Webb Space Telescope
James Webb Space Telescope Mission to Our Solar System

Goals: The international James Webb Space Telescope (JWST) is designed to study every phase in the history of our universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own solar system. Its instruments will be designed to work primarily in the infrared range of the electromagnetic spectrum, with some capability in the visible range.

Accomplishments: This mission is in development.
