SpaceX's Falcon Heavy rocket just got another passenger.
The powerful Falcon Heavy is now scheduled to loft Astranis' first commercial communications satellite to orbit next spring, Astranis representatives announced Thursday (Sept. 23).
The satellite — which will beam internet service down to Alaskans from geostationary orbit, about 22,200 miles (35,730 kilometers) up — had previously been slated to ride atop a SpaceX Falcon 9.
"Launching on Falcon Heavy will get us on orbit months faster, allowing us to serve customers in Alaska that much sooner," Astranis CEO John Gedmark said in a statement. "This is a huge win for our customers in Alaska."
The Alaska-serving satellite will be just the beginning for Astranis, if all goes according to plan.
"By owning and operating its satellites and offering them to customers as a turnkey solution, Astranis is able to provide bandwidth-as-a-service and unlock previously unreachable markets," representatives of the San Francisco-based company wrote in the same statement. "This allows Astranis to launch small, dedicated satellites for small and medium-sized countries, Fortune 500 companies, existing satellite operators and other customers."
The 880-pound (400 kilograms) Astranis satellite will share space on the Falcon Heavy with another communications craft — Viasat-3, which will be operated by fellow California company Viasat.
Falcon Heavy has just three launches under its belt to date, but it's poised to get quite a workout over the coming months. The rocket is scheduled to launch two classified missions for the U.S. Space Force by early 2022, the first of which will lift off next month. The Viasat-3/Astranis flight will follow shortly thereafter. And Falcon Heavy's manifest also includes NASA's Psyche asteroid mission, which is slated to launch next August.
The Falcon Heavy consists of three modified, strapped-together Falcon 9 first stages. The central core is topped by a second stage, which carries the payload. Like the workhorse Falcon 9, the Falcon Heavy is partially reusable; all three first stages are designed to return to Earth, make vertical, powered landings, and fly again.
