Spatial Phase Imaging

In 1928, Alexander Fleming, a young Scottish scientist with a side practice of discretely treating the syphilis infections of prominent Londoners, was researching agents that could be used to combat such bacterial infections. He left his practice for a 2-week vacation, inadvertently leaving several bacterial culture plates unwashed and out of the incubator. When he returned, what immediately struck him was that the plates had grown mold, but the bacteria Fleming had been working with was being fended off by the mold, which he called penicillin, after the mold Penicillium notatum. Although unable to refine or purify the penicillin, Fleming had discovered the archetype of modern antibiotics.

Electrical Conductivity in Textiles

Copper is the most widely used electrical conductor. Like most metals, though, it has several drawbacks: it is heavy, expensive, and can break. Fibers that conduct electricity could be the solutions to these problems, and they are of great interest to NASA.

Laser Mapping for Visual Inspection and Measurement

Each space shuttle orbiter has 38 Primary Reaction Control System (PRCS) thrusters to help power and position the vehicle for maneuvers in space, including reentry and establishing Earth orbit. Minor flaws in the ceramic lining of a thruster, such as a chip or crack, can cripple the operations of an orbiter in space and jeopardize a mission. The ability to locate, measure, and monitor tiny features in difficult-to-inspect PRCS thrusters improves their overall safety and lifespan.

Nano Goes Magnetic to Attract Big Business

Glenn Research Center has combined state-of-the-art electrical designs with complex, computer-aided analyses to develop some of today’s most advanced power systems, in space and on Earth. The center’s Power and On-Board Propulsion Technology Division is the brain behind many of these power systems. For space, this division builds technologies that help power the International Space Station, the Hubble Space Telescope, and Earth-orbiting satellites. For Earth, it has woven advanced aerospace power concepts into commercial energy applications that include solar and nuclear power generation, battery and fuel cell energy storage, communications and telecommunications satellites, cryocoolers, hybrid and electric vehicles, and heating and air-conditioning systems.
