The Webb telescope or any infrared telescope; can they recast their images so they will appear as regular visible wavelength images? I imagine that they couldn't completely do that. Some images would just be missing too much info but would it be close?

It is normal to re-map an IR (or indeed any other non-visible EM radiation) image into the visible part of the spectrum - it is easier for us humans to see what is going on when looking at a picture than looking at the data as a load of numbers...

Will they be the beautiful pictures that we see from Hubble?

Will they be the beautiful pictures that we see from Hubble?

Even better is my guess:) The JWST is much more sophisticated than the Hubble.

Many of the most spectacular pictures from Hubble are composites of false-colour IR plus visible, or enhanced colour visible so there is no reason not to expect the same technologies to be applied, but given the greater resolution of the JWT with even greater visual effect.

James Webb Space Telescope Sunshield Test Unfolds Seamlessly

The sunshield separates the observatory into a warm, sun-facing side (reaching temperatures close to 400 degrees Farenheit), and a cold side (185 degrees below zero) where the sunlight is blocked from interfering with the sensitive telescope instruments. It provides the instruments with an effective sun protection factor, or SPF, of one million.
The sunshield’s membrane layers, each as thin as a human hair, are made of Kapton, a tough, high-performance plastic coated with a reflective metal. On orbit, the observatory will be pointed so that the sun, Earth and moon are always on one side, with the sunshield acting as an umbrella to shade the telescope mirrors and instruments from the warmer spacecraft electronics and the sun.

James Webb Space Telescope's Heart Survives Deep Freeze Test

Part II

After 116 days of being subjected to extremely frigid temperatures like that in space, the heart of the James Webb Space Telescope, the Integrated Science Instrument Module (ISIM) and its sensitive instruments, emerged unscathed from the thermal vacuum chamber at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
The Webb telescope's images will reveal the first galaxies forming 13.5 billion years ago. The telescope will also pierce through interstellar dust clouds to capture stars and planets forming in our own galaxy. At the telescope's final destination in space, one million miles away from Earth, it will operate at incredibly cold temperatures of -387 degrees Fahrenheit, or 40 degrees Kelvin. This is 260 degrees Fahrenheit colder than any place on the Earth’s surface has ever been. To create temperatures that cold on Earth, the team uses the massive thermal vacuum chamber at Goddard called the Space Environment Simulator, or SES, that duplicates the vacuum and extreme temperatures of space. This 40-foot-tall, 27-foot-diameter cylindrical chamber eliminates the tiniest trace of air with vacuum pumps and uses liquid nitrogen and even colder liquid helium to drop the temperature simulating the space environment.

Webb Telescope Mirrors: Stepping Stones to the Cosmos

Scientists and engineers placed two NASA James Webb Space Telescope test primary mirror segments onto the support structure that will hold them, where they resemble stepping stones, as seen in this photo.
There are four types of mirrors that will fly aboard NASA's James Webb Space Telescope: The primary, secondary, tertiary and fine steering mirrors.
Together they will direct light into sensitive instruments, like stepping stones towards new discoveries about the cosmos.
Highly trained engineers and technicians from NASA, Exelis, and Northrop Grumman lifted the two test primary mirror segments in the photograph onto the support structure, working in a giant clean room at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
Both mirrors are made from beryllium. These primary mirror "test" segments are also flight spares. One of the mirrors is coated with a microscopically fine film of gold just like the actual flight mirrors, while the other is not. For the testing these mirrors will undergo, it is not critical that they all be gold-coated. The gold coating will enable the mirrors to most efficiently reflect the infrared light from distant galaxies.

NASA's Webb Telescope Pathfinder Telescope Fully Assembled

Inside a giant clean room at NASA's Goddard Space Flight Center in Greenbelt, Maryland, the pathfinder telescope, a practice section of the James Webb Space Telescope, stands fully assembled. Teams of engineers built and aligned the pathfinder telescope to rehearse assembly and testing before the actual telescope is built. After the team installs the test sensors and completes their final close out, the pathfinder telescope will be shipped to NASA's Johnson Space Center in Houston, Texas for cryo-optical testing.

All three? OK.

U mean ALL 5 of lagrange points...YES!

And only 2 are stable enough, so those 2 are able to have JWST in it! ;)

There are THREE Hubbles, and they are still up there, and operational. Two of them were pointing down instead of up, and NRO handed them off to NASA two years ago after admitting they exist.

Documentation? If true I missed that one.

The last link at The Planetary Society, surmizes that these are actually two more that were part of the Keyhole program, which currently has 15 birds in orbit, probably of this type.

Oh, and I guess my wetware had a glitch. These two have never been launched. Still in cold storage.

I'm sure you can find more links.

the atricles just say it's Hubble size telescopes...not that they ARE Hubble copies... :/

thanks for the links, but don't troll.

NASA's Webb Telescope ISIM Gets Cubed for Gravity Test

The James Webb Space Telescope's ISIM structure recently endured a "gravity sag test" as it was rotated in what looked like giant cube in a NASA clean room.
The Integrated Science Instrument Module (ISIM) that will fly on the Webb telescope was rotated upside down inside a cube-like structure in the cleanroom at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The purpose of "cubing" the ISIM was to test it for "gravity sag," which is to see how much the structure changes under its own weight due to gravity.

Amazing View of Engineers Preparing NASA's Gigantic Space Simulation Chamber for Massive Test

"This is what space science is all about," said NASA photographer Chris Gunn, who captured a photo from outside the enormous mouth of NASA's giant thermal vacuum chamber called Chamber A at Johnson Space Center in Houston. Previously used for manned spaceflight missions, this historic chamber is now filled with engineers and technicians preparing for one of NASA's biggest missions, the James Webb Space Telescope.

Space Simulation Chamber Prepared for Testing Webb Telescope

This photo was captured from outside the enormous mouth of NASA's giant thermal vacuum chamber, called Chamber A, at Johnson Space Center in Houston.
