Falcon 9 rocket successfully launches

Update 11:50 a.m. EDT June 5: The Falcon 9 rocket successfully launched as scheduled at 11:47 a.m. Monday.

Original report: SpaceX aims to launch its 28th commercial resupply services mission from the Kennedy Space Center at 11:47 a.m. The uncrewed Dragon spacecraft will deliver food, supplies and equipment, including two energy-producing solar arrays. It will also carry research and scientific experiments, among them an investigation into the ways plants adapt to environmental stress.

The launch window for SpaceX’s Falcon 9 rocket opens at 11:47 a.m. On Monday, SpaceX said weather conditions were “60% favorable for liftoff.”

The company earlier announced it will have a backup opportunity for liftoff at 11:01 a.m. on Wednesday.

SpaceX initially planned to launch its resupply mission on Saturday afternoon, though it delayed takeoff by one day to allow time for more preparations and for weather conditions to improve. The company planned to launch the rocket on Sunday until high winds prompted a second delay.

If the launch goes as planned on Monday, SpaceX’s Dragon spacecraft will dock on the International Space Station around 5:50 a.m. on Tuesday. It will spend about a month attached to the orbiting laboratory before returning to Earth with research and return cargo, according to NASA.

The Falcon 9 rocket is set to land on a drone ship in the Atlantic Ocean after stage separation, SpaceX officials said.
