![]() ![]() Before a scheduled call, students learn about the station, radio waves, and other topics, and prepare a list of questions based on the topics they have researched. ISS Ham Radio provides students, teachers, and others the opportunity to communicate with astronauts using amateur radio units. ![]() The experience helps inspire the next generation of scientists, engineers, and explorers. Students write software to control the space station’s Astrobee free-flying robots for Zero Robotics.Crew members exercised on the Advanced Resistive Exercise Device (ARED) during the week for the investigation. Results could help determine whether other exercise regimens are adequate to maintain physical health on future missions. Zero T2 examines the effects on bone, muscle, and aerobic health and performance when crew members do not exercise on a treadmill during flight. Treadmills currently used to reinforce the motor pattern of walking in astronauts are too bulky and heavy for future long-term missions. Missions to the Moon and Mars need to include exercise devices that provide a variety of aerobic and resistance options to maintain astronaut health and physical fitness and also meet launch weight and mass limits. Crew members wore the headband for several sessions during the week. The easy-to-use tool also could help improve sleep for people on Earth. This device collects a variety of data including sleep duration, stages, and number of awakenings and heart rate. Sleep conditions for astronauts can be stressful and monitoring their sleep quality is difficult with the devices currently available. Dreams, an investigation from ESA (European Space Agency), demonstrates a wearable headband to monitor astronaut sleep quality during spaceflight. Insufficient sleep and sleep disorders can impair performance and increase the risk of medical problems such as cardiovascular disease. ![]()
