Hello!

We are scientists and engineers working at NASA Goddard, and leading the current testing on the James Webb Space Telescope in NASA Johnson’s historic Chamber A. Why is this testing notable? Chamber A is a giant thermal vacuum chamber, and our telescope is undergoing a ~100 day, end-to-end test at extremely cold temperatures, in a space-like vacuum inside of it. We’ll answer questions about why Webb has to perform in extreme cold, why NASA built a giant, infrared telescope, and what cryogenic testing is all about.

We’ll be online for an hour or so on Thursday October 19th, at 1pm ET for questions, and we will be checking back in periodically after the Q&A for other questions.

NASA’s James Webb Space Telescope (Webb) is the world’s premier space telescope of the next decade. It will delve deeper into our solar system, look beyond to distant worlds around other stars, and help us to learn more about the universe and our place in it. Webb is an international collaboration among NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA).
