Odysseus, the first U.S.-built spacecraft to land on the moon since 1972, encountered a setback just before touchdown, ultimately resting horizontally on its side on the lunar surface.

Steve Altemus, CEO of the Houston-based company Intuitive Machines responsible for building the lander, explained that the team initially believed the unmanned six-footed lander had landed upright.

However, data transmitted from Odysseus revealed its horizontal position.

Altemus suggested that as the lander descended vertically and laterally, it likely “caught a foot in the surface and tipped over,” USA Today reported.

Evidence supporting the notion that the lander is not fully horizontal is derived from the power generated by its solar array, according to Altemus.
