• US returns to the moon in a first for private sector

  LUNAR STRATEGY: NASA hopes to eventually build a long-term presence and harvest polar ice for both drinking water and rocket fuel for a journey to Mars

  For the first time since the Apollo era, a US spaceship has landed on the moon — an uncrewed commercial robot, funded by NASA to pave the way for US astronauts to return to Earth’s cosmic neighbor later this decade.

  Odysseus, built by Houston, Texas-based Intuitive Machines, touched down near the lunar south pole on Thursday after a nail-biting final descent where flight controllers had to switch to an experimental landing system and took several minutes to establish radio contact with the lander after it came to rest.

  “Today for the first time in more than a half century, the US has returned to the moon,” NASA Administrator Bill Nelson said in a video. “Today for the first time in the history of humanity, a commercial company, an American company, launched and led the voyage up there.”

  “After troubleshooting communications, flight controllers have confirmed Odysseus is upright and starting to send data,” Intuitive Machines said on social media. “Right now, we are working to downlink the first images from the lunar surface.”

  A previous moonshot by another US company last month ended in failure, raising the stakes to demonstrate that private industry had what it took to repeat a feat last achieved by NASA during its manned Apollo 17 mission in 1972.

  Underscoring the technical challenges, an onboard navigation system failed and Odysseus instead flew the final leg of its trip using an experimental laser guidance system developed by NASA to run only as a technology demonstration.

  Confirmation of the landing was supposed to come seconds after the milestone, but instead nearly 15 minutes passed as announcers mused whether the craft had come down “off angle.”

  Finally, Intuitive Machines chief technology officer Tim Crain confirmed “our equipment is on the surface of the moon and we are transmitting,” as applause broke out at mission control.

  Odysseus touched down in Malapert A, an impact crater 300km from the lunar south pole.

  NASA hopes to eventually build a long-term presence and harvest polar ice for both drinking water and rocket fuel for an onward journey to Mars under Artemis.

  The current mission is “one of the first forays into the south pole to actually look at the environmental conditions to a place we’re going to be sending our astronauts in the future,” senior NASA official Joel Kearns said.

  NASA’s first crewed mission to the region is scheduled for no sooner than 2026. The US’ geopolitical rival China is also planning to send its first crew to the moon in 2030, ushering in a new era of space competition.

  Odysseus, which is about the size of a large golf cart, launched from Florida on Thursday last week on a SpaceX Falcon 9 rocket.

  It carries six NASA science instruments, including cameras to investigate how the lunar surface changes as a result of the engine plume from a spaceship, and a device to analyze clouds of charged dust particles that hang over the surface at twilight as a result of solar radiation.

  The rest of the cargo was shipped on behalf of Intuitive Machines’ private clients, and includes 125 stainless steel mini moons by artist Jeff Koons.

  The cargo can run for up to seven days before lunar night occurs, rendering Odysseus inoperable.

  NASA paid Intuitive Machines US$118 million to ship its hardware under a new initiative called Commercial Lunar Payload Services (CLPS), which it created to delegate cargo services to the private sector to achieve savings and stimulate a wider lunar economy.

  The first CLPS mission, by Pittsburgh, Pennsylvania-based Astrobotic, launched last month, but its Peregrine spacecraft sprung a fuel leak and was eventually brought back to burn up in Earth’s atmosphere.

  Spaceships landing on the moon must navigate treacherous terrain and rely on thrusters to control their descent in the absence of an atmosphere.

  Until now, only the space agencies of the Soviet Union, the US, China, India and Japan had accomplished the feat.
