Mission in Jeopardy: Peregrine Lander Faces Critical Fuel Leak En Route to the Moon

Peregrine Lander Faces Critical Fuel Leak En Route To The Moon

The Peregrine Lander, an ambitious project from the American company Astrobotic, is facing critical challenges mere days after its launch towards the Moon. Based in Pittsburgh, Astrobotic initiated this mission with the objective of achieving a soft landing on the lunar surface. However, the situation has rapidly deteriorated due to a fuel leak in the Peregrine lander, jeopardizing the mission’s success and potentially reducing the mission’s lifespan to mere hours.

The leak has caused significant difficulties in maintaining the spacecraft’s stability, as it struggles to keep its solar panels oriented towards the Sun. This orientation is crucial for powering the spacecraft. Astrobotic has stated that the current priority is to guide Peregrine as close to the Moon as possible before it loses its ability to maintain this critical sun-pointing position, which would result in a complete loss of power.

Launched from Cape Canaveral in Florida, the 1.2-tonne Peregrine lander aimed to land in the Moon’s northern hemisphere by late February. This mission was particularly significant for NASA, the United States space agency, which had planned to use the lander to deploy five instruments for studying the lunar surface. These studies were intended as a precursor to future astronaut missions later in the decade.

Troubles for Peregrine began almost immediately post-launch, as it detached from the launch rocket. Engineers monitoring the mission observed issues with the lander’s ability to maintain its solar panels facing the Sun. This problem was swiftly attributed to a substantial leak in the propulsion system, causing Peregrine to misalign.

To counteract this misalignment, the lander’s thrusters are being used extensively, leading to an accelerated consumption of the already limited fuel supply. Astrobotic estimates that the lander has less than two days of propellant remaining. Once depleted, Peregrine will lose its orientation, causing the solar panels to cease collecting sunlight and the spacecraft to rapidly lose power.

This mission forms part of a broader initiative by NASA, involving private-public partnerships with commercial entities. Astrobotic, along with two other companies – Intuitive Machines and Firefly – have been contracted by NASA to undertake six missions to the Moon in 2024. While NASA acts as a customer in these endeavors, it does not oversee these missions directly. Each company is responsible for the design and command of their respective spacecraft.

NASA’s approach with these partnerships aims to foster innovation and reduce costs in lunar exploration. The agency acknowledges the possibility of mission failures but remains optimistic about the long-term benefits of this model. As expressed by NASA’s deputy administrator, Pam Melroy, the agency’s partnership with commercial ventures allows for a higher risk tolerance. The idea is that even in the event of a mission’s failure, subsequent missions will learn from these experiences and eventually succeed. This strategy, according to Melroy, could lead to more cost-effective and frequent lunar exploration missions in the future.
