On 27 February 2025, the Intuitive Machines IM-2 Moon Lander, named Athena, was launched to investigate the presence and quantity of lunar water ice. The spacecraft reached the surface of the Moon on 6 March 2025. However, the landing was unsuccessful, resulting in the lander coming to rest on its side and causing some onboard equipment to become nonoperational.
Reason For The IM-2 Moon Lander Failure Revealed
Steve Altemus, the CEO of Intuitive Machines, revealed several factors contributing to the IM-2 Moon Lander’s landing failure during the first quarter earnings report.
These issues have been identified by Intuitive Machines’ internal teams working with independent reviewers and external experts. These included interference from the laser altimeter during descent, challenges posed by the Moon’s terrain and lighting conditions, and issues with crater recognition tuning.
With a clear understanding of the reason behind the failure, Intuitive Machines is ready to make improvements ahead of the next Moon landing attempt. The IM-3 mission is currently in development and will launch in the first half of 2026.
Similar issues affected the IM-1 mission, resulting in its failure, paralleling the challenges faced by IM-2. The upcoming IM-3 mission will serve as a testbed for these improvements, aiming to ensure a successful lunar landing.
How Does Intuitive Machine Aim To Fix The IM-2 Moon Lander
To address these challenges, Altemus highlighted plans to integrate dissimilar and redundant altimeters into the IM-3 mission’s sensor suite. Rigorous testing under extreme conditions will validate the effectiveness of these additions.
Furthermore, the IM-3 mission will introduce a lighting-independent sensor for surface velocity measurements and expand the terrain crater database to enhance lunar navigation capabilities. Data gathered during the IM-2 mission’s operations at the Moon’s South Pole will also contribute to refining machine learning algorithms for improved navigation accuracy.
