Liftoff of the Falcon 9 rocket is scheduled for 4:28 a.m. EDT from Complex 40 at Cape Canaveral Space Force Station.
The weather is expected to be nearly ideal for this 23rd Starlink mission, according to a Space Force forecast.
"Only scattered low-level clouds are expected as the moisture is only beginning to make its way back across the region," the forecast said.
There's no room for delays on a Starlink launch because the company targets a specific orbit. SpaceX already has launched 1,000 Starlink spacecraft as it sells ground-based receiver antennas and subscription service at $99 per month.
If delayed for technical issues or weather, the company has a backup plan to launch at 4:06 a.m. EDT Thursday.
The Falcon 9 first-stage rocket booster for the mission has be launched five times, including on three Starlink missions.
SpaceX will attempt to recover the booster again on a barge in the Atlantic Ocean. The company set a record March 14 by flying one booster for the ninth time.
