Pres. Obama's budget proposal for fiscal year 2010 throws White House support behind two of the more controversial NASA plans of the Bush era: retiring the space shuttle in 2010 and returning humans to the moon by 2020.
The shuttle's scheduled phaseout, part of Pres. Bush's 2004 Vision for Space Exploration, is opposed by thousands of people who work at Cape Canaveral or in jobs tied to the shuttle missions as well as lawmakers such as Republican Sen. Kay Bailey Hutchison of Texas, who don't want the U.S. to rely on Russia for transport to and from the International Space Station. As currently planned, the U.S. will not ready a replacement manned transport system before 2015.
But many in the space community, including the nonprofit Planetary Society, have encouraged NASA to hold fast to the 2010 retirement, citing the orbiter's spotty safety record, outmoded technology and limited reach—shuttle flights can only reach low Earth orbit, leaving the moon, let alone Mars, well out of reach. (The Obama budget leaves the door open for an additional shuttle flight beyond the nine currently scheduled, "if it can safely and affordably be flown by the end of 2010.")
