Phoenix Space Probe to Explore for Life on Mars
The Phoenix is scheduled to work for three to four months in temperatures that will range between -27 and -99 degrees Fahrenheit. Among its duties, the Phoenix will dig up samples of the permafrost and analyze them for signs of life. "The Phoenix mission not only studies the northern permafrost region, but takes the next step in Mars exploration by determining whether this region, which may encompass as much as 25 percent of the Martian surface, is habitable," said Peter Smith, Phoenix principal investigator at the University of Arizona. Smith continued, "The climate change for our planet is written into the ices in the Arctic region on the Earth...the Arctic regions are where the history of life, microbes, molecules and cells are preserved in their purest form."
The Mars landing is a risky one, because only about 50% of our previous probes, which began in 1970, have proved successful.
This is likely to renew the debate about funding future NASA projects.
Questions:
In light of the failure rate, should we be spending the $420 billion for this project?
Should our entire space program be put on hold until we are on better financial footing?
Are we spending too much on our space program? Too little?
Should we concentrate solely on unmanned probes or should we go for more manned missions?
Will the Phoenix find signs of life?
