Scheduled to launch in spring 2019, the Webb telescope will make history as the largest infrared observatory ever sent into space. It takes a large team of creative minds to imagine, build, launch, and operate an innovative space observatory such as Webb.

When Webb begins its scientific exploration of the infrared universe, the knowledge it gleans will be shared around the globe. Astronomers from throughout the world will be able to use Webb, winning time on the telescope by submitting proposals to a group of scientists that evaluates the best use of the telescope's hours. After a period for the astronomers to complete their work, those observations will be made available to the public and scientific community for more study, ensuring that the world gets the most from every iota of data the telescope collects.

Webb is an international collaboration between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). The NASA Goddard Space Flight Center is managing the development effort. The main industrial partner is Northrop Grumman; the Space Telescope Science Institute will operate the Webb telescope after launch.
