How do you get power into your lunar base? With a tower of concrete several kilometers high

It sounds like science fiction, but building an enormous tower several kilometers high on the lunar surface may be the best way to harness solar energy for long-term lunar exploration. Such towers would raise solar panels above obstructing geological features on the lunar surface, and expand the surface area available for power generation.

Engineers propose solar-powered lunar ark as ‘modern global insurance policy’

University of Arizona researcher Jekan Thanga is taking scientific inspiration from an unlikely source: the biblical tale of Noah’s Ark. Rather than two of every animal, however, his solar-powered ark on the moon would store cryogenically frozen seed, spore, sperm and egg samples from 6.7 million Earth species.

An astronaut’s guide to out-of-Earth manufacturing

mprovising new stuff from the stuff you have is part of an astronaut’s job description—think Apollo 13’s crew refitting CO2 filters to save their own lives, or stranded Mark Watney in The Martian, feeding himself on the Red Planet. Now plans are underway to manufacture items in orbit, and ESA astronaut Alexander Gerst argues this could make a big difference to…

Engineering marvel: Sixth mirror cast for Giant Magellan Telescope

The Giant Magellan Telescope announces fabrication of the sixth of seven of the world’s largest monolithic mirrors. These mirrors will allow astronomers to see farther into the universe with more detail than any other optical telescope before. The sixth 8.4-meter (27.5 feet) mirror—about two stories high when standing on edge—is being fabricated at the University of Arizona’s Richard F. Caris Mirror…
