NASA | Getting the Big Picture

Remote sensing allows us to measure Earth's features without physical contact, using NASA's aircraft and satellites. It employs passive and active methods to monitor environmental changes, such as soil moisture, snowpack, and ice sheets. Remote sensing overcomes challenges like rugged terrain and vast oceans, providing comprehensive data for better climate predictions and understanding of the water cycle. By observing Earth from above, we gain insights into surface, atmospheric, and underground changes globally.
