CAPE CANAVERAL, Fla. — 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 1.5 kilometers of its intended target near the Malapert A crater, just 300 kilometers from the moon’s south pole.

The LRO photos from 90 kilometers 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.

NASA, which plans to land astronauts in this region in the next few years, paid Intuitive Machines $118 million to deliver six experiments to the surface. Other customers also had items on board.

Instead of landing upright, the 4.3-meter Odysseus came down on its side, hampering communication with Earth. Some antennas were covered up by the toppled lander, and the ones still exposed ended up near the ground, resulting in spotty communications. The solar panels also ended up much closer to the surface than anticipated, less than ideal in the hilly terrain. Even under the best of circumstances, Odysseus only had a week to operate on the surface before the long lunar night set in.

Since the 1960s, only the U.S., Russia, China, India and Japan have successfully pulled off moon landings, and only the U.S. with crews. Japan’s lander ended up on the wrong side, too, just last month.

Despite its slanted landing, Intuitive Machines became the first private business to join the elite group. Another U.S. company, Astrobotic Technology, gave it a try last month, but didn’t make it to the moon because of a fuel leak.

Intuitive Machines almost failed, too. Ground teams did not turn on the switch for the lander’s navigating lasers before the Feb. 15 liftoff from Florida. The oversight was not discovered until Odysseus was circling the moon, forcing flight controllers to rely on a NASA laser-navigating device that was on board merely as an experiment.

As it turned out, NASA’s test lasers guided Odysseus to a close to bull’s-eye landing, resulting in the first moon landing by a U.S. spacecraft since the Apollo program.

Twelve Apollo astronauts walked on the moon from 1969 through 1972. While NASA went on to put an occasional satellite around the moon, the U.S. did not launch another moon-landing mission until last month. Astrobotic’s failed flight was the first under NASA’s program to promote commercial deliveries to the moon.

Both Intuitive Machines and Astrobotic hold NASA contracts for more moon landings.

Tokyo — Japan’s moon lander has produced another surprise by waking up after the two-week lunar night, the country’s space agency said Monday.

The unmanned Smart Lander for Investigating Moon (SLIM) touched down last month at a wonky angle that left its solar panels facing the wrong way.

As the sun’s angle shifted, it came back to life for two days and carried out scientific observations of a crater with a high-spec camera, the Japan Aerospace Exploration Agency (JAXA) said.

It went to sleep again as darkness returned and, since it was “not designed for the harsh lunar nights,” JAXA had been uncertain whether it would reawaken.

“Yesterday we sent a command, to which SLIM responded,” JAXA said on X, formerly Twitter, on Monday.

“SLIM succeeded in surviving a night on the Moon’s surface while maintaining its communication function!”

It said that communications were “terminated after a short time, as it was still lunar midday and the temperature of the communication equipment was very high.”

But it added: “Preparations are being made to resume operations when instrument temperatures have sufficiently cooled.”

SLIM, dubbed the “Moon Sniper” for its precision landing technology, touched down within its target landing zone on Jan. 20.

The feat was a win for Japan’s space program after a string of recent failures, making the nation only the fifth to achieve a “soft landing” on the moon, after the United States, the Soviet Union, China and India.

But during its descent, the craft suffered engine problems and ended up on its side, meaning the solar panels were facing west instead of up.

The latest news comes after JAXA toasted a successful blast-off for its new flagship H3 rocket on Feb. 17, making it third time lucky after years of delays and two previous failed attempts.

Countries including Russia, South Korea and the United Arab Emirates are also trying to reach the moon.

The first American spaceship to the moon since the Apollo era, the uncrewed Odysseus lander built by a private company and funded by NASA, landed near the lunar south pole on Thursday.

But its maker said the US spacecraft is probably lying sideways following its dramatic landing, even as ground controllers work to download data and surface photos from it.

Private Japanese firm ispace also attempted to land on the moon last year but the probe suffered a “hard landing” and contact was lost.

SEOUL, South Korea — South Korea’s government gave striking young doctors four days to report back to work, saying Monday that they won’t be punished if they return by the deadline but will face indictments and suspensions of medical licenses if they don’t.

About 9,000 medical interns and residents have stayed off the job since early last week to protest a government plan to increase medical school admissions by about 65%. The walkouts have severely hurt the operations of their hospitals, with numerous cancellations of surgeries and other treatments.

Government officials say adding more doctors is necessary to deal with South Korea’s rapidly aging population. The country’s current doctor-to-patient ratio is among the lowest in the developed world. 

The strikers say universities can’t handle so many new students and argue the plan would not resolve a chronic shortage of doctors in some key but low-paying areas like pediatrics and emergency departments.

Vice Health Minister Park Min-soo said during a televised briefing Monday that the government won’t seek any disciplinary action against striking doctors if they return to work by Thursday.

“We want them to return to work by the end of this month, Feb. 29. If they return to the hospitals they had left by then, we won’t hold them responsible” for any damages caused by their walkouts, Park said.

But he said those who don’t meet the deadline will be punished with a minimum three-month suspension of their medical licenses and face further legal steps such as investigations and possible indictments.

Under South Korea’s medical law, the government can issue back-to-work orders to doctors and other medical personnel when it sees grave risks to public health. Refusing to abide by such an order can bring up to three years in prison or $22,480 in fines, along with revocation of medical licenses.

There are about 13,000 medical interns and residents in South Korea, most of them working and training at 100 hospitals. They typically assist senior doctors during surgeries and deal with inpatients. They represent about 30% to 40% of total doctors at some major hospitals.

The Korea Medical Association, which represents about 140,000 doctors in South Korea, has said it supports the striking doctors, but hasn’t determined whether to join the trainee doctors’ walkouts. Senior doctors have held a series of rallies voicing opposition to the government’s plan.

Earlier this month, the government announced universities would admit 2,000 more medical students starting next year, from the current 3,058. The government says it aims to add up to 10,000 doctors by 2035. 

A public survey said about 80% of South Koreans back the government plan. Critics suspect doctors, one of the best-paid professions in South Korea, oppose the recruitment plan because they worry they would face greater competition and lower income. 

Striking doctors have said they worry doctors faced with increased competition would engage in overtreatment, burdening public medical expenses.
