Berliner Tageblatt - Commercial US spaceship descending toward lunar surface

If all goes well, Intuitive Machines will guide its hexagon-shaped lander Odysseus to a gentle touchdown near the lunar south pole at 2324 GMT, having slowed down from 4,000 miles per hour (6,500 kph).

Flight controllers are expected to confirm landing around 15 seconds after the milestone is achieved, with the event live streamed on the company's website.

As Odysseus approaches the surface it will shoot out an external "EagleCam" that captures images of the lander in the final seconds of its descent.

A previous moonshot by another US company last month ended in failure, raising the stakes to demonstrate that private industry has what it takes to repeat a feat last achieved by NASA during its manned Apollo 17 mission in 1972.

The current mission "will be one of the first forays into the south pole to actually look at the environmental conditions to a place we're going to be sending our astronauts in the future," said senior NASA official Joel Kearns.

"What type of dust or dirt is there, how hot or cold does it get, what's the radiation environment? These are all things you'd really like to know before you send the first human explorers."

Odysseus launched on February 15 on a SpaceX Falcon 9 rocket and boasts a new type of supercooled liquid oxygen, liquid methane propulsion system that allowed it to race through space in quick time.

Its destination, Malapert A, is an impact crater 300 kilometers (180 miles) from the lunar south pole.

NASA hopes to eventually build a long-term presence and harvest ice there for both drinking water and rocket fuel under Artemis, its flagship Moon-to-Mars program.

Instruments carried on Odysseus include cameras to investigate how the lunar surface changes as a result of the engine plume from a spaceship, and a device to analyze clouds of charged dust particles that hang over the surface at twilight as a result of solar radiation.

It also carries a landing system that fires laser pulses, measuring the time taken for the signal to return and its change in frequency to precisely judge the spacecraft's velocity and distance from the surface, to avoid a catastrophic impact.

The hardware will run for approximately seven days until lunar night occurs, which will render Odysseus inoperable.

The rest of the cargo was paid for by Intuitive Machines' private clients, and includes 125 stainless steel mini Moons by the artist Jeff Koons.

There's also an archive created by a nonprofit whose goal is to leave backups of human knowledge across the solar system.

NASA paid Intuitive Machines $118 million to ship its hardware under a new initiative called Commercial Lunar Payload Services (CLPS), which it created to delegate cargo services to the private sector to achieve savings and stimulate a wider lunar economy.

The first, by Pittsburgh-based Astrobotic, launched in January, but its Peregrine spacecraft sprung a fuel leak and it was eventually brought back to burn up in Earth's atmosphere.

Spaceships landing on the Moon have to navigate treacherous boulders and craters and, absent an atmosphere to support parachutes, must rely on thrusters to control their descent. Roughly half of the more than 50 attempts have failed.

Until now, only the space agencies of the Soviet Union, United States, China, India and Japan have accomplished the feat, making for an exclusive club.
