NASA begins process of bringing new space telescope into focus

NASA on Wednesday embarked on a months-long, painstaking process of bringing its newly launched James Webb Space Telescope into focus, a task due for completion in time for the revolutionary eye in the sky to begin peering into the cosmos by early summer. Mission control engineers at NASA's Goddard Space Flight Center in Greenbelt, Maryland, began by sending their initial commands to tiny motors called actuators that slowly position and fine-tune the telescope's principal mirror. Consisting of 18 hexagonal segments of gold-plated beryllium metal, the primary mirror measures 21 feet 4 inches (6.5 m) in diameter - a much larger light-collecting surface than Webb's predecessor, the 30-year-old Hubble Space Telescope. The 18 segments, which had been folded together to fit inside the cargo bay of the rocket that carried the telescope to space, were unfurled with the rest of its structural components during a two-week period following Webb's launch on Dec. 25. Those segments must now be detached from fasteners that held them in place for the launch and then moved forward half an inch from their original configuration - a 10-day process - before they can be aligned to form a single, unbroken, light-collecting surface. The alignment will take
