Michael Meyer, the head of NASA's astrobiology programme, believes that it should at least delay a manned mission until Martian life was fully understood.
Actually seeing one created would put those deductions to the test.If the geology would be fascinating, the astrobiology would be even better.

Although Sagan did important research on planetary atmospheres, in astrobiology, and on the origin of life on Earth, he made his reputation primarily as a spokesman for science and a popularizer of astronomy.
Unlike exobiology, astrobiology respects the scientific possibility that life beyond Earth may never be found.
Astrobiology, a term coined for the study of all life anywhere in the universe (including Earth), has replaced exobiology, the study of extraterrestrial life exclusively and therefore criticizable as "a science that lacks a subject matter".
It was one of Nasa's most intriguing messages: an invitation to a briefing where it would "discuss an astrobiology finding that will impact the search for extraterrestrial life".
Professor Wickramasinghe said: "If the Rosetta orbiter has found evidence of life on the comet, it would be a fitting tribute to mark the centenary of the birth of Sir Fred Hoyle, one of the undisputable pioneers of astrobiology".
The $2.5 billion Curiosity project, Nasa's first astrobiology mission since the 1970s-era Viking probes to Mars, is the first to bring all the tools of a state-of-the-art geochemistry laboratory to the surface of a distant planet.
