Review Outlines Technical Roadmap for Kilometre-Scale Lunar Optical Hypertelescopes
What Was Observed (Empirical Data)
This paper conducts a historical and technical review of lunar-based astronomical observatory concepts from the Apollo era to the present, rather than reporting new observational measurements. The authors evaluate how advances in autonomous robotics, additive manufacturing, precision optics, and formation flying could enable diluted optical arrays spanning hundreds of meters to several kilometres on the lunar surface.
The Reality Check (Anti-Hype Analysis)
No lunar hypertelescope is currently funded, under construction, or approved for launch, and the proposed architecture remains a conceptual roadmap. While the Moon lacks atmospheric distortion and provides high mechanical stability, previous lunar observatory proposals consistently failed due to high operational costs, engineering complexity, and shifting scientific priorities.
