Critical ground support equipment needed to prepare NASA’s Mars 2020 rover for its journey to the Red Planet has arrived at a payload processing facility at the Kennedy Space Center in Florida. The rover is being manufactured at the agency’s Jet Propulsion Laboratory in California and, once complete, will be sent to Kennedy for assembly, prelaunch processing and checkouts.
Forty years ago, a Voyager spacecraft snapped the first closeup images of Europa, one of Jupiter’s 79 moons. These revealed brownish cracks slicing the moon’s icy surface, which give Europa the look of a veiny eyeball. Missions to the outer solar system in the decades since have amassed enough additional information about Europa to make it a high-priority target of investigation in NASA’s search for life.
What makes this moon so alluring is the possibility that it may possess all of the ingredients necessary for life. Scientists have evidence that one of these ingredients, liquid water, is present under the icy surface and may sometimes erupt into space in huge geysers. But no one has been able to confirm the presence of water in these plumes by directly measuring the water molecule itself
