NASA astronauts will study blood flow and clotting risks during Crew-13 mission
NASA plans biomedical investigations for its SpaceX Crew-13 crew aboard the International Space Station to assess health effects of spaceflight.

New European collaboration on blood studies
A new project called Venous Haemostasis joins NASA and the European Space Agency to examine how microgravity affects circulation. Researchers will coordinate blood collections to reduce the frequency of draws needed from astronauts. This effort builds on previous studies regarding blood flow in space environments.
Testing manual piloting and re-entry forces
The mission includes tests of crew members manual piloting skills alongside evaluations of vision and brain changes. Scientists are also gathering data on forces astronauts experience during their return to Earth. These measurements will help refine future re-entry hardware and procedures.
Understanding risks of slow blood flow
Jason Lytle notes that weightlessness can disrupt normal blood flow in the veins of astronauts. Irregular or slow circulation increases the risk of forming blood clots, which is a serious health condition. The Venous Haemostasis study aims to understand why these disruptions occur.
