Artemis II Science and Lunar Exploration: Geology, Training, and Human Research

Episode snapshot

In this episode of NASA's Curious Universe, the Artemis II science lead explains how the crew will study the Moon from orbit, train on Earth to conduct lunar geology, and participate in human health research. The discussion connects lunar science to future Artemis missions and Mars exploration.

Key insights

• Artemis II will image and characterize large lunar regions from lunar orbit and compare observations with past Apollo data.
• The mission emphasizes the Moon as a witness plate for solar system history and lunar geology as a gateway to understanding planetary formation.
• A field geology training program uses Icelandic craters as analogs to prepare astronauts for lunar observations and sampling strategies.
• Human research experiments explore immune biomarkers, tissue analogs on organ chips, sleep, and performance to ensure astronaut health on longer deep space missions.

Overview

The podcast presents Artemis II as a bridge to Artemis III and a stepping stone toward human exploration of Mars. The Artemis II mission will place four astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen in lunar orbit aboard Orion to observe the Moon more comprehensively than has been possible since the Apollo era. The episode emphasizes science as a core driver of the mission and frames the crew as scientific ambassadors who will observe, sample, and interpret lunar features in real time with guidance from NASA scientists on the ground.

Lunar science and analog training

Kelsey Young, the lunar science lead for Artemis II, and her colleagues train the crew to conduct geology in the field as analogs to lunar surface science. Apollo rocks collected in the past laid the groundwork for understanding lunar formation and the Earth Moon system. Artemis II will leverage enhanced observational capabilities, including color and albedo measurements and the ability to view the Moon over extended lighting conditions, which can reveal surface features that robotic missions might miss. Because the lunar surface presents extreme environments, analog field sites on Earth are used to develop observation skills and sampling strategies. Icelandic craters and other analog environments provide a way to practice field geology in a setting that mimics some lunar and Martian conditions.

Mission control and science targeting

The mission includes three rooms in Mission Control for science: the front room with a Science Officer, the science evaluation room acting as a brain trust, and the Science Mission Operations Room (the SMORE) that coordinates data analysis. The science team must prepare for a launch day with lighting conditions that will influence which lunar features are visible. They will condense a long feature list into a prioritized set of targets in a 45 minute loss of signal window during which astronauts image and observe the Moon, guided by a preloaded targeting plan on tablets. The team trains through simulations to handle compromises and ensure robust science goals for the mission.

Earthrise and Artemis III implications

Observations could reveal regions that inform Artemis III landing site selection, particularly near the Moon's south polar region. Earthrise, a historic Apollo-era image, is expected to be reproduced in a new context as a targeted science objective. The episode highlights how Artemis II could help place Artemis III in the broader context of lunar history and its relationship to Mars exploration as NASA lays the groundwork for a long term lunar presence and human missions to the Red Planet.

Human research and RIDGE hazards

The podcast introduces the five RIDGE hazards that NASA studies for human spaceflight: radiation, isolation and confinement, distance from Earth, gravity, and the environment. Jancy McPhee, a neuroscientist with NASA’s Human Research Program, explains how these hazards affect the crew and outlines the experiments designed to monitor immune function, gene regulation, and cognitive performance in space. Immune biomarkers, avatar organ on a chip experiments, and Archer protocols for sleep and sensory/motor testing illustrate how scientists study health and readiness for deep space missions, including a future Mars habitat.

Experiments and daily life in Artemis II

Spit sample analysis for immune biomarkers, organ on a chip avatars, actigraphy for sleep, and testing for cognitive and perceptual changes are among the experiments described. The crew participates voluntarily, reflecting a culture of science-driven exploration. The discussion also covers training for surface operations and the readiness to perform field geology in lunar gravity, as well as the steps after landing for evaluation, sample return, and data analysis.

Looking ahead

The episode closes with reflections on Apollo lessons, the ongoing human health research program, and the anticipation of a new era of crewed exploration. Artemis II is portrayed as a critical precursor that can shape Artemis III operations, contribute to lunar science, and inform strategies for human exploration of Mars and beyond.
