Produced video showing engineers placing the Webb Telescope's Integrated Science Instrument Module (ISIM) with all four Webb telescope instruments into the Space Environment Simulator for its last cryogenic test before being integraed into the telescope. The microshutters are arranged in a waffle-like grid that contains more than 62000 shutters with each cell measuring 100 µm x 200 µm. The full-scale model of the James Webb Space Telescope is constructed for the 2010 World Science Festival in Battery Park, NY. Engineers from NASA and Northrop Grumman have successfully integrated the James Webb Space Telescope's optical telescope element and spacecraft element together at Northrop Grumman in Redondo Beach, CA. Others helped provide equipment, personnel, and supplies for testing the telescope and its various parts. MIRI's camera will provide wide-field, broadband imaging that will return breathtaking astrophotography. Il y a quelques jours, la Nasa a communiqué sur les premières cibles du James-Webb. The James Webb Space Telescope was named after the NASA Administrator who crafted Apollo program, and who was a staunch supporter of space science. Installation of the mirrors on the backplane requires precision, so practice is important. sera situé à 1,5 million de kilomètres de la Terre ; pourra observer jusqu'à 300 millions d'années après le Big Bang ; aura une durée de vie d’au moins dix ans ; fonctionnera dans un environnement très froid, d'environ -253 °C. La reprise des essais mécaniques est prévue pour le début de l'année 2017. Engineers are working with the Backplane Pathfinder to test and perfect the processes and workflow they will use on the real thing. WFIRST's infrared surveys will create enormous cosmic panoramas. L'heure est aux dernières vérifications. The best way to see back to the early time of the Universe is to observe in the infrared wavelength of light. This rotation simulated the thermal roll used to evenly disperse heat on the Apollo spacecraft during their journeys to and from the Moon. After a flight to Ellington Field in Houston, Texas, Webb was driven to Johnson. Le télescope spatial James-Webb, qui fera mieux que Hubble, testé à -253 °C. Pour s'assurer qu'il fonctionnera correctement dans l'espace, il a d'abord été testé sur Terre, au Centre spatial de la Nasa, à Houston (Texas, États-Unis), à -253 °C. Time-lapse footage of engineers moving the James Webb Space Telescope out of Chamber A after undergoing cryogenic testing at NASA's Johnson Space Center in Houston Texas. The Webb telescope uses many mirrors to direct incoming light into the telescope's instruments. The secondary mirror is called the secondary mirror because it is the second surface the light from the cosmos hits on its route into the telescope. Time lapse sequence of engineers as they work to meticulously to implant the James Webb Space Telescope's Mid-Infrared Instrument into the ISIM, or Integrated Science Instrument Module, in the cleanroom at NASA's Goddard Space Flight Center in Greenbelt, Md. Astronomers have used computers to search this haystack of data for planet-forming environments and narrowed the field to about a half-million sources that shine brightly in the infrared, indicating they may be "needles": dust-rich circumstellar disks that are absorbing their star's light and reradiating it as heat. Animation of the Webb Telescope showing hot, sun-facing side and transitioning to the super cold, shadow side. Le télescope spatial James-Webb (James Webb Space Telescope ou JWST, anciennement appelé Next Generation Space Telescope ou NGST) est un télescope spatial développé par la NASA avec le concours de l'Agence spatiale européenne (ESA) et de l'Agence spatiale canadienne (ASC). », nous explique Pierre-Olivier Lagage, astrophysicien au CEA (Commissariat à l'énergie atomique et aux énergies alternatives) impliqué dans l'imageur Mirim, de la caméra infrarouge Miri, un des quatre instruments de l'observatoire spatial James-Webb. Engineers will control the temperatures of the different parts of the observatory as it cools so outgassed molecules from one part do not deposit elsewhere, such as on sensitive surfaces like the optics, but instead escape to space. The James Webb Space Telescope, the scientific complement to NASA's Hubble Space Telescope, will be the premier space observatory of the next decade. The Webb Space Telescope will study planetary bodies with our solar system and planets orbiting other stars to help scientists better understand how planets form and how they evolve. Otis sera ensuite transféré au centre Johnson de la Nasa à Houston où auront lieu les derniers essais sous vide aux températures cryogéniques, pour tester la performance optique conjuguée du télescope et de ses quatre instruments. Spectroscopy and spectrometry (the sciences of interpreting these lines) are among the sharpest tools in the shed for exploring the cosmos. Cela dit, observer Mars ne sera pas simple. It has a wavelength range of 0.8 to 5.0 microns, and is a specialized instrument with three main modes, each of which addresses a separate wavelength range. There the container is moved into the cleanroom and opened in preparation for the removal of the telescope structure. Assorted views of the Webb Space Telescope as if it's in a studio environment. Webb Spacecraft 2-Segment Animation with Instrument view, Webb Spacecraft 3 Segment Animation with Instrument view (with alpha), Animations of James Webb Space Telescope Mid-Infrared Instrument (MIRI). The other type of habitat is called a debris disk. The MIRI instrument arrived at NASA Goddard Space Flight Center May 30, 2013. The simulation begins about 20 million years after the Big Bang - about 13.7 billion years ago - and extends until the present day. This collection of James Webb Space Telescope videos and imagery is designed to be shown at conventions, conferences, in booths and at public events. Webb's backplane is the large structure which holds and supports the big hexagonal mirrors of the telescope. Animation of the James Webb Space Telescope mirror alignment and phasing process. A video snap shot of Webb's primary mirror segment testing at the Marshall Space Flight Center. A new Microshutter Array for the Webb Telescope's Near Infrared Spectrometer (NIRSpec) is packed and transported by hand one building away at NASA Goddard Space Flight Center to undergo thermal cycling testing and checkouts at it operational temperature of 35 kelvin or -397 Fahrenheit. The James Webb Space Telescope will not be in orbit around the Earth, like the Hubble Space Telescope is - it will actually orbit the Sun, 1.5 million kilometers (1 million miles) away from the Earth at what is called the second Lagrange point or L2. Since the planet is reflecting some of the star's light toward us, there should be changes in the star’s apparent output based on the location of the planet. For expanded B-roll of this process see: 360 B-Roll footage of the James Webb Space Telescope inside NASA's Johnson Space Center in Houston, Texas. Simulating the zero-gravity environment Webb will operate in, engineers employed an innovative series of pulleys, counterbalances and a special crane called a gravity-negation system that perfectly offloaded all of the effects of Earth’s gravity on the observatory. Quant au surcoût engendré, il se chiffre à quelques milliers de dollars, sans trop de conséquences sur un budget total qui a déjà littéralement explosé, passant de quelque 4 milliards de dollars en 2005 à près de 9 milliards de dollars aujourd'hui. The sole secondary mirror that will fly aboard NASA's James Webb Space Telescope was deployed at NASA's Goddard Space Flight Center in Greenbelt, Maryland, on March 24, 2016. Batteries : l’électrode la plus rapide au monde est française ! Bien qu'il soit conçu pour observer des objets distants de plusieurs milliards de kilomètres, observer Mars, à seulement quelques millions de kilomètres, nécessitera de faire très attention à la luminosité de la planète qui pourrait brûler ses instruments. As a result of this collective group effort, scientist will be able to use the world's most advance telescope to break new grounds in science, and both discover and observe new parts of space that have never been seen before. By collecting this information, astronomers will be able to assess which sources should be explored in greater detail. “We definitely did not design the telescope with this target in mind, considering that we started work 21 years ago. The James Webb Space Telescope will be the largest telescope ever sent into space. This b-roll of MIRI was captured in Europe. James-Webb sera aussi utilisé pour estimer les quantités d'eau perdues tout au long de l'histoire de Mars. The engineers will use varying types of light and conditions to inspect Webb. Time-lapse footage of engineers stowing the -J2 wing of the James Webb Space Telescope at Northrop Grumman in Redondo Beach, CA. Article de Rémy Decourt, paru le 05/12/2015. The James Webb Telescope Mission overview. Le lancement du satellite est prévu en octobre 2018 et les premières observations xis mois plus tard. La Nasa a dû, le 3 décembre, suspendre ces essais le temps de comprendre les causes des écarts constatés. The James Webb Space Telescope (sometimes called JWST) is a large, infrared-optimized space telescope.
