Mission
ViaSat-3 F3 (ViaSat-3 Asia-Pacific)
- Type: Communications
- Orbit: Geostationary Transfer Orbit
- Launch Cost: $90,000,000
The ViaSat-3 is a series of three Ka-band satellites is expected to provide vastly superior capabilities in terms of service speed and flexibility for a satellite platform. Each ViaSat-3 class satellite is expected to deliver more than 1-Terabit per second of network capacity, and to leverage high levels of flexibility to dynamically direct capacity to where customers are located.
Location
Launch Complex 39A
Kennedy Space Center, FL, USA
Find the best place to watch the launch from Florida
Launch Complex 39A has witnessed the launch of 221 rockets, including 220 orbital launch attempts. While Kennedy Space Center, FL, USA, has been the site for 280 rocket launches.
The John F. Kennedy Space Center, located on Merritt Island, Florida, is one of NASA's ten field centers. Since 1968, KSC has been NASA's primary launch center of American spaceflight, research, and technology. Launch operations for the Apollo, Skylab and Space Shuttle programs were carried out from Kennedy Space Center Launch Complex 39 and managed by KSC. Located on the east coast of Florida, KSC is adjacent to Cape Canaveral Space Force Station (CCSFS).
Rocket
SpaceX Falcon Heavy
The Falcon Heavy is a variant of the Falcon 9 full thrust launch vehicle and consists of a standard Falcon 9 rocket core, with two additional boosters derived from the Falcon 9 first stage.
Landing
Strap-On Booster B1072
The Falcon Heavy side booster B1072 will land back at the launch site at Landing Zone 40 after its 2nd flight. Booster B1072 last launched 06/25/2024 and has seen 1 successful launches and landings. Falcon Heavy side booster first flown during the GOES-U mission.
A sonic boom is likely to occur a few minutes after launch as the booster returns to the launch site. Be prepared for a loud but thrilling experience! Learn more about rocket launch sonic booms
Landing Zone 40 - LZ-40
Landing Pad at SLC-40 for Falcon 9 boosters. Built as an replacement for LZ-1 & LZ-2.
Return to Launch Site - RTLS
A return to launch site usually means that after stage separation the booster flips and does a burn back towards the launch site, landing near where it initially launched from.
Strap-On Booster B1075
The Falcon Heavy side booster B1075 will land back at the launch site at Landing Zone 2 after its 22nd flight. Booster B1075 last launched 10/22/2025 and has seen 21 successful launches and landings. Falcon 9 Block 5 booster first used for the Starlink Group 2-4 mission. Converted to a Falcon Heavy booster in 2026 after 21 launches.

Agency
SpaceX
Space Exploration Technologies Corp., known as SpaceX, is an American aerospace manufacturer and space transport services company headquartered in Hawthorne, California. It was founded in 2002 by entrepreneur Elon Musk with the goal of reducing space transportation costs and enabling the colonization of Mars. SpaceX operates from many pads, on the East Coast of the US they operate from SLC-40 at Cape Canaveral Space Force Station and historic LC-39A at Kennedy Space Center. They also operate from SLC-4E at Vandenberg Space Force Base, California, usually for polar launches. Another launch site is being developed at Boca Chica, Texas.
