  • Artemis II update: Astronauts confront scariest 25,000 mph re-entry . . .
    The 'skip re-entry' profile used on that flight, in which Orion dipped into the upper atmosphere before bouncing back out and re-entering a second time, gave thermal energy enough time to build up
  • ORION ARTEMIS I ENTRY PERFORMANCE - NASA Technical Reports Server (NTRS)
    Skip re-entry improves the down-range capability for precision landing, allowing Orion to return to the continental United States at any time during the lunar month, and improves the survivability from a wide range of return trajectories
  • How the Artemis II Orion Spacecraft Finds Its Way from Earth to the . . .
    For Artemis II, NASA modified the reentry trajectory rather than replacing the already-installed heat shield The new profile eliminates the skip and uses a steeper entry angle, reducing the total time the capsule spends at peak heating temperatures and preventing the pressure buildup that caused the Artemis I damage
  • Orion Skip Maneuver - Lockheed Martin
    Ever skip stones across a pond? Imagine doing it with a spacecraft When NASA’s Orion returns to Earth on Dec 11 at the end of the Artemis I mission, it will attempt a guidance and control maneuver called a skip-entry – the first time a skip entry maneuver will be attempted for a human spacecraft
  • Mission Timeline – Artemis II Mission Tracker | Live Orion 3D Timeline
    Orion enters Earth's atmosphere at the fastest speed any crewed spacecraft has ever returned Skip re-entry technique used to reduce G-forces on crew Three main parachutes deploy to slow Orion to ~32 km h (20 mph) for splashdown Location: Pacific Ocean, off the coast of California Orion splashes down
  • Artemis II Update: Astronauts Confront Scariest… - inkl
    The 'skip re-entry' profile used on that flight, in which Orion dipped into the upper atmosphere before bouncing back out and re-entering a second time, gave thermal energy enough time to build up between passes and crack the shield from within Post-flight inspections revealed more than 100 locations where ablative material had broken free
  • The Space Review: Artemis reentry
    That revised trajectory will limit the “skip” part of the reentry, where the reduced heating causes gas to build up without the charring that allows the gas to be safely released “We need our commercial and international partners to double down to meet and improve this schedule,” Nelson said
  • Artemis II Live Tracker – Real-Time Orion Spacecraft Position, Speed . . .
    Track NASA's Artemis II Orion spacecraft live as it travels to the Moon and back Real-time 2D map with position, speed, distance from Earth and Moon, crew info, mission elapsed time, and trajectory replay for all Artemis missions Free-return trajectory explained
  • Orion Artemis I Entry Performance. | National Technical Reports Library . . .
    Skip re-entry improves the down-range capability for precision landing, allowing Orion to return to the continental United States at any time during the lunar month, and improves the survivability from a wide range of return trajectories
  • Heat shield safety concerns raise stakes for Nasa’s Artemis II Moon mission
    Furthermore, instead of the skip profile, Nasa has now opted for a more direct re-entry mode for the Orion capsule
