The WEB space telescope hopefully will continue to open the understanding and beauty of the universe.

I can't wait to know the new species in our/other dimension.

Did you know there's a telescoping piece of hardware that interfaces and supports the #JWST spacecraft and telescope?

JWST is made up of four major components — the telescope, the integrated science instrument module, the sunshield and the spacecraft. The Deployable Tower Assembly (DTA) interfaces and supports the spacecraft and the telescope structures, and serves two key functions on Webb.

 First, in the stowed configuration, the DTA allows the telescope and instruments to fit into the rocket fairing with an acceptable center of gravity for launch. Second, in the deployed configuration, it will lift the telescope mirrors and instruments away from the heat of the main spacecraft. This allows the sunshield to unfurl, reducing the amount of radiant heat the instruments are exposed to on orbit," said Ken Aiello, Astro Aerospace cost account manager for Webb and program manager of the DTA.

#JWST will help answer our questions about galaxies - like what gives them their shapes? This image is Ring Galaxy AM 0644-741 as seen by the Hubble Space Telescope. Read more about it: http://apod.nasa.gov/apod/ap150419.html

Inside NASA's giant thermal vacuum chamber, called Chamber A, at NASA's Johnson Space Center in Houston, the James Webb Space Telescope's Pathfinder backplane test model, is being prepared for its cryogenic test. Previously used for manned spaceflight missions, this historic chamber is now filled with engineers and technicians preparing for a crucial test.

Exelis developed and installed the optical test equipment in the chamber.

"The optical test equipment was developed and installed in the chamber by Exelis," said Thomas Scorse, Exelis JWST Program Manager. "The Pathfinder telescope gives us our first opportunity for an end-to-end checkout of our equipment."

"This will be the first time on the program that we will be aligning two primary mirror segments together," said Lee Feinberg, NASA Optical Telescope Element Manager. "In the past, we have always tested one mirror at a time but this time we will use a single test system and align both mirrors to it as though they are a single monolithic mirror."

#JWST will be looking at how galaxies evolve over time, as well as helping us to understand what the first galaxies that formed were like.  This artist's view shows the night sky from a hypothetical planet within a young Milky Way-like galaxy 10 billion years ago, the sky are ablaze with star birth. Pink clouds of gas harbor newborn stars, and bluish-white, young star clusters litter the landscape.

This photo, taken from the inside of Chamber A, a giant cryogenic vacuum chamber at NASA's Johnson Space Center in Houston, shows the large vehicle resembling a bed frame in the foreground that will move James Webb Space Telescope's Pathfinder backplane inside the chamber. The large rounded object on the right side of the photo is the "bed chamber's" giant door.

The actual pathfinder backplane with three support arms forming a triangle is located at the far wall of the clean room where this photo was taken.

Engineers from NASA and Exelis, Rochester, New York, later rolled the pathfinder onto the "bed" and into the chamber where it will undergo a series of optical and thermal tests.

All about the next generation James Webb Space Telescope!
Introduction

The James Webb Space Telescope is the successor to Hubble. It is an infrared telescope with a 6.5m mirror and a sunshade the size of a regulation tennis court! It will launch in 2018.
