After decades of development by a globe-spanning team, JWST is now providing an unprecedented view of the cosmos. Please join us on Thursday, April 13 at 8pm to hear Dr. Marshall Perrin, JWST deputy telescope scientist, talk about the JWST team's experience preparing and operating this new great observatory: from a brief recap of mission design history and development, to prelaunch preparations, to launch and commissioning, and now into the first of many years of science operations at the Earth-Sun L2 point. He will provide a first-hand look at the processes and teamwork we used to deploy the observatory and align its segmented mirror system, and discuss some of the surprises (both challenges and good news) encountered during commissioning. Even from early in telescope commissioning, this observatory's tremendous power and sensitivity were already apparent with spectacular images and spectra, a taste of the tremendous discovery space now being pursued.
