NASA announced on Friday that they’re very close to deciding how they’ll fix the tiny cracks discovered in fuel lines of the entire space shuttle fleet. If the plan is approved, workers could begin welding the cracks as early as next week. Although the cracks apparently formed quite a while ago, NASA engineers are concerned that bits of metal could break off from the fuel lines and cause catastrophic damage to the shuttle’s engines. If all goes well, the first shuttle could launch as early as September 26.
