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 […]
