NASA assesses micrometeoroid impact on James Webb mirror segment

Webb’s primary mirror is made up of 18 hexagonal gold-coated beryllium segments that must be aligned to within a tiny fraction of the width of a human hair to achieve a sharp focus. This photo shows the mirror during pre-launch preparations with the telescope’s secondary mirror folded away for flight. Credit: NASA A high-speed dust-size micrometeoroid slammed into one of ...

Webb is Cool, but it Still Needs to get Cooler

Cooling things down in space is trickier than it might sound.  But that is exactly the process the James Webb telescope is going through right now.  Getting down to cryogenic temperature is imperative for its infrared imaging systems to work correctly.  While the telescope has already started, it will be another few weeks before the process is complete, and it’s ...

Engineers pleased with Webb’s progress as mirror alignment gets underway

STORY WRITTEN FOR  & USED WITH PERMISSION This “selfie” was created using a specialized pupil imaging lens inside of the NIRCam instrument that was designed to take images of the primary mirror segments instead of images of space. This configuration is not used during scientific operations and is used strictly for engineering and alignment purposes. In this case, the bright segment ...
