An American company has made history by becoming the first commercial company to put a spacecraft on the Moon.
Houston-based Intuitive Machines landed its Odysseus robot near the lunar south pole, breaking the USA’s absence from the moon since 1972’s Apollo mission.
This represent an important moment not just for the commercial exploitation of space but for the US space program in general.
Nasa purchased room on Odysseus for six scientific instruments, and its administrator Bill Nelson was quick to congratulation Intuitive Machines for a „triumph”.
„The US has returned to the Moon”, he said. „Today, for the first time in the history of humanity, a commercial company – an American company – launched and led the voyage up there. And today is the day that shows the power and promise of Nasa’s commercial partnerships.”
Controllers had to deal with an almost mission-stopping technical problem even before the descent began: Odysseus’ ranging lasers, which were supposed to calculate the craft’s altitude and velocity, weren’t working properly.
Fortunately, there were some experimental lasers from Nasa on board, and engineers were able to patch these across to the navigation computers.
Odysseus touched down at 23:23 GMT. At first, there was no signal at all from the robot. There were plenty of nerves as the minutes ticked by, but eventually a communications link was made, albeit a faint one.
This led to some concerns about the status of the lander. Within a couple of hours, however, Intuitive Machines was reporting that Odysseus was standing upright and sending back data, including pictures.
The targeted landing site was a cratered terrain next to a 5km-high mountain complex known as Malapert – the southernmost point on the Moon ever visited by a spacecraft, at 80 degrees South.
Malapert is on the shortlist of locations where Nasa is considering sending astronauts later this decade as part of its Artemis program.
There are some deep craters in this region that never see any sunlight (being permanently in shadow) and scientists think frozen water could be inside them, says the BBC.
„The ice is really important because if we can actually take advantage of that ice on the surface of the Moon, that’s less materials we have to bring with us”, explained Lori Glaze, Nasa’s director of planetary science.
„We could use that ice to convert it to water – drinkable drinking water – and we can extract oxygen and hydrogen for fuel and for breathing for the astronauts. So it really helps us in human exploration.”
Nasa’s six payloads on board Odysseus are a mix of technology demonstration and science.
A key investigation will be one looking at the behaviour of lunar dust, which the Apollo astronauts found to be a serious nuisance, as scratched and clogged equipment.
The agency’s scientists want to understand better how the dust is kicked up by landing craft to hang just above the surface before then settling back down.
The six commercial payloads on board include a student camera system from Embry-Riddle Aeronautical University, which should have been deployed from Odysseus when it was still 30m above the lunar surface.
This system was designed to take selfie images as the robot set itself down.
American artist Jeff Koons has also attached a box to the side of the lander that contains 125 small stainless steel balls to represent the Moon’s different phases through a month.
