The SpaceX Dragon spacecraft carrying the Axiom Mission 3 crew is pictured approaching the International Space Station on Jan. 20, 2024.Credit: NASA NASA, Axiom Space, and SpaceX are targeting 2:31 a.m. EDT, Wednesday, June 25, for launch of the fourth private astronaut mission to the International Space Station, Axiom Mission 4.
The mission will lift off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The crew will travel to the orbiting laboratory on a new SpaceX Dragon spacecraft after launching on the company’s Falcon 9 rocket. The targeted docking time is approximately 7 a.m. Thursday, June 26.
This launch opportunity comes after NASA and Roscosmos officials discussed the status of the recent repair work in the transfer tunnel at the aft (back) most segment of the orbital laboratory’s Zvezda service module. Based on the evaluations, NASA and Roscosmos agreed to further lower the pressure in the transfer tunnel to 100 millimeters of mercury, and teams will continue to evaluate going forward. Safety remains a top priority for NASA and Roscosmos.
“NASA and Roscosmos have a long history of cooperation and collaboration on the International Space Station. This professional working relationship has allowed the agencies to arrive at a shared technical approach and now Axiom Mission 4 launch and docking will proceed,” said acting NASA Administrator Janet Petro. “We look forward to the launch with Axiom Space and SpaceX for this commercial international mission.”
For this mission, NASA is responsible for integrated operations, which begins during the spacecraft’s approach to the space station, continues during the crew’s stay aboard the orbiting laboratory conducting science, education, and commercial activities, and concludes once the spacecraft departs the station.
Live coverage of launch and arrival activities will stream on NASA+. Learn how to watch NASA content through a variety of platforms, including social media.
Peggy Whitson, former NASA astronaut and director of human spaceflight at Axiom Space, will command the commercial mission, while ISRO (Indian Space Research Organisation) astronaut Shubhanshu Shukla will serve as pilot. The two mission specialists are ESA (European Space Agency) project astronaut Sławosz Uznański-Wiśniewski of Poland, and HUNOR (Hungarian to Orbit) astronaut Tibor Kapu of Hungary.
Once docked, the private astronauts plan to spend about two weeks aboard the orbiting laboratory, conducting a mission comprised of science, outreach, and commercial activities.
As part of a collaboration between NASA and ISRO, Axiom Mission 4 delivers on a commitment highlighted by President Donald Trump and Indian Prime Minister Narendra Modi to send the first ISRO astronaut to the station. The space agencies are participating in five joint science investigations and two in-orbit STEM (science, technology, engineering, and mathematics) demonstrations. NASA and ISRO have a long-standing relationship built on a shared vision to advance scientific knowledge and expand space collaboration.
The private mission also carries the first astronauts from Poland and Hungary to stay aboard the International Space Station.

The International Space Station is a springboard for developing a low Earth economy. NASA’s goal is to achieve a strong economy off the Earth where the agency can purchase services as one of many customers to meet its science and research objectives in microgravity. NASA’s commercial strategy for low Earth orbit provides the government with reliable and safe services at a lower cost, enabling the agency to focus on Artemis missions to the Moon in preparation for Mars while also continuing to use low Earth orbit as a training and proving ground for those deep space missions.

Ozone high in the stratosphere protects us from the Sun’s ultraviolet light. But ozone near the ground is a pollutant that harms people and plants. The San Joaquin Valley has some of the most polluted air in the country, and NASA scientists with the new Ozone Where We Live (OWWL) project are working to measure ozone and other pollutants there. They need your help!
Do you live or work in Bakersfield, CA? Sign up to host an ozone sensor! It’s like a big lunch box that you place in your yard, but it’s not packed with tuna and crackers. It’s filled with sensors that measure temperature and humidity and sniff out dangerous gases like methane, carbon monoxide, carbon dioxide, and of course, ozone.
Can you fly a plane? Going to the San Joaquin Valley? Sign up to take an ozone sensor on your next flight! You can help measure ozone levels in layers of the atmosphere that are hard for satellites to investigate. Scientists will combine the data you take with data from NASA’s TEMPO satellite to improve air quality models and measurements within the region. Find out more here or email: Emma.l.yates@nasa.gov

Mission Accomplished! Artemis ROADS III National Challenge Competitors Celebrate their Achievements
The NASA Science Activation program’s Northwest Earth and Space Sciences Pathways (NESSP) team has successfully concluded the 2024–2025 Artemis ROADS III National Challenge, an educational competition that brought real NASA mission objectives to student teams (and reached more than 1,500 learners) across the country. From December 2024 through May 2025, over 300 teams of upper elementary, middle, and high school students from 22 states participated, applying STEM (Science, Technology, Engineering, and Mathematics) skills in exciting and creative ways.
Participants tackled eight Mission Objectives inspired by NASA’s Artemis missions, which aim to return humans to the Moon. Students explored challenges such as:
Designing a water purification system for the Moon inspired by local water cycles Developing a Moon-based agricultural plan based on experimental results Programming a rover to autonomously navigate lunar tunnels Engineering and refining a human-rated water bottle rocket capable of safely returning a “chip-stronaut” to Earth Envisioning their future careers through creative projects like graphic novels or video interviews Exploring NASA’s Artemis program through a new Artemis-themed Lotería game In-person hub events were hosted by Northern Arizona University, Central Washington University, and Montana State University, where teams from Washington, Montana, and Idaho gathered to present their work, collaborate with peers, and experience life on a college campus. Students also had the chance to connect virtually with NASA scientists and engineers through NESSP’s NASA Expert Talks series.
“Artemis ROADS III is NESSP’s eighth ROADS challenge, and I have to say, I think it’s the best one yet. It’s always inspiring to see so many students across the country engage in a truly meaningful STEM experience. I heard from several students and educators that participating in the challenge completely changed their perspective on science and engineering. I believe that’s because this program is designed to let students experience the joy of discovery and invention—driven by both teamwork and personal creativity—that real scientists and engineers love about their work. We also show students the broad range of STEM expertise NASA relies on to plan and carry out a mission like Artemis. Most importantly, it gives them a chance to feel like they are part of the NASA mission, which can be truly transformative.”
– Dr. Darci Snowden, Director, NESSP

NASA tested RS-25 engine No. 20001 on June 20, at the Fred Haise Test Stand at NASA’s Stennis Space Center at Bay St. Louis, Mississippi. Test teams fired the engine for almost eight-and-a-half minutes (500 seconds), the same amount of time RS-25 engines fire during a launch of an SLS (Space Launch System) rocket on Artemis missions to the Moon. NASA NASA tested RS-25 engine No. 20001 on June 20, at the Fred Haise Test Stand at NASA’s Stennis Space Center at Bay St. Louis, Mississippi. Test teams fired the engine for almost eight-and-a-half minutes (500 seconds), the same amount of time RS-25 engines fire during a launch of an SLS (Space Launch System) rocket on Artemis missions to the Moon. The Artemis campaign will 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.
Four RS-25 engines, built by contractor L3Harris Technologies (formerly Aerojet Rocketdyne), help power each SLS launch, producing up to 2 million pounds of combined thrust. During the test, operators also fired engine No. 20001 up to the 111% power level, the same amount of thrust needed to launch an SLS rocket, carrying the Orion spacecraft, to orbit. The full-duration “hot fire” was the first test since NASA completed certification testing for new production RS-25 engines in 2024.
All RS-25 engines are tested and proven flightworthy at NASA Stennis. The test was conducted by a team of operators from NASA, L3Harris, and Syncom Space Services, prime contractor for site facilities and operations.
