Data Recorders Prepare Orion for Splashdown Test

Data recorders and software Diversified Technical Systems (DTS) Seal Beach, CA 562-493-0158 www.dtsweb.com It’s no simple task to travel 3,600 miles into space, blaze back through Earth’s atmosphere at 20,000 mph with temperatures approaching 4,000 °F, and then splash-land into the Pacific Ocean. That’s why NASA spent three years dropping the 18,000-pound mockup of the Orion space capsule into a special test pool wired with hundreds of sensors, strain gauges, and accelerometers to measure stresses and structural integrity, as well as the safety of future astronauts onboard.

Researcher Spotlight: Atom­Thick Material Offers 2D Imaging Possibilities

Rice University scientists have developed a two-­dimensional, atom­-thick, light-­sensitive material called CIS, a single­-layer matrix of copper, indium, and selenium atoms. Sidong Lei, a graduate student, also built a prototype — a three-­pixel charge­-coupled device (CCD) sensor — to prove the material’s ability to capture an image. The optoelectronic memory material may be the basis for future flat imaging devices and two­-dimensional electronics.

3D Vision System Aids 560-Mile Piloted Drive

Audi completed a long-distance test drive of its Audi A7 Sportback semi-autonomous concept vehicle, finishing the journey at the International CES 2015 consumer electronics show in Las Vegas. The “piloted driving” — Audi’s take on combining autonomous driving with individual control — began in Stanford, California and ended two days and 560 miles later on January 6, 2015.

Vision Sensors

Baumer (Southington, CT) has expanded its VeriSens XC series vision sensor portfolio to include models capable of color identification and inspection. Color FEX, a new, intelligent feature for setup of 3D color identification and definition, automatically identifies and visualizes object colors in 3D as color spheres. The resulting absence of sphere collisions ensures reliable color inspection.

ORCA Prototype Ready to Observe Ocean

If selected for a NASA flight mission, the Ocean Radiometer for Carbon Assessment (ORCA) instrument will study microscopic phytoplankton, the tiny green plants that float in the upper layer of the ocean and make up the base of the marine food chain.Conceived in 2001 as the next technological step forward in observing ocean color, the ORCA-development team used funding from Goddard’s Internal Research and Development program and NASA’s Instrument Incubator Program (IIP) to develop a prototype. Completed in 2014, ORCA now is a contender as the primary instrument on an upcoming Earth science mission.The ORCA prototype has a scanning telescope designed to sweep across 2,000 kilometers (1,243 miles) of ocean at a time. The technology collects light reflected from the sea surface that then passes through a series of mirrors, optical filters, gratings, and lenses. The components direct the light onto an array of detectors that cover the full range of wavelengths.Instead of observing a handful of discrete bands at specific wavelengths reflected off the ocean, ORCA measures a range of bands, from 350 nanometers to 900 nanometers at five-nanometer resolution. The sensor will see the entire rainbow, including the color gradations of green that fade into blue. In addition to the hyperspectral bands, the instrument has three short-wave infrared bands that measure specific wavelengths between 1200 and 2200 nanometers for atmospheric applications.The NASA researchers will use ORCA to obtain more accurate measurements of chlorophyll concentrations, the size of a phytoplankton bloom, and how much carbon it holds. Detecting chlorophyll in various wavelengths also will allow the team to distinguish between types of phytoplankton. Suspended sediments in coastal regions could also be detected by the instrument.SourceAlso: Learn about a Ultra-Low-Maintenance Portable Ocean Power Station.
