The Nationwide Area Society and the Huntsville Alabama L5 (HAL5) Society invitations you to a free Area discussion board:
The Webb Area Telescope: The First Gentle Machine
Thursday, January 13, 202, 8:00 pm to 9:15 pm EST
With Particular Visitor Dr. H. Philip Stahl, Senior Optical Physicist, NASA Marshall Area Flight Heart
On Christmas Day 2021, the Webb Area Telescope (WST) was launched from Arianespace’s ELA-3 launch advanced at Europe’s Spaceport situated close to Kourou, French Guiana, on an Ariane 5 rocket. This was the start of its 29-day, million mile journey out to the second Earth-Solar Lagrange level (L2). From L2 the WST will start its 10-year mission to seek for the primary luminous objects of the universe to assist reply elementary questions on how the Uuniverse got here to seem like it does immediately, together with formation of galaxies and protoplanetary programs.
With a 6.5-meter diameter mirror, the WST is the world’s largest area telescope. Dr. Stahl will overview the science goals for the WST and the way they drove the WST structure, e.g. aperture, wavelength vary, and working temperature. Along with a program standing, Dr. Stahl’s presentation supplies an summary of the WST’s main mirror expertise growth and fabrication standing. Take this chance to study extra about one of the thrilling and bold area science missions ever tried.

Dr. H. Philip Stahl is a Senior Optical Physicist on the NASA Marshall Area Flight Heart the place he’s at the moment main a research to mature mirror applied sciences for a brand new giant aperture UV/Optical/IR telescope to interchange Hubble. Beforehand, he was accountable for growing candidate main mirror applied sciences for the WST.
Dr. Stahl is a number one authority in optical metrology, optical engineering, and phase-measuring interferometry. Lots of the world’s largest telescopes have been made with assistance from high-speed and infrared phase-measuring Interferometers developed by him. He’s a Fellow of SPIE and OSA and previous ICO Vice President and was SPIE’s 2014 President. He earned his Ph.D. in Optical Science on the College of Arizona in 1985.
