CAPE CANAVERAL, Fla. -- Shuttle Endeavour could finally climb into space Sunday.
After three delays due to hydrogen leaks and lightning strikes, NASA says the spaceship is in good shape. And the astronauts are getting ready to go blast off for the international space station.
Engineers did not find any lightning damage from Friday's storm. And last month's repairs apparently worked, because there was no repeat Sunday of earlier hydrogen gas leaks.
NASA test director Steve Payne says the shuttle is "rock solid." The weather forecast has improved to 70% "go." And liftoff is set for 7:13 p.m. Eastern Time.
Five spacewalks are planned during the 16-day mission to deliver and install the last piece of a Japanese lab on the space station.
