Comet Probe Finds Elements of Life
.png "Comet 67P-C-G (400 px)")
The Rosetta spacecraft has discovered all the elements of life in the gases jetting from a comet as it approaches the Sun.
The ingredients that make up amino acids, life’s building blocks, are all contained in the tail of the comet 67P/Churyumov-Gerasimenko (67P/C-G). Among them are methane, methanol, CO2, ammonia and water. All proteins are made of amino acids.
If Rosetta’s lander, Philae, discovers complete amino acids when it reaches the comet’s surface in November, it would support the hypothesis that life on Earth was seeded by comets with complex organic molecules as well as water. . . .

Rosetta Spacecraft's Planned Orbit Around Comet | VIDEO
By European Space Agency (ESA)
1-10-14
Rosetta's journey from launch in March 2004 to comet 67P/Churyumov-Gerasimenko in August 2014, including 3 flybys of Earth and 1 of Mars. By January 2014 Rosetta is about 9 million kilometres from comet 67P/CG.
By early May, Rosetta will be 2 million kilometres from the comet and at the end of May the spacecraft will execute a major rendezvous manoeuvre to line it up for orbit insertion at the start of August. . . .
