Space Station Research Informs New FDA-Approved Cancer Therapy (News Release)

NASA opens the International Space Station for scientists and researchers, inviting them to use the benefits of microgravity for commercial and public research, technology demonstrations, and more. Today, a portion of the crew’s time aboard station is devoted to private industry, including medical research that addresses complex health challenges on Earth and prepares astronauts for future deep space missions.

In collaboration with scientists at Merck, protein crystal growth research on the space station yielded early insights regarding the structure and size of particles best suited for the development of a new formulation of the company’s cancer medicine pembrolizumab for subcutaneous injection. This new route of delivery was approved by the U.S. Food and Drug Administration last September and offers a time-saving alternative to intravenous infusion for certain patients. These research efforts aboard the space station were supported by the ISS National Laboratory.

Originally, the treatment was delivered during an in-office visit via infusion therapy into the patient’s veins, a process that could take up to two hours. Initial delivery improvements reduced infusion times to less than 30 minutes every three weeks. The newly-approved subcutaneous injectable form takes about one minute every three weeks, promising to improve quality of life for patients by reducing cost and significantly reducing treatment time for patients and healthcare providers.

Since 2014, Merck has flown crystal growth experiments to the space station to better understand how crystals form, including the monoclonal antibody used in this cancer treatment. Monoclonal antibodies are lab-made proteins that help the body fight diseases. This research focused on producing crystalline suspensions that dissolve easily in liquid, making it possible to deliver the medication by injection.

In microgravity, the absence of gravity’s physical forces allows scientists to grow larger, more uniform, and higher-quality crystals than those grown in ground-based labs, advancing medication development and structural modeling.

Research aboard the space station has provided valuable insights into how gravity influences crystallization, helping to improve drug formulations. The work of NASA and its partners aboard the space station improves lives on Earth, grows a commercial economy in low-Earth orbit, and prepares for human exploration of the Moon and Mars.

NASA Welcomes Mauritius as 70th Artemis Accords Signatory (News Release)

The Republic of Mauritius has officially joined the global coalition committed to responsible space exploration, becoming the newest signatory and seventh African country to join the Artemis Accords. NASA’s Deputy Administrator Matt Anderson contributed video remarks for a signing ceremony on Friday, in the island nation’s city of Ébène.

“We are honored to welcome Mauritius to the Artemis Accords community and look forward to working together in the years ahead,” said Anderson. “Together, we are creating the foundation for future exploration while ensuring that space remains peaceful, accessible and beneficial for all. America will return to the Moon and ignite the Golden Age of exploration and discovery. That work requires capable partners and a shared commitment to responsible exploration.”

Mauritius’ Permanent Secretary at the Ministry of Tertiary Education, Science and Research Navindsing Jugmohunsing signed the Artemis Accords on behalf of the country. U.S. Deputy Assistant Secretary of State for African Affairs Sarah Troutman and U.S. Chargé d’Affaires to Mauritius Craig Halbmaier were present to witness the signing.

“The accession of Mauritius to the Artemis Accords marks a defining chapter in our New Space journey,” said Jugmohunsing. “As a Small Island Developing State in the Indian Ocean, we are committed to ensuring that space serves humanity by protecting our oceans and coastlines and amplifying the voices of nations like ours. Mauritius stands ready to help shape the future of space governance while unlocking new opportunities for innovation and partnership.”

NASA first engaged with Mauritius through its early global mapping efforts, owing to the nation’s strategic location. Between 1965 and 1980, NASA used several satellite missions to collect global measurements of Earth’s size and shape. As part of that work, NASA sent teams to Mauritius and other international tracking stations that supported satellite photography for geodetic analysis.

The teams' observations strengthened the navigation technologies used from Apollo to Artemis and helped lay the foundation for the partnership reaffirmed today by the Artemis Accords.

In 2020, NASA and the Department of State joined with seven other founding nations to establish the Artemis Accords, responding to the growing interest in lunar activities by both governments and private companies. They introduced the first set of practical principles aimed at enhancing the safety and coordination between like-minded nations as they explore the Moon, Mars and beyond, committing nations to:

-- explore peaceably and transparently
-- render aid to those in need
-- enable access to scientific data
-- ensure that activities do not interfere with those of others
-- preserve historically significant sites and artifacts by developing best practices

More countries are expected to sign the Artemis Accords in the months and years ahead, as NASA continues its work to establish a safe, peaceful and prosperous future in space.

NASA Welcomes Serbia as Newest Artemis Accords Signatory (News Release)

The Republic of Serbia signed the Artemis Accords on Thursday during a ceremony hosted by NASA at the agency’s headquarters in Washington, becoming the 69th nation to join a large community of like-minded nations committed to the peaceful, transparent and responsible exploration of space.

“Serbia’s connection to NASA reaches back to the Apollo program, when the work of Serbian engineers helped make some of humanity’s greatest achievements in space possible,” said NASA Deputy Administrator Matt Anderson. “Among them was Milojko ‘Mike’ Vučelić, who was awarded the Presidential Medal of Freedom for the critical role he played in bringing the Apollo 13 crew safely home. Their story stands as a reminder that the greatest achievements in space are made possible by talented people working together.”

The broader team of Serbian American engineers played key roles during the Apollo era across systems engineering, propulsion, power systems, spacecraft docking, electronics reliability, and mission coordination. Their expertise supported critical functions ranging from lunar landing analysis to safe spacecraft docking.

Serbia’s Minister of Foreign Affairs Marko Đurić signed the Artemis Accords on behalf of the country.

“The great beyond has always inspired humanity to achieve its greatest feats — from the Roman ‘per aspera ad astra’ to Norman Vincent Peale’s belief that if we aim for the Moon, we will at least land among the stars,” said Đurić. “Those words feel especially fitting today. We come from a nation of great minds like Nikola Tesla and Milutin Milanković, but also from the legacy of David Vujic, one of the pioneers of the Apollo missions and a member of the ‘Serbian Seven,’ a group of engineers and technicians whose contributions to NASA helped make the Moon landing possible. In that spirit, we owe it to both our brave ancestors and our children to keep pushing toward new frontiers — to explore, to inspire one another, and to dare even greater things.”

By signing the Artemis Accords, nations open the door to opportunities for future lunar exploration with NASA, such as providing science and technology payloads for the U.S.-led Moon Base and CubeSats for upcoming Artemis missions, advancing humanity’s return to the Moon, and shaping the Golden Age of space exploration and innovation.

Ambassador of the Republic of Serbia to the United States Dragan Šutanovac; State Secretary for Serbia’s Ministry of Science, Technological Development and Innovation Marija Gnjatović; and U.S. Department of State Assistant Secretary for Oceans and International Environmental and Scientific Affairs Wesley Brooks all participated in Serbia’s signing ceremony.

It was on this day back in 2011 that Atlantis took off from Launch Complex 39A at NASA's Kennedy Space Center in Florida...beginning mission STS-135 to the International Space Station that lasted 12 days, 18 hours, 28 minutes and 50 seconds, and successfully concluded the 30-year space shuttle program. 15 years later, this anniversary is marked by humans finally venturing to the Moon once more on last April's Artemis 2 mission...and NASA gearing up for Artemis 3, an Earth-orbiting test flight that will pave the way for astronauts returning to the lunar surface on Artemis 4.

The time period between 2011 and 2020 (when SpaceX's Demo-2 flight resumed crewed launches from U.S. soil for the first time since STS-135) was marked by delays and uncertainty in America's human spaceflight program. But as of 2026, things are absolutely picking up with mankind moving ever so closer to maintaining a sustainable presence at the Moon, and finally, sending humanity on a much-awaited voyage to Mars. The future of space exploration has never been more promising than this!

“Botswana like many countries, we have interest in space exploration, found it important to become a signatory to the Artemis Accords to promote the safe, transparent and sustainable civil space exploration, and to advance international cooperation, and a shared framework for responsible activities in the space,” said Tshere.

This new chapter builds on Botswana’s long history of collaboration with the United States in space-based Earth observation. In the early 1970s, Botswana participated in the satellite program later known as Landsat, joining dozens of other nations in pioneering satellite-based environmental observation. Botswana marked another milestone with the launch of its first Earth observation satellite, Botswana Satellite 1, in March 2025, aboard a SpaceX Falcon 9.

In 2020, the United States, led by NASA and the State Department, joined with seven other founding nations to establish the Artemis Accords, responding to the growing interest in lunar activities by both governments and private companies. The Artemis Accords introduced the first set of practical principles aimed at enhancing the safety and coordination between like-minded nations as they explore the Moon, Mars and beyond.

Signing the Artemis Accords means committing to explore peaceably and transparently, to render aid to those in need, to enable access to scientific data that all of humanity can learn from, to ensure that activities do not interfere with those of others, and to preserve historically significant sites and artifacts by developing best practices for space exploration for the benefit of all.

More countries are expected to sign the Artemis Accords in the months and years ahead, as NASA continues its work to establish a safe, peaceful and prosperous future in space.

Artemis IV Liquid Oxygen Tank Moves to Next Phase of Production (Photo Release)

Teams at NASA’s Michoud Assembly Facility in New Orleans use a heavy-lift mobile transport apparatus to move a 51-foot-tall liquid oxygen tank out of the vertical assembly building and into the main rocket factory on June 11. The liquid oxygen tank will form part of the SLS (Space Launch System) rocket for NASA’s Artemis IV mission to the Moon. Next, technicians with Boeing, SLS core stage prime contractor, and NASA will perform dimensional inspections and install internal baffles on the propellant tank before the next phase of production.

The propellant tank will hold more than 196,000 gallons of super-cooled liquid oxygen at launch and is one of five major elements that make up the 212-foot-tall SLS rocket stage. The core stage, along with its four RS-25 engines at its base, produces more than two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts and supplies beyond Earth’s orbit and to the lunar surface for Artemis.

NASA Marches Toward Artemis III Mission in 2027, Names Crew Members (News Release)

Taking another step towards one of the most complex human spaceflight missions in recent history, NASA on Tuesday provided new Artemis III details and announced the four prime crew members and a backup for the test flight. The mission will undertake a series of challenging tests in Earth orbit in 2027, essential for Artemis IV, the first planned crewed mission to the lunar South Pole in 2028.

During Artemis III, the agency’s SLS (Space Launch System) rocket will launch the Orion spacecraft and its crew from NASA’s Kennedy Space Center in Florida to low-Earth orbit. After Orion systems checkouts, the spacecraft will, for the first time, demonstrate rendezvous and docking capabilities with test versions from one, or both, American commercial Human Landing Systems in development by Blue Origin and SpaceX. This highly-choreographed mission includes a dramatic multi-launch campaign of the world’s most powerful rockets, testing integrated hardware between Orion and the landers, including system interfaces, software, propulsion and communications.

Crew assignments are as follows:

-- NASA astronaut Randy Bresnik, commander
-- ESA (European Space Agency) astronaut Luca Parmitano, pilot
-- NASA astronaut Andre Douglas, mission specialist
-- NASA astronaut Frank Rubio, mission specialist

As part of Tuesday’s event, NASA astronaut Bob Hines was named as a backup crew member. The crew will begin training immediately on Orion spacecraft systems, as well as assist in the development and operations of the test versions of Blue Origin and SpaceX landers.

“Today we take another bold step in humanity’s return to the Moon, building on the extraordinary foundation laid by the Artemis II astronauts,” said NASA Administrator Jared Isaacman. “Their achievements reignited global excitement for exploration, and now they pass the torch to the Artemis III team, Randy, Luca, Frank and Andre. Artemis III will demonstrate the power of American innovation and international partnership as we test complex rendezvous and docking operations and advance the technologies that will one day carry us deeper into the Solar System.

“This mission will require the most awe-inspiring coordination of heavy-lift rocket launches in history, drawing on the talent and capability of teams across government and the spaceflight community. The Artemis III astronauts, alongside ESA and our international partners, and the tens of thousands of the best and brightest across the agency and industry, are ushering in a new Golden Age of exploration carrying forward the hopes and dreams of the next generation just as the Apollo astronauts did for so many of us.”

This is also the first time that an ESA astronaut has been assigned to an Artemis mission.

“Artemis III will push the boundaries of spacecraft operations in orbit. Luca’s assignment as pilot reflects the depth of European expertise in human spaceflight and draws on his extensive operational experience in high-pressure situations,” said Josef Aschbacher, ESA’s director general. “At the same time, ESA’s European Service Module will once again provide the critical capabilities that power Orion, demonstrating Europe’s enduring role at the very heart of the Artemis program. The news out of Houston today is a powerful recognition of ESA’s role in enabling humanity’s return to the Moon – and a key advancement in our partnership with NASA. Europeans can take pride in being part of this exciting journey.”

Mission progress

NASA and its partners are making progress preparing for the test flight.

Engineers will connect the Orion crew module and service module this summer and integrate the spacecraft’s docking system, which will fly for the first time. Heat shield testing continues with individual blocks having undergone ultra-sonic inspections and installation onto the heat shield structure.

Rocket processing is also well underway. Technicians for SLS are integrating the engine section to the rest of the core stage ahead of installing the four RS-25 engines this summer. With all solid rocket booster segments now at NASA Kennedy and Mobile Launcher refurbishments on track, rocket stacking is also scheduled to begin this summer.

NASA continues design and fabrication of a spacer that will replace the upper stage on Artemis III.

Blue Origin is developing a crewed lunar version of the company’s Blue Moon lander, while SpaceX is developing a crewed lunar lander version of the company’s Starship, with both companies building test articles for Artemis III. NASA is supporting both lander providers hands-on throughout design, development, testing and evaluation, including sharing agency expertise and capabilities gained from previous missions.

In addition to status updates from NASA and both commercial partners, the agency discussed details during the event about the planned operations for Artemis III, which will support an increased mission cadence, ramp up production, and drive supply chain improvements for the Artemis program.

The Artemis III mission builds on the successful Artemis II flight completed in April and will help the agency prepare to send the first astronauts, Americans, to Mars.

Artemis III includes launching the world’s most powerful rockets in short order. Blue Origin’s lander pathfinder, which is able to stay in orbit for multiple weeks, will launch first and await the crew. NASA will send the astronauts aboard Orion by SLS to orbit Earth, before rendezvousing in space with the company’s lander test article and spending about two days docked together for tests and technology demonstrations, including entering the lander.

After completing docked operations with Blue Origin, Orion will detach and await Starship. SpaceX’s Starship pathfinder will launch and meet up with Orion to spend about a day connected for checkouts and testing. After that, Orion and its crew will undock and return home, safely splashing down in the Pacific Ocean where a team from the U.S. Navy and NASA will recover the astronauts.

In total, the crew is expected to remain in space for about two weeks, with exact mission length to be determined in real-time based on launch, rendezvous and docked operations.
