James Webb Space Telescope

Click image to EnlargeSince 2006, Dynavac has participated in NASA’s James Webb Space Telescope (JWST) Program. JWST is a large infrared telescope with a 6.5m primary mirror. It will be used to find the first galaxies that formed in the early Universe, connecting the Big Bang to our own Milky Way Galaxy. Launch is planned for 2014. For additional information, go to www.jwst.nasa.gov.

Thermal vacuum testing of all subsystems and the completely assembled telescope is being performed in existing vacuum chambers at NASA and at several partnering aerospace companies. Dynavac has upgraded the majority of these chambers with new cryogenic shrouds to simulate the extreme environmental conditions of outerspace. Shrouds have been made for helium (20K) and liquid nitrogen operation (-190°C) and have been installed in chambers ranging in size from 4’ diameter up to 65’ diameter by 120’ tall.

JWST participants looked to Dynavac for its design and fabrication excellence as well its expertise in thermal/cryogenic engineering. We are very proud of our accomplishments and look forward to contributing to the success of this exciting program.
