Exploration
at Goddard
At Goddard, exploration is a system that builds outward, grounded in understanding Earth, extending through the space environment, and enabling safe and sustained missions to the Moon, Mars, and beyond.
The Sciences and Exploration Directorate (SED) brings together complementary scientific disciplines that work in concert to make exploration possible. Each contributes in a distinct way, while collectively forming a unified exploration enterprise.

Total Solar Eclipse from Greenland
On August 12, the Moon's shadow reached out to touch our fair planet. Beginning in the Arctic Ocean, it swept along a narrow track that led the dark lunar umbra across parts of Greenland, Iceland, the Atlantic, Portugal, and northern Spain. And for a moment, denizens of Earth who found themselves with clear skies under the shadow of the Moon could witness a total solar eclipse. After dodging the weather by sea and making a landing along Rype Fjord on the Greenland east coast (at 71.07055N, 27.71252W), this hard-won snapshot was captured at 17:33:26 UTC. That's near the initial reach of clearing skies along the path of totality, so the image is likely one of the first unobstructed views of the totally eclipsed Sun. Through a break in the clouds, the stunning photo also records one of this eclipse's transient diamond rings and the magnificent solar corona emerging near the moment totality began.
