DARPA has finished developing their Space Surveillance Telescope (SST) and is formally transferring the innovative telescope to the U.S. Air Force. The SST has already been a game-changer for space situational awareness and is helping prevent potential collisions with satellites or Earth. The telescope also will continue to give NASA and the scientific community surveillance data on events like supernovas and potentially hazardous near-Earth asteroids. It uses the most steeply curved primary telescope mirror ever made, and the mirror lets the telescope collect more light to see images across a wider field of view than any other space surveillance telescope. The innovative design of SST allows for a short focal length, wide field of view, and a compact optical train. SST’s camera also has the world’s fastest telescope camera shutter and takes thousands of pictures a night.
