Mission
Koreasat 6A
- Type: Communications
- Orbit: Geostationary Transfer Orbit
- Launch Cost: $52,000,000
The Koreasat 6A spacecraft, built by Thales Alenia Space, will have 20 transponders for fixed satellite services and six for TV broadcasting to replace the Koreasat 6 launched in 2010.
Koreasat 6A will be based on the manufacturer’s Spacebus 4000B2 platform and is expected to weigh about 3.5 metric tons at launch. It will be designed to operate for at least 15 years.
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 222 rockets, including 221 orbital launch attempts. While Kennedy Space Center, FL, USA, has been the site for 281 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 9 Block 5
Falcon 9 is a two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of satellites and the Dragon spacecraft into orbit. The Block 5 variant is the fifth major interval aimed at improving upon the ability for rapid reusability.
Landing
Core B1067
The Falcon 9 first stage B1067 has landed back at the launch site after its 23rd flight. Booster B1067 last launched 03/30/2026 and has seen 34 successful launches and landings. Falcon 9 Block 5 booster first used for the CRS-22 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 1 - LZ-1
LZ-1 Pad located at Cape Canaveral Space Force Station at the previous LC-13.
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.
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.
