Overall fracture rates were not higher, but hip fractures were more common after flights longer than 90 days, and happened at younger ages than expected in people who have not flown. The authors call for bone checks beyond standard bone density scans; NASA has begun ordering detailed CT scans of bone before and after flight.

Both new studies and analyses of existing data are welcome. Responses are due by 1:00 PM Central (2:00 PM ET) on November 20, 2026.

Their planned studies include how spaceflight affects blood flow and clotting (with MRI scans, neck-vein ultrasound, blood pressure checks and blood draws), and the continuing B-Complex study of whether a daily B-vitamin supplement can reduce or prevent spaceflight-associated neuro-ocular syndrome, the eye changes seen on long missions.

Gene-activity changes were larger in younger crewmembers and on longer missions, including signs of stressed mitochondria (the cell’s energy units). There was no clear difference by sex. The authors say it is not yet known whether the stronger response helps or harms.

Until then, operators must get written informed consent and tell occupants the government has not certified the vehicle as safe. An industry rulemaking committee delivered its recommendations to the FAA in 2025. Status as of October 15, 2026; FAA page last updated April 14, 2026.
