Live coverage: SpaceX to launch 28 Starlink satellites on Falcon 9 rocket from Cape Canaveral

SpaceX is aiming to launch its 900th Starlink satellite of the year, but faces some challenging weather during its launch window Saturday morning.

The Starlink 6-91 mission will add another 28 Starlink V2 Mini Optimized satellites to the constellation of more than 7,400 satellites currently in low Earth orbit. This will also be SpaceX’s 250th Falcon 9 rocket launch to date from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station.

Liftoff is targeted for Saturday, May 10, at 2:28 a.m. EDT (0628 UTC), with backup launch opportunities extending out to 6:21 a.m. EDT (1021 UTC) as long as fueling of the rocket hasn’t begun.

Spaceflight Now will have live coverage beginning about an hour prior to launch.

On Friday, the 45th Weather Squadron forecast a 55 percent chance of favorable weather during the launch window. Meteorologists expressed concerns with a series of storms pushing through Central Florida late Friday and heading into Saturday morning.

“Though most models are quiet in terms of showers and storms over the Spaceport by the start of the primary window early Saturday morning, the combination of jet-induced mid and high clouds mixed with anvils from any ongoing storms to the west will lead to a mixed threat for both Thick Cloud Layers and Anvil Clouds,” launch weather officers wrote.

SpaceX will use Falcon 9 first stage booster 1083 on this mission, which is flying for an 11th time. Its previous missions included Crew-8, Polaris Dawn, and Intuitive Machines’ second Nova-C lander.

A little more than eight minutes after liftoff, it aims to land on the droneship, ‘A Shortfall of Gravitas.’ If successful, this will be the 108th booster landing for this droneship and the 444th booster landing to date.
