NASA Selects 2 Instruments for Artemis IV Lunar Surface Science
NASA has selected two science instruments designed for astronauts to deploy on the surface of the Moon during the Artemis IV mission to the lunar south polar region. The instruments will improve our knowledge of the lunar environment to support NASA’s further exploration of the Moon and beyond to Mars.
A visualization of the Moon’s South Pole region created with data from NASA’s Lunar Reconnaissance Orbiter, which has been surveying the Moon with seven instruments since 2009.
“The Apollo Era taught us that the further humanity is from Earth, the more dependent we are on science to protect and sustain human life on other planets,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “By deploying these two science instruments on the lunar surface, our proving ground, NASA is leading the world in the creation of humanity’s interplanetary survival guide to ensure the health and safety of our spacecraft and human explorers as we begin our epic journey back to the Moon and onward to Mars.”
After his voyage to the Moon’s surface during Apollo 17, astronaut Gene Cernan acknowledged the challenge that lunar dust presents to long-term lunar exploration. Moon dust sticks to everything it touches and is very abrasive. The knowledge gained from the DUSTER (DUst and plaSma environmenT survEyoR) investigation will help mitigate hazards to human health and exploration. Consisting of a set of instruments mounted on a small autonomous rover, DUSTER will characterize dust and plasma around the landing site. These measurements will advance understanding of the Moon’s natural dust and plasma environment and how that environment responds to the human presence, including any disturbance during crew exploration activities and lander liftoff. The DUSTER instrument suite is led by Xu Wang of the University of Colorado Boulder. The contract is for $24.8 million over a period of three years.
A model of the DUSTER instrument suite consisting of the Electrostatic Dust Analyzer (EDA)—which will measure the charge, velocity, size, and flux of dust particles lofted from the lunar surface—and Relaxation SOunder and differentiaL VoltagE (RESOLVE)—which will characterize the average electron density above the lunar surface using plasma sounding. Both instruments will be housed on a Mobile Autonomous Prospecting Platform (MAPP) rover, which will be supplied by Lunar Outpost, a company based in Golden, Colorado, that develops and operates robotic systems for space exploration.

Data from the SPSS (South Pole Seismic Station) will enable scientists to characterize the lunar interior structure to better understand the geologic processes that affect planetary bodies. The seismometer will help determine the current rate at which the Moon is struck by meteorite impacts, monitor the real-time seismic environment and how it can affect operations for astronauts, and determine properties of the Moon’s deep interior. The crew will additionally perform an active-source experiment using a “thumper” that creates seismic energy to survey the shallow structure around the landing site. The SPSS instrument is led by Mark Panning of NASA’s Jet Propulsion Laboratory in Southern California. The award is for $25 million over a period of three years.

“These two scientific investigations will be emplaced by human explorers on the Moon to achieve science goals that have been identified as strategically important by both NASA and the larger scientific community”, said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate at NASA Headquarters. “We are excited to integrate these instrument teams into the Artemis IV Science Team.”
The two payloads were selected for further development to fly on Artemis IV; however, final manifesting decisions about the mission will be determined at a later date.
Through Artemis, NASA will address high priority science questions, focusing on those that are best accomplished by on-site human explorers on and around the Moon and by using the unique attributes of the lunar environment, aided by robotic surface and orbiting systems. The Artemis missions will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.
Preparations for Next Moonwalk Simulations Underway (and Underwater)

NASA astronaut Jonny Kim is wrapping up his first mission aboard the International Space Station in early December. During his stay, Kim conducted scientific experiments and technology demonstrations to benefit humanity on Earth and advance NASA’s Artemis campaign in preparation for future human missions to Mars.
Here is a look at some of the science Kim completed during his mission:
Medical check-ups in microgravity
NASA
NASA astronaut Jonny Kim, a medical doctor, completed several routine medical exams while aboard the International Space Station. NASA flight surgeons and researchers monitor crew health using a variety of tools, including blood tests, eye exams, and ultrasounds.
Kim conducts an ultrasound of his eye in the left image. Eye exams are essential as long-duration spaceflight may cause changes to the eye’s structure and affect vision, a condition known as spaceflight associated neuro-ocular syndrome, or SANS. In the right image, Kim draws blood from a fellow crew member. These blood sample collections provide important insights into crew cartilage and bone health, cardiovascular function, inflammation, stress, immune function, and nutritional status.
NASA astronauts complete regular medical exams before, during, and after spaceflight to monitor astronaut health and develop better tools and measures for future human exploration missions to the Moon and Mars.
NASA astronaut Jonny Kim photographs dwarf tomato sprouts grown using a nutrient supplement instead of photosynthesis as part of a study on plant development and gene expression. The plants are given an acetate supplement as a secondary nutrition source, which could increase growth and result in better yields, all while using less power and fewer resources aboard the space station and future spacecraft.
NASA astronaut Jonny Kim uses a ham radio to speak with students on Earth via an educational program connecting students worldwide with astronauts aboard the International Space Station. Students can ask about life aboard the orbiting laboratory and the many experiments conducted in microgravity. This program encourages an interest in STEM (science, technology, engineering, and mathematics) and inspires the next generation of space explorers.
Secure and reliable data storage and transmission are essential to maintain the protection, accuracy, and accessibility of information. In this photo, NASA astronaut Jonny Kim displays research hardware that tests the viability of encoding, transmitting, and decoding encrypted information via DNA sequences. As part of this experiment, DNA with encrypted information is sequenced aboard the space station to determine the impact of the space environment on its stability. Using DNA to store and transmit data could reduce the weight and energy requirements compared to traditional methods used for long-duration space missions and Earth-based industries.
Future deep space exploration could rely on robotics remotely operated by humans. NASA astronaut Jonny Kim tests a technology demonstration that allows astronauts to remotely control robots on Earth from the International Space Station. Findings from this investigation could help fine-tune user-robot operating dynamics during future missions to the Moon, Mars, and beyond.
NASA astronaut Jonny Kim conducts an investigation to assess the effects of microgravity on bone marrow stem cells, including their ability to secrete proteins that form and dissolve bone. Bone loss, an age-related factor on Earth, is aggravated by weightlessness and is a health concern for astronauts. Researchers are evaluating whether blocking signals that cause loss could protect astronauts during long-duration spaceflights. The findings could also lead to preventative measures and treatments for bone loss caused by aging or disease on Earth.
NASA astronaut Jonny Kim tests new hardware installed to an existing crystallization facility that enables increased production of crystals and other commercially relevant materials, like golden nanospheres. These tiny, spherical gold particles have optical and electronic applications, and are biocompatible, making them useful for medication delivery and diagnostics. As part of this experiment aboard the space station, Kim attempted to process larger, more uniform golden nanospheres than those produced on the ground.
Some vitamins and nutrients in foods and supplements lose their potency during long-term storage, and insufficient intake of even a single nutrient can lead to diseases and other health issues. NASA astronaut Jonny Kim displays purple-pink production bags for an investigation aimed at producing nutrient-rich yogurt and kefir using bioengineered yeasts and probiotics. The unique color comes from a food-grade pH indicator that allows astronauts to visually monitor the fermentation process.
NASA astronaut Jonny Kim uses the Microgravity Science Glovebox to study how high-concentration protein fluids behave in microgravity. This study helps researchers develop more accurate models to predict the behavior of these complex fluids in various scenarios, which advances manufacturing processes in space and on Earth. It also can enable the development of next-generation medicines for treating cancers and other diseases.
On Sept. 28, 2025, NASA astronaut Jonny Kim photographed Hurricane Humberto from the International Space Station. Located at 250 miles above Earth, the orbiting laboratory’s unique orbit allows crew members to photograph the planet’s surface including hurricanes, dust storms, and fires. These images are used to document disasters and support first responders on the ground.
The Soyuz rocket launches to the International Space Station with Expedition 74 crew members: NASA astronaut Chris Williams, and Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev, on Thursday, Nov. 27, 2025, at the Baikonur Cosmodrome in Kazakhstan.

A crew of four research volunteers stepped inside NASA’s CHAPEA (Crew Health and Performance Exploration Analog) habitat on Oct. 19, marking the start of the agency’s second 378-day simulated Mars mission.
Ross Elder, Ellen Ellis, Matthew Montgomery, and James Spicer are living and working inside the roughly 1,700-square-foot 3D-printed habitat at the agency’s Johnson Space Center in Houston until Oct. 31, 2026.
“The information and lessons learned through CHAPEA will inform real-life mission planning, vehicle and surface habitat designs, and other resources NASA needs to support crew health and performance as we venture beyond low-Earth orbit,” said Sara Whiting, Human Research Program project scientist. “Through these lessons, NASA’s Human Research Program is reducing human health and performance risks of spaceflight to enable safe and successful crewed missions to the Moon, Mars, and beyond.”
The crew will face the challenges of a real Mars mission, and only leave to perform simulated “Marswalk” activities directly outside the habitat, wearing spacesuits, to traverse a simulated Mars environment filled with red sand. During these Marswalks, they will remain isolated within the building that houses CHAPEA at NASA Johnson.
“These crewmembers will help provide foundational data for mission planning and vehicle design and inform trades between resources, methods, and technologies that best support health and performance within the constraints of living on Mars,” said Grace Douglas, CHAPEA principal investigator. “The information gained from these simulated missions is critical to NASA’s goal of sending astronauts to explore Mars.”
During the year ahead, the crew will complete a variety of activities designed to replicate life and work on a long-duration mission on Mars, including high-tempo simulated Marswalks, robotic operations, habitat maintenance, physical exercise, and crop cultivation. The mission also aims to investigate how the crew adapts and responds to various environmental stressors that may arise during a real Martian mission, including limited access to resources, prolonged isolation, 22-minute communication delays, and equipment failures. Researchers will study how the team manages these conditions, which will inform future protocols and plans ahead of future crewed missions to Mars.
The first CHAPEA mission, which took place in the same habitat, concluded on July 6, 2024.

NASA’s Human Research Program
NASA’s Human Research Program pursues methods and technologies to support safe, productive human space travel. Through science conducted in laboratories, ground-based analogs, commercial missions, the International Space Station and Artemis missions, the program scrutinizes how spaceflight affects human bodies and behaviors. Such research drives the program’s quest to innovate ways that keep astronauts healthy and mission ready as human space exploration expands to the Moon, Mars, and beyond.
To see Earth from space is to be forever changed by the view. Since Alan Shepard became the first American to lay eyes on our home planet from above, countless NASA astronauts have described feeling awed by the astonishing sight and a profound shift in perspective that followed.
NASA astronaut Matthew Dominick points his camera through a cupola window as the International Space Station orbits 262 miles above the Atlantic Ocean off the coast of Africa.
NASA
This unique experience is known as the overview effect – a term coined in 1987 by space philosopher and author Frank White in a book of the same name. The phenomenon creates powerful changes in the way astronauts think about Earth and life and can be particularly strong for those who lived and worked aboard the International Space Station during its 25 years of continuous human presence. The orbiting laboratory’s cupola module, equipped with seven windows looking down on Earth, provides the perfect place for observation and reflection.
NASA astronaut Jessica Watkins is pictured looking out from the International Space Station’s “window to the world” – the cupola. Astronauts use the seven-windowed observation module to monitor the arrival of spacecrafts at the orbiting laboratory and view the Earth below.
NASA
As Artemis II Mission Specialist Christina Koch explained:
“The overview effect is when you’re looking through the cupola and you see the Earth as it exists with the whole universe in the background. You see the thin blue line of the atmosphere, and then when you’re on the dark side of the Earth, you actually see this very thin green line that shows you where the atmosphere is. What you realize is every single person that you know is sustained and inside of that green line and everything else outside of it is completely inhospitable. You don’t see borders, you don’t see religious lines, you don’t see political boundaries. All you see is Earth and you see that we are way more alike than we are different.”
Koch’s Artemis II crewmate, NASA astronaut Victor Glover, said the overview effect’s potency is closely tied to the “sea level effect” – humanity’s shared experience on Earth. “You come back to sea level, and then you have a choice,” he explained. “Are you going to try to live your life a little differently? Are you going to really choose to be a member of this community of Earth?”
NASA astronaut Don Pettit, Expedition 30 flight engineer, is pictured in a window of the cupola of the International Space Station, backdropped by Earth’s horizon and the blackness of space.
NASA
Many astronauts emphasize the importance of unity after experiencing the overview effect. “You see that it’s a single planet with a shared atmosphere. It’s our shared place in this universe,” said former NASA astronaut Bob Behnken. “I think that perspective, as we go through things like the pandemic or we see the challenges across our nation or across the world, we recognize that we all face them together.”
Seeing the Earth from space can also change their concept of home. Former NASA astronaut Nicole Stott recalls wanting to see her home state of Florida during her first mission to the International Space Station. “Finally, we were flying over Florida. I wanted to go to the window and see it, and then realized somewhere down the line that I wasn’t looking at Florida that same way anymore,” she said. “I still wanted to see Florida, but Florida had just become this special part of home, which is Earth. We’re all earthlings.”
The sun shines above Earth’s horizon as the space station orbits 264 miles above the Canadian province of Quebec.
NASA
For some astronauts, their perspective shift inspired them to make changes on the ground. “I think if you’re not a conservationist before you go to space, you’re at least partly a conservationist when you come back. Because when you see how thin that atmosphere is, that protective layer that we have here, you think, wow, we really have to take care of this because it does look so fragile from space,” said retired NASA astronaut Mike Foreman.
Others hope to share the overview effect with more people. “That perspective helps you grow. It has really inspired me to try to get more people this experience and to get a permanent foothold in the stars for our species,” said former NASA astronaut Jack Fischer. “I want to do everything I possibly can to help the human species, humanity as a whole, go further and grow and evolve like I know they’re capable of.”

Future crews to the orbiting laboratory can look forward to a similar experience. “In that instant, when you’re overwhelmed with that vista, when your eyes see nothing but the beauty of the Earth – every single crew member that I brought in [the cupola] for that exposure, cried,” said retired NASA astronaut T.J. Creamer. “It is heart stopping. It is soul pounding. It is breathtaking.”

NASA Opens 2026 Human Lander Challenge for Life Support Systems, More
NASA’s 2026 Human Lander Challenge is seeking ideas from college and university students to help evolve and transform technologies for life support and environmental control systems. These systems are critical for sustainable, long-duration human spaceflight missions to the Moon, Mars, and beyond.
The Human Lander Challenge supports NASA’s efforts to foster innovative solutions to a variety of areas for NASA’s long-duration human spaceflight plans at the Moon under the Artemis campaign. The Human Lander Challenge is sponsored by the Human Landing System Program within the Exploration Systems Development Mission Directorate.
The 2026 competition invites undergraduate and graduate-level teams based in the U.S., along with their faculty advisors, to develop innovative, systems-level solutions to improve aspects for a lander’s ECLSS (Environmental Control and Life Support System) performance. These air, water, and waste systems provide vital life support so future Artemis astronauts can live and work safely and effectively on the Moon during crewed missions.
Each proposed solution should focus on one of the following long-duration ECLSS subtopics:
Noise suppression and control
Sensor reduction in hardware health monitoring systems
Potable water dispenser
Fluid transfer between surface assets on the Moon and Mars
“A robust ECLSS transforms a spacecraft like a lander from just hardware into a livable environment, providing breathable air, clean water, and safe conditions for astronauts as they explore the Moon,” said Kevin Gutierrez, acting office manager for the Human Landing Systems Missions Systems Management Office at NASA Marshall. “Without ECLSS we can’t sustain human presence on the Moon or take the next steps toward Mars. The subtopics in the 2026 Human Lander Challenge reflect opportunities for students to support the future of human spaceflight.”
2026 Competition
Teams should submit a non-binding notice of intent by Monday, Oct. 20, if they intend to participate. Proposal packages are due March 4, 2026.
Based on proposal package evaluations in Phase 1, up to 12 finalist teams will be selected to receive a $9,000 stipend and advance to Phase 2 of the competition, which includes a final design review near NASA’s Marshall Space Flight Center in Huntsville, Alabama, June 23-25, 2026. The top three placing teams from Phase 2 will share a total prize of $18,000.
Landers are in development by SpaceX and Blue Origin as transportation systems that will safely ferry astronauts from lunar orbit to the Moon’s surface and back for the agency’s Artemis campaign. NASA Marshall manages the Human Landing System Program.
The challenge is administered by the National Institute of Aerospace on behalf of the agency.
Through the agency’s Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.

In 2016, NASA awarded a Commercial Resupply Services-2 contract to Sierra Space, formerly part of Sierra Nevada Corporation, to resupply the International Space Station with its Dream Chaser spaceplane and companion Shooting Star cargo module. As part of its contract, Sierra Space was awarded a minimum seven flights, and the agency previously issued firm-fixed price task orders for four Dream Chaser resupply missions based on the needs of the space station.
After a thorough evaluation, NASA and Sierra Space have mutually agreed to modify the contract as the company determined Dream Chaser development is best served by a free flight demonstration, targeted in late 2026. Sierra Space will continue providing insight to NASA into the development of Dream Chaser, including through the flight demonstration. NASA will provide minimal support through the remainder of the development and the flight demonstration. As part of the modification, NASA is no longer obligated for a specific number of resupply missions; however, the agency may order Dream Chaser resupply flights to the space station from Sierra Space following a successful free flight as part of its current contract.
“Development of new space transportation systems is difficult and can take longer than what’s originally planned. The ability to perform a flight demonstration can be a key enabler in a spacecraft’s development and readiness, as well as offering greater flexibility for NASA and Sierra Space,” said Dana Weigel, manager of NASA’s International Space Station Program. “As NASA and its partners look toward space station deorbit in 2030, this mutually agreed to decision enables testing and verification to continue on Dream Chaser, as well as demonstrating the capabilities of the spaceplane for future resupply missions in low Earth orbit.”
NASA, and its commercial and international partners, will continue to supply the orbital complex with critical science, supplies, and hardware as the agency prepares to transition to commercial space stations in low Earth orbit. NASA continues to work with a variety of private companies to develop a competitive, space industrial base for cargo services, which will be needed for future commercial space stations. With a strong economy in low Earth orbit, NASA will be one of many customers of private industry as the agency explores the Moon under the Artemis campaign and Mars along with commercial and international partners.
