Earth observing satellites play a fundamental role in understanding our planet and how humankind is affecting Earth’s delicate balance. Using cutting-edge technology, Earth Explorer missions reveal new insights into how the oceans, cryosphere, atmosphere, land and Earth’s interior work as a system. While science continues to reap the benefits of these missions, we are now in a new era where Earth observation is benefiting society at large.
