The launch date for the James Web space telescope is still on for Oct 21, 2021.
Bout time
It will be positioned 1 million miles away from earth at L2, Lagrange point #2, in a stable orbit.
Its infrared camera should give us more detail at the outer edges of our solar system, if it all works, pretty exciting stuff.
Servicing missions to L2 will be tough for servicing missions. I hope they've already checked JW for spherical aberrations.
