun; and understand more about the origins of the Solar System.

In this talk, I'll explain the science background of some of the mysteries of comets, including pros and cons about why we think comets might have brought Earth's water, concepts regarding missing nitrogen in the outer Solar System, and material the comet is made of (CAIs & IDPs). The talk will include early images of the comet's activity. I'll set the stage for the landing and walk through the 60 hours of time spent on the comet's surface. Finally I'll present an overview of initial findings.

The Rosetta Lander (PHILAE) mission: landing on comet 67P/Churyumov-Gerasimenko - Jens Biele (DLR), December 16, 2014, at 7:00 pm.

Jens BieleThe Rosetta Lander, Philae, has landed on 67P/Churyumov Gerasimenko on November 12, 2014. Until then, a landing site had to be selected within just 2 months, based on data from the Rosetta Orbiter instruments and analyses on flight dynamics and illumination profiles. Philae was programmed to perform a First Scientific Sequence immediately following touch down, and then enter its long term science mode.

The paper will report on the actual landing and the very first results. The landing was successful, though the operational sequences had to be modified ad hoc:  Philae did not anchor upon first touchdown at 15:34:06 UTC but rebounded at least once, finally settling - fully operating all the while - at a place not ideal for long-term science. A wealth of science data has been received. 

Rosetta is an ESA mission with contributions from its member states and NASA. Rosetta's Philae lander is provided by a consortium led by DLR, MPS, CNES and ASI.
