"You can begin to see what LRO will look like in all of its glory," said LRO deputy project manager Cathy Peddie. The probe, slated to launch Nov. 24 aboard an unmanned Atlas 5 rocket from Cape Canaveral, Fla., is expected to spend between one and four years in lunar orbit collecting information. Finding usable sources of water, for example, will be critical in planning for an eventual base on the moon. "It costs tens of thousands of dollars per pound to put materials into space," said Timothy McClanahan with NASA's Goddard center. "That makes ordinary water on the moon more precious than gold. To make lunar exploration affordable, we need to use the resources of the moon as much as possible so we can avoid the cost of bringing them up from Earth." LRO will be carrying a second spacecraft for an independent mission that will land in a crater near the moon's south pole to look for evidence of water ice. The crater is permanently shadowed and very cold, conditions that scientists believe may have allowed water ice, delivered by comets long ago, to accumulate over billions of years. If water exists on the moon and it can be extracted, NASA could potentially convert it to liquid hydrogen and oxygen for rocket fuel and air for astronauts to breathe. Related Links: |
