Artemis II NASA astronauts (left to right) Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen stand in the white room on the crew access arm of the mobile launcher at Launch Pad 39B as part of an integrated ground systems test at Kennedy Space Center in Florida on Wednesday, Sept. 20, 2023. The test ensures the ground systems team is ready to support the crew timeline on launch day.NASA/Frank Michaux With Artemis II, NASA is taking the science of living and working in space beyond low Earth orbit. While the test flight will help confirm the systems and hardware needed for human deep space exploration, the crew also will be serving as both scientists and volunteer research subjects, completing a suite of experiments that will allow NASA to better understand how human health may change in deep space environments. Results will help the agency build future interventions, protocols, and preventative measures to best protect astronauts on future missions to the lunar surface and to Mars.
Science on Artemis II will include seven main research areas:
ARCHeR: Artemis Research for Crew Health and Readiness
NASA’s Artemis II mission provides an opportunity to explore how deep space travel affects sleep, stress, cognition, and teamwork — key factors in astronaut health and performance. While these effects are well-documented in low Earth orbit, they’ve never been fully studied during lunar missions.
Artemis II astronauts will wear wristband devices that continuously monitor movement and sleep patterns throughout the mission. The data will be used for real-time health monitoring and safety assessments, while pre- and post-flight evaluations will provide deeper insights into cognition, behavior, sleep quality, and teamwork in the unique environment of deep space and the Orion spacecraft.
The findings from the test flight will inform future mission planning and crew support systems, helping NASA optimize human performance for the next era of exploration on the Moon and Mars.
Immune Biomarkers
Saliva provides a unique window into how the human immune system functions in a deep space environment. Tracing changes in astronauts’ saliva from before, during, and after the mission will enable researchers to investigate how the human body responds to deep space in unprecedented ways.
Dry saliva will be collected before, during, and after the mission. It will be blotted onto specialized paper in pocket-sized booklets since equipment needed to preserve wet spit samples in space – including refrigeration – will not be available due to volume constraints. To augment that information, liquid saliva and blood samples will be collected before and after the mission.
NASA Astronaut Randy Bresnik prepares to collect a dry saliva sample aboard the International Space Station. The process, which helps scientists investigate how the immune system is affected by spaceflight and will be part of the Artemis II mission, involves blotting saliva onto special paper that’s stored in pocket-sized booklets.Credit: NASA With these wet and dry saliva samples, scientists will gain insights into how the astronauts’ immune systems are affected by the increased stresses of radiation, isolation, and distance from Earth during their deep space flight. They also will examine whether otherwise dormant viruses are reactivated in space, as has been seen previously on the International Space Station with viruses that can cause chickenpox and shingles.
The information gathered from this study, when combined with data from other missions, will help researchers develop ways to keep crew members safe and healthy as we explore farther and travel for longer periods on deep space missions.
AVATAR: A Virtual Astronaut Tissue Analog Response
AVATAR is another important component of NASA’s strategy to gain a holistic understanding of how the deep space environment affects humans. Scientists plan to use organ-on-a-chip technology during Artemis II, marking the first time these devices will be used beyond the Van Allen belts.
Roughly the size of a USB thumb drive, the chips will measure how individual astronauts respond to deep space stressors, including extreme radiation and microgravity. The organ chips will contain cells developed from preflight blood donations provided by crew members to create miniature stand-ins, or “avatars,” of their bone marrow. Bone marrow plays a vital role in the immune system and is particularly sensitive to radiation, which is why scientists selected it for this study.

A key goal for this research is to validate whether organ chips can serve as accurate tools for measuring and predicting human responses to stressors. To evaluate this, scientists will compare AVATAR data with space station findings, as well as with samples taken from the crew before and after flight.
AVATAR could inform measures to ensure crew health on future deep space missions, including personalizing medical kits to each astronaut. For citizens on Earth, it could lead to advancements in individualized treatments for diseases such as cancer.
AVATAR is a demonstration of the power of public-private partnerships. It’s a collaboration between government agencies and commercial space companies: NASA, National Center for Advancing Translational Sciences within the National Institutes of Health, Biomedical Advanced Research and Development Authority, Space Tango, and Emulate.
Artemis II Standard Measures
The crew also will become the first astronauts in deep space to participate in the Spaceflight Standard Measures study, an investigation that’s been collecting data from participating crew members aboard the space station and elsewhere since 2018. The study aims to collect a comprehensive snapshot of astronauts’ bodies and minds by gathering a consistent set of core measurements of physiological response.
The crew will provide biological samples including blood, urine, and saliva for evaluating nutritional status, cardiovascular health, and immunological function starting about six months before their launch. The crew also will participate in tests and surveys evaluating balance, vestibular function, muscle performance, changes in their microbiome, as well as ocular and brain health. While in space, data gathering will include an assessment of motion sickness symptoms. After landing, there will be additional tests of head, eye, and body movements, among other functional performance tasks. Data collection will continue for a month after their return.
All this information will be available for scientists interested in studying the effects of spaceflight via request to NASA’s Life Sciences Data Archive. The results from this work could lead to future interventions, technologies, and studies that help predict the adaptability of crews on a Mars mission.
Radiation Sensors Inside Orion
During the uncrewed Artemis I mission, Orion was blanketed in 5,600 passive and 34 active radiation sensors. The information they gathered assured researchers Orion’s design can provide protection for crew members from hazardous radiation levels during lunar missions. That doesn’t mean that scientists don’t want more information, however.
Similar to Artemis I, six active radiation sensors, collectively called the Hybrid Electronic Radiation Assessors, will be deployed at various locations inside the Orion crew module. Crew also will wear dosimeters in their pockets. These sensors will provide warnings of hazardous radiation levels caused by space weather events made by the Sun. If necessary, this data will be used by mission control to drive decisions for the crew to build a shelter to protect from radiation exposure due to space weather.
Additionally, NASA has again partnered the German Space Agency DLR for an updated model of their M-42 sensor – an M-42 EXT – for Artemis II. The new version offers six times more resolution to distinguish between different types of energy, compared to the Artemis I version. This will allow it to accurately measure the radiation exposure from heavy ions which are thought to be particularly hazardous for radiation risk. Artemis II will carry four of the monitors, affixed at points around the cabin by the crew.
Collectively, sensor data will paint a full picture of radiation exposures inside Orion and provide context for interpreting the results of the ARCHeR, AVATAR, Artemis II Standard Measures, and Immune Biomarkers experiments.
Lunar Observations Campaign
The Artemis II crew will take advantage of their location to explore the Moon from above. As the first humans to see the lunar surface up close since 1972, they’ll document their observations through photographs and audio recordings to inform scientists’ understanding of the Moon and share their experience of being far from Earth. It’s possible the crew could be the first humans to see certain areas of the Moon’s far side, though this will depend on the time and date of launch, which will affect which areas of the Moon will be illuminated and therefore visible when the spacecraft flies by.
Spacecraft such as NASA’s Lunar Reconnaissance Orbiter have been surveying and mapping the Moon for decades, but Artemis II provides a unique opportunity for humans to evaluate the lunar surface from above. Human eyes and brains are highly sensitive to subtle changes in color, texture, and other surface characteristics. Having the crew observe the lunar surface directly – equipped with questions that scientists didn’t even know to ask during Apollo missions – could form the basis for future scientific investigations into the Moon’s geological history, the lunar environment, or new impact sites.
This visualization simulates what the crew of Artemis II might see out the Orion windows on the day of their closest approach to the Moon. It compresses 36 hours into a little more than a minute as it flies the virtual camera on a realistic trajectory that swings the spacecraft around the Moon’s far side. This sample trajectory is timed so that the far side is fully illuminated when the astronauts fly by, but other lighting conditions are possible depending on the exact Artemis II launch date. The launch is scheduled for no later than April of 2026. NASA Goddard/Ernie Wright
It will also offer the first opportunity for an Artemis mission to integrate science flight control operations. From their console in the flight control room in mission control, a science officer will consult with a team of scientists with expertise in impact cratering, volcanism, tectonism, and lunar ice, to provide real-time data analysis and guidance to the Artemis II crew in space. During the mission, the lunar science team will be located in mission control’s Science Evaluation Room at NASA’s Johnson Space Center in Houston.
Lessons learned during Artemis II will pave the way for lunar science operations on future missions.
CubeSats
Several additional experiments are hitching a ride to space onboard Artemis II in the form of CubeSats – shoe-box-sized technology demonstrations and scientific experiments. Though separate from the objectives of the Artemis II mission, they may enhance understanding of the space environment.

Credit: NASA Four international space agencies have signed agreements to send CubeSats into space aboard the SLS (Space Launch System) rocket, each with their own objectives. All will be released from an adapter on the SLS upper stage into a high-Earth orbit, where they will conduct an orbital maneuver to reach their desired orbit.
ATENEA – Argentina’s Comisión Nacional de Actividades Espaciales will collect data on radiation doses across various shielding methods, measure the radiation spectrum around Earth, collect GPS data to help optimize future mission design, and validate a long-range communications link.
K-Rad Cube – The Korea Aerospace Administration will use a dosimeter made of material designed to mimic human tissue to measure space radiation and assess biological effects at various altitudes across the Van Allen radiation belt.
Space Weather CubeSat – The Saudi Space Agency will measure aspects of space weather, including radiation, solar X-rays, solar energetic particles, and magnetic fields, at a range of distances from Earth.
TACHELES – The Germany Space Agency DLR will collect measurements on the effects of the space environment on electrical components to inform technologies for lunar vehicles.
Together, these research areas will inform plans for future missions within NASA’s Artemis campaign. Through Artemis, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.

Webb captured this sparkling scene of star birth in Pismis 24. Full image and caption below. Credits:
Image: NASA, ESA, CSA, STScI; Image Processing: A. Pagan (STScI) This is a sparkling scene of star birth captured by NASA’s James Webb Space Telescope. What appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being eaten away by the blistering winds and radiation of nearby, massive, infant stars.
Called Pismis 24, this young star cluster resides in the core of the nearby Lobster Nebula, approximately 5,500 light-years from Earth in the constellation Scorpius. Home to a vibrant stellar nursery and one of the closest sites of massive star birth, Pismis 24 provides rare insight into large and massive stars. Its proximity makes this region one of the best places to explore the properties of hot young stars and how they evolve.
At the heart of this glittering cluster is the brilliant Pismis 24-1. It is at the center of a clump of stars above the jagged orange peaks, and the tallest spire is pointing directly toward it. Pismis 24-1 appears as a gigantic single star, and it was once thought to be the most massive known star. Scientists have since learned that it is composed of at least two stars, though they cannot be resolved in this image. At 74 and 66 solar masses, respectively, the two known stars are still among the most massive and luminous stars ever seen.

Webb captured this sparkling scene of star birth in Pismis 24, a young star cluster about 5,500 light-years from Earth in the constellation Scorpius. This region is one of the best places to explore the properties of hot young stars and how they evolve. Image: NASA, ESA, CSA, STScI; Image Processing: A. Pagan (STScI) Captured in infrared light by Webb’s NIRCam (Near-Infrared Camera), this image reveals thousands of jewel-like stars of varying sizes and colors. The largest and most brilliant ones with the six-point diffraction spikes are the most massive stars in the cluster. Hundreds to thousands of smaller members of the cluster appear as white, yellow, and red, depending on their stellar type and the amount of dust enshrouding them. Webb also shows us tens of thousands of stars behind the cluster that are part of the Milky Way galaxy.
Super-hot, infant stars –some almost 8 times the temperature of the Sun – blast out scorching radiation and punishing winds that are sculpting a cavity into the wall of the star-forming nebula. That nebula extends far beyond NIRCam’s field of view. Only small portions of it are visible at the bottom and top right of the image. Streamers of hot, ionized gas flow off the ridges of the nebula, and wispy veils of gas and dust, illuminated by starlight, float around its towering peaks.
Dramatic spires jut from the glowing wall of gas, resisting the relentless radiation and winds. They are like fingers pointing toward the hot, young stars that have sculpted them. The fierce forces shaping and compressing these spires cause new stars to form within them. The tallest spire spans about 5.4 light-years from its tip to the bottom of the image. More than 200 of our solar systems out to Neptune’s orbit could fit into the width its tip, which is 0.14 lightyears.
In this image, the color cyan indicates hot or ionized hydrogen gas being heated up by the massive young stars. Dust molecules similar to smoke here on Earth are represented in orange. Red signifies cooler, denser molecular hydrogen. The darker the red, the denser the gas. Black denotes the densest gas, which is not emitting light. The wispy white features are dust and gas that are scattering starlight.

Patricia White is a contracting officer at NASA’s Stennis Space Center, where she contributes to NASA’s Artemis program that will send astronauts to the Moon to prepare for future human exploration of Mars. NASA/Danny Nowlin When NASA’s Artemis II mission launches in 2026, it will inspire the world through discovery in a new Golden Age of innovation and exploration.
It will be another inspiring NASA moment Patricia White can add to her growing list.
White supports the Artemis program to send astronauts to the Moon to prepare for future human exploration of Mars as a contracting officer at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.
White takes special pride in the test operations contract she helped draft. The contract provides support to the Fred Haise Test Stand, which tests the RS-25 engines that will help power NASA’s SLS (Space Launch System) rocket on Artemis missions.
“I was awestruck the first time I witnessed an engine test,” White said. “I remember how small I felt in comparison to this big and fascinating world, and I wondered what that engine would see that I would never be able to see.”
Four RS-25 engines tested at NASA Stennis will help launch Artemis II with four astronauts to venture around the Moon. As the first crewed Artemis mission, it will represent another milestone for the nation’s human space exploration effort.
From Interstate Signs to NASA Career
White describes NASA Stennis as a hidden gem. Growing up in nearby Slidell, Louisiana, she had driven by the interstate signs pointing toward NASA Stennis her entire life.
When she heard about a job opportunity at the center, she immediately applied. Initially hired as a contractor with only a high school diploma in February 2008, White found her motivation among NASA’s ranks.
“I work with very inspiring people, and it only took one person to say, ‘You should go to college’ to give me the courage to go so late in life,” she said.
Hard But Worth It
White began college classes in her 40s and finished at 50. She balanced a marriage, full-time job, academic studies, and household responsibilities. When she started her educational journey, her children were either toddlers or newborns. They were growing up as she stayed in school for nine years while meeting life’s challenges.
“It was hard, but it was so worth it,” she said. “I love my job and what I do, and even though it is crazy busy, I look forward to working at NASA every single day.”
She joined NASA officially in 2013, going from contractor to civil servant.
Setting an Example
White’s proudest work moment came when she brought home the NASA Early Career Achievement award and medal. It served as a tangible symbol of her success she could share with her family.
“It was a long road from being hired as an intern, and we all made extraordinary sacrifices,” she said. “I wanted to share it with them and set a good example for my children.”
As Artemis II prepares to carry humans back to lunar orbit for the first time in over 50 years, White takes pride knowing her work helps power humanity’s return to deep space exploration. Her work is proof that sometimes the most important journeys begin right in one’s own backyard.
