The Starlink flight, which will loft 60 new satellites for SpaceX’s growing megaconstellation from Cape Canaveral Air Force Station in Florida, will now lift off after the company’s planned Demo-2 mission on May 27.
“Standing down from the Starlink mission, due to tropical storm Arthur, until after launch of Crew Demo-2,” SpaceX wrote on Twitter today.
SpaceX’s Demo-2 mission is the company’s first crewed flight test of its Dragon capsule for NASA. The mission will launch two NASA astronauts to the International Space Station from Pad 39A of NASA’s Kennedy Space Center in Florida.
SpaceX originally planned to launch the upcoming Starlink mission on Sunday (May 17), but was forced to postpone the flight to Monday after another mission, the U.S. Space Force’s launch of an X-37B space plane, was also delayed by weather over the weekend.
SpaceX later announced that bad weather conditions from Arthur would push the launch back another to Tuesday, May 19. However, with surface winds expected to reach at least 39 mph (63 km/h), according to the National Hurricane Center, the launch has been pushed once again until sometime after May 27.

The company received criticism after the first Starlink launches because astronomers and other scientists cited that the brightness of the satellites, which launch in batches of 60, was interfering with observations.
SpaceX experimented with painting the satellites with a dark coating but, with this launch, intended to test a new approach, a “sunshade,” known as VisorSat, is a set of darkened shades that could deploy to block the sun. By eliminating the sun’s bright reflection, the satellites would, in theory, be much less bright and much less visible in the night sky.
In April, SpaceX founder Elon Musk announced that the company’s next launch, would test their new “sunshades,” known as the VisorSat, but they did not specify when that launch would be or if it would carry multiple VisorSats, according to SpaceNews. This upcoming launch will mark SpaceX’s eighth Starlink mission. Musk has said that all Starlink satellites would be equipped with sunshades by the ninth Starlink launch.
