NASA officials revealed the space shuttle fleet will remain grounded until November at the earliest. Normally there was a launch scheduled for September but the space agency cancelled this one because they want to find a solution to prevent large pieces of foam debris being shed from the fuel tank.
The man leading Nasa's investigation admitted there were no obvious solutions to the problem, but he said modifications would have to be made.
"Frankly, even the next time we fly the tank, I would expect to see a little bit of foam loss somewhere in the tank," said Bill Gerstenmaier.
"I think it's an extremely difficult engineering problem to solve. There's no immediate answer or problem that jumps out at us."
