Dear James Webb Space Telescope,
You're going to change everything. When you finally launch in March 2021 (we hope), you're going to shine a light on where we came from and where we might end up living.
We've waited a long time for you; your original target launch date was all the way back in 2007. But I know all about taking a long time to get ready to go out—and when you finally make your appearance, you're going to be beautiful, with your 25-foot golden mirror and your five-layer sunshield. But you’ll be hard at work, too: You'll hang there in a stable orbit, one million miles away from Earth at the L2 Lagrange point, as you gaze out into space.
