On Christmas Day 2021, the Webb Space Telescope (WST) was launched from Arianespace's ELA-3 launch complex at Europe's Spaceport located near Kourou, French Guiana, on an Ariane 5 rocket. This was the beginning of its 29-day, million mile journey out to the second Lagrange point (L2). From L2 the WST will begin its 10-year mission to 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, including formation of galaxies and protoplanetary systems.
With a 6.5-meter diameter mirror, the WST is the world’s largest space telescope. Dr. Stahl will review the science objectives for the WST and how they drove the WST architecture, e.g. aperture, wavelength range, and operating temperature. In addition to a program status, Dr. Stahl’s presentation provides an overview of the WST’s primary mirror technology development and fabrication status. Take this opportunity to learn more about one of the most exciting and ambitious space science missions ever attempted.
