Artemis II Science Report: Moon Colors & Impact Flashes
October 11, 2026
NASA's preliminary Artemis II science report reveals 800 GB of new data, confirmed lunar impact flashes, and surprising moon colors seen by the crew.
Last updated: October 11, 2026 (IST). The official Artemis II science report was released by NASA on October 7, 2026, unveiling a treasure trove of new lunar discoveries. Marking the first time humans have traveled near the Moon since Apollo 17 in 1972, this historic flyby yielded groundbreaking observations, from unexpected lunar surface colors to rare meteoroid impact flashes.
1. Artemis II Science Report: Key Facts at a Glance
Before diving into the detailed data, here are the core mission parameters:
- Mission Timeline – The spacecraft flew from April 1 to April 10, 2026, with the critical lunar flyby occurring on April 6, 2026.
- Astronaut Crew – Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and Mission Specialist Jeremy Hansen (CSA, Canada).
- Mission Scope – This was a flyby mission only; there was no lunar landing and no physical samples were collected.
- Observation Time – The crew conducted more than six hours of dedicated lunar observations using handheld Nikon cameras and iPhones.

3. 5 Confirmed Impact Flashes on the Moon Explained
One of the most thrilling Artemis II lunar science results was the visual confirmation of meteoroid strikes. The crew formally reported observing five distinct Artemis II impact flashes while the Moon blocked the Sun from the Orion spacecraft's view, a period of total eclipse lasting approximately 54 minutes.
The science team has officially ruled out cosmic rays and spacecraft reflections as the source of these lights, confirming them as authentic lunar impacts. However, locating the exact new craters using the Lunar Reconnaissance Orbiter (LRO) is currently considered probably infeasible due to the vast search area and orbital resolution limits.
4. The Colorful Moon: Greens and Yellows Seen by Astronauts
Challenging the perception of a monochrome gray world, the Artemis II moon colors described by the crew were surprisingly vibrant. Astronauts reported seeing distinct green, yellow, brown, tan, blue, and beige hues across the lunar surface during their close approach.
These unique color variations are closely linked to different eras of ancient volcanic activity. Specifically, the greenish and yellowish tones observed on the Aristarchus Plateau are being compared by scientists to the famous volcanic glass beads previously collected during the Apollo 15 and Apollo 17 missions.
5. First Human Views of the Lunar Far Side
The Artemis II crew made history as the very first humans to witness parts of the Artemis II far side of the moon directly illuminated by the Sun. This unprecedented vantage point provided high-resolution visual data of heavily cratered terrain that is permanently hidden from Earth's view.
During this phase, the crew focused heavily on terminator observations. Watching how crater darkness changes along the line dividing lunar day and night is highly relevant for future crewed navigation, especially for upcoming missions targeting the shadowed regions of the lunar south pole.

7. India Angle: Chandrayaan and the Artemis Accords
India's ongoing lunar ambitions align perfectly with these new NASA findings:
- Artemis Accords Signatory – India has been a proud signatory of the Artemis Accords since 2023, committing to peaceful and cooperative space exploration alongside NASA.
- Chandrayaan Synergy – The orbital data collected by India's Chandrayaan missions complements the visual observations made by the Artemis II crew, particularly regarding lunar surface composition and crater mapping.
- Future South Pole Goals – The terminator navigation data from Artemis II will benefit all global space agencies, including ISRO, as they plan future robotic and crewed landings near the lunar south pole.
8. How to Access and Explore the Artemis II Images Yourself
The massive Artemis II data release is fully public. Space enthusiasts and independent researchers can access the vast archive of Artemis II photos, including over 11,000 full-resolution images, annotated graphics, and 8.5 hours of science audio, directly through NASA's official Science data portals.
9. What Comes Next for NASA Lunar Science
The NASA Artemis II report October 2026 clearly states that all current findings are strictly PRELIMINARY. Scientists will spend years analyzing this 800 GB dataset. Building on this momentum, NASA announced three new science payloads in late September 2026, specifically designed for upcoming lunar surface landings.
As researchers continue their peer-reviewed analysis, the lessons learned from the Artemis II flyby will directly shape the hardware, navigation protocols, and scientific objectives of the Artemis III landing mission.
