With a second Trump Administration at the helm in 2025, NASA marked significant progress toward the Artemis II test flight early next year, which is the first crewed mission around the Moon in more than 50 years, as well as built upon its momentum toward a human return to the lunar surface in preparation to send the first astronauts — Americans — to Mars.
As part of the agency’s Golden Age of innovation and exploration, NASA and its partners landed two robotic science missions on the Moon; garnered more signatories for the Artemis Accords with 59 nations now agreeing to safe, transparent, and responsible lunar exploration; as well as advanced a variety of medical and technological experiments for long-duration space missions like hand-held X-ray equipment and navigation capabilities.
NASA also led a variety of science discoveries, including launching a joint satellite mission with India to regularly monitor Earth’s land and ice-covered surfaces, as well as identifying and tracking the third interstellar object in our solar system; achieved 25 continuous years of human presence aboard the International Space Station; and, for the first time, flew a test flight of the agency’s X-59 supersonic plane that will help revolutionize air travel.
Sean Duffy, named by President Trump, is serving as the acting administrator while NASA awaits confirmation of Jared Isaacman to lead the agency. Isaacman’s nomination hearing took place in early December, and his nomination was passed out of committee with bipartisan support. The full Senate will consider Isaacman’s nomination soon. President Trump also nominated Matt Anderson to serve as deputy administrator, and Greg Autry to serve as chief financial officer, both of whom are awaiting confirmation hearings. NASA named Amit Kshatriya to associate administrator, the agency’s highest-ranking civil servant position.
Key accomplishments by NASA in 2025 include:
Astronauts exploring Moon, Mars is on horizon
Under Artemis, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to build upon our foundation for the first crewed mission to Mars. The Artemis II test flight is the first flight with crew under NASA’s Artemis campaign and is slated to launch in early 2026. The mission will help confirm systems and hardware for future lunar missions, including Artemis III’s astronaut lunar landing.
NASA also introduced 10 new astronaut candidates in September, selected from more than 8,000 applicants. The class is undertaking nearly two years of training for future missions to low Earth orbit, the Moon, and Mars.
Progress to send the first crews around the Moon and on the lunar surface under Artemis includes:
- NASA completed stacking of its Space Launch System rocket and Orion spacecraft for Artemis II. Teams integrated elements manufactured across the country at NASA’s Kennedy Space Center in Florida, including the rocket’s boosters and core stage, as well as Orion’s stage adapter and launch abort system, to name a few.
- Ahead of America’s 250th birthday next year, the SLS rocket’s twin-pair of solid rocket boosters showcases the America 250 emblem.
- The Artemis II crew participated in more than 30 mission simulations alongside teams on the ground, ensuring the crew and launch, flight, and recovery teams are prepared for any situation that may arise during the test flight. Soon, crew will don their survival suits and get strapped into Orion during a countdown demonstration test, serving as a dress rehearsal for launch day.
- The agency worked with the Department of War to conduct a week-long underway recovery test in preparation to safely collect the Artemis II astronauts after they splashdown following their mission.
- To support later missions, teams conducted a booster firing test for future rocket generations, verified new RS-25 engines, test-fired a new hybrid rocket motor to help engineering teams better understand the physics of rocket exhaust and lunar landers, as well using various mockups to test landing capabilities in various lighting conditions. Teams also conducted human-in-the-loop testing in Japan with JAXA (Japan Aerospace Exploration Agency) with a rover mockup from their agency.
- NASA also continued work with Axiom Space, to develop and test the company’s spacesuit, including completing a test run at the Neutral Buoyancy Laboratory at NASA Johnson ahead of using the suit for Artemis training. The spacesuit will be worn by Artemis astronauts during the Artemis III mission to the lunar South Pole.
- On the Moon, future crew will use a lunar terrain vehicle, or LTV, to travel away from their landing zone. NASA previously awarded three companies feasibility studies for developing LTV, followed by a request for proposals earlier this year. The agency is expected to make an award soon to develop, deliver, and demonstrate LTV on the lunar surface later this decade. The agency also selected two science instruments that will be included on the LTV to study the Moon’s surface composition and scout for potential resources.
- For operations around the Moon, NASA and its partners continued to develop Gateway to support missions between lunar orbit and the Moon’s surface. Construction and production of the first two elements, a power and propulsion system and habitation element, each progressed, as did development and testing of potential science and technology demonstrations operated from Gateway. International partners also continued work that may contribute technology to support those elements, as well as additional habitation capabilities and an airlock.
- This past year, NASA’s Lunar Surface Innovation Consortium team collaborated with over 3,900 members from academia, industry, and government on key lunar surface capabilities. Members from across the U.S. and 71 countries participated in two biannual meetings, three lunar surface workshops, and monthly topic meetings, resulting in 10 studies, four reports, and nine conference presentations.
Building on previous missions and planning for the future, NASA will conduct more science and technology demonstrations on and around the Moon than ever before. Work toward effort included:
- Selected a suite of science studies for the Artemis II mission, including studies that focus on astronauts’ health.
- Launched two CLPS (Commercial Lunar Payload Services) flights with NASA as a key customer, including Firefly’s Blue Ghost Mission One, which landed on the Moon March 2, and Intuitive Machines’ Nova C lunar lander, which touched down on March 6.
- Experiments and tech demos aboard these flights included an electrodynamic dust shield, lunar navigation system, high-performance computing, collection of more than 9,000 first-of-a-kind images of the lunar lander’s engine plumes, and more.
- For future CLPS flights, NASA awarded Blue Origin a task order with an option to deliver the agency’s VIPER (Volatiles Investigating Polar Exploration Rover) to the lunar South Pole in late 2027, as well as awarded Firefly another flight, slated for 2030.
- Teams studied regolith (lunar dirt and rocks) in a simulated lunar gravity environment and tested how solid materials catch fire in space.
- The agency’s 55-pound CubeSat in lunar orbit, CAPSTONE, exceeded 1,000 days in space, serving as a testbed for autonomous navigation and in-space communications.
- Published findings from this Artemis I experiment highlighting why green algae may be a very good deep space travel companion.
