NASA announces its 2025 astronaut class with historic gender diversity and broad expertise, preparing for lunar and Mars exploration.
NASA’s recent announcement of its 2025 astronaut class marks a pivotal moment in the evolution of human spaceflight. With the introduction of ten new astronaut candidates, six women and four men, NASA is not only making history with its most diverse class to date, but also signaling its commitment to preparing for the next generation of lunar and Mars missions. This selection comes at a time of rapid change within both NASA and the broader space industry, as commercial partnerships and international collaborations reshape the landscape of crewed space exploration.
The significance of this new class extends beyond its demographic milestones. These candidates were chosen from a pool of more than 8,000 applicants, reflecting the enduring prestige and competitiveness of NASA’s astronaut program. Over the next two years, these individuals will undergo intensive Training, equipping them with the skills needed to operate in some of the most challenging environments ever faced by humans. Their journey is emblematic of the broader shifts in space exploration, where diversity, interdisciplinary expertise, and adaptability are increasingly vital.
This article explores the historical context of NASA’s astronaut selection, details the backgrounds and training of the 2025 class, and examines the broader implications for the future of space exploration. Through analysis of official statements, expert opinions, and institutional data, we provide a comprehensive overview of what this new class represents for NASA and for humanity’s aspirations beyond Earth.
NASA’s astronaut selection process has evolved substantially since the agency’s founding. The original Mercury Seven, selected in 1959, were all white male military test pilots, chosen under strict physical and experiential criteria tailored to the cramped and hazardous conditions of early space capsules. These early requirements included height restrictions and extensive flight experience, reflecting both technological limitations and the prevailing social norms of the era.
As NASA’s mission portfolio expanded, so too did the backgrounds of its astronauts. The inclusion of scientist-astronauts in the 1960s, such as geologists and medical doctors, was initially controversial among the traditional pilot corps. However, their contributions, most notably during the Apollo 17 mission, demonstrated the value of interdisciplinary expertise. Over the decades, NASA’s astronaut corps has become increasingly diverse, with candidates now selected from fields including engineering, medicine, biology, geology, and more.
By 2025, NASA had selected 370 astronauts in total, reflecting a gradual but persistent shift toward greater inclusion and broader skill sets. The agency’s selection cycle, typically every four years, is designed to meet the evolving needs of missions ranging from International Space Station (ISS) operations to lunar and deep space exploration under the Artemis program. This evolution mirrors broader societal changes and the growing complexity of human spaceflight.
The announcement of the 2025 astronaut class stands out as a landmark in NASA’s history, marking the first time that women outnumber men in a selection group. This milestone is especially significant given the underrepresentation of women in previous astronaut cohorts. According to NASA, women now make up approximately 37 percent of the active astronaut corps, a substantial increase from the all-male classes of the past.
The 2025 class was selected from over 8,000 applicants, a testament to the enduring allure of the astronaut profession and the high standards maintained by NASA’s selection board. The group’s diversity extends beyond gender: it includes pilots with high-performance aircraft experience, a biomedical engineer, an anesthesiologist, a geologist, and a former SpaceX launch director. This range of expertise reflects the multifaceted challenges of modern space missions, which demand not only technical proficiency but also scientific, medical, and operational acumen. Notably, Anna Menon, one of the new candidates, brings private spaceflight experience from her time on the Polaris Dawn mission and her work with SpaceX. Her selection highlights the increasing integration of commercial spaceflight experience within NASA’s ranks. The class also features two Purdue University alumni, reinforcing the university’s reputation as a leading incubator of astronaut talent.
“One of these 10 could actually be one of the first Americans to put their boots on the Mars surface, which is very, very cool.”, Sean Duffy, NASA Acting Administrator
Becoming a NASA astronaut candidate is only the beginning. Over the next two years, these individuals will undergo a demanding training program at the Johnson Space Center in Houston. The curriculum is designed to prepare them for the physical, technical, and psychological challenges of spaceflight. Training encompasses basic and advanced instruction in spacecraft systems, orbital mechanics, Earth observations, and space physiology.
Candidates must also master International Space Station operations, survival skills for both land and water, and proficiency in the Russian language, reflecting the international nature of ISS crews. Pilots receive additional flight training on NASA’s T-38 jets, while all candidates participate in simulated spacewalks at the Neutral Buoyancy Laboratory, a massive pool that provides a realistic environment for practicing extravehicular activities.
The final phase of training is mission-specific, focusing on the particular systems, experiments, and emergency procedures relevant to upcoming flights. Increasingly, NASA is incorporating virtual reality and advanced simulation technologies to prepare astronauts for the realities of space environments. The training infrastructure, including the Astronaut Training Facility and Neutral Buoyancy Laboratory, represents decades of investment in human spaceflight capabilities.
“The Neutral Buoyancy Laboratory, with its 6.2 million gallons of water, is essential for simulating weightlessness and preparing astronauts for spacewalks.”, NASA Training Documentation
Analysis of NASA’s selection data reveals persistent trends and evolving priorities. Research indicates that the optimal age for astronaut selection is just before 40, with the average age of selectees in 2013 being 36.6 years. Applicants outside the 30–45 age range are statistically less likely to be selected, reflecting the physical and career trajectory demands of the profession.
Women in the astronaut corps tend to be younger on average, have fewer children, and are less likely to have military backgrounds compared to their male counterparts. The 2025 class’s gender balance is a significant departure from historical norms and may signal a broader commitment to addressing gender disparities in STEM and space professions.
NASA’s selection process is not only about individual excellence but also about building effective teams. April Jordan, who oversees astronaut selection, emphasizes that the board looks for candidates who can complement each other’s skills and work cohesively under pressure. This team-oriented approach is increasingly important as missions become longer, more complex, and more reliant on international and commercial Partnerships.
“We’re not just selecting individuals; we’re building teams that can succeed in the most challenging environments imaginable.”, April Jordan, NASA Astronaut Selection Lead
NASA’s Investments in astronaut training infrastructure is substantial. The Johnson Space Center’s Astronaut Training Facility has been the backbone of U.S. astronaut preparation since 1980, housing full-scale mockups of the ISS, Orion spacecraft, and advanced robotics projects. The Neutral Buoyancy Laboratory, one of the world’s largest indoor pools, allows astronauts to practice spacewalks in simulated weightlessness. These facilities are continually updated to reflect new mission requirements, such as commercial crew vehicles and lunar landers. The training environment is designed to replicate space conditions as closely as possible, providing astronauts with hands-on experience in systems management, emergency procedures, and teamwork under pressure.
Financially, NASA’s fiscal year 2025 budget request includes over $100 million dedicated to human spaceflight operations and health, underscoring the agency’s recognition of the critical role that training and preparation play in mission success.
The 2025 astronaut class will operate in a space environment increasingly defined by commercial partnerships and international cooperation. SpaceX’s Crew Dragon spacecraft and Axiom Space’s private astronaut missions are now integral to NASA’s human spaceflight operations. Candidates like Anna Menon, who bring commercial sector experience, exemplify this new paradigm.
International collaboration is also central to NASA’s future plans. The Artemis II mission, scheduled for 2026, will include a Canadian astronaut and lay the groundwork for further multinational lunar exploration. The ISS remains a model of international partnership, and future lunar and Mars missions are expected to involve even broader coalitions of space agencies and commercial entities.
As more countries and private companies seek access to space, NASA’s astronaut training programs are likely to become even more interdisciplinary and globally integrated. This trend will require ongoing adaptation in both selection criteria and training methodologies.
NASA’s 2025 astronaut class represents a new chapter in the story of human space exploration. With its unprecedented gender balance, diverse professional backgrounds, and integration of commercial spaceflight experience, this group embodies the qualities needed for the challenges ahead. Their selection and training reflect decades of institutional learning and a forward-looking approach to building teams capable of succeeding in the most demanding environments known to humanity.
As these ten candidates embark on their training, they not only prepare for missions to the ISS, Moon, and potentially Mars, but also set a standard for future astronaut classes. Their journey will be watched closely as a barometer of NASA’s ability to adapt to the changing landscape of space exploration, where diversity, collaboration, and innovation are more important than ever.

Sodern Opens First US Facility in Colorado for Star Tracker Production
Sodern launches its first US industrial subsidiary in Colorado, producing Auriga™ star trackers and expanding in the US aerospace market.
This article is based on an official press release from Sodern.
Sodern, a prominent French manufacturer of space equipment and a subsidiary of ArianeGroup, has officially inaugurated its first United States industrial subsidiary, Sodern America. Located in Englewood, Colorado, the new facility marks a significant strategic expansion for the European aerospace giant, representing ArianeGroup’s first industrial installation on American soil.
According to the company’s announcement, the opening of Sodern America is designed to bring the manufacturer closer to its U.S. client base and navigate domestic regulatory requirements. The move positions Sodern to compete directly with established American firms in the defense and commercial space sectors by establishing a local supply chain and production capability.
The new subsidiary is situated in the Denver metropolitan area, a region widely recognized as a major hub for the U.S. aerospace industry. The facility spans approximately 14,000 square feet (1,300 square meters) and is equipped to handle manufacturing, testing, and commercial support.
In its official statement, Sodern outlined the specific operational capabilities of the Englewood site:
By establishing this physical presence, Sodern aims to address the “dynamic and demanding” nature of the U.S. market, ensuring that critical components are available with shorter supply-chains than those requiring import from Europe.
To lead the new subsidiary, Sodern has appointed Tiphaine Louradour as the CEO of Sodern America. Louradour brings over 25 years of experience in the space industry, having held significant leadership roles at major U.S. aerospace organizations.
According to biographical details released in conjunction with the announcement, Louradour’s background includes serving as CEO of Spaceflight Inc., President of International Launch Services (ILS), and President of Global Commercial Sales at United Launch Alliance (ULA). Her appointment signals Sodern’s intent to leverage deep ties within the U.S. space industrial base to secure new contracts.
A primary driver for this expansion, as noted in the company’s strategic rationale, is compliance with U.S. regulatory frameworks. Foreign entities often face barriers when bidding for U.S. government defense and civil space contracts due to strict domestic content requirements, often referred to as “Buy American” mandates. By manufacturing the Auriga™ star tracker and conducting testing in Colorado, Sodern America intends to qualify for sensitive programs that are typically restricted to U.S. entities. This local status allows the company to bypass previous regulatory hurdles and compete on equal footing with domestic manufacturers.
The entry of Sodern America into the Colorado aerospace cluster places it in direct proximity to some of its fiercest competitors. The Denver area is home to Blue Canyon Technologies (a subsidiary of RTX), which is a market leader in small satellite components and star trackers. Additionally, Ball Aerospace (now part of BAE Systems Space & Mission Systems) and Honeywell Aerospace maintain significant operations in the region.
Sodern is already a supplier for major U.S. stakeholders, including NASA, providing instruments for the InSight Mars mission and the Europa Clipper, and the OneWeb constellation. However, establishing a manufacturing foothold suggests a shift from being an exporter to becoming an embedded part of the U.S. supply chain. This move is likely to intensify competition in the optical sensors market, particularly as satellite constellations continue to scale.

Isar Aerospace Opens Acceptance Test Facility at Esrange Space Center
Isar Aerospace launches a new test site at Esrange, Sweden, to support industrial-scale production of Spectrum rocket ahead of March 2026 flight.
This article is based on an official press release from Isar Aerospace.
Isar Aerospace has officially inaugurated a new acceptance test facility at the Esrange Space Center in Kiruna, Sweden. Announced on February 4, 2026, the opening marks a significant transition for the Munich-based launch provider as it shifts focus from prototype development to the industrial-scale production of its Spectrum launch vehicle.
The new site is purpose-built to verify the flight readiness of manufactured hardware, a critical step in ensuring high-cadence Launch operations. According to the company, the facility is designed to test over 30 Aquila engines per month, alongside fully integrated rocket stages. This infrastructure expansion comes just weeks before Isar Aerospace attempts its second Test-Flights, mission “Onward and Upward,” scheduled to First-Flight from Andøya Spaceport in Norway in March 2026.
Unlike development testing, which focuses on validating design concepts, acceptance testing is the final quality control step before hardware is shipped to the launch pad. Isar Aerospace stated in their press release that the new facility is specifically engineered to remove production bottlenecks. By securing dedicated infrastructure for acceptance testing, the company aims to ensure that every engine and stage coming off the assembly line is immediately qualified for flight.
The facility operates alongside Isar’s existing vertical test stand (VTS-2) at Esrange, which has been utilized for development testing since 2019. The addition of the new site allows for parallel operations: R&D can continue on the vertical stand while the new facility handles the volume required for serial production.
“Scaling reliable access to space requires not only advanced launch vehicle design but also the right infrastructure to support rapid development and production. With our second test facility at Esrange, we are unlocking new capabilities and accelerating our progress.”
, Daniel Metzler, CEO & Co-Founder, Isar Aerospace
The new infrastructure significantly increases the company’s throughput. Isar Aerospace reports that the site is equipped to handle the acceptance testing of more than 30 Aquila engines monthly. Furthermore, the site supports integrated stage testing, allowing engineers to verify the entire rocket stage as a cohesive unit before it leaves Sweden.
The opening of this facility highlights the intensifying race among European launch Startups to provide sovereign access to space. Isar Aerospace is competing with peers such as Rocket Factory Augsburg (RFA) and Orbex to fill the gap in Europe’s launch market. By vertically integrating its testing capabilities, Isar Aerospace reduces reliance on shared facilities, potentially giving it an advantage in scheduling and launch cadence. Swedish Space Corporation (SSC), which operates Esrange, emphasized the importance of this Partnerships for the broader European ecosystem.
“This new facility strengthens Europe’s path toward scalable and reliable access to space… Together, we are building the infrastructure that will enable a new generation of launch services.”
, Mats Tyni, Director of Business Development, SSC
The distinction between “development” and “acceptance” testing is often overlooked, yet it is the primary hurdle for launch companies moving from a single successful flight to a commercial service. In our view, Isar Aerospace’s Investments in a high-volume acceptance facility signals confidence in their hardware design. It suggests the company believes the Aquila engine design is mature enough to freeze for mass production. If the upcoming March 2026 flight is successful, this infrastructure will be the key enabler that allows them to fulfill their backlog without the testing bottlenecks that have historically plagued the industry.
The facility inauguration serves as a prelude to Isar Aerospace’s next major milestone. The company confirmed that its second test flight, dubbed “Onward and Upward,” is targeted for a launch window in March 2026. This mission will utilize the Spectrum vehicle, a two-stage rocket designed to carry up to 1,000 kg to Low Earth Orbit (LEO).
The Spectrum vehicle relies on the Aquila engines tested at Esrange, which utilize Liquid Oxygen (LOX) and Propane. Following a flight termination during the first test launch in March 2025, the company has conducted extensive hot-fire tests to validate system corrections. The new acceptance facility will likely play a central role in qualifying engines for vehicles 3 through 7, which are currently planned for concurrent production.

SpaceX Crew-12 Arrives in Florida for February ISS Launch
Crew-12 astronauts from NASA, ESA, and Roscosmos arrive at Kennedy Space Center ahead of their February 11 launch to the ISS aboard SpaceX Crew Dragon.
This article is based on an official press release from NASA and additional mission data from ESA and Roscosmos.
The four-member crew of the SpaceX Crew-12 mission arrived at the Kennedy Space Center (KSC) in Florida on Friday, February 6, 2026, marking the final operational milestone before their scheduled Launch to the International Space Station (ISS). Flying in from the Johnson Space Center in Houston, the international team of astronauts landed at the Launch and Landing Facility to commence final preparations and mandatory quarantine protocols.
According to NASA, the mission is targeted to lift off on Wednesday, February 11, 2026, at 6:01 a.m. EST. The crew will ride aboard the SpaceX Crew Dragon spacecraft named Freedom, propelled by a Falcon 9 rocket from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station. This flight represents a continuation of the Commercial Crew Program’s efforts to maintain a continuous human presence in low-Earth orbit.
The arrival of Crew-12 is operationally critical for the ISS, which has recently functioned with a reduced staff due to schedule shifts and medical evaluations. The successful docking of Crew-12, targeted for approximately 10:30 a.m. EST on February 12, will restore the orbiting laboratory to its full complement of seven astronauts, stabilizing maintenance rosters and scientific output for Expeditions 74 and 75.
The Crew-12 mission brings together representatives from three major Space-Agencies: NASA, the European Space Agency (ESA), and Roscosmos. The mission duration is expected to last approximately nine months, during which the crew will conduct hundreds of scientific experiments and technology demonstrations.
In an official statement regarding the mission’s scope, NASA noted:
“Crew-12 will conduct scientific investigations and technology demonstrations to help prepare humans for future exploration missions to the Moon and Mars, as well as benefit people on Earth.”
Following the launch on February 11, the crew will execute a 28-hour rendezvous profile before docking with the ISS. Once aboard, they will overlap briefly with the departing crew before settling into a long-duration stay focused on deep space biology, material science, and Earth observation.
The manifest for Crew-12 features a blend of veteran leadership and rookie talent, including two American astronauts, one French astronaut, and one Russian cosmonaut. Leading the mission is veteran astronaut Jessica Meir. Meir previously served on Expedition 61/62 in 2019 and 2020, where she gained global recognition for participating in the first all-female spacewalk alongside Christina Koch. A dual American-Swedish citizen, Meir holds a Doctorate in Marine Biology from the Scripps Institution of Oceanography. Her scientific background includes extensive research on animal physiology in extreme environments, such as emperor penguins in Antarctica. As Mission Commander, she is responsible for all phases of flight, from launch to re-entry.
Seated alongside Meir is mission pilot Jack Hathaway, making his first trip to space. Selected as a NASA astronaut candidate in 2021, Hathaway brings extensive aviation experience as a Commander in the U.S. Navy. He is a distinguished graduate of the Empire Test Pilots’ School and has logged over 2,500 flight hours in more than 30 types of aircraft. His role on Crew-12 involves monitoring vehicle systems and performance during the dynamic phases of flight.
Representing the European Space Agency is Mission Specialist Sophie Adenot. A Lieutenant Colonel in the French Air and Space Force and a helicopter test pilot, Adenot was selected as an ESA astronaut in 2022. She becomes the second French woman to fly to space, following Claudie Haigneré’s mission in 1996. Adenot’s individual mission is designated “Epsilon.”
Commenting on the significance of her role, Adenot stated:
“With this Epsilon mission, France and Europe are contributing to a global endeavor. Space exploration connects science, economy, technology, education, and diplomacy.”
Rounding out the crew is Roscosmos cosmonaut Andrey Fedyaev. This flight marks his second journey to the ISS, having previously flown on the SpaceX Crew-6 mission from March to September 2023. Fedyaev’s inclusion in the crew is notable for making him the first Russian cosmonaut to fly twice on a SpaceX Dragon vehicle. He is tasked with monitoring launch and re-entry phases and managing cargo operations aboard the station.
Upon their arrival in Florida, the crew immediately entered the Neil A. Armstrong Operations and Checkout Building to begin the standard pre-flight quarantine. This health stabilization protocol, a legacy of the Apollo era, is designed to ensure that no viral or bacterial illnesses are transported to the closed environment of the ISS.
The composition of Crew-12 underwent a significant adjustment late in the training flow. In December 2025, Roscosmos cosmonaut Oleg Artemyev was removed from the manifest and replaced by Andrey Fedyaev. While Roscosmos officially cited a “transition to other work” as the reason for the swap, industry reports have suggested the change may have been influenced by internal Regulations. Fedyaev’s previous experience on the Crew-6 mission allowed him to step into the role with a compressed training timeline, ensuring the mission schedule remained on track.
The integration of Andrey Fedyaev into Crew-12 highlights the increasing maturity and interoperability of the Commercial Crew Program. In previous eras of spaceflight, a crew change less than three months before launch could have resulted in significant delays. However, the standardization of the SpaceX Crew Dragon platform allows veteran flyers like Fedyaev to retain currency and step into rotation with reduced lead time. Furthermore, the launch of Crew-12 is pivotal for ISS operations. The station has faced a period of flux regarding crew numbers, and the return to a seven-person staff is essential for clearing the backlog of maintenance tasks and maximizing the scientific return of the orbiting laboratory before the transition to commercial space stations begins later in the decade.
