Mission
WorldView Legion 3 & 4
- Type: Earth Science
- Orbit: Low Earth Orbit
- Launch Cost: $52,000,000
WorldView Legion is a constellation of Earth observation satellites built and operated by Maxar. Constellation is planned to consist of 6 satellites in both polar and mid-inclination orbits, providing 30 cm-class resolution.
Location
Space Launch Complex 40
Cape Canaveral SFS, FL, USA
Find the best place to watch the launch from Florida
Space Launch Complex 40 has witnessed the launch of 311 rockets, including 311 orbital launch attempts. While Cape Canaveral SFS, FL, USA, has been the site for 1027 rocket launches.
Cape Canaveral Space Force Station (CCSFS) is an installation of the United States Space Force's Space Launch Delta 45, located on Cape Canaveral in Brevard County, Florida.
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 B1076
B1076 has landed back at the launch site after this flight. Booster B1076 last launched 02/21/2025 and has seen 21 successful launches and landings. Booster first launched the CRS-26 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.
I don’t think Legion 3-4 will be in Sun-Synchronous Orbit
The flight path change at the last minute? Showed southern hemisphere last night , was all set up for it
Unfortunately FlightClub.io had a different flight path previously and we didn’t update our image until last night. FlightClub.io will have the most accurate information.
