MOSCOW. July 13 (Interfax-AVN) - The launch of the space shuttle Endeavor to the International Space Station (ISS) has been postponed for 24 hours due to unfavorable weather conditions over the Cape Canaveral launch pad in Florida.
A new attempt to launch the shuttle will be made at 2:51 a.m. Moscow time on Tuesday, NASA said on its website.
The spacecraft's initially planned launch on June 13 was cancelled when a leak of hydrogen gas from its fuel tanks was discovered. The launch was postponed until June 17, but the space shuttle did not lift off on that day because specialists needed more time to deal with the problem.
Thunderstorms forced NASA to call off Sunday evening's launch of the shuttle Endeavour.
The shuttle ISS mission has a crew of seven: commander Mark Polansky, pilot Douglas Hurley, mission specialists Christopher Cassidy, Thomas Marshburn, David Wolf and Canadian Space Agency astronaut Julie Payette.
Endeavour crew member U.S. astronaut Timothy Kopra will replace Japan's Koichi Wakata as an ISS crew member.
