Wow! Artemis 2 Crew Sees Solar Eclipse During Trip Around the Moon

Why It Matters

The eclipse data advances solar‑corona science and validates visual‑observation protocols essential for long‑duration deep‑space travel.

Key Takeaways

• Orion crew witnessed solar eclipse from lunar orbit, unseen on Earth
• Astronauts used eclipse glasses, then observed corona for nearly hour
• Scientists aim to capture corona color, shape, and substructure images
• Earthshine illuminated lunar horizon, revealing stars and planets beyond
• Observations could inform solar physics and deep‑space navigation

Summary

NASA’s Artemis II mission gave the Orion crew a rare chance to watch a solar eclipse from lunar orbit, a phenomenon invisible to anyone on Earth.

During the eclipse the astronauts first wore protective glasses, then, once the Moon fully covered the Sun, they observed the solar corona for almost an hour—far longer than the few minutes of totality experienced on the ground. The crew also noted Earthshine lighting the lunar horizon and the appearance of background stars and planets.

Commander Christina Koch described the view as "a bright halo around the Moon," while pilot Reid Wiseman and mission specialist Jeremy Hansen pointed out the distinct colors and streamers of the corona. The science team emphasized capturing the corona’s visibility, color, and sub‑structures for analysis.

These observations will enrich models of the Sun’s outer atmosphere, test imaging techniques for deep‑space habitats, and provide valuable data for future crewed missions that will operate beyond low‑Earth orbit.

Original Description

NASA's Artemis 2 crew saw the start of a solar eclipse that only they could see from their unique vantage point.
