Endeavour's Hydrogen Leak Fixed

摘要

Nasa will try to launch the Space Shuttle Endeavour July 11, nearly a month after a vexing hydrogen gas leak forced the U.S. space agency to scrub two countdowns in a row.rnWith repairs made, Endeavour successfully passed a leak check during a July 1 fueling exercise at Kennedy Space Center, Fla., setting the stage for a planned 7:39 p.m. EDT liftoff toward the international space station July 11, Mike Moses, who leads the shuttle's mission management team, said.
