Utilizing a sleeper ship, on which the spacecraft crew is put into deep sleep while they travel, is one way to theoretically send people to Mars. NASA has backed a study by aerospace engineering firm, SpaceWorks Enterprises, Inc., that is exploring how humans can be put into a prolonged deep sleep using therapeutic hypothermia. Therapeutic hypothermia is standard of care at hospitals for some trauma patients, including patients at St. Louis Children’s Hospital. Photo is provided by SpaceWorks Enterprises, Inc.
