NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian Space Agency astronaut Jeremy Hansen, photographed the far side of the Moon during a flyby in their Orion spacecraft on Monday.

The crew captured images of Maunder Crater, named after Strabane astronomer Annie Scott Dill Maunder, born in County Tyrone in 1868. The crater measures four kilometres deep and 54 kilometres wide. It sits on the northern fringe of Mare Orientale, the largest crater in that lunar sea.

Mare Orientale appears as a large circle with a central black patch of ancient lava, encircled by the Montes Rook mountain range.

NASA released the images as the Artemis II crew began their return to Earth on Tuesday. At that time, the spacecraft was 36,286 miles from the Moon and 236,022 miles from Strabane.

The flyby marked the first human observation of the crater in 50 years.
