SPACE reports that “SpaceX called off the much-anticipated second launch of its massive Falcon Heavy rocket on Wednesday (April 10) due to unacceptable wind conditions in the upper atmosphere.” In a Twitter post, SpaceX representatives said, “Standing down from today’s Falcon Heavy launch attempt; next opportunity is tomorrow, April 11.” The rescheduled Thursday launch “would occur at 6:35 p.m. EDT (2235 GMT), with weather forecasts currently predicting a 90% chance of good weather, according to the 45th Weather Squadron at Cape Canaveral Air Force Station.” Less than one hour before SpaceX announced the postponement, SpaceX CEO Elon Musk said, “Upper atmospheric wind shear is very high. ... Will have to postpone launch unless weather proves soon.” (Image Credit: Associated Press–©)
