It might seem a bit paradoxical to drive a HUMMER for 1,200 miles across the thin ice of the Northwest Passage with the goal of investigating climate change in the arctic circle, but that’s exactly what a crew from the
Mars Institute is planning to do. The team will be charting the thickness of the ice as it moves at about 12 miles per hour over the surface, but the information gathered during the trek will really just be a bonus. The team’s first priority will be to see how the HUMMER-based rover fares in these harsh conditions. At some point, the Mars Institute hopes that this data will prove useful in helping NASA design human-toting vehicles that will be able to traverse the surface of Mars.
The
Scientific American reports : 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. (Above

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.

Remember when those two satellites collidedthe other day? Seems that they’ll be thespace junk gift that keeps on giving, as their 800-km debris orbiting field could hamper allfuture space launches.
“Future launches will have to be adjusted with regard to the fact that the debris [from the collision] has spread over an 800-km area and will gather at a common orbit in 5-6 years,” said Alexander Stepanov, director of the Pulkovo Observatory in St. Petersburg.
