In December 1972, Apollo 17 astronauts captured one of the clearest views of a fully illuminated Earth, an image that came to be known as the Blue Marble. The photograph—the first image of a fully illuminated side of Earth—became one of the most famous images of all time, and it has rarely been replicated, due to the difficulties of staging such a shot.
Located in an orbit one million miles away, between the Earth and the sun, NASA’s Deep Space Climate Observatory (DSCOVR for short) is in the perfect position to capture such photos. The satellite returned its first Blue Marble image, made of three different images taken with different filters, earlier this month.
The satellite launched in February and will be gathering data on solar wind, ozone levels, cloud height, and more. It will return an image like the one above every day. Say cheese!
