Update: NASA's Webb 'Strutting its Stuff' in New 'Behind the Webb' Video The newest video in the "Behind the Webb" series, called "Strutting its Stuff," provides a look at three “struts†or poles that fold and unfold the secondary mirror on the James Webb Space Telescope. The video series takes viewers behind the scenes to understand more about the Webb telescope, the world's next-generation space observatory and successor to NASA's Hubble Space Telescope. Designed to be the most powerful space telescope ever built, Webb will observe the most distant objects in the universe, provide images of the first galaxies formed and study unexplored planets around distant stars.

Engineers Conduct "Heart Surgery" on the Webb Telescope In this new NASA video, engineers from Airbus Defense and Space (DS), Ottobrunn, Germany, dressed in white protective suits and special white gloves, recently completed a delicate surgical procedure to exchange two key components from the "heart" of an instrument on the James Webb Space Telescope at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

http://eandt.theiet.org/magazine/2015/04/james-webb-space-telescope.cfm Seems to me that ('cause of the costs), they could put several Hubbles into Space already...& they got several of them just waiting around to be refitted... ;) non-profit org. Play4Life in Zagreb, Croatia, EU |

http://eandt.theiet.org/magazine/2015/04/james-webb-space-telescope.cfm The JWST is much more sophisticated than the Hubble and could even reveal more information on Dark Energy! I'd say this project is money well spent :) rOZZ Music Pictures |

NASA Technology Protects Webb Telescope from Contamination "The Molecular Adsorber Coating (MAC) is a NASA Goddard coatings technology that was developed to adsorb or entrap outgassed molecular contaminants for spaceflight applications," said Nithin Abraham, Thermal Coatings Engineer at NASA's Goddard Space Flight Center in Greenbelt, Maryland. MAC is currently serving as an innovative contamination mitigation tool for Chamber A operations at NASA Johnson Space Center in Houston, Texas. Click link to view photograph. rOZZ Music Pictures |

http://eandt.theiet.org/magazine/2015/04/james-webb-space-telescope.cfm yes, but it's running LATE...& over expences! & US has a several Hubble clones, that r finished...just need a different optics setting, 'cause they were spy satelites! ;) non-profit org. Play4Life in Zagreb, Croatia, EU |

Th Association of Universities for Research in Astronomy has proposed a new High Definition Space Teleacope with a 10 meters mirror, which should work in the optical and UV ranges, not in the IR like JWST. They say that the JWST is not the Hubble successor. The new telescope should not need any cooling equipment,unlike JWST, and should be placed in the L2 Lagrange point. Its cost should be 10 billion USD, compared to the 8 billion USD of the JWST. Its main mission would be that of analyzing the atmospheres of the exoplanets to search for any sign of life. Tullio |

NASA's Webb Sunshield Gives an "Open Wide" for Inspection The sunshield on NASA's James Webb Space Telescope is the largest part of the observatory—five layers of thin, silvery membrane that must unfurl reliably in space. The precision in which the tennis-court sized sunshield has to open must be no more than a few centimeters different from its planned position. Click link to view photograph. NASA's Webb "Cosmic Shutterbug" in New 'Behind the Webb' Video The newest video in the "Behind the Webb" series, called "Cosmic Shutterbug," provides a look at how tiny "microshutters" will open to give NASA's James Webb Space Telescope the capability to see farther in the universe than ever before.

James Webb Space Telescope Backplane Arrives at NASA Goddard for Mirror Assembly One of the most crucial pieces of the James Webb Space Telescope, the flight backplane, arrived on Aug. 25, on schedule for Webb's 2018 launch date at NASA's Goddard Space Flight Center in Greenbelt, Maryland, for mirror assembly. The backplane is the "spine" of the telescope, responsible for holding its 18 hexagonal mirrors and instruments steady while the telescope is looking into deep space.

The JWST will be quite accurate in analyzing the atmosphere of exoplanets: http://www.stsci.edu/jwst/jwst-science-corner/paper-summary-exoplanets/ Why JWST is important:- This study shows that with JWST spectroscopy, it is possible to constrain or detect anthropogenic pollution in the atmospheres of exoplanets. rOZZ Music Pictures |

James Webb Space Telescope's ISIM Passes Severe-Sound Test A critical part of NASA's James Webb Space Telescope successfully completed acoustic testing during the week of Aug. 3. The Integrated Science Instrument Module, or ISIM, passed all of the "severe sound" tests that engineers put it through. rOZZ Music Pictures |

The Secrets of NASA's Webb Telescope’s "Deployable Tower Assembly" The DTA looks like a big black pipe and is made out of graphite-epoxy composite material to ensure stability and strength with extreme changes in temperature like those encountered in space. When fully deployed, the DTA reaches ten feet in length. Click link to view photograph. rOZZ Music Pictures |

NASA's James Webb Space Telescope Structure Stands Tall The flight structure of NASA's James Webb Space Telescope was standing tall on a platform in the cleanroom at NASA's Goddard Space Flight Center in Greenbelt, Maryland on August 30. The telescope structure includes the primary mirror backplane assembly; the main backplane support fixture; and the deployable tower structure that lifts the telescope off of the spacecraft. The three arms at the top come together into a ring where the secondary mirror will reside. http://www.nasa.gov/feature/goddard/nasas-james-webb-space-telescope-structure-stands-tall Video with link. |

Three more years til it is launched. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |
