Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:

Actigraphy is one of nine Spaceflight Standard Measures conducted on International Space Station (ISS) crewmembers. Spaceflight Standard Measures are a collection or set of core measurements, representative of many of the human spaceflight risks, collected on astronauts before, during and after International Space Station (ISS) missions. The purpose of this project is to populate a repository with data that enables high-level monitoring of countermeasure effectiveness and meaningful interpretation of health and performance outcomes, as well as support future, hypothesis-driven research that enables planetary missions, as well as, optimized minimal set of measures captured from all ISS crewmembers until the end of the ISS program. These measures will serve the population as a data repository and be available to other studies under data sharing agreements, as well as, undergo analysis for trends in the astronaut population.
