NASA’s SpaceX Crew-12 mission is concluding with the crew scheduled to return to Earth in early October. The team, consisting of NASA astronauts Jessica Meir and Jack Hathaway, European Space Agency astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev, will depart the International Space Station after supporting a wide range of scientific investigations.
The orbiting laboratory serves as a unique platform for observing both Earth and the cosmos. Research conducted in microgravity allows scientists to study phenomena that are difficult or impossible to replicate on the ground. These experiments range from cellular behavior to material science, providing new pathways for discovery that benefit life on Earth and prepare humans for deep space exploration.
Advancing Cancer Treatments and Quantum Technologies
Jack Hathaway has been involved in hardware testing for crystal growth experiments. Microgravity reveals new details about crystal structures, which helps researchers improve the quality and stability of pharmaceuticals. This work includes crystallizing cancer-targeting treatments to better understand their properties and advance therapies on Earth. The Pharmaceutical In-space Laboratory, specifically the ADSEP-PIL-15 project, is a key component of this effort.
Jessica Meir has worked extensively with the Cold Atom Lab, using cables to deliver light that cools, traps, and studies atoms. In the microgravity environment, ultracold atoms can be observed for longer periods, giving scientists a clearer window into quantum mechanics. A recent upgrade to the facility has increased the number of atoms produced, providing more data to advance quantum technologies. These advancements could improve the development of solar cells and the components that power modern computers and cell phones.
Medical Breakthroughs in Bone and Tissue Engineering
Sophie Adenot has conducted research on bone health using a small container housing a bone scaffold made from wood. This scaffold is designed to mimic the structure of real bones and support the growth of bone cells. Since microgravity can accelerate bone loss, the experiment offers a unique opportunity to test how well the scaffold promotes bone regeneration. Insights from this study could protect future space explorers and provide new treatment options for patients with osteoporosis, a disease affecting more than 200 million people globally.
Meir has also worked on an investigation into engineered cartilage tissue. Studying how this tissue develops in microgravity may help scientists produce medical implants that more closely resemble natural cartilage. For millions of people with cartilage injuries, space-grown tissue could offer treatment options that do not require transplanting cartilage from another part of the body. This project, known as Biomimetic Tissue Engineering in Microgravity for Cartilage using Aggregate Rejuvenation, Tension, and Self Assembly, or BEM-CARTS, is a significant step forward in regenerative medicine.
Preparing for Long-Duration Spaceflight
The crew has also focused on technologies essential for long-duration missions. Adenot installed the Metal 3D Printer aboard the orbital complex. Several small metal parts have already been 3D printed in microgravity and returned to Earth for quality evaluation. Producing metal parts on demand in space could give future crews the ability to make or replace what they need far from Earth, reducing reliance on spare parts and resupply missions.
Adenot also worked to produce intravenous fluid on demand in microgravity. Commercial IV fluids expire after about 16 months, and carrying them on long-duration missions adds weight and takes up valuable space. This system could provide a critical medical resource when resupply is limited and improve access in remote areas or during emergencies on Earth. The Intravenous Fluid Generation Mini project, or IVGEN Mini, addresses these logistical challenges.
Hathaway and Meir have also conducted stem cell investigations. Microgravity can help produce larger numbers of clinical-grade stem cells that retain their ability to transform into other cells. Cells used in this experiment, part of the Hematopoietic Stem Cell Expansion in Space Pathfinder Investigation, could help rebuild blood and immune systems after chemotherapy. This work advances care for leukemia and other blood diseases on Earth.
The crew’s return follows the delivery of fresh produce and new science via NASA’s Northrop Grumman Commercial Resupply Services 24 mission. The Cygnus XL spacecraft also delivered research projects, including an instrument that could improve space-weather modeling and a project that could help protect gut-microbiome stability on future exploration missions.
