Webb Enters Giant Test Chamber for 3 Month Final Deep-Freeze Before Launch Next Year

NASA’s James Webb Space Telescope sits in front of the door to Chamber A, a giant thermal vacuum chamber located at NASA’s Johnson Space Center. The telescope was moved into the chamber on June 20, where it will spend the summer undergoing 93 days of tests at sub-freezing cryogenic temperatures. The telescope will operate […]

The Next Big Thing: NASA Officially Gives the Go-Ahead for WFIRST Telescope—An Interview With Dr. Neil Gehrels

An artist’s concept of the Wide Field Infrared Survey Telescope (WFIRST). NASA has officially chosen the infrared-space telescope as the scientific successor to the James Webb Space Telescope, with a projected launch date around the 2024 timeframe. WFIRST is expected to make significant contributions in the study of dark energy and the characterisation of […]
