Answer:
1. Research at the Hawaii Space Exploration Analog and Simulation (HI-SEAS) project, funded in part by NASA, is a continuation of a long history of attempts to understand what will happen to people who travel through outer space for long periods of time. It’s more than a technical problem. Besides multistage rockets to propel a spacecraft out of Earth’s atmosphere, years of planning and precise calculations and massive amounts of fuel, traveling the tens of millions of miles to Mars will take a tremendous amount of time.
2. With current technology, the journey takes more than eight months each way. Which means that astronauts will get bored. In fact, a number of scientists say that — of all things — boredom is one of the biggest threats to a manned Mars mission, despite the thrill inherent in visiting another planet. And so, attention is being paid to the effects of boredom at HI-SEAS, and on the International Space Station.
3. Because of the causes of chronic boredom, scientists say, research facilities in Antarctica might actually provide a better simulation of the stress of a journey to Mars.
