Space travel can be so delightful but at the same time invisibly dangerous.For instance,astronauts lose bone mass.That's why exercise is considered so vital that National
Aeronautics and Space Administration (NASA) puts it right on the workday schedule.The focus on fitness is as much about science and the future as it is about keeping any individual astronaut healthy.NASA is worried about two things: recovery time once astronauts return home,and,more importantly,how to maintain strength and fitness for the two and a half years or more that it would take to make a roundtrip to Mars.
