CONFLICT WITH 2011 LAUNCH OF JUNO PROMPTS NASA.

CONFLICT WITH 2011 LAUNCH OF JUNO PROMPTS NASA TO REWORK MSL PLAN. NASA's willingness to start the Jupiter-bound Juno spacecraft in August 2011 to strengthen the U.S. Space Agency consider switching to Mars Science Laboratory (MSL) Rover for an upgraded Atlas 5 rocket and put it to a more demanding course. Despite two months of the distance between the missions' planned launch of the Atlas 5 rocket lifted from Cape Canaveral Air Force Station, Juno and MSL is locked in a conflict the launch is expected to further increase the costs March Rover, sending a key element in over-budget spacecraft back to testing.

"The launch conflict with Juno we think is something that will take some time to implement, but I am convinced that we can find a solution," Richard Cook, MSL project manager at NASA's Jet propulsion laboratory, said in a January 9 meeting NASA Advisory Council's Planetary gear transmission science Subcommittee here. "It is certainly a price that we are working in the MSL replaner". NASA authorities announced in December that they had given up trying to end the MSL in time to make his long standing scheduled October 2009 launch window. Because the earth and March is in a favorable adjustment to launch every two years to lose this autumn window meant exposing the phone with $ 1.9 billion contract to 2011. The ideal 2011 launch window for MSL, but comes just two months after about 1 billion U.S. dollars Juno mission is scheduled to lift off from the same launch pad at Cape Canaveral. The two-month separation between launches will normally not pose a problem, but it does not need to live up to 90 days, the U.S. government's launch provider, Denver-based United Launch Alliance (UAA), which now requires the full integration of launching nuclear - powered spacecraft that MSL.

Nuclear-powered spacecraft has been shipped without power, so that extra work when the hardware on the launch site, "said Jim Green, director of NASA's Planetary gear transmission science division. At the request of NASA and U.S. Air Force, UAA has examined what it will take to shorten the processing time for land launches of nuclear-powered spacecraft from 90 days to 75, and for non-nuclear-powered spacecraft from 60 days to 45 UAA spokeswoman Julie Andrews said in January 22 that a decision is expected before the end of the month to implement the compressed open reading list for 2009.
