Moon Space Elevator Emerging as Practical Cis-Lunar Transportation Solution
As supply chain disruptions of LOX and LN2 create launch delays amid medical crisis, limitations of chemical propulsion generally (availability, risk, environmental effects) have prompted industry and academic thought leaders to conceptualize space ‘elevator’ as infrastructure alternative, championed by International Space Elevator Consortium; Moon-based elevators take advantage of low gravity, allowing use of conventional materials: Lunar Space Elevator (LiftPort / Michael Laine) and Spaceline (Columbia University); Hybrid concept Sky Ladder (CALT / Wang Xiaojun) would utilize tethered spaceports attached to both Earth and Moon at 4% cost of rocket-based transit
