Japanese start-up ispace conceded on Wednesday that its attempt to become the first company to land on the Moon had failed.
The unmanned Hakuto-R Mission 1 lander was scheduled to touch down on the Moon's surface overnight, but the firm could not establish contact.
The company said its engineers were working to establish why the landing had failed, and it is currently developing two further attempts to land on the lunar surface.
The mission had begun with the lander's launch last December aboard a SpaceX Falcon 9 rocket, and it was carrying a lunar rover from the UAE.
