A Japanese company hoping to make history by carrying out the first private Moon landing says its mission is likely to have failed.
Ednews reports citing Washington Post that communication was lost with the Hakuto-R lunar lander moments before it was due to touch down.
Engineers are investigating what happened.
The Tokyo-based iSpace had hoped the lander would release an exploratory rover, as well as a tennis-ball-sized robot developed by a toymaker.
The craft was launched by a SpaceX rocket in December, and has taken five months to reach its destination.
The United States, Russia and China are the only countries to have managed to put a robot on the lunar surface, all through government-sponsored programmes.
