Stand back a metre and pan slowly - even light helps
On the evening of 2 April 2026 the crew of Artemis II photographed the terminator, the line between night and day, from a stable high Earth orbit. Their spacecraft, Orion, was minutes from leaving. At 19:49 its main engine fired for five minutes and 50 seconds. The burn carried four people out of Earth orbit for the first time since Apollo 17 in 1972.
The camera's own clock puts the exposure at 19:45:18, under four minutes before ignition. The shutter ran at 1/1000 of a second, a daylight setting for a sunlit subject, so no star was bright enough to register. Earth is a crescent here, lit from the right, and the disc touches no edge; roughly two thirds of the picture is unlit sky. NASA released it on 22 April, for Earth Day.
