In typical Florida summer fashion, we are experiencing a thunder and lightning storm cell moving overhead from west to east, delaying the 7:32 pm launch of Falcon 9.

New launch time is targeted for SpaceX tonight at 9:15 p.m. ET for a Falcon 9 launch of 22 Starlink satellites to low-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Base in Florida.
If needed, there are two additional launch opportunities tonight at 10:06 p.m. ET and 10:56 p.m. ET .
Up to four backup opportunities are also available on Sunday, July 23 starting at 7:09 p.m. ET (23:09 UTC) until 10:31 p.m. ET (2:31 UTC on July 24).
