SLS stage separation video posted

A newly posted long-lens video from Florida shows NASA’s Space Launch System shutting down its core engines and dropping its first stage away in flight. (x.com) In rocket launches, stage separation is the handoff between one set of engines and the next: the lower stage burns most of the fuel, then falls away so a lighter upper stage can keep pushing. NASA says the Space Launch System’s core stage is designed to run for about 500 seconds before separating from the upper stage and Orion spacecraft. (nasa.gov) On Artemis I, NASA’s mission timeline put core stage main engine cutoff at 8 minutes, 3 seconds after liftoff, with core stage separation logged at the same mission elapsed time. NASA’s live mission blog on November 16, 2022, said the core stage had separated from the interim cryogenic propulsion stage and Orion spacecraft. (nasa.gov 1) (nasa.gov 2) The sequence matters because the core stage is the biggest single piece of the rocket: NASA says it stands 212 feet tall, holds liquid hydrogen and liquid oxygen, and feeds four RS-25 engines. Once that propellant is spent, carrying the empty stage further would waste performance. (nasa.gov) NASA says the upper stage on the Block 1 version of Space Launch System is the interim cryogenic propulsion stage, a hydrogen-and-oxygen stage powered by one RL10 engine. Its job is to take over after core stage separation and continue pushing Orion on its path beyond low Earth orbit. (nasa.gov) (ulalaunch.com) NASA’s own engineering teams treat separation as a high-risk event because two large pieces of hardware are still moving at nearly the same speed and must peel away cleanly. The agency says analysts model those breaks to make sure the discarded hardware does not strike the spacecraft that keeps flying. (nasa.gov) The clip is landing at a moment when Space Launch System is no longer just a test article. NASA says Artemis II launched on April 1, 2026, with Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen aboard Orion, then splashed down on April 10 after a 9-day, 1-hour, 32-minute mission. (nasa.gov 1) (nasa.gov 2) That makes a clean view of main engine cutoff and stage separation more than launch footage: it is a close look at the exact handoff that every crewed Space Launch System mission has to survive. In this case, the camera caught the moment the Moon rocket shed 212 feet of empty hardware and kept going. (nasa.gov 1) (nasa.gov 2)
