SONDERKOLLOQUIUM: The James Webb Space Telescope: The First Light Machine

Prof. H. Philip Stahl, Space Optics Manufacturing Technology Center NASA Marshall Space Flight Center, AL 35812

Scheduled to begin its 10 year mission after 2018, the James Webb Space Telescope (JWST) will search for the first luminous objects of the Universe to help answer fundamental questions about how the Universe came to look like it does today. At 6.5 meters in diameter, JWST will be the world’s largest space telescope. This talk reviews science objectives for JWST and how they drive the JWST architecture, e.g. aperture, wavelength range and operating temperature. Additionally, the talk provides an overview of the JWST primary mirror technology development and fabrication status.

Biography: Dr. H. Philip Stahl is a Senior Optical Physicist at NASA Marshall Space Flight Center currently leading a study to mature mirror technologies for a new large aperture UV/Optical/IR telescope to replace Hubble. Previously, he was responsible for developing candidate primary mirror technologies for the James Webb Space Telescope. Dr. Stahl is a leading authority in optical metrology, optical engineering, and phase-measuring interferometry. Many of the world\'s largest telescopes have been made with the aid of high-speed and infrared phase-measuring Interferometers developed by him. He is a Fellow of SPIE, past ICO Vice President and 2014 SPIE President. He earned his PhD in Optical Science at the University of Arizona in 1985.
