NASA's NuSTAR Telescope Unfurls 10-meter Mast

摘要

New York Nasa's newest space telescope - a black hole-hunting observatory - unfolded a giant mast in orbit June 21, one of the final steps before it can begin peering deep into the universe. The $165 million Nuclear Spectroscopic Telescope Array (NuSTAR) is an X-ray observatory designed to study some of the most energetic and mysterious places in the universe through X-ray light. NuSTAR's 10-meter mast, made of stack-able cubes formed by carbon fiber rods, serves to distance the telescope's two X-ray optics from the focal point where its camera is placed.
