Mission
Dragon CRS-2 SpX-31
- Type: Resupply
- Orbit: Low Earth Orbit
- Launch Cost: $52,000,000
31st commercial resupply services mission to the International Space Station operated by SpaceX. The flight will be conducted under the second Commercial Resupply Services contract with NASA.
Cargo Dragon 2 brings supplies and payloads, including critical materials to directly support science and research investigations that occur onboard the orbiting laboratory.
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 199 rockets, including 198 orbital launch attempts. While Kennedy Space Center, FL, USA, has been the site for 257 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 B1083
The Falcon 9 first stage B1083 has landed back at the launch site after its 5th flight. Booster B1083 last launched 01/21/2025 and has seen 8 successful launches and landings. Booster first flown during the Crew-8 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.
GREAT WORK YET AGAIN.
