The watery environment of early comets, together with the vast quantity of organics already discovered in comets, would have provided ideal conditions for primitive bacteria to grow and multiply.
Since the launch, the NASA operation and engineering team located at the NOAA Satellite Operation Facility have performed a series maneuvers designed to place the satellite in its proper orbit. They completed five liquid apogee motor burns designed to raise the GOES-O orbit perigee to approximately 22,300 miles above the Earth. GOES-O became GOES-14 once it reached its geosynchronous orbit at 89.5 degrees west longitude on July 8, 2009.
Professor Wickramasinghe said: "These calculations, which are more exhaustive than any done before, leaves little doubt that a large fraction of the 100 billion comets in our solar system did indeed have liquid interiors in the past.
So argue Professor Chandra Wickramasinghe and his colleagues at the Cardiff Centre for Astrobiology in a paper published in the International Journal of Astrobiology.
