NASA has delayed the launch of shuttle Endeavour so technicians can check its wiring to avoid problems similar to those plaguing Columbia, officials said Thursday.
Endeavour was supposed to blast off Sept. 16 but will not be launched earlier than October so technicians can remove radar equipment and check the shuttle's wiring.
NASA officials said they were not sure whether Endeavour would fly before Discovery, scheduled for a Hubble telescope repair mission in mid-October.
Last month, a damaged wire in Columbia's cargo bay caused a short circuit just five seconds into the launch. The short knocked out the primary computers for two of the three main engines.
