Honeycomb Mirrors Makes NASA’s Webb the Most Powerful Space Telescope NASA/Chris Gunn

NASA’s James Webb Space Telescope requires a primary mirror so large that it would not fit inside any existing rockets as one single, large mirror.  Because of this, Webb is equipped with a revolutionary set of 18 hexagonal mirror segments that are able to fold to fit inside the rocket fairing. Their honeycomb like arrangement allows for Webb to have the largest possible reflective surface area to make observations, with the least amount of dead space in between each.
