Private US lander bound for the Moon

WASHINGTON: A private US spaceship was bound for the Moon on Thursday, where it will attempt to land near the south pole and carry out experiments that pave the way for the return of American astronauts later this decade. Intuitive Machines, the Houston-based company leading mission “IM-1,” hopes to become the first non-government entity to achieve a soft touchdown on our celestial companion, and to land the first US robot on the surface since the Apollo missions more than five decades ago.

A previous attempt by another US company last month ended in failure, raising the stakes to get it right this time and demonstrate the strength of American industry. Intuitive Machines’ hexagonal-shaped Nova-C lander named “Odysseus” blasted off from the Kennedy Space Center in Florida on top of a SpaceX Falcon 9 rocket at 1:05 am local time (0605 GMT). “We are keenly aware of the immense challenges that lie ahead,” CEO Steve Altemus said in a news release, confirming Odysseus had successfully established contact with ground control and all systems were working normally.

The spaceship, which carries a powerful new type of engine based on supercooled liquid methane and oxygen should reach its landing site, Malapert A, on Feb 22, an impact crater 300 km from the south pole. NASA hopes to eventually build a long-term presence and harvest ice there for both drinking water and rocket fuel under Artemis, its flagship Moon-to-Mars program.

The agency paid Intuitive Machines $118 million to ship science hardware to better understand and mitigate

environmental risks for astronauts, the first of whom are scheduled to land no sooner than 2026. Instruments include cameras to investigate how the lunar surface changes as a result of engine plume kicking up dust and a device to analyze the charged dust haze that appears during lunar twilight as a result of solar radiation.

Odysseus also carries an advanced landing system that uses laser pulses to detect hazards like small boulders and craters. There is more colorful cargo aboard as well, including a digital archive of human knowledge and 125 mini-sculptures of the Moon by the artist Jeff Koons. After touchdown, the payloads are expected to run for roughly seven days before lunar night sets in on the south pole, with the lack of solar power rendering Odysseus inoperable.

IM-1 is the second mission under a NASA initiative called Commercial Lunar Payload Services (CLPS), which the space agency created to delegate cargo services to the private sector to achieve savings and to stimulate a wider lunar economy. Four more CLPS launches are expected this year. The first, by Pittsburgh-based Astrobotic, launched in January, but its Peregrine spacecraft experienced an engine anomaly that caused a fuel leak and it was eventually brought back to burn up in Earth’s atmosphere.

Soft-landing a robot on the Moon is challenging because it has to navigate treacherous terrain with communications subject to a lag of several seconds, and use its thrusters for a controlled descent in the absence of an atmosphere that would support parachutes. Apart from Astrobotic’s failed attempt, two other private initiatives got close. The Soviet Union was the first country to touch down, then the United States, which is still the only country to also put people on the surface.
