The Earth's Moon is a treasure trove of mineral resources, such as precious metals, rare earth elements, Helium-3 and oxygen for propellants. However, the cost of landing on the Moon is currently very high. Using modern fibers we can build a lunar elevator which reduces the cost of lunar landing sixfold. Furthermore, it makes the cost of collecting material from the Moon and sending it to Earth essentially free. The lunar elevator will pay for itself after nineteen payload cycles. The lunar elevator represents a game changing technology which will open up the Moon to commercial mining.
Charles Radley is President of the Oregon L5 Society, and an Associate Fellow of the AIAA. He has worked extensively in the space industry since 1981 as a product assurance and systems engineer. He is an adviser to Liftport Group.

A very nice lunar elevator study report from Israel. Student Project at The Technion, Israel, 2008. A full year under the supervision of Dr Alexander Kogan, now retired to Canada. The team is now disbanded, some work at the Israeli Aerospace Industries.
• Cargo delivery from the Moon to the Earth can
be done within 6 days using solar power and no
• The cargo system uses a cable car moving
along a stretched ribbon.
• The ribbon is kept stretched by terrestrial and
lunar gravity. One end is anchored on the Moon
and the other one free.
• The cargo released from the cable car performs
a passive flight to the Earth. At landing, no
parachute is needed.
