SpaceX to Launch Second Batch of Cellular Starlink Satellites Tonight

The launch window opens at 7:31 pm PT and comes after the FCC recently cleared SpaceX to expand testing of its upcoming cellular Starlink system.

Following successful tests, SpaceX is preparing to bolster its cellular Starlink system by launching a second batch of “direct to cell” Starlink satellites later today.

The six satellites are slated to fly into orbit on a Falcon 9 rocket, which will also carry 15 other Starlink satellites. "Liftoff is targeted for 7:31 pm PT, with backup opportunities available until 11:25 pm PT. If needed," SpaceX said on its website

The launch comes after SpaceX secured FCC approval to test the cellular Starlink system in more locations in the US, including statewide in California, Washington, Texas, and Hawaii.

The technology promises to let unmodified smartphones receive internet connectivity in cellular dead zones, often found in rural and remote areas. SpaceX is aiming to launch the service for T-Mobile customers later this year, first to enable text messages, before rolling out voice and data support. But to do so, it’ll first need to secure full FCC approval to operate the service commercially, rather than for just testing purposes. 

The company launched the first batch of six direct-to-cell satellites in January. Since then, SpaceX’s tests have shown the satellites can successfully beam internet to smartphones with speeds up to 17Mbps. The service can also reach phones under tree cover or based indoors.   

SpaceX will live stream the launch on Twitter/X. If weather conditions force a delay, then the company could push liftoff to Saturday at a launch window that starts at 7:25 p.m. PT.

In an earlier FCC filing, SpaceX said it plans on operating as many as 840 direct-to-cell satellites over the next few months. But it looks like the company has slowed the launch cadence, possibly to work on finalizing designs for the direct-to-cell satellites.
