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 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.

6 NASA Experiments on Materials, Benefitting Space and Earth

6 NASA Experiments on Materials, Benefitting Space and Earth

Did you know that NASA conducts ground-breaking research in space on materials like metals, foams, and crystals? This research could lead to next-generation technology that both enables deep-space exploration and benefits humanity.  

Here are six studies scientists have conducted on the International Space Station that could have profound implications for future space travel and also improve products widely used on Earth:  

  • 01

    Advancing construction and repairing techniques with liquid metals 

    Researchers are looking at the effects of microgravity on the liquid metals formed during brazing, a technology used to bond materials at temperatures above 450 degrees Celsius.  The Brazing of Aluminum alloys In Space (BRAINS) experiment aboard the International Space Station studies how alloys join with a range of other materials, such as ceramics or other metals. 
     
    In space, brazing could be used to construct vehicles, habitats, and other systems needed for space missions, and repair them if damaged. Advanced brazing technologies discovered in space may also be used in the construction and repair of structures on Earth.

  • 02

    Improving materials used for high-powered lasers 

    Another study on the space station is looking at the growth of semiconductor crystals based on Zinc selenide (ZnSe) in microgravity.  ZnSe is an important semiconductor used on Earth for optical devices and infrared lasers.  
     
    Researchers are investigating the impact of microgravity on the growth of these crystals and comparing the results to those grown on Earth.  A better understanding of the impact of microgravity on crystal growth could open the door to expanded commercial use of space.  

  • 03

    Researching ways to make stronger metal 

    Metal alloys, which are created by combining two or more metallic elements, are used in everything from hardware to kitchen appliances, automobiles, and even the space station itself. Alloys are created by cooling a liquid metal until it hardens into a solid.  
     
    Researchers on the space station are investigating how metal alloys melt and take shape in a controlled microgravity environment. While brazing aims to repair or bond two separate materials, this experiment looks at casting or molding things from liquid metals. In metal castings, the solid grows by forming millions of snowflake-like crystals called dendrites. The shape of the dendrites affects the strength of the metal alloys.  
     
    Findings are expected to significantly impact our ability to produce metals with greater strength, for both space and on Earth applications.  

  • 04

    Exploring stability and mechanics of foams and bubbly liquids

    Studying how foams and bubbly liquids evolve in microgravity over time is another important NASA investigation. These experiments will provide guidance for how to control the flow and separation of bubbly liquids. This knowledge is crucial for developing a water recovery and recycling device for future space exploration to Mars.  
     
    On Earth, foams are found in everything from food and cosmetics to paper and petroleum. A better understanding of their stability and mechanics is important for creating sustainable, more efficient processes and improved materials.  

  • 05

    Improving performance and lowering cost of “superglass” 

    Scientists are conducting experiments on supercooled metal oxides (space soil and rock) to better understand how molten materials can be processed in microgravity. Manufacturing new products in space is critical to long-term efforts to develop habitats in space and on other planets. It will require the use of available resources in space, including soil and rocks.  
     
    Data from the research also has far-reaching implications on Earth. It could help improve the performance and lower the cost of materials that are used in the production of cell phone displays, lasers, and glass for automobiles.  

  • 06

    Advancing 3D printing and manufacturing through “soft matter” research

    Space exploration to Mars and beyond will require astronauts to have the ability to build new equipment and materials in space. To make that a reality, space station researchers conducted a number of experiments looking at the behavior of colloids, or “soft matter,” in a microgravity environment.  
     
    This research could have a variety of applications on Earth, including the development of chemical energy, improvements to communications technologies, and enhancements to photonic materials used to control and manipulate light.
