It would have been a heroic coda to an already ambitious, historic mission, but alas, it was not meant to be. For the past few months, […]

All Webb Telescope's 18 Primary Gold-Coated Mirrors Now Installed to Unravel Mysteries of the Universe

From NASA: “Inside a massive clean room at NASA’s Goddard Space Flight Center in Greenbelt, Maryland the James Webb Space Telescope team used a robotic am to install the last of the telescope’s 18 mirrors onto the telescope structure.” NASA/Chris Gunn

Construction of the James Webb Space Telescope (JWST), a NASA, European Space Agency […]

Webb Telescope Component Completes Critical Tests as Mirror Installations Continue

Less than three years from its launch, the James Webb Space Telescope (JWST), an international collaboration between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA), continues to take shape. As 2015 rolled into 2016, engineers working on the JWST have been busy testing one of its essential science components. On […]
