Crucial Science Instrument Installed into Webb Structure

A technician is installing the bolts that will hold the MIRI, or Mid-Infrared Instrument, to the composite Integrated Science Instrument Module (ISIM) structure, or the black frame. The MIRI is attached to a balance beam, known as the Horizontal Integration Tool (HIT), hanging from a precision overhead crane. That is the identical tool that Hubble engineers employed to prepare hardware for its servicing missions.

Engineers worked 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. As the successor to NASA’s Hubble Space Telescope, the Webb telescope will be the most strong space telescope ever constructed. It will observe the most distant objects in the universe, offer pictures of the very first galaxies formed and see unexplored planets about distant stars.

Boeing B-17 – Duxford Airshow Oct 2010

Boeing B-17 at Duxford Airshow October 2010.
The Boeing B-17 Flying Fortress was a four-engine heavy bomber aircraft created in the 1930s for the United States Army Air Corps (USAAC). Competing against Douglas and Martin for a contract to develop 200 bombers, the Boeing entry outperformed each competitors and more than met the Air Corps’ expectations. Despite the fact that Boeing lost the contract simply because the prototype crashed, the Air Corps was so impressed with Boeing’s design that they ordered 13 a lot more B-17s for additional evaluation. From its introduction in 1938, the B-17 Flying Fortress evolved by way of quite a few design advances.
The B-17 was mostly employed by the United States Army Air Forces (USAAF) in the daylight precision strategic bombing campaign of Planet War II against German industrial and military targets. The United States Eighth Air Force primarily based at Thorpe Abbotts airfield in England and the Fifteenth Air Force primarily based in Italy complemented the RAF Bomber Command’s night time area bombing in Operation Pointblank to assist safe air superiority over the cities, factories and battlefields of Western Europe in preparation for Operation Overlord. The B-17 also participated to a lesser extent in the War in the Pacific exactly where it carried out raids against Japanese shipping and airfields.
From its pre-war inception, the USAAC (later USAAF) touted the aircraft as a strategic weapon it was a potent, higher-flying, long-variety bomber that was capable to defend itself, and to return house in spite of in depth battle harm. It swiftly took on mythic proportions, and extensively circulated stories and photographs of B-17s surviving battle harm enhanced its iconic status. With a service ceiling higher than any of its Allied contemporaries, the B-17 established itself as an efficient weapons technique, dropping far more bombs than any other U.S. aircraft in World War II. Of the 1.five million metric tons of bombs dropped on Germany by U.S. aircraft, 640,000 tons have been dropped from B-17s.
