QuoteU.S. Rep. Dave Weldon, a Republican whose Florida district includes the Kennedy Space Center, proposed extending the shuttles' lifetime to close the gap until their replacement ships, called Orion, are ready for their first manned flights in 2015. His proposal, which would cost about $10 billion, would have the shuttles make six or seven additional flights between 2010 and 2013 and speed up development of the Orion ships to be ready by then. A second proposal would keep the shuttles flying until 2015 and leave Orion's schedule alone. "This is an issue of priorities," said Weldon, who announced his plan at the Kennedy Space Center Visitors Center on Monday.
