It had been scheduled to launch in October 2018. No technical performance issues, just taking longer to get it ready than expected.
''The change in launch timing is not indicative of hardware or technical performance concerns,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate at Headquarters in Washington. “Rather, the integration of the various spacecraft elements is taking longer than expected.” ''

I'm excited to see new views and discoveries of our Universe that will be made by the Web Telescope once it's in place stationed about a million miles away from the earth at Lagrange point 2 [L2].

Operating primarily in the infra red light range of the spectrum Webb will be able to see the first galaxies that were formed.

Let's hope that the rocket that launches the Web telescope doesn't suffer a catastrophic failure in flight.

Dang it all. Once again, the launch date of the Web telescope has had to be pushed back. This time to 2021. Tests created small tears in the thin fabric of the James Webb Space Telescope’s sunshield.
''Yet again, NASA is delaying the launch of its flagship astrophysics mission, the James Webb Space Telescope (JWST), to 30 March 2021—the third schedule slip in less than a year. An independent review of the project concluded that there was excessive optimism in the launch schedule and suggested the delay, one of 32 recommendations to improve the project’s chances of success. NASA also revealed that the development cost of the telescope would rise from $8 billion to $8.8 billion, requiring it to be reauthorized by Congress, which set an $8 billion cap in 2011. (The total cost of JWST, including operations, is expected to be $9.66 billion.)''

These delays are frustrating. The Web telescope has the potential to make dramatic new discoveries about the Universe. But since it will be parked at L2 about a million miles from earth, it's absolutely essential that everything works once it's in place since it will be beyond the reach of 'repair men.'

Frustrating but not surprising. All government projects work like that whether it's a fighter jet or space telescope. The public is promised a low cost and a reasonable completion date which will inevitably balloon way past the original estimate.

Part of this is politics (if you state how long it really could take no official would approve it) and part of this is due to breaking new ground.

What a boon doggle. Well at least adaptive optics systems are now starting to outperform Hubble, so we only really need space telescopes for bands like IR, X-ray, and some radio.

The Magellan Telescope is soon to begin construction in Chile and if things stay on schedule it will be completed by 2024. It will have 10 times the resolving power of the Hubble space telescope.

Excavation has begun at the site where the Magellan Mega-scope is to be built.
Excavation begins on Giant Magellan Telescope site in Chile
Pasadena, Calif. – August 14, 2018 – GMTO Corporation (GMTO) today announced the start of hard rock excavation for the Giant Magellan Telescope’s massive concrete pier and the foundations for the telescope’s enclosure on its site at Las Campanas Observatory in Chile. The work will be performed by Minería y Montajes Conpax (known as Conpax),

I still hope the James Webb telescope finally gets launched successfully.
