TITUSVILLE, FL – A spectacular SpaceX Jellyfish formed high in the skies over the Space Coast soon after the launch of another batch of Starlink broadband internet satellites just before sunrise on Thursday, May 21.
Liftoff of the SpaceX Falcon 9 on the Starlink 10-31 mission took place at 6:04 a.m. ET (1004 UTC) on May 21 from Space Launch Complex-40 on Cape Canaveral Space Force Station, FL.

A dramatic looking ‘jellyfish’ can form when sunlight reflects off the massive exhaust plume as the Falcon 9 rocket rises into high altitude daylight from initial ground darkness – usually within an hour of sunrise (in this case) or sunset during the ascent to orbit.

Some eight and a half minutes after liftoff, F9 B1077 successfully landed upright on the ‘A Shortfall of Gravitas’ or ASOG droneship – prepositioned about 400 miles downrange off the coast of the Carolinas

The first stage booster B1077.28 supporting this mission, previously launched Crew-5, GPS III Space Vehicle 06, Inmarsat I6-F2, CRS-28, Intelsat G-37, NG-20, TD7, and now 21 Starlink missions.
Overall this counts as the 150th landing on ASOG and marks the 613th booster landing to date.

It should return to Port Canaveral atop ASOG in 2 to 3 days.

TITUSVILLE, FL – On July 23, I was interviewed live on FOX 13 Tampa Bay about the 2nd attempt to launch the 13th SpaceX Starship test flight from Starbase, Texas shortly before the then planned liftoff on July 23. Bad weather intervened and SpaceX then rescheduled the liftoff to July 24 The first attempt to launch Starship 13th test flight
