NASA Shifts Lunar Orbiter To EELV; May Drop Probe Into Crater

NASA may try to drop a sensor into a permanently dark crater at one of the Moon's poles as early as 2008 to probe for water ice in the super-cold shade there. The idea is one option for using extra payload capacity gained from a decision to launch the planned Lunar Reconnaissance Orbiter (LRO) on an Evolved Expendable Launch Vehicle (EELV) instead of a smaller Delta II. Also under study is the launch of one or more small communications/navigation satellites to support future lunar exploration missions. Scott Horowitz, associate administrator for exploration systems, dropped the Delta II to avoid stability problems with its spinning second stage, growing out of the heavy fuel load needed to get to the Moon. He will decide as early as this month between the larger Atlas V or Delta IV EELVs for the LRO launch. Either way, the LRO mission will gain at least 1,000 kg. (2,204 lb.) in capacity for a piggyback mission. Under the lander idea, some sort of small, inexpensive spacecraft would be sent into one of the polar craters where data from previous orbiters have suggested there may be water ice. Another proposal under study would send at least one microsat into lunar orbit to provide communications links and navigation services for subsequent surface explorers. Exploration managers also are surveying the NASA science directorate for potential add-on payloads.
