The 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'
Enter the idea for using fluids to create lenses in space that are 10x – 100x bigger. And the time it would take to make them would be significantly less than a glass-based lens.
FLUTE, or the Fluidic Telescope Experiment is run by principal investigator Edward Balaban at Ames Research Center in California’s Silicon Valley. The experiment is being collaborated on by researchers at Ames at the Goddard Space Flight Center in Greenbelt, Maryland along with researchers from Technion, the Israeli Institute of Technology.
Next the team took flight on two ZeroG parabolic flights to further test the process. Synthetic oils of varying viscosities were used to determine which would work better. These oils were pumped into circular frames about the size of a dollar coin while the plane was in freefall and again they were able to make free-standing liquid lenses, though once the plane started lifting up again and the effects of gravity were felt the liquids lost their shape.
