Applications for future space habitats, cancer research, and biomanufacturing are among investigations headed to the International Space Station on second all-private astronaut mission to the orbiting laboratory
Axiom Space, a leader in human spaceflight and architect of the world’s first commercial space station, announced today further details on the groundbreaking research planned for the upcoming Axiom Mission 2 (Ax-2) mission to the International Space Station (ISS) – including initial studies focused on developing future therapeutic applications, studying immune dysfunction in tumor organoid models that can help to predict and prevent cancer, understanding how commercial spaceflight crew members adapt to microgravity, and exploring how weather modification works in low-gravity conditions.
Axiom Space’s crew of four astronauts will conduct more than 20 different experiments while aboard the space station. Data collected in flight will impact understanding of human physiology on Earth and on orbit, as well as establish the utility of novel technologies that could be used for future human spaceflight pursuits and improving life on Earth.
Unique to this mission, there is a strong focus on projects developing in-space biomanufacturing applications. Four experiments flying on Ax-2 are part of larger partnerships between Axiom Space and academic and industrial partners to perform proof-of-concept studies for in-space biomanufacturing, which has the potential to address current roadblocks in regenerative medicine, drug development, and technology advancement.
"It is exciting to see the wide range of important research that will be conducted on this mission and to be taking the first steps in developing future in-space manufacturing applications for some of our biomedical products," said Christian Maender, executive vice president of in-space solutions at Axiom Space. "We are pleased to have the opportunity with our private astronaut missions to advance this important work as we build a future commercial space economy.
Axiom Space’s Chief Scientist Dr. Lucie Low echoed Maender’s excitement for the science on the mission, “We’re delighted to support these scientific and research and manufacturing projects on the Ax-2 mission, as well as provide opportunities to conduct research in microgravity for partner countries and nations with limited access.” said Low. “The projects flying on this mission will advance the use of low-Earth orbit as a manufacturing platform for technologies that could advance human health on Earth, add to our understanding of health in space, and demonstrate how to best operate safely and effectively on orbit.”
The Ax-2 crew members are Commander Peggy Whitson and Pilot John Shoffner, both from the United States, and Mission Specialists Ali Alqarni and Rayyanah Barnawi representing the Kingdom of Saudi Arabia.
A SpaceX Falcon 9 rocket will launch the Ax-2 crew aboard a Dragon spacecraft to the International Space Station no earlier than spring 2023 from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
