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? |

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. Click link to watch the pic. rOZZ Music Pictures |

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.

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.

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! ;) non-profit org. Play4Life in Zagreb, Croatia, EU |

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. the atricles just say it's Hubble size telescopes...not that they ARE Hubble copies... :/ thanks for the links, but don't troll. non-profit org.

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. Click links to view pics. rOZZ Music Pictures |

update. 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. http://www.nasa.gov/content/goddard/amazing-view-of-engineers-preparing-nasas-gigantic-space-simulation-chamber-for-massive-test/index.html#.VJn6nP8DI |
