By studying the space environment around the Earth we can better understand how it effects our lives, and our planet. Spaceflight osteopenia causes astronauts to lose, on average, more than 1% of bone mass per month in space, making them good subjects to study and learn more about osteoporosis and how to help minimise its effects. Altimetry from space provides information on sea level, and the size and health of glaciers and ice-caps in detail that is otherwise near-impossible. An ever-increasing understanding of our impact on our planet, and our responsibilities to take better care of it.
