CubeSat-Compatible, High-Resolution, Thermal Infrared Imager

This imager will consolidate many of the best features in a single technology. Goddard Space Flight Center, Greenbelt, Maryland A small, adaptable, and stable thermal imaging system was developed that can be flown on an aircraft, deployed on the International Space Station as an attached payload, launched on a ride-share as an entirely self-contained 3U CubeSat, flown on a small satellite, or be a co-manifested satellite instrument. When the instrument design is proven, multiple copies of it could be assembled and aligned into an instrument array to enable large-swath thermal imaging from space, all to provide more detailed spatial and temporal data for biomass burning and land surface temperature studies than has heretofore been available from orbit. The instrument has an Earth-observing expected noise equivalent differential temperature (NEDT)

Fiber-Optic Sensor for Aircraft and Structure Lightning Measurement

Langley Research Center, Hampton, Virginia An optical-fiber sensor based on Faraday Effect was developed for measuring total lightning current. Designed for aircraft installation, it is lightweight, non-conducting, structure conforming, and is immune to electromagnetic interference, hysteresis, and saturation. It can also be used on windmills, lightning towers, and can help validate lightning detection network measurements.

New Method Makes Ultrasensitive Conductivity Measurements

Researchers at Rice University have discovered a new way to make ultrasensitive conductivity measurements at optical frequencies on high-speed nanoscale electronic components. The researchers linked pairs of puck-shaped metal nanodisks with metallic nanowires and showed how the flow of current at optical frequencies through the nanowires produced “charge transfer plasmons” with unique optical signatures.

Driving Simulator Tests Artificial Lens for Cataract Patients

An advanced driving simulator will be used to test a patient’s driving ability after cataract surgery. The trial will help determine if a newly developed artificial lens will be approved for sale in the United States. The lens replaces the patient’s natural, cataract-ravaged lens during surgery, and the trial will determine if it sufficiently reduces visual distractions caused by headlights when driving at night.

NASA Tests Asteroid Sampling Instrument

The first of five instruments for a spacecraft that will collect a sample from an asteroid and bring it back to Earth has arrived at Lockheed Martin for installation onto NASA’s Origins Spectral Interpretation Resource Identification Security-Regolith Explorer (OSIRIS-REx). The Thermal Emission Spectrometer (OTES) will conduct surveys to map mineral and chemical abundances and to take the asteroid Bennu’s temperature.
