NASA's SpaceX Crew-11 Launches to Advance Health Studies for Deep Space Travel

NASA’s SpaceX Crew-11 mission is set to launch a four-person crew to the International Space Station (ISS) later this summer, with a focus on addressing health challenges faced by astronauts on long-duration space missions. The mission aims to gather critical data that will support NASA’s Artemis campaign and future human expeditions to Mars.
Scheduled for liftoff in August 2025, the Crew-11 mission includes NASA astronauts Mike Fincke and Zena Cardman, Roscosmos cosmonaut Oleg Platonov, and JAXA astronaut Kimiya Yui. These crew members will participate in a series of experiments during their time aboard the ISS, with particular emphasis on health and performance studies pertinent to deep space travel.
According to Scott Wood, a neuroscientist at NASA’s Johnson Space Center and the lead investigator for this mission, the primary objectives include exploring the effects of microgravity and altered gravitational forces on human physiology. "Our research focuses on understanding how changes in gravity affect spatial awareness and piloting skills necessary for navigating lunar and Martian landscapes," Wood stated during a press briefing on July 10, 2025.
The Crew-11 mission will implement a range of simulated lunar landings to evaluate the astronauts' adaptability to different gravitational conditions. This simulation employs advanced technology that allows astronauts to fly through scenarios mimicking the lunar South Pole, where Artemis crews are expected to land.
Moreover, the mission will investigate spaceflight-associated neuro-ocular syndrome (SANS), a condition that may lead to vision problems and other neurological effects during prolonged space travel. Preliminary studies suggest that fluid redistribution in microgravity could increase intracranial pressure, contributing to SANS. To address this, researchers will examine how B vitamin supplementation may alleviate symptoms, while astronauts will also use thigh cuffs to manage bodily fluid distribution.
Crew members will participate in the Complement of Integrated Protocols for Human Exploration Research (CIPHER) study, which will measure physiological changes during spaceflight. This comprehensive study will include MRI scans, vision assessments, and other medical examinations to evaluate how long-duration missions impact the human body.
In addition to these experiments, astronauts will contribute to NASA's Spaceflight Standard Measures, a core set of metrics that collects biological samples, including blood and urine, to analyze genetic alterations induced by space travel. This data is pivotal for understanding the long-term health implications of spaceflight.
NASA's Human Research Program is dedicated to ensuring the health and safety of astronauts during missions. By conducting this array of studies, NASA seeks to mitigate risks associated with future exploration missions to the Moon, Mars, and beyond. The findings from Crew-11 may significantly inform training regimens and health protocols necessary for sustaining human life in deep space environments.
As NASA continues its ambitious plans for human exploration of the solar system, the insights gained from Crew-11 will provide foundational knowledge to enhance astronaut readiness and resilience in the face of the unique challenges posed by deep space travel.
