SpaceX’s New Starship HLS Cabin Interior to Land Humans on the Moon for the First Time!

SpaceX has begun assembling the first flight-fidelity Starship HLS crew cabin at Starbase, a milestone directly acknowledged for the first time and confirmed in a NASA Artemis 3 briefing, bringing the program closer to the first crewed lunar landing since Apollo 17. The mission’s complexity hinges on orbital refueling, since the Moon trip requires more propellant than can be carried from Earth, with Starship HLS launching only after its depot is fully fueled. After docking with Orion, the crew transitions from Orion’s cramped 9-cubic-meter cabin into Starship HLS’s roughly 160 cubic meters of pressurized space, featuring a spacious common area, real heated meals, and a touchscreen-based bridge with a context-switching interface. The spacecraft’s closed-loop life support was tested with four people for seven days, matching the planned Artemis 4 lunar stay, while landing is fully autonomous, using small thrusters to avoid blasting regolith and a gentle touchdown the crew only verifies. To reach the surface, astronauts use a large elevator and dual airlocks, solving Apollo-era dust and mobility problems—together underscoring a radically different, far more capable architecture for returning humans to the Moon.

• ▶ 0:00 SpaceX is actively building the first flight-fidelity Starship HLS crew cabin at Starbase, marking the first direct acknowledgment of this hardware.
• ▶ 0:26 In a NASA Artemis 3 briefing, SpaceX's Jessica Jensen confirmed the primary structure is assembled and ready to be outfitted with avionics, power, and life support systems.
• ▶ 1:16 This is a real, physical cabin—not a render—and represents a key milestone toward the first crewed lunar return since Apollo 17 in 1972.
• ▶ 1:45 The mission to reach Starship HLS is more complex than any in history because the Moon trip requires more propellant than can be carried from the ground, so orbital refueling is essential.
• ▶ 2:06 Orbital refueling is a weeks-long, highly complex process that is not safe with crew aboard; only after the depot is fully fueled does Starship HLS launch, dock, and top off its tanks before waiting in low Earth orbit.
• ▶ 2:37 Orion rendezvous and docks with the towering Starship HLS—a 15-story, 50-meter-tall craft—highlighting the extreme scale difference between the two spacecraft.
• ▶ 3:19 Despite the huge solar arrays, deploying them in the vacuum of space creates virtually no drag, so it has no meaningful effect on Starship HLS’s trajectory or velocity.
• ▶ 3:52 Orion docks with Starship HLS using a modern androgynous mechanism, derived from Dragon 2 and optimized for the lunar environment, with over 200 approach scenarios tested by NASA.
• ▶ 4:29 The crew transitions from Orion’s cramped 9-cubic-meter cabin into Starship HLS’s roughly 160 cubic meters of pressurized space—nearly 20 times more volume.
• ▶ 4:45 The astronauts’ first impression is overwhelming physical space and sensory comfort: high ceilings, steady cool air, and warm LED lighting after days shoulder-to-shoulder in Orion.
• ▶ 5:19 Living spaces are a major upgrade over Orion: a spacious common area with a fold-away dining table, real heated meals (not energy bars), refrigerated storage, and a galley designed for microgravity and lunar gravity.
• ▶ 5:55 The bridge replaces traditional cockpit controls with high-resolution touchscreens throughout the ship, using a context-switching interface that adapts to each crew member's role — a completely different philosophy from Dragon's fixed screens.
• ▶ 7:46 The ECLSS is a full closed-loop life support system (CO2 scrubbing, pressure regulation, humidity control, atmospheric monitoring), tested with four people for seven days in a full-scale mockup — matching the planned Artemis 4 lunar stay duration.
• ▶ 8:42 At ~100m, HLS switches from its six main Raptor engines to small gaseous propellant thrusters mounted high on the hull, because even lowest-throttle Raptors would blast dangerous razor-sharp regolith.
• ▶ 9:10 The four landing legs are already deployed, and ranging sensors feed real-time altitude/surface data to the flight computer throughout the final descent.
• ▶ 9:17 The crew only watches and verifies—the ship lands itself, with SpaceX betting on its software; touchdown is so gentle that astronauts may not feel it, but the computer confirms contact and lights up the display.
• ▶ 9:47 Starship HLS uses two separate 13-cubic-meter airlocks, solving Apollo's need to depressurize the entire cabin and avoid dragging sharp lunar dust into living spaces.
• ▶ 10:56 NASA astronauts have tested a full-scale airlock mockup at Hawthorne in fully suited conditions, validating every handhold and motion.
• ▶ 11:12 A unique industrial-style elevator lowers astronauts roughly 35 meters to the surface, because climbing a ladder in a rigid EVA suit under lunar gravity is impractical.
• ▶ 12:40 Audio feed cuts in mid-sentence with “Vehicle,” indicating an ongoing status update.
• ▶ 12:46 Callout notes the vehicle “is pitching down range,” describing trajectory adjustment toward the horizon/downrange.
• ▶ 12:49 Command for “chamber pressures” reflects real-time engine telemetry monitoring during flight.
