. The upcoming mission, if it launches, is crucial to the future of American manned space flight. From the Washington Post article: "A successful flight will allow NASA to resume construction of the half-built International Space Station and possibly extend the life of the beloved Hubble Space Telescope, which has allowed humans to peer into far galaxies. But with the shuttle fleet due to retire in 2010, any serious problems during July's mission likely would bring a premature end to the shuttle program and disrupt NASA's plans to keep its skilled work force intact while a replacement spacecraft is being developed."
