Mission

425 Project Flight 1 & rideshare

• Type: Government/Top Secret
• Orbit: Sun-Synchronous Orbit
• Launch Cost: $52,000,000

Note: Name of payload is provisional.

First launch of an ultimately 5 reconnaissance satellites for the South Korean Defense Acquisition Program Administration (DAPA), with 1 satellite featuring an electro-optical infrared (EO/IR) telescope. The other 4 synthetic aperture radar (SAR) satellites are to be launched at a later date.

They will be launched to low Earth orbit between 600 and 700 km by 2025, enabling South Korea’s military to observe the nuclear-armed neighbor’s key military facilities every two hours with 30-50 centimeters resolution imagery, according to a 2019 report produced by the Korea Institute of S&T Evaluation and Planning.

The project is lead by the Korean Agency for Defense Development (ADD) and Korea Aerospace Research Institute (KARI), with input from Korea Aerospace Industries (KAI), Hanwha Systems and Thales Alenia Space.

ESA's EIRSAT-1 is also onboard as a rideshare passenger. This 2U cubesat carries three experiments, including a novel gamma ray detector to study some of the most luminous explosions in the universe.

Location

Vandenberg SFB, CA, USA

Find the best place to watch the launch from Vandenberg

Space Launch Complex 4E has witnessed the launch of 180 rockets, including 180 orbital launch attempts. While Vandenberg SFB, CA, USA, has been the site for 792 rocket launches.

Vandenberg Space Force Base is a United States Space Force Base in Santa Barbara County, California. Established in 1941, Vandenberg Space Force Base is a space launch base, launching spacecraft from the Western Range, and also performs missile testing. The United States Space Force's Space Launch Delta 30 serves as the host delta for the base, equivalent to an Air Force air base wing. In addition to its military space launch mission, Vandenberg Space Force Base also hosts space launches for civil and commercial space entities, such as NASA and SpaceX.

Core B1061

B1061 has landed back at the launch site after its 17th flight. Booster B1061 last launched 10/07/2024 and has seen 22 successful launches and landings. Booster which launched Crew-1, Crew-2 and IXPE. Expended for the launch of Hera.

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 4 - LZ-4

LZ at Vandenberg

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.
