: ESA project astronaut Marcus Wandt wears a cap with sensors to record his brain activity during a session of the Orbital Architecture experiment in ESA’s Cupola module. The experiment investigates how people’s physical and psychological well-being can be affected by living on the International Space Station. The Swedish astronaut will carry out tasks on a computer while wearing the cap. Researchers will monitor a whole range of parameters to see how Marcus copes with the new environment, including his heart rate, brain activity, sleep quality, diet and exercise routine.
