UPDATE: SpaceX launches NASA mission from Vandenberg Space Force Base on Wednesday

WATCH: SpaceX set to launch NASA's TRACERS mission Wednesday at 11:13 a.m.

UPDATE (2:15 p.m.) - According to the FAA, the delay was due to a regional power outage in the Santa Barbara area that the agency reports "disrupted telecommunications at the Los Angeles Air Route Traffic Control Center, which manages air traffic over the Pacific Ocean. As a result, the FAA postponed the SpaceX Falcon 9 TRACERS launch on Tuesday, July 22. The FAA took this action to ensure the safety of the traveling public."

The outage also affected flights at airports in San Luis Obispo and Santa Barbara counties on Tuesday.

UPDATE (11:14 a.m.) - SpaceX's launch of the NASA TRACERS mission was scrubbed Tuesday, due to airspace concerns.

A hold was placed on the launch just 43 seconds before the rocket was scheduled to lift off, and officials announced they were standing down from the launch attempt.

SpaceX says it will try again on Wednesday with the launch window opening at 11:13 a.m.

SpaceX plans to launch a Falcon 9 rocket from Vandenberg Space Force Base on Tuesday, and area residents may hear a sonic boom.

The 57-minute launch window opens at 11:13 a.m.

WATCH:

About eight minutes after liftoff, SpaceX will aim to land the rocket’s first stage booster back on land at Vandenberg Space Force Base. This is likely to produce one or more sonic booms that people in Santa Barbara, San Luis Obispo and Ventura counties may be able to hear.

The rocket will be delivering a NASA payload called TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) into low-Earth orbit. The twin satellites will study how solar wind impacts the Earth’s magnetic field. According to NASA, this information will help scientists better understand and prepare for impacts to Earth, such as auroras and disruptions to telecommunications.

Several other satellites will also be along for the ride, including SEOPS’ Epic Athena, Skykraft’s Skykraft 4, Maverick Space Systems’ REAL, Tyvak’s LIDE, and York Space Systems’ Bard.

If Tuesday’s launch is scrubbed, SpaceX says it has a backup launch opportunity at the same time on Wednesday.
