The detection of biosignatures on Mars is of outstanding interest in the current field of Astrobiology and drives various fields of research, ranging from new sample collection strategies to the development of more sensitive detection techniques. Detailed analysis of the organic content in Mars analog materials collected from extreme...

The comet rendezvous mission Rosetta will be the first mission to encounter and land on a comet nucleus. After a 10-year journey Rosetta is set for rendezvous with Comet 67P/Churyumov-Gerasimenko in summer 2014. The mission goal is: to study the origin of comets; the relationship between cometary and interstellar material and its implications...

The evolved gas analyzer COmetary SAmplingand Composition experiment (COSAC) aboardthe Philae Lander of ESA's Rosetta mission was designedto make unique in situ chemical analyses ofnucleus material from comet 67P/Churyumov-Gerasimenko, with an emphasis on organic molecules.Twenty-five minutes after Philae's initial touchdown,the COSAC mass...

Comets harbor the most pristine material in our solar system in the form of ice, dust, silicates, and refractory organic material with some interstellar heritage. The evolved gas analyzer Cometary Sampling and Composition (COSAC) experiment aboard Rosetta's Philae lander was designed for in situ analysis of organic molecules on comet...
