During an hour-long presentation, Mr Bezos introduced Blue Origin’s prototype lunar lander, a machine that could be ready, he said, to meet America’s ambitions to return to the Moon by 2024.

Mr Bezos has no interest in Mars, or indeed any other planet in the solar system, all of which (except Earth) are pretty inhospitable places. Instead, he thinks humans should build their new space-going homes from scratch.
