The planned launch of a SpaceX Falcon 9 rocket Wednesday morning from Vandenberg Air Base could result in one or more sonic booms in the area, officials said.

The launch window will open at 7:17 am Wednesday, according to officials at the base outside Lompoc. The window will close at 7:30, according to SpaceX.

The rocket will carry a trio of terrestrial imagery satellites dubbed RADARSAT Constellation for the Canadian Space Agency, the agency said. The satellites are intended to provide data for maritime surveillance, ecosystem and climate change monitoring, and contingency planning for natural disasters, according to the mission's website.

The first reusable step of the The two-stage Falcon 9 rocket will return to Vandenberg after launch. It is during this attempt to land that the inhabitants of the counties of Santa Barbara, San Luis Obispo and Ventura could hear one or more sonic booms, according to officials of the base.

The satellites will begin to be deployed about 54 minutes after launch, according to SpaceX.

If the launch is cleaned on Wednesday, the launch window for the backup will be from 7:17 to 7:30 Thursday, according to SpaceX.

Satellites will allow daily review of Canadian territory and its maritime approaches, including the Arctic, up to four times a day, according to SpaceX. The company says that they will:

  • Help create accurate ice charts to make navigating the oceans and Great Lakes easier.
  • Improve detection and tracking of vessels of interest.
  • Help farmers maximize yields while reducing energy use and the use of potential pollutants.
  • Support relief efforts by providing images of areas affected by disasters.

Originally launched by Atlas in 1962, SpaceX's Space Launch Complex 4E in Vandenberg was used until its last launch of Titan IV in 2005. As of July 2011, SpaceX began to undergo major modifications and reconstructions. , completed 17 months later.

In recent years, SpaceX and other Vandenberg rocket launchers have created colorful screens at dawn or dusk, flooding social media with photos and videos. It would be the third time since Vandenberg.

On January 11, a SpaceX Falcon 9 orbited the last ten satellites of the Iridium constellation, and a secret government launch, the Delta IV IV, was launched on January 19 by the United Launch Alliance.

Minuteman 3 missile tests have recently been launched at Vandenberg, including one on May 1st and another on May 9th.

The next announced launch from Vandenberg will take place in early 2020, when a SpaceX Falcon 9 rocket will launch a satellite for the Argentine space agency, according to The satellite is supposed to provide radar images to facilitate emergency response and monitor the environment.
