DarkNemesis618 writes "NASA decided on Tuesday to delay the launch of Space Shuttle Discovery until July, squashing all hopes that it would launch in May. The external fuel tank is again the culprit, but this time it's not the foam. One of the four fuel sensors in the fuel tank that control when the space shuttle's main engines cut off was discovered to be faulty. This delay does however, give NASA the time it needs to decide what to do about the small crack found on the robotic arm. Over a week ago, a worker bumped the arm leaving a small crack in it. The arm is key to this next mission as the cameras and lasers used to inspect the shuttle for damage are mounted on the robotic arm. All things aside, NASA engineers are saying that the next possible launch date will be July 1st."
