Earth Day 2026 coincided with the return of NASA's Artemis II, the first crewed lunar flyby in 50 years. The nearly 10-day mission carried four astronauts to a record distance and produced rare, high-quality photos of Earth from deep space. Christina Koch shared a moving image and caption, and the crew captured scientifically valuable images after specialized photography training.

This year’s observance comes days after NASA’s Artemis II mission returned to Earth. The nearly 10-day, crewed lunar flyby — the first in 50 years — carried four astronauts to a record distance from our planet and delivered rare, powerful views of Earth from deep space.

The Artemis II crew captured striking images of Earth that combine aesthetic impact with scientific usefulness. Those photographs followed specialized training in long‑distance planetary photography and careful use of onboard imaging equipment.

Every triumph, every tear, every birthday cake, every disappointment, every skinned knee, every dust off, every draped flag, every first dance, every missed flight, every shift change, every twirl hug, every wave goodbye, every love note, every human. Us. You. All we have.
Artemis astronaut Christina Koch shared one of those images on Instagram alongside the poignant reflection above, a post that echoes Carl Sagan’s well-known perspective on humanity's fragility and unity.

NASA staff and collaborators worked with the crew to teach techniques that go beyond basic photography. "Most people can use a camera and get a photo that is good enough, but good enough isn't what we're after scientifically," said Katrina Willoughby, a NASA employee and RIT graduate. "We're really teaching the astronauts how to go beyond the basics. Being able to understand how to use the equipment, and what the options are, gives us a lot more capability."

Why These Photos Matter
Beyond their emotional resonance, the images help scientists monitor Earth systems, refine imaging methods for future missions, and connect the public to space exploration. As Artemis missions continue, high-quality imagery from deep space will remain a valuable tool for science, outreach and inspiration.
