Artemis II's most valuable lunar data came from astronauts' spoken notes and sketches
NASA released three reports and a data archive from Artemis II on October 7, three days before its six-month deadline. Science News reports that the crew's spoken and written notes proved more valuable than the photos.
The Scientist · Science desk
Key figures: about 7 hours the four Artemis II astronauts spent in close proximity to the moon taking scientific observations; 10 days, the length of their journey around the moon; 54 minutes, when the moon eclipsed the sun and the crew saw the solar corona.
| Figure | Value | Note | Claim |
|---|---|---|---|
| Time close to the moon taking observations, about | 7 hours | 4 | |
| Journey around the moon | 10 days | 3 | |
| Moon eclipsing the sun | 54 minutes | 9 |
What happened
- The results cover the moon's range of colors, how often tiny rocks hit it, and lessons for getting more science out of future crewed lunar missions.
- Four astronauts, Wiseman, Glover, Koch and Hansen, spent about seven hours near the moon taking observations during the April flight.
- The crew worked in pairs: two talked to mission control, while two recorded themselves and annotated moon maps on tablets with a stylus.
- Koch sketched the Orientale basin, noting differences in texture and layers around the crater.
- A 54-minute eclipse gave the crew a view of the solar corona, interplanetary dust, and other stars and planets.
Why it matters
- What's now possible capability Later crews can reuse a tested split of labor: live voice reports to the ground from two members, recorded notes and sketches from the other two.
- What it limits constraint The crew's notes were usable because they trained extensively in lunar geology before launch, so any mission that copies the approach has to budget that training.
- What it sets up precedent The team met a six-month window for releasing crew notes, audio and photos to anyone who wants them, a timetable later missions may be held to.
Science News's account describes the findings on color and micrometeoroid impacts only in outline. It does not include an impact rate or a color measurement, so the size of those results sits in the three reports and the archive [1][2].
The crew trained extensively in lunar geology before launch [15]. Cindy Evans, one of their instructors, said, "You could hear it in their voices. They understood the language of geology." [11] That training was aimed at a question Kelsey Young, the Artemis II flight science operations lead, hears often: what can humans add that a camera can't? [13]
Science News reports that the most valuable data were the astronauts' verbal and written descriptions, not the photographs [6]. Young's answer to her own question was a notebook. She said, "If you have any field experience, you know your field notebook is your best friend." [10] The tablets, the annotated maps and the audio recordings were that notebook. She also defended how rough the sketches look: "They're quick and dirty and that's exactly the right thing to do." [16]
Science News calls the release "a rare test of what trained human observers can add to lunar research" [14]. Four observers on one flyby, with about seven hours near the moon, can show what a trained crew records [4]. In our view they cannot show how much a camera-only mission would have missed over the same terrain, because the flight had no such pass to compare against.
Jennifer Heldmann, a planetary scientist at NASA's Ames Research Center, singled out the eclipse audio. She said, "They were so blown away by what they were seeing, while also taking very relevant science observations." [12]
Sara Schmidt, an earth scientist at NASA in Houston who worked on the release, put the archive's lifespan at decades. She said it "is enabling science to happen for the next, I don't know, 60 years, if not more." [17] The forecast comes from the team that built the archive. Outside researchers have not yet had time to test it.
What to watch
- Whether the three reports put numbers on color variation and micrometeoroid impact rates that outside teams can test against the archive.
- Whether NASA writes the tablet-notebook and paired-observer routine into plans for crewed surface missions.
- Whether independent studies using the archive back Schmidt's expectation of decades of use.

NASA's first Artemis II science results, released October 7 about six months after the mission, reveal details of the moon's array of colors, how often it gets hit by tiny rocks, and lessons for getting as much science as possible out of future human lunar missions.
- [2]
The team released three reports and a massive data archive on October 7, with three days to spare before the six-month deadline after the April 10 splashdown.
- [3]
Artemis II sent four astronauts on a 10-day journey around the moon in April, the first time humans had been anywhere near the moon in more than 50 years.
- [4]
Astronauts Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen spent about seven hours in close proximity to the moon taking scientific observations, describing its colors and textures and witnessing a solar eclipse from space.
- [5]
The astronauts took thousands of photos, notes and audio recordings that were not immediately made public, and the science team's job was to release the data to anyone who wants to study them within six months of splashdown on April 10.
- [6]
The most valuable data from the mission were not the photos but the astronauts' verbal and written descriptions of what they were seeing.
- [7]
During the flyby the astronauts worked in pairs: two spoke to mission control giving periodic updates, while the other two recorded themselves describing observations and used a stylus to annotate specially made moon maps on their tablets.
- [8]
Koch sketched her view of the Orientale basin, detailing differences in texture and layers around the crater.
- [9]
During the 54 minutes when the moon eclipsed the sun, the astronauts had a view of the solar corona, interplanetary dust and other stars and planets.

The astronauts' training was meant to help answer a question Kelsey Young hears often: What can humans add that a camera can't?
- [14]
The results offer a rare test of what trained human observers can add to lunar research and what NASA can learn for future missions to the lunar surface.
- [15]
Before launch the astronauts had extensive training in lunar geology and science observations, and were an extension of the science team.
