Beyond Quotes

“Carl Sagan put it best: Extraordinary claims require extraordinary evidence.”
― Chris Impey, Beyond: Our Future in Space

“The Moon’s low gravity and slow rotation mean that a space elevator could be built with materials already available. The honeycomb fiber called M5 is lighter and stronger than Kevlar; a ribbon 3 centimeters wide and 0.02 millimeter thick could support 2,000 kilograms on the lunar surface or 100 climbers with a mass of 600 kilos each, evenly spaced along the ribbon. We could build a lunar elevator right now.”
