Viasat's ambitious dream of a terabit-class broadband satellite is one step closer to reality! On November 13th, an Atlas 5 rocket, courtesy of United Launch Alliance (ULA), successfully launched Viasat's second ViaSat-3 satellite into orbit. This marks a significant milestone in Viasat's quest to revolutionize broadband internet, especially for those in need of high-speed connectivity.
The launch took place from Space Launch Complex 41 at Florida’s Cape Canaveral Space Force Station. The rocket released the ViaSat-3 F2 payload into a geosynchronous transfer orbit approximately three and a half hours after liftoff. Initial signal acquisition was confirmed shortly after, setting the stage for the satellite's journey to its final position at 79 degrees West over the Americas, which will take around three months.
This isn't just any satellite; it's a behemoth! Weighing in at six tons, it's one of the heaviest payloads ever sent up by an Atlas 5. When fully deployed, the satellite will be about the size of half a football field. But here's where it gets impressive: this single satellite is designed to provide more bandwidth capacity than Viasat's entire current fleet of 23 satellites combined!
The launch was originally scheduled a week earlier, but a faulty booster liquid oxygen tank vent valve caused a delay. The valve was promptly replaced, and the mission was back on track.
Now, let's rewind a bit. Viasat initially aimed to launch a 1 Tbps broadband spacecraft back in 2019. However, production issues, supply chain disruptions, and the COVID-19 pandemic pushed the first ViaSat-3 launch to 2023. Unfortunately, that first satellite, ViaSat-3 F1, suffered a major setback due to a failed antenna deployment, resulting in a loss of over 90% of its capacity.
This is a critical point: ULA was originally supposed to launch ViaSat-3 F2 in 2023. This was before the antenna issue with ViaSat-3 F1.
Mark Dankberg, Viasat's chairman and CEO, has stated that it should take a couple of weeks after ViaSat-3 F2 reaches its orbital slot to deploy and confirm that its reworked antenna is operating correctly. Because ViaSat-3 F2 shares similarities with the otherwise healthy ViaSat-3 F1, Viasat expects to move quickly through remaining health checks to start services early next year.
"It’s going to be a big boost to our network, especially to our mobility and fixed services,” Dankberg said, emphasizing the core value of the Viasat-3 series: its capacity and flexibility. For instance, in the in-flight connectivity market, a ViaSat-3 satellite is designed to provide a huge amount of bandwidth to a multitude of planes waiting at an airport and also follow them with a beam of connectivity as they fly to their destination.
“Some satellites have beam-forming to follow the plane around, but they’re doing that with 10, 20, 30 gigabits” of total capacity, he added. “ViaSat-3 can do that with close to a thousand gigabits.”
Boeing is contracted to provide a total of three ViaSat-3 satellites, with Viasat designing and building the payloads. The third satellite is slated to enter service over Asia in early to mid-2026, utilizing a deployable mesh antenna from L3Harris.
Looking ahead, Dankberg mentioned that the company is exploring ways to "miniaturize and package [ViaSat-3 technology] into much smaller satellites,” to leverage existing ground infrastructure and improve spacecraft manufacturing economics, with the goal of further reducing bandwidth costs.
