NASA has selected 34 global volunteers to track the Orion spacecraft during the crewed Artemis II mission’s journey around the Moon.

The Artemis II test flight will launch NASA’s Space Launch System (SLS) rocket, carrying the Orion spacecraft and a crew of four astronauts, on a mission into deep space. The agency’s second mission in the Artemis campaign is a key step in NASA’s path toward establishing a long-term presence at the Moon and confirming the systems needed to support future lunar surface exploration and paving the way for the first crewed mission to Mars.

While NASA’s Near Space Network and Deep Space Network, coordinated by the agency’s SCaN (Space Communication and Navigation) program , will provide primary communications and tracking services to support Orion’s launch, journey around the Moon, and return to Earth, participants selected from a request for proposals published in August 2025, comprised of established commercial service providers, members of academia, and individual amateur radio enthusiasts will use their respective equipment to passively track radio waves transmitted by Orion during its approximately 10-day journey.

“The Artemis II tracking opportunity is a real step toward SCaN’s commercial-first vision. By inviting external organizations to demonstrate their capabilities during a human spaceflight mission, we’re strengthening the marketplace we’ll rely on as we explore farther into the solar system,” said Kevin Coggins, deputy associate administrator for SCaN at NASA Headquarters in Washington. “This isn’t about tracking one mission, but about building a resilient, public-private ecosystem that will support the Golden Age of innovation and exploration.”

These volunteers will submit their data to NASA for analysis, helping the agency better assess the broader aerospace community’s tracking capabilities and identify ways to augment future Moon and Mars mission support. There are no funds exchanged as a part of this collaborative effort.

This initiative builds on a previous effort in which 10 volunteers successfully tracked the Orion spacecraft during Artemis I in 2022. That campaign produced valuable data and lessons learned, including implementation, formatting, and data quality variations for Consultative Committee for Space Data Systems, which develops communications and data standards for spaceflight. To address these findings, SCaN now requires that all tracking data submitted for Artemis II comply with its data system standards.

Compared to the previous opportunity, public interest in tracking the Artemis II mission has increased. About 47 ground assets spanning 14 different countries will be used for to track the spacecraft during its journey around the Moon.

Listen to this audio excerpt from Dustin Gohmert, Orion Crew Survival System (OCSS) manager:

During NASA’s Artemis II mission around the Moon, the astronauts inside the Orion spacecraft will be wearing specialized pressure suits designed to protect them throughout their journey. At NASA’s Johnson Space Center in Houston, Dustin Gohmert leads the team responsible for these suits, known as the Orion Crew Survival System (OCSS).

“We work with the crew to say, ‘Here’s this design concept we have. How does this really work in the spaceflight environment?’” Gohmert said. “As we evolve the design, we take the crew’s input and we adapt the suit over time to take into account not only the desire we have for safety, but the real-world impacts that it has.”

The suits will protect astronauts on launch day, throughout high-risk parts of missions near the Moon, during the high-speed return to Earth, and in emergency situations if such events arise. The OCSS suits are engineered to sustain life for up to six days in the event of an emergency, and can provide the astronauts oxygen, hydration, food, and waste management needed on their way back to Earth.

“In an emergency, you’re essentially living in a personal spacecraft that’s only an inch bigger than your body,” Gohmert said. “That’s the reality of survival in space.”

Gohmert’s team in the Orion Crew Survival Systems Lab manages every phase of the suits, including processing, designing, qualifying, and testing them for the mission, as well as integrating them with the Orion spacecraft. Their work addresses engineering challenges, such as how much internal pressure the suit can safely maintain and for how long.

The team custom-builds each suit to fit the anatomy of the astronauts. Crew members undergo detailed sizing and multiple fit checks to ensure precision, and their feedback is a key part of the design evolution and refinement of the suit.

After earning his bachelor’s in mechanical engineering from the University of Texas at San Antonio and his master’s in engineering from the University of Texas at Austin, Gohmert joined United Space Alliance before becoming a NASA civil servant. He worked through the end of the Space Shuttle Program and later transitioned to Orion. Working on the suit throughout his career has been both technically challenging and a deeply personal responsibility.

As NASA prepares to explore deep space with Artemis II, Gohmert’s role will play a part in safely sending crew members around the Moon and returning them home.

“I was born after the last Moon landing,” he said. “To actually be a part of the next round is kind of overwhelming. It’s awe-inspiring in every possible way.”

As America approaches its 250th anniversary of declaring independence, NASA’s Artemis II mission will carry a host of mementos that reflect the nation’s long tradition of exploration, innovation, and leadership in its official flight kit. The items will fly aboard the Orion spacecraft, launched on top of the Space Launch System (SLS) rocket, as it carries four astronauts around the Moon on the first crewed test flight of the agency’s Artemis campaign.

“Historical artifacts flying aboard Artemis II reflect the long arc of American exploration and the generations of innovators who made this moment possible,” said NASA Administrator Jared Isaacman. “This mission will bring together pieces of our earliest achievements in aviation, defining moments from human spaceflight, and symbols of where we’re headed next. During America’s 250th anniversary, Orion will carry astronauts around the Moon while also carrying our history forward into the next chapter beyond Earth.”

Selected to honor America’s historic achievements in space, inspire the next generation of explorers, and reinforce U.S. leadership through international cooperation in science and education, the mementos continue a proud tradition carried forward from Artemis I and earlier human spaceflight missions. Together, they highlight the freedom and innovation that have unlocked the Golden Age of human space exploration.

A 1-inch by-1-inch swatch of muslin fabric from the original Wright Flyer the Wright Brothers used to make the first powered flight in 1903 will be flying aboard Artemis II, lent by the Smithsonian’s National Air and Space Museum. A smaller square cut of the swatch previously flew aboard space shuttle Discovery on STS-51D in 1985 and will make its second journey into space. After the mission, the fabric will be reunited with two other 1903 Wright Flyer swatches at the museum, celebrating the nation’s history and innovation in aviation.

Also flying aboard the Artemis II mission will be a 13-by-8-inch American flag, which flew with the first shuttle mission, STS-1, the final shuttle mission, STS-135, and NASA’s first crewed test flight of SpaceX’s Crew Dragon spacecraft, SpaceX Demo-2.

A flag that was set to fly on NASA’s Apollo 18 mission is included in the flight kit and will make its premiere flight with Orion. The flag serves as a powerful emblem of America’s renewed commitment to human exploration of the Moon, while honoring the legacy of the Apollo pioneers who first blazed the trail.

Orion also will carry a copy of a 4-by-5-inch negative of a photo from the Ranger 7 mission, the first U.S. mission to successfully make contact with the lunar surface. NASA’s Jet Propulsion Laboratory in California managed the Ranger series of spacecraft, built to help identify safe Moon landing sites for Apollo astronauts. The photo represents a major turning point in the race to the Moon that will be echoed today through the success of Artemis.

On Artemis I, a variety of tree seeds flew and were distributed to educational organizations and teachers after the mission, following in the footsteps of tree seeds flown aboard the Apollo 14 mission sprouted into “Moon Trees” after being returned to Earth. The seeds have since taken root at 236 locations across the U.S. to become their own Artemis I Moon Trees. Soil samples collected from the base of established Artemis I Moon Trees planted at NASA’s 10 centers will fly aboard Artemis II, representing the full cycle of exploration: launch, flight, growth, and return to space again. The CSA (Canadian Space Agency) will fly various tree seeds in the kit with the intention of distributing them after the mission.

Also included in the kit will be an SD card including the millions of names of those who participated in the “Send Your Name to Space” campaign, bringing the public along on this journey. The kit will include a variety of flags, patches, and pins to be distributed after the mission to stakeholders and employees who contributed to the flight. 

Additionally, NASA has included items from several of its partners in the kit. Stickers and patches from CSA will fly, and ESA (European Space Agency) will fly a flag in the kit for distribution after the mission, marking NASA’s international collaboration with other space agencies through Artemis. Orion’s European Service Module, the powerhouse of the spacecraft, is provided by ESA.

Carrying mementos on the NASA spacecraft has been a tradition since the 1960s, one that was continued on Artemis I, the first uncrewed test flight of Orion and the SLS. During this mission, Orion carried a symbolic flight kit including historical artifacts, from Apollo missions STEM, or science, technology, engineering, and math, items, digitized student essays and teacher pledges, and more.

The official flight kit for Artemis II, which contains about 10 pounds of mementos in total, augments important scientific research  aboard Orion.

Listen to this audio excerpt from Jacki Mahaffey, Artemis II chief training officer:

When the Artemis II crew travels around the Moon aboard the Orion spacecraft, they will have spent countless hours training for their lunar mission, and Jacki Mahaffey will have played a role in preparing them for their journey.

As the Artemis II chief training officer at NASA’s Johnson Space Center in Houston, Mahaffey manages the planning, development, and implementation of the astronauts’ training and integrated simulations. Her job is to ensure that when the Artemis II crew travels around the Moon inside Orion, the astronauts and flight controllers are ready for every moment — expected and unexpected.

The Artemis II crew began their rigorous training in 2023, but the work of Mahaffey and her team started long before that. Years before the training began, her team gathered the experts on how to operate the different aspects of Orion, and what the crew will need to know to execute their mission.

“One of my favorite moments from that process was when we all got together in one room, and everyone brought a piece of paper for every single lesson or training event that they expected to do with the crew,” Mahaffey said. “And we laid the entire thing out to figure out what’s the most logical order to put all of this training in, to help build that big picture for the crew.”

Training for Artemis II began shortly after the crew was announced, with Mahaffey and her team introducing the astronauts to Orion’s systems and operational basics. Once the necessary simulators and mockups were ready, the crew transitioned into hands-on training to build familiarity with their spacecraft.

At Johnson, Mahaffey’s team utilizes a range of specialized facilities, including the Space Vehicle Mockup Facility, where astronauts rehearse living and working inside the Orion mockup; the Orion Mission Simulator, which replicates flight software and displays; and the Neutral Buoyancy Laboratory, where the crew practices water survival techniques for post-splashdown scenarios.

“We try to simulate as much as we can here on Earth,” said Mahaffey. “But we still have gravity, so we rely on the crew’s experience to imagine how they’ll use the space in microgravity”

Three of the four Artemis II astronauts have flown in space before, and Mahaffey sees their experience as a powerful asset. They bring insights that shape procedures and training plans, and they learn from each other’s unique problem-solving styles.

“They are teaching us back about how to have that crew perspective of working in space and the things that are going to matter most,” she said.

Mahaffey’s journey began with a love for engineering and a role as a flight controller in Johnson’s Mission Control Center. She found joy in training others and eventually transitioned into a full-time training role. Now, she leads a team of about 100 contributors, all working to prepare the crew for their historic mission.

“I didn’t start out wanting to be a trainer — I studied engineering because I loved physics and math,” she said. “But as the job shifted toward applying that engineering knowledge, communicating, and planning how to operate a spacecraft, the natural next step was teaching others.”

For Mahaffey, Artemis is a bridge connecting her family’s legacy with the future of space exploration. Her grandfather worked on control systems for Apollo, and she sees her work as a continuation of that story, now with more advanced technology and new frontiers. 

“We’re doing some of the same things Apollo did, but expanding on them,” she said. “We’re learning more about the Moon, our Earth’s history, and how we’ll get to Mars.” 

Her role during Artemis II also includes serving as an Artemis capcom, short for capsule communicator, the position in mission control that directly communicates with the crew members. Mahaffey plans to work the entry shift for Artemis II — helping to guide the crew to splashdown and ensuring their safe recovery. The moment will be a culmination of her entire team’s hard work. 

“I’ll feel good when the recovery forces report that the hatch is open,” Mahaffey said. “That moment will be incredible.” 

Listen to this audio excerpt from Jen Madsen and Trey Perryman, leads of the Orion Mission Evaluation Room for the Artemis II mission:

During NASA’s Artemis II mission, Jen Madsen and Trey Perryman will be leading a team monitoring the Orion spacecraft as it carries four astronauts around the Moon. The team works in the Orion Mission Evaluation Room where they will monitor and analyze Orion’s systems and performance in real time to help ensure crew safety and mission success.

As the leaders of the Orion Mission Evaluation Room located inside the Mission Control Center at NASA’s Johnson Space Center in Houston, Madsen and Perryman are responsible for ensuring that the dozens of NASA, Lockheed Martin, ESA (European Space Agency), and Airbus expert engineers that staff the room’s consoles are ready for Artemis II.

The flight control team operating Orion from mission control’s White Flight Control Room will rely on the Mission Evaluation Room’s crucial findings to help with unexpected spacecraft behaviors that may arise and help analyze Orion’s performance data during the mission.

With crew aboard Orion, Artemis II brings new challenges, new opportunities, and a new space in mission control for the Orion Mission Evaluation Room. More spacecraft systems will be put to the test, requiring more evaluation room expertise and new consoles to monitor systems not previously flown, like life support.

“There’s loads of excitement — for the new capabilities, the mission, and having a new, wonderful space to operate in,” said Perryman.

Besides leading the Mission Evaluation Room, Perryman is also the lead for Orion Mission and Systems Integration, and Madsen is deputy manager for Orion’s Avionics, Power, and Software. Their co-leadership styles complement each other — Perryman leads with energy and team spirit, while Madsen brings a steadiness and structure.

“We balance each other out,” Madsen said. “And that balance is reflected in our team.”

For Perryman, a former flight controller with a background in space shuttle and space station operations, the MER represents the culmination of a career in human spaceflight that’s personal.

“I couldn’t imagine being anywhere else right now,” Perryman said. “My wife and I have four boys, and my boys are very excited about Artemis…that’s meaningful to me. And they like seeing a father who’s really connected to this mission.”

Madsen began her NASA career in engineering, designing and simulating Orion’s guidance, navigation, and control systems early on in the program.

For both leaders, the Artemis II mission is more than technical. With crew flying aboard the spacecraft, it’s deeply human.

“I do feel an extra sense of importance and mindfulness about what we’re doing in this building,” Perryman said,  “making sure — specifically in the Orion MER — that we understand how the vehicle supports the crew, because it is so important to return them home safely.”

“We all feel like Reid, Victor, Christina, and Jeremy are part of the Orion family,” Madsen said. “When we have discussions about risk, from design all the way through operations, we’re thinking about our friends aboard the spacecraft.”

For most, getting into a car is a task that can be done without assistance. Yet for those whose destination is the Moon, the process of getting inside and secured – in this case, in NASA’s Orion spacecraft – requires help. That’s the role of the Artemis closeout crew.

Trained to support Artemis II and future Moon missions, the five closeout crew members will be the last people to see NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen before their lunar journey.

The Artemis II closeout team consists of a lead, Taylor Hose; an astronaut support person, astronaut Andre Douglas; one technician specially trained on Orion crew survival system spacesuits, Bill Owens; and two Orion technicians, Christian Warriner and Ricky Ebaugh.

Think of them like a pit crew for car races.

When the astronauts arrive on launch day at Launch Complex 39B at NASA’s Kennedy Space Center in Florida, the closeout crew will already be in place. First, the team will help the astronauts don their helmets and gloves before entering the Orion spacecraft.

Once inside, Owens and Douglas will assist each crew member with buckling up – except instead of using just one seatbelt like in a car, the crew needs several more intricate connections. Each seat includes five straps to secure the astronauts inside the crew module and several additional connections to the environmental control and life support systems and communications system aboard.

After the astronauts are secured, the hatch technicians will begin closing the spacecraft hatch. Unlike a car door that easily opens and closes with the pull of a handle, Orion’s hatch requires more effort to securely close.

“The hatch is pneumatically driven so we have to have air lines hooked up to it, and we need the help of the ground support system to close it,” said Hose.

On launch day, it will take about four hours for the crew to get situated inside Orion and for the closeout process, including buttoning up both the crew module hatch and an exterior launch abort system hatch, to be complete. Even a single strand of hair inside the hatch doors could potentially pose issues with closing either hatch, so the process is carefully done.

“We have a lot of work to do with the seals alone – greasing, cleaning, taking the hatch cover off – and then we get into crew module hatch closure,” Hose said. “So after latching the hatch, we take window covers off, install thermal protection panels, and remove the purge barrier in between the vehicle and the ogive panels, which help protect the crew module during launch and ascent.”

The team then closes the launch abort system hatch and finishes final preparations before launch. Following the abort system hatch closure, the closeout crew departs the launch pad but stays nearby in case they need to return for any reason.

After launch, several team members will head to San Diego, to help with post-splashdown efforts once the mission concludes.

As part of a Golden Age of innovation and exploration, the Artemis II test flight is the first crewed flight under NASA’s Artemis campaign. It is another step toward new U.S.-crewed missions on the Moon’s surface that will help the agency prepare to send the first astronauts – Americans – to Mars.

NASA’s launch and mission teams, along with the Artemis II crew, completed a key test Dec. 20, a countdown demonstration test, ahead of the Artemis II flight around the Moon early next year. The astronauts, supported by launch and flight control teams, dressed in their launch and entry suits, boarded their spacecraft on top of its towering rocket at the agency’s Kennedy Space Center in Florida to validate their launch date timeline.

Winding the clock down to a point just before liftoff, the rehearsal enabled NASA teams to practice the exact steps teams will take as they move toward launch of the test flight.

While launch teams in the firing rooms of Kennedy’s Launch Control Center ran through procedures just as they would on launch day, the Artemis II crew members – NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen – donned their Orion crew survival system spacesuits in the Astronaut Crew Quarters inside Kennedy’s Neil A. Armstrong Operations and Checkout Building.

Once suited, the crew made the same walk taken by Gemini, Apollo, space shuttle, and Commercial Crew Program astronauts launching from Florida’s Space Coast during the last six decades. Through the suit-up room, down the hallway, and after a quick ride on an elevator, the Artemis II crew exited the building through the double doors featuring dozens of human spaceflight mission patch stickers.

The Artemis astronaut van waited outside to take the crew members to their SLS (Space Launch System) rocket. On the actual launch day, the four astronauts will complete a 20-minute ride to Kennedy’s Launch Complex 39B ahead of liftoff. But, for the countdown test the destination was High Bay 3 of Kennedy’s Vehicle Assembly Building, where the Artemis II Moon rocket is undergoing final processing and checkouts before rolling out to the launch pad. A convoy of support vehicles, as well as Artemis II backup crew members, NASA astronaut Andre Douglas and CSA astronaut Jenni Gibbons, escorted the crew to its destination.

After a short trip to the building, the flight crew rode the mobile launcher’s elevator up nearly 300 feet to the crew access arm and the White Room, the enclosed area where the crew enters the spacecraft. The closeout crew, whose job it is to ensure the flight crew enters the spacecraft without issue, helped the astronauts enter Orion, which they have named Integrity. The closeout team assisted the astronauts by strapping them into their seats and closed the hatch once all closeout operations were completed. With the crew secured in Orion, teams conducted suit leak and communications checks, just as they will on launch day.

Throughout the testing, teams ran through the final 5.5 hours of launch day procedures, completing the countdown test about 30 seconds before what will be the time of liftoff on launch day. As they may encounter on launch day, teams navigated through several real-time issues, including audio communications and environmental control and life support systems closeout activities during the test. All objectives were met, and the countdown demonstration provided a valuable opportunity to conduct operations in a day-of-launch configuration to minimize first-time learnings on launch day.

Although Artemis II teams have performed parts of the launch countdown testing previously, this test was the first full end-to-end rundown with the crew and Orion in the launch configuration. The crew will participate in additional countdown testing after the rocket arrives to the launchpad, focusing on emergency operations.

As part of a Golden Age of innovation and exploration, the Artemis II test flight is the first crewed mission under NASA’s Artemis campaign. It is another step toward new U.S.-crewed missions on the Moon’s surface that will help the agency prepare to land American astronauts on Mars.

Listen to this audio excerpt from Grace Lauderdale, exploration project manager for the Training Systems Office at NASA Johnson:

In preparation for their mission around the Moon inside NASA’s Orion spacecraft, the Artemis II crew will spend countless hours training inside the Orion Mission Simulator. The simulator replicates what the crew will experience inside the spacecraft and allows the astronauts and flight controllers to rehearse every phase of the mission.

As the exploration project manager for the Training Systems Office at Johnson, Grace Lauderdale leads the team that develops and operates the Orion Mission Simulator at NASA’s Johnson Space Center in Houston, playing a key role in making sure astronauts and flight control teams are ready for the first crewed mission of the Artemis campaign.

The simulator is more than a mock-up. It connects directly to Johnson’s Mission Control Center, sending real-time data, audio, and video — just like the spacecraft will during flight. That means the flight control team trains in parallel, seeing and hearing exactly what they would throughout the mission.

“One of our major goals is to make the data they see on their displays look like the real vehicle,” Lauderdale said. “We also simulate the near space and deep space networks, including all the communication delays. It’s all about realism.”

That realism is powered by a complex software system developed in collaboration with partners like Lockheed Martin. Lauderdale’s team works behind the scenes to ensure the simulator runs smoothly — writing code, troubleshooting issues, and even creating custom malfunctions to challenge the crew during training.

To prepare astronauts for the unexpected, instructors work with Lauderdale’s team to simulate problems that could occur during the mission, some of which require creative solutions.

“There are times when the instructors will ask for malfunctions or capabilities that the sim doesn’t automatically do,” she said. “Part of our role is to come up with ways to make that happen.”

Her team plans, develops, and executes training scenarios in the Orion Mission Simulator across multiple Artemis missions, often simultaneously. “Currently, we’re planning for future crewed missions, developing Artemis III, and executing Artemis II,” she said.

The work is demanding, but deeply personal, according to Lauderdale.

That passion shows in her leadership. Her team often works nights, weekends, and holidays to ensure the simulator is ready. During a recent 30-hour simulation, they spent days preparing, fixing memory issues, and ensuring the system wouldn’t crash. It didn’t.

“I’m very proud of my team,” she said. “They’ve put in countless hours of work to make sure this simulator reacts exactly as it would in the real mission.”

For Lauderdale, helping send astronauts around the Moon isn’t just a job—it’s a dream realized.

“Being part of getting us back to the Moon is very personal to me,” she said. “And I’m proud to be part of the team that will help get our astronauts there.”

Teams at NASA’s Kennedy Space Center in Florida spent 2025 preparing the launch vehicle and its powerhouse SLS (Space Launch System) rocket to launch four astronauts around the Moon for Artemis II in early 2026. The center also celebrated milestones by conducting science experiments at the International Space Station to studying the Sun’s solar wind impacts on Earth to traveling to Mars in hopes of one day exploring the Red Planet in person.

Johnson-Built Mars Hardware on Display at the Smithsonian 

A piece of NASA Johnson Space Center’s Mars legacy has landed at the Smithsonian National Air and Space Museum in Washington, D.C. 

Nearly 10 years in the making, the Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals (SHERLOC) calibration target—built by Johnson’s ARES Division with partners at NASA’s Jet Propulsion Laboratory and Amentum—now has a permanent place in the museum’s Futures in Space gallery.  

The palm-sized device is displayed beside an R2-D2 replica, connecting the wonder of space travel with the inspiration of seeing real flight hardware up close. 

The calibration target, still in use aboard NASA’s Perseverance rover after more than four years of operations in Jezero Crater, Mars, helps keep SHERLOC’s laser, cameras, and spectrometers precisely tuned as it searches for ancient signs of life on Mars. Mounted on the rover’s front, the target carries 10 known samples so engineers can check SHERLOC’s performance during routine operations. 

Trevor Graff, an ARES scientist who conceived the idea and led the team that designed and built SHERLOC’s calibration device, said the project highlights the unique role of geology in space exploration. “What excites me most is the practical application of geology—where science enables exploration and exploration enables science,” he said.  

SHERLOC itself sits on the rover’s seven-foot robotic arm and combines a laser, camera, and chemical analyzers to look for signs that water once altered the Martian surface, potentially revealing evidence of past microscopic life. Several calibration targets are made from spacesuit material samples, allowing Johnson scientists to study how fabrics endure the harsh Martian environment to protect future explorers.
