Elon Musk, the billionaire founder of SpaceX, has claimed it would be easier for his company to land on the moon than try to convince NASA that the company is up to the task.
In an interview with Time magazine, Musk acknowledged he was going to "sound pretty crazy", before stating: "I think we could land on the moon in less than two years."
However, Musk, who is SpaceX's chief executive, is optimistic about his company's ability to reach the moon by 2021, and potentially by 2022 with crew.
He told Time: "Certainly with an uncrewed vehicle I believe we could land on the moon in two years. So then maybe within a year or two of that we could be sending crew."
He explained that "we" did not necessarily mean the United States, but could just refer to SpaceX.
"If it were to take longer to convince NASA and the authorities that we can do it versus just going it, the we might just do it," Musk added.

"It may literally be easier to just land Starship on the moon than try to convince NASA that we can."
Starship is the company's new spacecraft, which will only complete sub-orbital flights, or "hops", racing high into the atmosphere before landing back on Earth.
