Artemis II – Day 3: Navigating Toward the Moon (April 3, 2026)

A more low-key day than the last, but an essential one: fine-tuning the systems, preparing the bodies, and mentally anticipating the big event on Monday. The calm before history!

A day of transition and preparation—the crew is already settling into a deep-space operations rhythm, positioned about 99,900 miles from Earth, with the Moon lying 161,750 miles away.

The crew was awakened to the sound of "…In a Daydream" by the Freddy Jones Band—a highly fitting choice for a team literally traveling toward the horizon.

Highlights:

Trajectory so precise that the corrective burn was cancelled

A trajectory correction burn lasting a mere 8 seconds had been planned to adjust velocity by 0.7 feet per second—a minuscule yet important maneuver. However, the ground team cancelled it because Orion was already heading exactly where it needed to go. This served as a testament to the extraordinary precision of the launch and the TLI burn performed the previous day.

Cabin preparation for the lunar flyby

The four astronauts practiced the "choreography" of moving in microgravity within a space roughly the size of two minivans—stowing equipment, positioning cameras, and configuring the 80–400mm and 14–24mm photographic lenses they would use on Monday. It was a reminder that in space, even the act of moving requires planning and coordination.

Lunar science preparations underway

The ground-based science team began selecting geological targets for the flyby. A fascinating fact: during the flyby, the Sun-Moon-Orion alignment would illuminate approximately 20% of the lunar far side—including features never before seen by the human eye, such as the entire Orientale Basin, Pierazzo Crater, and Ohm Crater.

Medicine and communications

The crew performed demonstrations of CPR and choking response techniques—medical emergency procedures adapted for deep-space environments. Christina Koch also tested Orion’s optical communications system, transmitting high-definition video from the capsule to ground stations, and from there, on to Houston. Everything functioned flawlessly.
