VANCOUVER, British Columbia (Reuters) - Scientists preparing for the exploration of Mars are planning history’s first car drive through the fabled Northwest Passage, a trip they said on Friday will provide data on global warming and man’s potential impact on other planets.
The trip using a modified armored Humvee vehicle will provide comprehensive data about the thickness of winter ice in the waterway through Canada’s high Arctic, said Pascal Lee, chairman of Mars Institute and leader of the expedition.
The scientists also hope to learn more about what happens to the microbes left behind by humans as they explore remote areas, amid concerns from some scientists about the detrimental impact of such journeys in space.
“It’s not just about protecting men from Mars. It’s also about protecting Mars from men,” Lee said in an interview.
Long sought as a faster route between the Atlantic and Pacific oceans, the Northwest Passage was first traversed by ship in 1906 by Norwegian explorer Roald Amundsen, a trip that took three years to complete.
Failed attempts to travel the passage include that of Sir John Franklin, who with his crew of 128 died in 1845 after becoming stuck in the ice.
This 1,000-mile trip, if successful, would mark the first time a land vehicle crossed the passage, the researchers said a Vancouver news conference.
Environmental scientists warn that global warming has been melting summer ice in the Northwest Passage, and channel was opened though it briefly in 2007 and 2008, the first time that had happened in modern memory.
Scientists now estimate the ice thickness using satellites, so the land journey will improve the information they have and provide a base of data against which future changes can be judged, Lee said
The melting has destroyed much of the older ice that would have been too jagged to travel over even a decade ago, but if it continues for another decade it may not be thick enough to travel on at all.
“We’re taking advantage of a window of opportunity,” Lee said.
The scientists will still be watching out for areas that are too thin to drive over, and will be accompanied by two snow mobiles in case of an accident.
The drive is expected to take two to four weeks to make, and the scientists hope to start in early April although they can wait last late as mid-May if needed.
The Mars Institute is already active in the region, using a facility on Devon Island in Canada’s high Arctic to test vehicles that might eventually be used to explore the surface of Mars or the moon.
