A SpaceX Falcon 9 Block 5 carrying 54 Starlink satellites has finally launched at 8:18 PM EDT on Sunday, Sept. 18 (00:18 UTC on Sept. 19) after unfavorable weather scrubbed attempts on Tuesday, Wednesday, Thursday, and Friday. A Saturday launch opportunity was also called off.
This mission launched from Space Launch Complex 40 (SLC-40) at the Cape Canaveral Space Force Station in Florida. The booster supporting Starlink Group 4-34 is B1067, which had flown on five previous missions. B1067 debuted on the CRS-22 mission and went on to launch the Crew-3, Turksat-5B, Crew-4, and CRS-25 flights.
