HOP TO IT! 'DOWN UNDER' RESEARCH HELPS INTERNATIONAL MARS EFFORT
The links between the 'Red Planet' and the Red Centre are stronger than you might imagine, with a team of young Australians actively helping international research efforts aimed at sending human beings to Mars. Jennifer Laing talks to Guy Murphy, National Coordinator of the Australian Chapter of the Mars Society, about the work they are doing to develop prototype vehicles for testing in the outback.
SAVING Earth FROM OVERHEATING
A group of Astronomers have devised a plan to help protect the Earth from a scorched future - just move it further from the sun. Most Astronomers agree that the Sun is slowly heating up, so much that the Earth will be too hot for life within a billion years. This new plan to save the Earth involves passing a 100km asteroid near enough to the Earth that it imparts its orbital energy, and knocks our planet into a spiral orbit that keeps the Earth the right distance away from the Sun to maintain a habitable environment. Of course, one wrong move and a 100km asteroid smacks into the Earth and destroys all life anyway. Needless to say, we've got a few hundred million years to work out the finer points of the plan.
SHARK TEETH ON MARS
New pictures taken by the Mars Global Surveyor show beautiful shark teeth sand dunes at the edge of a larger field of dark sand dunes in Proctor Crater. The dunes are created by winds blowing from the East/Northeast, and then sunlight illuminates them from the upper left. These are some of the last images taken by Surveyor during its Primary Mission which ended January 31. Of course, Surveyor's Extended Mission has just begun.
