The James Webb Space Telescope is one of the most ambitious and technically complex missions NASA has ever focused on. The construction of an infrared observatory of this size, power and complexity has never been attempted before. To ensure seamless operation in space, the breakthrough technology built into Webb needs to be thoroughly tested before launch.
The entire design of the Webb telescope took years and was designed to see more of the cosmos ever. It required hundreds of scientists, engineers, optics experts, and many others to pool their knowledge in ways never seen before. Supported by the collaboration of three prominent space agencies: NASA, the European Space Agency and the Canadian Space Agency, Webb has welcomed more than 1
"When" We first thought of Webb, it was not technically feasible. We had to invent some things before we could build them – not unlike the Apollo program in this regard, "said Paul Geithner, Deputy Project Manager – Engineering at NASA's Goddard Space Flight Center at Greenbelt, Maryland
Before building the telescope altogether Scientists and engineers began developing ten new technological innovations that the world had never seen, and these advances, known as "fundamental technologies," have been integrated into Webb, paving the way for the development of the most powerful scientific Observatory ever built.
With nearly 100 times the power of its scientific predecessor, the Hubble Space Telescope, Webb is expected to reveal a wealth of information about where we come from, how planets and stars are created, and will also be used to make detailed analyzes of planets both in ours own solar system as well as elsewhere in the cosmos.
A The revolutionary lightweight carbon composite material that can hold its rigid shape on a ten-thousandth of a human hair at temperatures near absolute zero, forms Webb's backplane and science instrument support structures. This new material provides exceptional resilience while experiencing very little thermal expansion and contraction at extreme space temperatures.
Webb's mirror segments began as beryllium ore mined in Utah. They traveled all over the United States to form, easily coat, polish, coat with gold, and finally, with the help of a robotic arm, place it perfectly on the structure of the back wall.
"From a technical point of view, Webb is extraordinary Science means it has to be big, in space, and half of it has to be very cold, which means that we had to design it for use in space travel collapsible, and then unfold remotely, requires us to build the cold optics just the wrong way in gravity and air at room temperature, so it's just right – the right size and shape – if it's weightless in the vacuum of space and at As cold temperatures work, the air turns solid, "said Geithner.
A global team of engineers, engineers and scientists worked together to build and test this revolutionary telescope. In addition to space flight hardware, the Webb mission required the construction of assembly structures to assemble the telescope, the use of test equipment to ensure that each component is ready for the rigors of space flights, transport cases to ship the land for service, technical copies called pathogens, and even a "test bed" telescope.
For Webb and all of its new technologies to function as expected in space, NASA deliberately exposes its spacecraft to extreme temperatures in a massive cryogenic chamber, known simply as Chamber A's located in Houston, Texas. Soil tests to simulate start-induced vibrations or to study structural strength have also proven to be critical to the development of a successful spacecraft.
To ensure that all aspects of structural dynamics are evaluated, including vibration, vibroacoustics, modal properties, sound transmission loss, and shock tests, Webb was bombarded, shaken, frozen, and retested by a long litany of tests.
The James Webb Space Telescope will be the world's leading space research center. Webb will solve puzzles of our solar system, peer into distant worlds around other stars, and explore the mysterious structures and origins of our universe and place in it. Webb is an international project led by NASA with its partners, the European Space Agency (ESA) and the Canadian Space Agency (CSA).

Agreement allows Korean astronomers access to Gemini Observatory
Hilo HI (SPX) July 25, 2018
On Tuesday, an agreement was signed between the Korea Astronomy and Space Science Institute (KASI) and the agencies owning the International Gemini Observatory and operating the Gemini Observatory.
"Having been part of Gemini for the past four years, the Korean astronomical community is pleased to become a full partner in the Twin Gemini telescopes in Hawaii and Chile," said Narae Hwang, director of K-GMT Sci … read More
