A spacecraft built and flown by Texas-based company Intuitive Machines LUNR.O landed near the south pole of the moon on Thursday, the first US touchdown on the lunar surface in more than half a century and the first ever achieved entirely by the private sector.

The six-legged robot lander, dubbed Odysseus, touched down at about 6:23 pm EST (2323 GMT), the company and NASA commentators said in a joint webcast of the landing from Intuitive Machines’ mission operations center in Houston.
As planned, the spacecraft was believed to have come to rest at a crater named Malapert A near the moon‘s south pole, according to the webcast.
The landing, one day after the spacecraft reached lunar orbit and a week after its launch from Florida, was confirmed by signals beamed back some 239,000 miles (384,000 km) to mission control.
But communication with the vehicle took several minutes to re-establish, and the initial signal was faint, leaving mission control uncertain as to the precise condition and position of the lander, according to flight controllers heard in the webcast.
The spacecraft was not designed to provide live video of the event.
Touchdown came after an 11th-hour glitch with the spacecraft‘s autonomous navigation system that required engineers on the ground to employ a work-around solution.
The vehicle is carrying a suite of scientific instruments and technology demonstrations for NASA and several commercial customers designed to operate for seven days on solar energy before the sun sets over the polar landing site.
The NASA payload will focus on collecting data on space weather interactions with the moon’s surface, radio astronomy and other aspects of the lunar environment for future landers and NASA’s planned return of astronauts later in the decade.
The uncrewed IM-1 mission was sent on its way to the moon on Wednesday atop a Falcon 9 rocket launched by Elon Musk’s company SpaceX from NASA’s Kennedy Space Center in Cape Canaveral, Florida.
Thursday’s landing represented the first controlled descent to the lunar surface by a U.S. spacecraft since Apollo 17 in 1972, when NASA’s last crewed moon mission landed there with astronauts Gene Cernan and Harrison Schmitt.
To date, spacecraft from just four other countries have ever landed on the moon – the former Soviet Union, China, India and, mostly recently, just last month, Japan. The United States is the only one ever to have sent humans to the lunar surface.
Dawn of ArtemisÂ
The arrival of Odysseus also marks the first “soft landing” on the moon ever by a commercially manufactured and operated vehicle and the first under NASA’s Artemis lunar program, as the US races to return astronauts to Earth’s natural satellite before China lands its own crewed spacecraft there.
NASA aims to land its first crewed Artemis in late 2026 as part of long-term, sustained lunar exploration and a stepping stone toward eventual human flights to Mars. The initiative focuses on the moon’s south pole in part because a presumed bounty of frozen water exists there that can be used for life support and production of rocket fuel.
A host of small landers like Odysseus are expected to pave the way under NASA’s Commercial Lunar Payload Services (CLPS) program, designed to deliver instruments and hardware to the moon at lower costs than the U.S. space agency’s traditional method of building and launching those vehicles itself.
Leaning more heavily on smaller, less experienced private ventures comes with its own risks.
Just last month the lunar lander of another firm, Astrobotic Technology, suffered a propulsion system leak on its way to the moon shortly after being placed in orbit on Jan. 8 by a United Launch Alliance (ULA) Vulcan rocket making its debut flight.
The malfunction of Astrobotic’s Peregrine lander marked the third failure of a private company to achieve a lunar touchdown, following ill-fated efforts by companies from Israel and Japan.
Although Odysseus is the latest star of NASA’s CLPS program, the IM-1 flight is considered an Intuitive Machines mission. The company was co-founded in 2013 by Stephen Altemus, former deputy director of NASA’s Johnson Space Center in Houston and now the company’s president and CEO.
The proliferation of commercial space ventures has itself been driven by leaps in technology in recent decades.
The Apollo program and robot lunar Surveyor missions that preceded it flew at the very dawn of the computer age, before the advent of modern microchips, electronic sensors and software, or the development of super light-weight metal alloys and myriad other advances that have spurred a revolution in spaceflight.
