Highlights
Lori Glaze announces the successful five-minute and 52-second Translunar Injection burn, marking the first time humans have left Earth orbit since Apollo 17 in 1972. The four crew members, NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen, are now on an unpowered trajectory toward the Moon. The spacecraft is performing well, and the crew is healthy. She emphasizes that this is still a test flight, continually yielding new data. She shares images of Earth from the spacecraft and a crew photo from the proximity operations demonstration.
Judd Frieling details the mission's technical aspects, including successful initial checkouts of the water dispenser and toilet, a brief comm outage due to a rectifiable ground issue, and the Intermediary Cryogenic Propulsion Stage (ICPS) burns that placed Orion in high Earth orbit. He highlights the proximity operations demonstration by Victor Glover, carbon dioxide scrubber checkouts, CubeSat deployment, and a successful perigee raise burn. He concludes by confirming the critical Translunar Injection burn, setting the stage for a free return around the Moon and splashdown in San Diego.
Howard Hu shares his excitement for the mission's first two days, emphasizing Orion's perfect ride to orbit and successful TLI. He elaborates on the proximity operations demonstration where Victor Glover and Reid Wiseman manually maneuvered the spacecraft. This test successfully achieved all objectives, providing valuable data on the spacecraft's handling for future rendezvous operations. He also reports that the life support systems, including CO2 scrubbers, water distribution, and temperature control, are performing as predicted or better. Power generation is also exceeding expectations.
Judd Frieling addresses questions about caution alarms during TLI, explaining false indications linked to cabin fan speed changes and known pressure sensor divergences in the reaction control system. He confirms these were not critical issues. The discussion also covers the low-stress environment in Mission Control due to extensive simulations and the team's professionalism.
Howard Hu mentions the crew's positive feedback on the spacecraft's handling, particularly during manual piloting. Judd Frieling clarifies a troubleshooting moment with the toilet: it needed more water to prime the pump and operate correctly. Lori Glaze adds that this was a valuable learning experience for operating within the Orion capsule. He also confirms the crew is healthy and not experiencing any adaptation issues.
Judd clarifies the anticipated maximum distance from Earth as 219,639 nautical miles, based on nominal burn performance, which is close to Apollo's record. Lori Glaze expresses excitement about the upcoming solar eclipse viewing from beyond the Moon, an event the crew has been trained for. The crew will have views of the lunar surface during a planned attitude change on flight day six, although the moon will appear smaller due to the greater distance.
Howard Hu explains a temporary communication issue caused by a ground software bug at the White Sands Ground Terminal, which has been identified and will not affect future operations. Judd Frieling confirms that the lunar eclipse is expected on flight day six and a ship-to-ship communication event with the International Space Station is planned for flight day seven. He reports that some tasks were not completed due to a packed schedule but the crew will have more time for observations now that the TLI is complete.
Howard Hu discusses the significant technological advancements in the current mission compared to the Apollo era, such as enhanced computing capabilities, electronic procedures, and precise navigation systems. He highlights the larger spaceship design and smaller components for increased functionality. He emphasizes that while physics remains constant, these advancements make operations easier and more efficient for the crew. Lori Glaze adds that the mission aims to inspire future generations and push the boundaries of technology.
