A second launch attempt was made on 17 June 2009 for which NASA moved the planned launch of the Lunar Reconnaissance Orbiter to a new date. On 17 June 2009 loading of the shuttle's external tank with liquid hydrogen and liquid oxygen was delayed three hours due to poor weather around the launch site, but tanking began once the weather cleared. Approximately two hours after tanking began, engineers saw leak indications in the GUCP similar to those seen during the first launch attempt. The launch was officially scrubbed at 01:55 EDT.
