Backdropped by Earth's horizon and the blackness of space, the International Space Station is featured in this image by an STS-131 crew member on space shuttle Discovery. With up to a 20-minute one-way lag in communications, they’ll have to wait 40 minutes to get a response to each message they send to Earth. They won’t be able to have a real-time conversation with anyone but their crewmates. Those luxuries won’t be available to astronauts bound for Mars, who will be disconnected from home and the life they knew in a way unprecedented in the history of spaceflight. Resupply missions can bring love notes, fresh fruit, and Thanksgiving dinners from Earth. They can have media events and press conferences and throw virtual first pitches at baseball games. They can talk and video-chat with loved ones, mission controllers, and doctors in real-time. Many of those current countermeasures involve keeping astronauts feeling connected to home. A HI-SEAS crewmember participates in a year-long simulated Mars mission in Mauna Loa, Hawaii. “We are actually really good at countermeasures and support for the International Space Station,” says Kelley Slack, an industrial-organizational psychologist who is part of NASA’s Behavioral Health and Performance group that helps select and train astronauts.
