Machining the James Webb Space Telescope Mirrors

What is the shape of the universe?
How did it build up its present elemental and chemical composition?
How do galaxies form and evolve?
How do stars and planetary systems interact?

All these mysteries and more will be answered by NASA's remarkable James Webb Space Telescope that will look deeper into space — and farther back in time — than ever before. The machining contractor that made the ultra precise mirror segments chose Mitsui Seiki to supply the machine technology.
