On Friday, November 28 at 10:44 a.m. PT, Falcon 9 launched the Transporter-15 mission to sun-synchronous orbit from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California. 

On board this mission were 140 payloads, including cubesats, microsats, hosted payloads, and orbital transfer vehicles carrying 13 of those payloads to be deployed at a later time.

This was the 30th flight for the first stage booster supporting this mission which previously launched NROL-87, NROL-85, SARah-1, SWOT, Transporter-8, Transporter-9, NROL-146, Bandwagon-2, NROL-153, NROL-192, Transporter-14, and 18 Starlink missions. Following stage separation, the first stage landed on the Of Course I Still Love You droneship, which was stationed in the Pacific Ocean. 

There was the possibility that residents of and visitors to Santa Barbara, San Luis Obispo, and Ventura counties may hear one or more sonic booms during the launch, but what residents experienced depended on weather and other conditions.
