GREENBELT, Md. (NASA PR) — Webb continues on its path to becoming a focused observatory. The team has successfully worked through the second and third out of seven total phases of mirror alignment. With the completion of these phases, called Segment Alignment and Image Stacking, the team will now begin making smaller adjustments to the positions of Webb’s mirrors.

Teledyne Imaging’s Infrared Sensors Launched Aboard the James Webb Space Telescope

For the last time on Earth, the James Webb Space Telescope’s sunshield was deployed and tensioned by testing teams at Northrop Grumman in Redondo Beach, California where final deployment tests were completed. Webb’s sunshield is designed to protect the telescope from light and heat emitted from the sun, Earth, and moon, and the observatory itself. (Credit: NASA/Chris Gunn)

Teledyne’s infrared detectors are the “eyes” of the world’s most advanced space telescope

THOUSAND OAKS, Calif. (Teledyne Technologies PR) — Teledyne Technologies Incorporated (NYSE:TDY) congratulates NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA) on the successful launch of the James Webb Space Telescope (JWST). Teledyne provided 15 extremely sensitive H2RG infrared detectors that are used in three of the four science instruments of JWST: the Near-Infrared Camera (NIRCam), the Fine Guidance Sensor (FGS), and the Near-Infrared Spectrograph (NIRSpec). Ten Teledyne detectors in NIRCam will study the structure and morphology of the universe. Three Teledyne detectors in FGS will be used to point and stabilize the telescope. Two Teledyne detectors in NIRSpec will reveal information about chemical composition, temperature, and velocity of what JWST observes. Teledyne also provided the SIDECAR ASIC focal plane electronics that operate the H2RG detectors.
