Summary
Highlights
Rachel Kraft introduces NASA managers Dr. Lori Glaze, Judd Frieling, and Howard Hugh Orion to discuss the Artemis II mission's status. Dr. Glaze announces that for the first time since 1972, humans have left Earth orbit with the successful five-minute and 52-second Translunar Injection (TLI) burn. The four crew members are now on a trajectory to the moon, and the spacecraft is performing well after a series of checkouts.
Judd Frieling details the initial flight checkouts, including successful tests of the water dispenser and toilet, followed by a perigee raise maneuver. He notes a brief and resolved communication outage, the successful apogee raise burn, and the deployment of four CubeSats. The carbon dioxide scrubbers are also confirmed to be working well.
Howard Hugh Orion describes the successful Proximity Operations Demonstration. Astronauts Victor Glover and Reid Wiseman manually maneuvered the spacecraft to test its handling, completing all test objectives. This demonstration provides crucial data for future rendezvous operations, confirming the excellent performance of the spacecraft's manual controls and centerline camera.
Orion highlights the excellent performance of the life support system, including CO2 scrubbing, water distribution, and cabin temperature control, exceeding predictions in some areas. Power generation also performed better than expected. These successes demonstrated the spacecraft's readiness for the TLI burn, ensuring a safe journey for the crew.
Tariq Malik asks about caution alarms during TLI. Judd Frieling explains that fan speed changes caused false cabin leak indications, while RCS manifold messages were known pressure sensor divergences, all quickly identified as non-issues. Eric Berger asks about thruster issues; Orion confirms nominal performance and high confidence in Orion's handling for future Artemis III docking maneuvers.
Mark Kirkman inquires about the crew's views during translunar coast and predicted lunar lighting. Judd Frieling states the vehicle will be in a tail-to-sun attitude mostly, but the crew will have lunar views during a closest approach on flight day six. The moon will be about 20% lit in the observation area.
Jackie Wardell asks about the crew's adjustment and the Cooper-Harper rating scales. Howard Orion confirms crew members are doing great without adaptation issues. Lauren Gresh asks about toilet troubleshooting; Judd explains a partial wetting issue was resolved by adding more water, and both primary and secondary vent lines are confirmed operational. Nell Greenfieldboyce asks about the water dispenser; Judd explains an isolation valve failed, requiring bagging water as a precaution, but full access to water remains.
Marcia Dunn asks about stress levels in Mission Control during TLI and revised lunar flyby distance. Lori Glaze notes calm execution. Judd Frieling calculates a maximum Earth distance of 219,639 nautical miles, confirming it's below the Apollo 13 record. Howard Orion adds that the team maintains professionalism and reflects on the monumental nature of the mission after their shifts.
Andrea Leinfelder asks about module movement during crew exercise and Orion's orbital position during TLI. Judd Frieling clarifies that expected solar dynamics caused no perturbation. Judd confirms Orion was in a high Earth orbit but at perigee (100 nautical miles) during the TLI burn, which then sends them on a free return trajectory around the moon.
Jackie Mogensen asks about overall mission progress and expectations for high-resolution images, specifically for the solar eclipse. Lori Glaze states that everything is going exceptionally well, with no major concerns. She expresses excitement for the crew capturing images of the solar corona during the eclipse beyond the moon.
Michael Atkinson asks about online chatter regarding outlook issues for Reid Wiseman; Judd explains it was a routine software reload. Richard asks about a ground communication issue; Judd details a software bug in the serial communication processor at White Sands. Beverly Casillas inquires about the biggest learning moment so far; Howard highlights the life support system's impressive performance and the ongoing learning regarding caution warning parameters. JJ Love asks about the broader human impact; Lori Glaze emphasizes the mission's role in inspiring youth and pushing technological boundaries.
Robert Pearlman questions if the term 'go for TLI' fully conveys the momentous nature of the burn. Judd Frieling and Howard Orion elaborate that the team operates professionally, saving reflection for after their shifts, acknowledging it as a once-in-a-lifetime moment. Katrina Miller asks about Orion's maximum speed to the moon and crew communication with families. Judd states the maximum speed experienced during TLI was around 24,500 mph, and the crew has not yet had time to speak with families.
Christopher Mick asks about crew schedules and earth observation photos. Judd Frieling explains some tasks were delayed but are now achievable, with plenty of time for observation. Howard Orion confirms the Prox ops demonstration finished ahead of schedule. David Danault questions the mobile launcher damage compared to Artemis I. Lori Glaze reports mostly cosmetic damage, with repairs made after Artemis I proving effective. Philip asks about SLS performance, with Judd confirming the launch was 'right on the money.' Kaya Burgess asks about comparing the free return trajectory to Apollo 13. Judd clarifies the similar use of lunar gravity as an assist to save propellant, unlike Apollo 8's lunar orbit.
An unidentifiable reporter asks about visual expectations when passing the moon. Judd Frieling advises the moon will appear small (like a basketball at arm's length) due to the greater distance than Apollo missions, but modern camera technology will provide sharp images. Lori Glaze adds that high-resolution data downlink will take longer due to bandwidth limitations. Moises Avila asks about differences and similarities to Apollo missions. Howard Orion cites massive advancements in computing, software, sensor capabilities (like GPS and camera for rendezvous), and larger, more efficient spacecraft. He notes that while technology evolves, fundamental physics and engineering principles remain the same.
Will Robinson Smith asks about managing abort scenarios post-TLI. Judd Frieling expresses relief that no aborts were necessary during ascent. He states that a day or two after TLI, a direct abort becomes less feasible, and continuing on the free return trajectory is the most efficient way home. The conference concludes with a thank you to participants and a promise for another update.
