NASA : James Webb Space Telescope's Golden Mirror .- Espejo de oro del telescopio espacial James Webb

Hola amigos: A VUELO DE UN QUINDE EL BLOG., hemos recibido información de la Agencia Espacial NASA, el espejo del Telescopio James Weber, nos dice: "los espejos del telescopio están cubiertos por una capa de espesor microscópico de oro, que los optimiza para reflejar la luz infrarroja, que es la longitud de onda de la luz principal de este telescopio observará. Para garantizar el espejo es a la vez fuerte y ligero, el equipo hizo los espejos de berilio. Cada segmento de espejo es aproximadamente del tamaño de una mesa de café y pesa aproximadamente 20 kilogramos (46 libras). Una película muy fina de capas de oro vaporizados cada segmento para mejorar el reflejo del espejo de la luz infrarroja. El espejo totalmente montado es más grande que cualquier cohete, por lo que los dos lados de la misma se pliegan. Detrás de cada espejo son varios motores para que el equipo puede enfocar el telescopio en el espacio........."

Overhead view of Webb Telescope with hexagonal gold mirrors uncovered
Inside the clean room at NASA's Goddard Space Flight Center, the golden James Webb Space Telescope is viewed from overhead with its secondary mirror booms stowed. This is the position the secondary mirror will be in during launch. In the next few months, engineers will install other key elements, and take additional measurements to ensure the telescope is ready for space.
 
The telescope's mirrors are covered in a microscopically thin layer of gold, which optimizes them for reflecting infrared light, which is the primary wavelength of light this telescope will observe. To ensure the mirror is both strong and light, the team made the mirrors out of beryllium. Each mirror segment is about the size of a coffee table and weighs approximately 20 kilograms (46 pounds). A very fine film of vaporized gold coats each segment to improve the mirror's reflection of infrared light. The fully assembled mirror is larger than any rocket, so the two sides of it fold up. Behind each mirror are several motors so that the team can focus the telescope out in space.
 
The James Webb Space Telescope is the scientific successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built. Webb will study many phases in the history of our universe, including the formation of solar systems capable of supporting life on planets similar to Earth, as well as the evolution of our own solar system. It’s targeted to launch from French Guiana aboard an Ariane 5 rocket in 2018. Webb is an international project led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.
