A private U.S. lunar lander is expected to stop working Tuesday, its mission cut short after landing sideways near the south pole of the moon.

Intuitive Machines, the Houston company that built and flew the spacecraft, said Monday it will continue to collect data until sunlight no longer shines on the solar panels. Based on the position of Earth and the moon, officials expect that to happen Tuesday morning. That's two to three days short of the week or so that NASA and other customers had been counting on.

The lander, named Odysseus, is the first U.S. spacecraft to land on the moon in more than 50 years, carrying experiments for NASA, the main sponsor. But it came in too fast last Thursday and the foot of one of its six legs caught on the surface, causing it to tumble over, according to company officials.

Based on photos from NASA's Lunar Reconnaissance Orbiter flying overhead, Odysseus landed within a mile or so (1.5 kilometers) of its intended target near the Malapert A crater, just about 185 miles from the moon's south pole.

The LRO photos from 56 miles up are the only ones showing the lander on the surface, but as little more than a spot in the grainy images. A camera-ejecting experiment by Embry-Riddle Aeronautical University, to capture images of the lander as they both descended, was called off shortly before touchdown because of a last-minute navigation issue.

According to NASA, the lander ended up in a small, degraded crater with a 12-degree slope. That's the closest a spacecraft has ever come to the south pole, an area of interest because of suspected frozen water in the permanently shadowed craters there.
