PASADENA, CALIFORNIA, JAN 27: The Jet Propulsion Laboratory here announced late on Wednesday that a parabolic antenna at Stanford University had picked up a signal that may have come from the lost Mars Polar Lander. NASA now plans to make a new attempt to contacting its Mars space probe, which has been incommunicado since it was lost near Mars two months ago.The new attempt to contact MPL will take place this week, despite an announcement by NASA that it considered the probe lost. ``This week's test is a long-shot, and I wouldn't want to get anyone excited about it,'' said Richard Cook, MPL's project manager, who had said no more attempts would be made to recover the spacecraft. However, the Jet Propulsion Laboratory, which is responsible for the probe, said the test was to be carried out because the antenna had picked up a signal that was ``definitely'' artificial and may have come from MPL.
