Boeing and NASA officials have scrubbed today's launch attempt of NASA's Mars Exploration Rover-B "Opportunity" spacecraft aboard a Boeing [NYSE: BA]
Delta II rocket from Cape Canaveral Air Force Station, Fla.
The cause of the scrub was shifting winds aloft in the Cape area that affected the second launch window of 12:37:59 a.m. EDT today.
The first launch window of 11:56:16 p.m. EDT on June 28 was not utilized due to a combination of toxic wind concerns and mariner activity in the launch hazard area.
The next launch attempt will be today at 11:46:14 p.m. EDT. A second launch opportunity exists at 12:28:07 a.m. on Monday, June 30, if necessary.
