NASA’s Crew‑12 wraps up ISS research as astronauts prepare for return
The four‑person crew completed experiments on crystal growth, quantum atoms, bone scaffolds and antibiotic resistance before heading home.
By Felo News Desk · Published
NASA’s SpaceX Crew‑12 mission is concluding, with the four‑person crew slated to depart the International Space Station in early October, NASA announced on Oct. 2.
What happened
During their six‑month stay, astronauts Jessica Meir and Jack Hathaway (NASA), ESA astronaut Sophie Adenot and Roscosmos cosmonaut Andrey Fedyaev carried out a series of microgravity experiments. Highlights included crystal growth studies for cancer‑targeting drugs, upgrades to the Cold Atom Lab for quantum research, a bone‑scaffold test aimed at osteoporosis treatment, investigations of colloidal solids for material science, and testing for antibiotic‑resistant bacteria.
What the reports add
The NASA release details each experiment’s purpose: the Pharmaceutical In‑space Laboratory (ADSEP‑PIL‑15) seeks to improve drug stability; the Cold Atom Lab upgrade increases atom production for quantum‑technology research; the “Green Bone” project uses a wooden scaffold to study bone regeneration in weightlessness; and the colloidal‑solid study examines particle interactions that could inform 3‑D printing and plant growth. The agency also notes that the crew’s work supports future deep‑space missions.
What was said
NASA’s description does not quote the astronauts directly, but attributes each activity to the respective crew member – Meir operating the Cold Atom Lab, Hathaway handling crystal‑growth hardware, Adenot managing the bone‑scaffold container, and Hathaway also overseeing antibiotic‑resistance tests.
How it came about
The Crew‑12 flight follows a series of recent ISS missions that have emphasized microgravity research to benefit life on Earth and prepare for lunar and Martian exploration. Earlier this year, NASA highlighted the retirement of SpaceX’s Crew Dragon and the shift toward Boeing’s Starliner, underscoring the agency’s reliance on ISS science to justify continued crewed launches.
