CAPE CANAVERAL, Fla. — A private U.S. lunar lander reached the moon and eased into a low orbit Wednesday, a day before it will attempt an even greater feat — landing on the gray, dusty surface.

A smooth touchdown would put the U.S. back in business on the moon for the first time since NASA astronauts closed out the Apollo program in 1972. The company, if successful, also would become the first private outfit to ace a moon landing.

Launched last week, Intuitive Machines’ lander fired its engine on the back side of the moon while out of contact with Earth. Flight controllers at the company’s Houston headquarters had to wait until the spacecraft emerged to learn whether the lander was in orbit or hurtling aimlessly away.

Intuitive Machines’ Mission

Intuitive Machines confirmed its lander, nicknamed Odysseus, was circling the moon with experiments from NASA and other clients. The lander is part of a NASA program to kickstart the lunar economy; the space agency is paying $118 million to get its experiments on the moon on this mission.

On Thursday, controllers will lower the orbit from just under 60 miles (92 kilometers) to 6 miles (10 kilometers) — a crucial maneuver occurring again on the moon’s far side — before aiming for a touchdown near the moon’s south pole. It’s a dicey place to land with all the craters and cliffs, but deemed prime real estate for astronauts since the permanently shadowed craters are believed to hold frozen water.

Previous Moon Missions

The moon is littered with wreckage from failed landings. Some missions never even got that far. Another U.S. company — Astrobotic Technology — tried to send a lander to the moon last month, but it didn’t get there because of a fuel leak. The crippled lander came crashing back through the atmosphere, burning up over the Pacific.

A rundown on the moon’s winners and losers:

First Victories

The Soviet Union’s Luna 9 successfully touches down on the moon in 1966, after its predecessors crash or miss the moon altogether. The U.S. follows four months later with Surveyor 1. Both countries achieve more robotic landings, as the race heats up to land men.

Apollo Rules

NASA clinches the space race with the Soviets in 1969 with a moon landing by Apollo 11’s Neil Armstrong and Buzz Aldrin. Twelve astronauts explore the surface over six missions, before the program ends with Apollo 17 in 1972. Still the only country to send humans to the moon, the U.S. hopes to return crews to the surface by the end of 2026 or so, a year after a lunar fly-around by astronauts.

China Emerges

China, in 2013, becomes the third country to successfully land on the moon, delivering a rover named Yutu, Chinese for jade rabbit. China follows with the Yutu-2 rover in 2019, this time touching down on the moon’s unexplored far side — an impressive first. A sample return mission on the moon’s near side in 2020 yields nearly 4 pounds (1.7 kilograms) of lunar rocks and dirt. Another sample return mission should be launching soon, but this time to the far side. Seen as NASA’s biggest moon rival, China aims to put its astronauts on the moon by 2030.

Russia Stumbles

In 2023, Russia tries for its first moon landing in nearly a half-century, but the Luna 25 spacecraft smashes into the moon. The country’s previous lander — 1976’s Luna 24 — not only landed, but returned moon rocks to Earth.

India Triumphs on Take 2

After its first lander slams into the moon in 2019, India regroups and launches Chandrayaan-3 (Hindi for moon craft) in 2023. The craft successfully touches down, making India the fourth country to score a lunar landing. The win comes just four days after Russia’s crash-landing.

Japan Lands Sideways

Japan becomes the fifth country to land successfully on the moon, with its spacecraft touching down in January. The craft lands on the wrong side, compromising its ability to generate solar power, but manages to crank out pictures and science before falling silent when the long lunar night sets in.

Private Tries

A privately funded lander from Israel, named Beresheet, Hebrew for “in the beginning,” crashes into the moon in 2019. A Japanese entrepreneur’s company, ispace, launches a lunar lander in 2023, but it, too, wrecks. Astrobotic Technology, a Pittsburgh company, launches its lander in January, but a fuel leak prevents a landing and dooms the craft. Astrobotic and Intuitive Machines plan more moon deliveries.
