What does it take to survive a year in orbit?
In short: Beyond the view of Earth, life aboard the International Space Station is a complex balancing act. From managing microgravity risks to maintaining nutrition, every detail of daily existence is a calculated experiment designed to prepare humanity for the even greater challenges of deep space travel.
During Expedition 44, NASA Flight Engineer Scott Kelly and Roscosmos crewmate Mikhail Kornienko embarked on a year-long mission to study the effects of long-duration spaceflight. By the fourth month of their stay, the duo was actively gathering biomedical data essential for planning future human missions to Mars. This research is part of a broader effort to understand how the human body responds to the unique environment of the International Space Station (ISS). The mission, documented in interviews on July 14, serves as a critical window into the biological shifts occurring during extended stays in orbit.
Life in microgravity requires constant management of physical and logistical hurdles. NASA engineers and scientists work to predict and solve problems ranging from optimal nutrition to the physiological risks posed by weightlessness. Maintaining health involves a specialized team of medical physicians, psychologists, nutritionists, and exercise scientists. These experts ensure that crew members can thrive despite the extreme conditions of an orbiting laboratory. This scientific oversight is a continuous effort, as people have inhabited the station for more than two decades.
Daily routines on the ISS involve ingenious workarounds for basic human needs. Simple tasks like washing hair, using the bathroom, or even drinking coffee require specialized equipment, such as space cups or drink bags. Despite being physically removed from Earth, astronauts remain connected to their home societies; they can even participate in elections using absentee ballots or early voting coordinated with their local county clerks. Every aspect of their existence, from hygiene to group dynamics, serves as a blueprint for the next frontier of exploration. Beyond the station, NASA also utilizes the Human Exploration Research Analog, or HERA, to simulate the psychological pressures of deep space missions.
