telescopes at lagrange point L2: webb, euclid, more?

LOL I expected to have some deep sky image. Yes, the JWST (James Webb Space Telescope) is a nice instrument. I don't know what's the expected life it has. The Hubble Space telescope has been running since 1990!
What's fascinating about the JWST is the alignment (co-phasing?) of the segmented mirrors.
