LIVE: NASA's first crewed moon mission in half century
TL;DR
Live coverage from Mission Control Houston captures the Artemis 2 crew approximately 12 hours into their historic lunar mission as they awaken to prepare for the critical Perigee Raise Burn, with teams managing complex orbital maneuvers, environmental systems, and science payloads.
🚀 Critical Mission Milestones 3 insights
Perigee Raise Burn sequencing
The crew was awakened to execute the PRB approximately 12 hours after the April 1st launch, adjusting Orion's orbital geometry to set up for the Trans-Lunar Injection burn scheduled on Flight Day 2.
TLI as trajectory commitment
The Trans-Lunar Injection burn serves as both the final major engine firing to reach the moon and the de-orbit burn, committing the spacecraft to a free-return trajectory around the lunar far side.
Lunar approach timeline
Following TLI, three smaller outbound trajectory correction burns will refine the path, culminating in the crew entering the moon's sphere of influence on Flight Day 5 and conducting the closest lunar flyby on Flight Day 6.
👨🚀 Crew Activities & Systems 3 insights
Environmental and operational adjustments
Mission specialist Christina Koch reported dangerously cold cabin temperatures, prompting Houston to modify radiator set points and consider shell heaters while the crew prepared for critical burns.
Science payload coordination
The crew collaborated with Huntsville's Payload Operations Integration Center to monitor Avatar, an organ-on-chip experiment studying radiation and microgravity effects to inform future astronaut medical countermeasures.
Communication protocols and traditions
The crew participated in pre-burn conferences with Capcom to verify procedure alignment, while wake-up music traditions dating to the Apollo era marked shift changes.
🛰️ Navigation & Flight Control 3 insights
Precision targeting sequence
The Guidance, Navigation, and Control team commanded starfield maneuvers using Orion's star tracker cameras to determine spacecraft attitude before uploading final burn targeting parameters.
24/7 mission oversight
Three rotating flight controller shifts (Orbit 1, 2, and 3) monitor the spacecraft continuously from Houston, with Orbit 2 led by Flight Director Paul Ka managing the PRB preparation.
High Earth orbit positioning
Orion currently travels approximately 43,000 miles from Earth—over 165 times farther than the ISS—positioning it for the critical lunar injection maneuver.
Bottom Line
Successful execution of the upcoming Trans-Lunar Injection burn represents the mission's critical commitment point, irreversibly propelling the crew toward their historic lunar flyby and return trajectory.
