Astronaut, Scott Kelly (who grew up in West Orange) has currently been in space since March 27.
Together with his previous missions, he has been in space for more total time (390 days) than any other American.
The purpose of this trip is to help scientists analyze space travel’s long term effects (weightlessness, isolation, radiation and stress among others) upon the human body.
Scott’s twin brother Mark is on the ground participating in the study by comparing the way the two age in their different environments.
