In this episode of the Curiosity Well, we break down the exact timeline of Flight Day 3 of the Artemis II mission. We cover the crew's transition from Low Earth Orbit into cislunar space, marking the first time humans have operated in this region since 1972. We detail the physical mechanics of spacecraft venting and explain why Mission Control officially scrubbed the Outbound Trajectory Correction (OTC-1) burn.

We also examine the realities of emergency medical procedures in microgravity, outlining how astronauts perform CPR and choking-response protocols without the assistance of Earth's gravity. Additionally, we discuss a minor helium pressurization glitch in the Orion service module that successfully validated NASA's redundant backup systems, and we outline the crew's specific camera preparations for their upcoming pass over the lunar far side.

We are officially lunar-bound! On this episode, we break down the exact, minute-by-minute timeline of Flight Day 2 of the historic Artemis II mission. After a busy first 24 hours, Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialists Christina Koch and Jeremy Hansen fired the European Service Module's main engine to commit the Orion spacecraft to a lunar transit trajectory.

From early morning orbital raise maneuvers to testing deep-space laser communications, we cover all the manual hardware tests, cabin environment adjustments, and mid-flight troubleshooting that took place on April 2nd, 2026. Join us as we track Orion's transition out of standard Earth orbit and into the hands of the Deep Space Network.

Artemis II Day-One Update: Liftoff, Orion Checkout, and the Upcoming Trans-Lunar Injection Burn

The episode recaps the Artemis II launch from Kennedy Space Center’s Launch Complex 39B at 6:35 PM Eastern on April 1, describing SLS ignition with twin solid rocket boosters and four RS-25 engines producing 8.8 million pounds of thrust, Orion’s separation from the core stage, and successful deployment of four solar arrays. It explains Orion’s first major burn to raise apogee and outlines the crew’s early tasks, including a Proximity Operations Demonstration in which Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen manually flew Orion near the spent upper stage to practice future docking skills. The crew also reported a blinking fault light on the space toilet as Mission Control troubleshoots. The update previews the mission’s most critical maneuver ahead: the 20+ minute trans-lunar injection burn to place Orion on a trajectory toward the Moon.
