Editor note: NASA held a teleconference today with Wayne Hale with regard to repairs needed for STS-122. According to Wayne Hale "We have no launch date to talk about today".
Hale said that NASA would attempt to do all required repairs to Atlantis' External Tank on the launch pad. Hale expressed confidence that the repairs could be done in this fashion. However, if that is not possible, then a roll back to the VAB might be needed.
