Cape Canaveral (US), 23 Feb

A private lander touched down on the moon on Thursday but managed just a weak signal back, as flight controllers scrambled to gain better contact with the first US spacecraft to reach the lunar surface in more than 50 years.

Despite the spotty communication, Intuitive Machines, the company that built and managed the craft, confirmed that it had landed. There was no immediate word from the company on the condition — or even the exact location — of the lander. The company ended its live webcast soon after confirming a touchdown.

Mission director Tim Crain said the team was evaluating how to refine the lone signal from the lander, named Odysseus. “But we can confirm, without a doubt, that our equipment is on the surface of the moon," he said.

Added Intuitive Machines CEO Steve Altemus: “I know this was a nail-biter, but we are on the surface and we are transmitting. Welcome to the moon.”

The landing put the US back on the surface for the first time since NASA's famed Apollo moonwalkers.

Intuitive Machines also became the first private business to pull off a lunar landing, a feat achieved by only five countries. Another company gave it a shot last month, but never made it to the moon, and the lander crashed back to Earth.

Odysseus descended from a moon-skimming orbit and guided itself toward the surface, searching for a relatively flat spot among all the cliffs and craters near the south pole.

Tension mounted in the company's Houston command centre following the designated touchdown time, as controllers awaited a signal from the spacecraft some 250,000 miles (400,000 kilometres) away. After close to 15 minutes, the company announced it had received a weak signal from the lander.

Launched last week, the six-footed carbon fibre and titanium lander — towering 14 feet (4.3 metres) — carried six experiments for NASA. The space agency gave the company USD 118 million to build and fly the lander, part of its effort to commercialize lunar deliveries ahead of the planned return of astronauts in a few years.

Intuitive Machines' entry is the latest in a series of landing attempts by countries and private outfits looking to explore the moon and, if possible, capitalise on it. Japan scored a lunar landing last month, joining earlier triumphs by Russia, US, China and India.

The US bowed out of the lunar landscape in 1972 after NASA's Apollo programme put 12 astronauts on the surface. A Pittsburgh company, Astrobotic Technology, gave it a shot last month, but was derailed by a fuel leak that resulted in the lander plunging back through Earth's atmosphere and burning up.
