One Year on Earth – Seen From 1 Million Miles

Jay Herman, the EPIC Lead Scientist for the Discover Mission, discusses the EPIC camera aboard the Discover satellite, which captures images of Earth from a million miles away. The camera provides a unique view of Earth, capturing images every two hours in various wavelengths. These images are used to create time-lapse sequences and study phenomena like solar eclipses and cloud cover. EPIC's data helps scientists understand Earth's climate and daily variations, contributing to efforts to protect the planet.
