NASA astronauts Suni Williams and Butch Wilmore began a spacewalk at approximately 7:43 a.m. EST to remove a radio frequency group antenna assembly from the station’s truss, collect samples of surface material for analysis from the Destiny laboratory and the Quest airlock to see whether microorganisms may exist on the exterior of the orbital complex, and prepare a spare elbow joint for the Canadarm2 robotic arm.

Crew Ready for Thursday Spacewalk, Keeps Up Space Agriculture Research

Crew Ready for Thursday Spacewalk, Keeps Up Space Agriculture Research

The Expedition 72 crew members have completed preparations for a science and maintenance spacewalk scheduled for Thursday. Space agriculture, Earth observations, and lab maintenance rounded out the day for the International Space Station residents.

Commander Suni Williams and Flight Engineer Butch Wilmore, two NASA astronauts who are scheduled to begin a spacewalk at 8 a.m. EST on Thursday, have completed their procedure reviews and spacesuit checks. They also joined NASA Flight Engineers Nick Hague and Don Pettit and practiced on a computer the Canadarm2 robotic arm maneuvers necessary to remove radio communications hardware, the first of two main spacewalking tasks. The second main task will see the two spacewalkers swab sites outside the orbital outpost to collect samples of potential microbes for analysis.

Hague began his day in the Kibo laboratory module making space and readying the Astrobee robotic free flyers for operations testing their ability to downlink video and imagery to mission controllers in real time. Pettit was back on space gardening duty processing samples and installing research hardware for an investigation exploring how microgravity and ultraviolet radiation affect plant growth. Results may enable future crews to grow crops on spacecraft for sustainment during long-term space missions.

The three cosmonauts working in the Roscosmos segment of the orbiting lab focused on imaging Earth landmarks and installing new electronics hardware. Flight Engineer Aleksandr Gorbunov once again set up a camera with a spectrometer attach       ed and photographed areas along the Mediterranean Sea in a variety of wavelengths, including Libya and Greece. Flight Engineers Alexey Ovchinin and Ivan Vagner continued installing new command and telemetry gear in the Zvezda service module that can communicate with Soyuz and Progress spacecraft, ground stations, and orbiting satellites.

NASA will hold a media teleconference at 2 p.m. EST on Tuesday, Feb. 4, to share information about the agency’s upcoming PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission, which is targeted to launch no earlier than Thursday, Feb. 27.

The agency’s PUNCH mission is a constellation of four small satellites. When they arrive in low Earth orbit, the satellites will make global, 3D observations of the Sun’s outer atmosphere, the corona, and help NASA learn how the mass and energy there become solar wind. By imaging the Sun’s corona and the solar wind together, scientists hope to better understand the entire inner heliosphere – Sun, solar wind, and Earth – as a single connected system.

Audio of the teleconference will stream live on the agency’s website at:

https://www.nasa.gov/live

Participants include:

  • Madhulika Guhathakurta, NASA program scientist, NASA Headquarters
  • Nicholeen Viall, PUNCH mission scientist, NASA’s Goddard Space Flight Center
  • Craig DeForest, PUNCH principal investigator, Southwest Research Institute

To participate in the media teleconference, media must RSVP no later than 12 p.m. on Feb. 4 to: Abbey Interrante at: abbey.a.interrante@nasa.gov. NASA’s media accreditation policy is available online. 

The PUNCH mission will share a ride to space with NASA’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) space telescope on a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California. 

The Southwest Research Institute in Boulder, Colorado, leads the PUNCH mission. The mission is managed by the Explorers Program Office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for NASA’s Science Mission Directorate in Washington.

NASA, Partners to Welcome Fourth Axiom Space Mission to Space Station

NASA and its international partners have approved the crew for Axiom Space’s fourth private astronaut mission to the International Space Station, launching from the agency’s Kennedy Space Center in Florida no earlier than spring 2025.

Peggy Whitson, former NASA astronaut and director of human spaceflight at Axiom Space, will command the commercial mission, while ISRO (Indian Space Research Organization) astronaut Shubhanshu Shukla will serve as pilot. The two mission specialists are ESA (European Space Agency) project astronaut Sławosz Uznański-Wiśniewski of Poland and Tibor Kapu of Hungary.

“I am excited to see continued interest and dedication for the private astronaut missions aboard the International Space Station,” said Dana Weigel, manager of NASA’s International Space Station Program at the agency’s Johnson Space Center in Houston. “As NASA looks toward the future of low Earth orbit, private astronaut missions help pave the way and expand access to the unique microgravity environment.”

The Axiom Mission 4, or Ax-4, crew will launch aboard a SpaceX Dragon spacecraft and travel to the space station. Once docked, the private astronauts plan to spend up to 14 days aboard the orbiting laboratory, conducting a mission comprised of science, outreach, and commercial activities. The mission will send the first ISRO astronaut to the station as part of a joint effort between NASA and the Indian space agency. The private mission also carries the first astronauts from Poland and Hungary to stay aboard the space station.

“Working with the talented and diverse Ax-4 crew has been a deeply rewarding experience,” said Whitson. “Witnessing their selfless dedication and commitment to expanding horizons and creating opportunities for their nations in space exploration is truly remarkable. Each crew member brings unique strengths and perspectives, making our mission not just a scientific endeavor, but a testament to human ingenuity and teamwork. The importance of our mission is about pushing the limits of what we can achieve together and inspiring future generations to dream bigger and reach farther.”

The first private astronaut mission to the station, Axiom Mission 1, lifted off in April 2022 for a 17-day mission aboard the orbiting laboratory. The second private astronaut mission to the station, Axiom Mission 2, also was commanded by Whitson and launched in May 2023 with four private astronauts who spent eight days in orbit. The most recent private astronaut mission, Axiom Mission 3, launched in January 2024; the crew spent 18 days docked to the space station.

The International Space Station is a convergence of science, technology, and human innovation that enables research not possible on Earth. For more than 24 years, NASA has supported a continuous human presence aboard the orbiting laboratory, through which astronauts have learned to live and work in space for extended periods of time.

The space station is a springboard for developing a low Earth economy. NASA’s goal is to achieve a strong economy in low Earth orbit 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 will provide 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.
