James Webb Space Telescope Marks Successful Completion

Quote:

A preliminary design review has concluded and verified the integrated performance of all subsystems in the Optical Telescope Element on NASA’s James Webb Space Telescope.

The Optical Telescope Element or OTE is the "eye" of the Webb Observatory. The telescope consists of a 6.5-meter (21.3 foot) primary mirror; secondary, tertiary and fine steering mirrors; and supporting structures, deployable tower and control electronics.

Provided it doesn't get stuck when it tries to deploy, as Galileo's dish did.

I'm excited! I just completed my first design for the JWST. It's not much -- an internal telemetry board in the power control unit -- but it's 'something'.

Next up, will be another type of telemetry board, then a heater control board.

NASA's Webb Telescope sunshield preliminary design review complete

Quote:

The tennis court-sized sunshield built by Northrop Grumman for NASA’s James Webb Space Telescope has completed its preliminary design review at the company’s Space Technology facility.

The Webb Telescope is the next-generation space observatory, designed to explore phenomena from distant galaxies to nearby planets and stars. From the origins of the universe to the formation of star systems capable of supporting life on planets such as Earth, the Webb telescope will give scientists unprecedented access to unexplored regions of space.

"The sunshield is absolutely critical to the Webb telescope mission" says Keith Parrish, JWST Sunshield Manager at NASA’s Goddard Space Flight Center, Greenbelt, Md. "It will be folded up around the telescope when the telescope is aboard its rocket during launch. The sunshield will then deploy in space to shade the sensitive, precision telescope optics and science instruments from the Sun and enable the observatory to reach its proper operating temperature and environment. Without it, the telescope and instruments can’t work. Northrop Grumman is leveraging their experience in large deployable structures in space to come up with a design that will do the job for the Webb telescope."

I found this diagram of the satellite bus internal modules.

So, I annotated it with the stuff I am designing.

I thought another branch of my company was building the Reaction Wheels, but it turns out they aren't, after-all.

James Webb Space Telescope's Actual "Spine" Now Being Built

Quote:

Scientists and engineers who have been working on the James Webb Space Telescope mission for years are getting very excited, because some of the actual pieces that will fly aboard the Webb telescope are now being built. One of the pieces, called the Backplane, is like a "spine" to the telescope. The Backplane is now being assembled by Alliant Techsystems at its Magna, Utah facility.

JWST Starting to Take Shape at Goddard Center

Quote:

The James Webb Space Telescope (JWST) is one of the most ambitious observatories ever planned. Designed to work in infrared wavelengths, it will be a partial successor to the famous Hubble Space Telescope. The JWST, which will be able to see the most distant objects in the Universe with the utmost precision, took another step forward recently, when the Integrated Science Instrument Module (ISIM) structure, the backbone of the telescope, arrived at the Spacecraft Systems Development and Integration Facility, at the NASA Goddard Space Flight Center, in Greenbelt, Maryland.

JWST is taking over! The ISIM is sitting in Goddard's big clean room, which used to be almost exclusively for Hubble from the day it went operational until just recently.

Eye Of JWST Marks Major Milestone As Mission Moves Forward

Quote:

The telescope element of NASA's James Webb Space Telescope (JWST), built by Northrop Grumman Corporation (NYSE:NOC - News), has successfully passed a critical design review verifying it will perform as designed, and now moves forward to final manufacturing steps and integration of all subsystems.

The Optical Telescope Element (OTE), which is the eye of the Observatory, includes a giant, 6.5-meter diameter (21.3 ft.) mirror, associated mirrors and support structures.

"Completion of this review is very significant because it provides validation that the telescope element design of the Observatory meets all performance requirements," said Scott Willoughby, JWST Program Manager for Northrop Grumman Aerospace Systems sector.

Waiting for 2014 is like waiting for chrismas! Now that's a launch we'd like to see!!
