Last refreshed: Aug 26, 2025, 7:59 AM EDT. T-Minus Zero keeps this as the canonical launch record and reconciles schedule, mission, payload, media, and provider signals when those records are available.
Live targets are highlighted across the sequence.
Stream links and embedded coverage.
Premium keeps the launch-by-launch change log visible so you can review slips, window edits, and status changes without waiting for an error-driven upgrade prompt.

USSF-36Eighth flight of the X-37B program. The X-37B is a dynamic and responsive spacecraft responsible for conducting a range of tests and experiments that expedite the development of critical next-generation technologies and operational concepts for reusable space capabilities. The OTV-8 mission in Low Earth Orbit includes operational demonstrations and experiments of next-generation technologies, including laser communications and the highest performing strategic grade quantum inertial sensor ever tested in space. Mission partners include the Air Force Research Lab and the Defense Innovation Unit, respectively.
Alternate mission URLs consolidate to this canonical launch record so exact mission timing, status, media, and source context stay on one page.
Use these internal paths to move from this exact launch record into the provider, vehicle, launch-site, schedule, and mission-family pages that own broader context.
This launch currently has no dedicated mission-family hub, so provider, vehicle, site, and canonical record links are the primary internal paths.
Key structured fields for this launch record are grouped here so the page answers mission, payload, orbit, provider, source, and timing questions before the deeper tracking and media sections.
This record is preserved as historical launch context. The page emphasizes what was launched, the vehicle and pad involved, published outcome/status fields, linked programs, and source records instead of treating the mission like an upcoming countdown.

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.
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.
