It is being created to send between 3.6 and 6.5 metric tons to the lunar surface and can transport payloads ranging from multiple rovers to a human-rated ascent stage.
It is supported by four legs, with an upper deck where equipment can be fixed. "It's time to go back to the moon, this time to stay", Bezos said at a press event in Washington, DC on Thursday. But that first flight is still a few years off.
Blue Moon, as it's called, has actually been in development for three years, according to Blue Origin. It will be capable of carrying scientific instruments and also rovers for humans. The lander also offers kilowatts of power for its payloads via fuel cells, enabling both nighttime operations and long-duration missions.
The water derived from that ice can be broken down to produce hydrogen, which could then fuel up the spacecraft for further missions across the solar system. It plans to launch the powerful space vehicle from Cape Canaveral.
In March, the Trump administration announced that it meant to return USA astronauts to the Moon by the end of 2024. Astronauts have not walked on the moon since 1972.
With NASA, the European Space Agency and others aiming to go to the moon, government business could provide a boon to companies hoping to set up shop there, but how well they will do is still speculative. Bezos also owns the Washington Post, which Trump has frequently targeted in his broadsides about "fake news".
"My generation's job is to build the infrastructure", said Bezos. "We're going to leave it, and it's going to make this planet better", Mr Bezos told GeekWire.
And Blue origin aims to do the same, with a massive heavy-lift rocket called New Glenn (named for astronaut and later senator John Glenn, the first American to orbit the Earth).
Bezos confirmed his commitment to fly the first people in New Shepard this year, and New Glenn in 2021. A much smaller, reusable rocket, New Shepard, is created to take six paying tourists to the edge of space for a few minutes of weightlessness.
