In the second half of a double header for spaceflight, SpaceX launched 23 more of its Starlink broadband satellites from California on Monday, March 11.

At 12:09 a.m. EDT on March 10 local time, a Falcon 9 rocket carrying the Starlink spacecraft took off from Vandenberg Space Force Base. (0409 GMT or 9:09 p.m. PDT).

It was the company’s second Starlink mission in little over four hours; from Florida’s Space Coast, 23 of the broadband boats had already been launched.

About 8.25 minutes after takeoff, assuming all goes according to plan, the first stage of the Falcon 9 will return to Earth and land vertically on the SpaceX droneship Of Course I Still Love You, which will be positioned in the Pacific Ocean.

As per the SpaceX mission description, this will be the booster’s 17th launch and landing. It has completed 16 missions thus far, 11 of which have been Starlink flights.

The upper stage of the Falcon 9 will keep moving into low Earth orbit (LEO), where the 23 Starlink satellites will eventually be launched approximately 62 minutes following launch.

SpaceX’s broadband megaconstellation, known as Starlink, provides internet access to users worldwide.

Currently, there are around 5,500 functioning Starlink spacecraft in low-Earth orbit (LEO), and this figure is expected to rise in the near future. In addition to the 12,000 Starlink satellites for which SpaceX now holds authorization, the company has submitted applications for an additional 30,000 or so.
