The method involves building lenses out of liquid polymers — while in space.
"In microgravity, liquids take on shapes that are useful for making lenses and mirrors, so if we make them in space, they could be used to build telescopes that are dramatically bigger than was previously thought possible," Edward Balaban, a researcher at NASA's Ames Research Center and FLUTE's principal investigator, said in a"This method allows us to completely skip any mechanical processes such as grinding or polishing," Moran Bercovici, an associate professor of...
The research team, which comprises scientists from NASA's Ames Research Center, NASA’s Goddard Space Flight Center, and the Technion - Israel Institute of Technology, has already demonstrated the technology closer to home, first in simulated microgravity in water on Earth, then on ZeroG parabolic flights, which offered researchers 15- to 20-second-long periods of microgravity.

Giant Space Telescopes Could Be Made Out of Liquid - Universe TodayThe Hubble space telescope has a primary mirror of 2.4 meters. The Nancy Grace Roman telescope has one at 2.4 meters and the James Webb Space Telescope has a whopping 6.5 meter primary mirror. These are all fine and well to get the job done that they were designed for, but what if… we could … Continue reading 'Giant Space Telescopes Could Be Made Out of Liquid'
