Astrobotic's Peregrine: A Tale of Setbacks and Triumphs in Space Exploration

 Last week, Peregrine One, a US spacecraft on a mission to land on the Moon, faced a propulsion fault that dashed hopes of a lunar touch-down. The operator, Astrobotic, based in Pittsburgh, decided to command Peregrine to destroy itself, directing it into Earth's atmosphere for a fiery end. A tracking station in Canberra, Australia, confirmed the loss of signal with Peregrine at 20:59 GMT.

Anticipated to leave little or no remains intact to the ocean surface, even if they did, the impact was expected far away from any population. Astrobotic's ambitious goal was to deliver five NASA instruments to the Moon's surface to study the local environment ahead of astronauts' return later this decade.

Had Peregrine successfully landed, it would have marked the first American mission in half a century to do so and the first-ever private venture to achieve such a feat. To date, controlled lunar landings have been achieved only by government agencies from the US, the Soviet Union, China, and India.

However, Astrobotic's mission faced challenges from the moment it left the launch rocket on January 8. Despite the troubles, the team found solace in the accomplishments achieved under difficult circumstances, with Peregrine continuing to operate in space for over 10 days. Engineers diagnosed the propulsion fault, extending the lander's life beyond initial expectations.

Sian Cleaver, Airbus' Orion European Service Module industrial manager, emphasized the positive aspects of the mission, stating, "Space exploration is a learning game... we should look at this as an incredible engineering success." She highlighted the teamwork that turned the mission around from appearing doomed to restoring some spacecraft capabilities and ultimately directing it back to Earth.

The fault was traced to leaking propellant from a ruptured oxidizer tank, causing thrust and hindering the craft from maintaining solar panels' constant alignment with the Sun, crucial for power supply. Astrobotic shared a video on social media showing Peregrine's view of Earth before its demise.

The Astrobotic team worked on Peregrine's thrusters to restore stable pointing, depleting the oxidizer even further. Despite the challenges, the onboard payloads were activated, proving their space-worthiness. Some instruments, like the Peregrine Ion Trap Mass Spectrometer (PITMS), developed in the UK, performed well in check-out tests, offering the potential for future lunar missions.

Astrobotic, the first of three US companies in a new private-public partnership with NASA, plans to send a lander to the Moon this year. The agency is collaborating with Pittsburgh firm Intuitive Machines and Firefly, aiming for a total of six lunar surface missions in 2024.

Astrobotic will have another opportunity in the latter half of the year when it attempts to land a NASA rover called Viper. Intuitive Machines' first attempt is expected to launch next month, targeting the lunar south pole. Before that, the Japanese space agency will attempt a safe landing near the near-equatorial impact crater Shioli, scheduled for 15:20 GMT on Friday. The journey of space exploration continues, with setbacks turning into valuable lessons and triumphs paving the way for future missions.
