We’re probably still a bit short of packing our bags and heading to Mars. But it appears NASA’s Phoenix Mars Lander may have helped scientists figure out which parts of the planet are more habitable for humans than others. Recent (and controversial) evidence that certain portions of the Mars landscape could host liquid water has lent credence to the theory that the planet contains the ingredients necessary to support life as we know it, Space.com reports.
According to the article, four papers are
under review for scientific publication on four major discoveries from the
mission, said Peter Smith, the Phoenix mission’s principal investigator at the
University of Arizona in Tucson. Under discussion are the following factors for supporting life: “the presence of liquid water; the
presence of a biologically available energy source; and the presence of the
chemical building blocks of life in a biologically available for.” The report also named temperature and water activity as additional key requirements.
Interestingly, the (stationary) Phoenix Mars Lander may have plopped down a spot that’s perfect for life. “What you
see is that Phoenix comes down as a clear winner — a much, much higher
habitability index than any of the other sites,” Stoker told conference
attendees, according to the report. “The Phoenix landing site is the most habitable zone of any location
we have ever visited on Mars.”
