The Pegasus XL rocket's aft skirt fins are constructed from a single-piece, solid, foam core and wet-laid carbon composite construction around a central titanium shaft. Its wing panels consist of a carbon-faced foam sandwich. The rocket wing's channel section spars that carry the primary bending loads and half-ribs are also made of carbon.
ATK provided the solar array that will power the NuSTAR satellite itself, as well as powering its onboard sensors for NASA's planned multiyear experiments. The company built the NuSTAR observatory's instrument structure, which includes an integrated focal plane bench and optical bench, both made of high-strength composites.

The focal plane bench serves as a stable, multi-functional platform for NuSTAR's instruments. It also functions as the primary interface to the satellite bus structure. During launch, this bench supports the stowed mast/canister and the optical bench with its integrated X-ray optics. The focal plane assembly's instrument electronics and metrology detectors are also mounted on this bench. These perform instrument alignment, focus, and data collection, which are all mission-critical operations.
The optical bench is a precision-engineered, highly stable structure responsible for supporting the X-ray optics modules, metrology lasers, adjustment mechanism, and star tracker. Held stable within the optical bench, the X-ray optics modules will acquire images as the NuSTAR satellite maps supernova explosions and searches for black holes.
Ann, while the application of composites for the booster is new stuff, their use in the spacecraft itself is old hat. I worked at one spacecraft plant where we made our own composites from raw materials. One of our direct competitors, with whom we were merged later on, got their composites from a company whose main business was railcars. It was an interesting revelation when we found out.
I actually worked on the testing of the UARS satelite structure. It was the first large composite structure. If you recall, UARS recently fell back to earth. It was one of the largest satellites to do so. It was the size of a school bus and filled the Shuttle cargo bay. In testing we found some interesting things out about how the composites reacted structurally. Now, this was in the 1980s. It would have been nice to have some of the more robust CAE tools available today.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
