Three space launches could be on tap this weekend - CBS News

Delays earlier this week have set up a weekend of rapid-fire Florida launches, weather permitting, starting with a United Launch Alliance Delta 4 Heavy flight Saturday and possibly two SpaceX flights Sunday just nine hours apart that would mark the company's 100th and 101st orbital missions.If SpaceX presses ahead and both rockets get off — and the weather is not ideal — it would mark the shortest span between two U.S. orbit-class missions since 1966.But ULA has priority with plans to launch a powerful Delta 4 Heavy, one of just five left in the company's inventory, early Saturday to boost a National Reconnaissance Office spy satellite into orbit.With forecasters predicting an 80 percent chance of good weather, liftoff from pad 37 at the Cape Canaveral Air Force Station is targeted for 2:04 a.m. EDT Saturday.ULA originally planned to launch the national security mission Wednesday, clearing the way for SpaceX to launch a previously flown Falcon 9 rocket from nearby complex 40 on Friday evening to place Argentina's SAOCOM 1B remote-sensing satellite into a polar orbit.The California rocket builder then planned to launch the company's 12th batch of Starlink internet relay satellites from pad 39A at the Kennedy Space Center Saturday morning.
