SpaceX is in the final stretch of its countdown for the USSF-481 mission, with a Falcon 9 standing ready at Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California. Propellant loading is underway, all systems are nominal, and weather is cooperating — the launch is live and watchable right now.
1. The mission is a U.S. Space Force payload
USSF-481 is a dedicated mission for the United States Space Force, making it part of the ongoing national security launch cadence that SpaceX has built with the U.S. government. Details on the specific payload remain classified, as is standard for USSF missions — SpaceX confirms the mission designation and launch site, but the payload's purpose and orbital destination are not publicly disclosed.
2. The launch site is SLC-4E at Vandenberg
Space Launch Complex 4E on California's Central Coast is SpaceX's West Coast workhorse, primarily used for polar and sun-synchronous orbits. A Vandenberg launch trajectory is consistent with a national security satellite that needs coverage over the poles — a common requirement for reconnaissance and surveillance assets operated by the Space Force.
3. All systems are nominal and weather is favorable
SpaceX confirmed via X that all systems are looking good heading into propellant load, with weather conditions favorable for liftoff. Vandenberg can be temperamental — marine layer and coastal winds are common constraints — so a clean weather call this close to launch is a meaningful green light. A backup opportunity was available on Friday, October 16, according to the mission schedule, but the team appeared on track for the primary window.
4. Propellant loading is the last major milestone before ignition
When SpaceX announces propellant loading has begun, the countdown is in its final phase. Liquid oxygen and RP-1 (refined kerosene) are loaded into the Falcon 9's first and second stages in the roughly 35 minutes before liftoff. Once fueling is complete, the launch director conducts a final go/no-go poll before the automated sequence takes over in the last few minutes of the count.
5. The launch webcast is live on X
SpaceX posted the live stream link directly to X, making it easy to watch without navigating away. The webcast typically begins a few minutes before liftoff and covers first-stage separation, second-stage burn, and — when mission security permits — booster landing. For USSF missions, SpaceX sometimes cuts the feed after payload deployment rather than showing the full orbital insertion sequence.
