Night and (Earth) Day
This image, released in celebration of Earth Day, shows the terminator – the line between night and day – on Earth. The Artemis II astronauts captured this view on April 2, 2026, during their journey to the Moon.
NASA science improves life on Earth every day. We provide insights on our home planet that can only be gathered from space, which can then be used for disaster response, farming, and more. In addition, our observations of Earth and the technologies we develop provide the foundation needed to explore and sustain human life on the Moon, Mars, and beyond.
