Peregrine Lander: US Moon Mission Ends in Destruction Over the Pacific Ocean

 

Last week, a US spacecraft on a mission to land on the Moon faced a tragic end, meeting destruction over the Pacific due to a propulsion fault.

The spacecraft, Peregrine One, operated by the private company Astrobotic based in Pittsburgh, had to abandon its lunar landing mission and was commanded to self-destruct. The failure occurred shortly after its launch on January 8.

The spacecraft's mission was to deliver five instruments provided by NASA to study the Moon's surface and environment in preparation for future astronaut missions. Had it succeeded, Peregrine One would have marked the first successful American moon landing in 50 years and the first ever by a private venture.

Unfortunately, trouble plagued the mission from the beginning. The spacecraft faced a propulsion fault, later identified as leaking propellant from a ruptured oxidizer tank. This caused the craft to lose stability, preventing it from keeping its solar panels aligned with the Sun, crucial for maintaining power.

Despite the setback, Astrobotic managed to operate Peregrine for more than 10 days in space, far exceeding initial expectations. Engineers diagnosed the issue and, through ingenuity, extended the lander's operational life.

The fault didn't deter the activation of onboard payloads, proving their capability in space. Some instruments even gathered data on the radiation environment between Earth and the Moon.

Sian Cleaver, Airbus' Orion European Service Module industrial manager, emphasized the mission's engineering success despite its challenges during an interview with the BBC's Today Programme. She highlighted the collaborative effort of engineers and scientists who worked together to troubleshoot and redirect the spacecraft back to Earth.

The Peregrine Ion Trap Mass Spectrometer (PITMS), one of the NASA instruments with its sensor and electronics developed in the UK, performed well in tests. Although the mission faced adversity, the technology may have another chance in upcoming lunar missions.

In the face of setbacks, the Peregrine mission showcased the complexities of space exploration. While the lunar landing didn't materialize, the resilience and problem-solving abilities demonstrated by the team underscore the continual learning process in space exploration. The mission's legacy lies not in failure but in the remarkable achievements amid adversity, proving that space travel is indeed a challenging endeavor.
