How NASA Tracks the Asteroids Flying by Earth

On Wednesday, April 19, an asteroid missed Earth by 1.1 million miles – a distance closer than you might think. This week, Tech Briefs spoke with NASA’s Planetary Defense Officer about the efforts behind tracking this type of flyby.

Creating the Future: Wearable Bands Offer Continuous Blood-Pressure Measurement

The pneumatic cuff, a device traditionally used to measure blood pressure, has had a prominent place in doctors' offices for more than a century. As part of a year-long fellowship at Northwestern University, two clinicians and two engineers teamed up to develop a new way of measuring blood pressure: cuffless, wearable wristbands.

Brooke Thornton, Mission Operations Manager, NASA’s Langley Research Center, Hampton, VA

On February 19, The Stratospheric Aerosol and Gas Experiment (SAGE) III instrument launched aboard a cargo capsule to the International Space Station. SAGE III — equipped with a telescope, grating spectrometer, and charge coupled device detector array — will use the light from the Sun and Moon to provide a profile of the atmosphere, including the Earth’s ozone layer. The technology will launch aboard the Falcon Dragon 9, a rocket developed by the Hawthorne, CA-based SpaceX.

A Novel Orbiting Cloud Imager System for IR/UV/ X-Ray Bands

Applications include telecommunications involving satellite links, agile military communication, reconnaissance, and surveillance of ground assets from orbit.Typically, the cost of a spaceborne imaging system is driven by the size and mass of the primary aperture. Innovative solutions for imagers that are less complex and are lightweight are very desirable. Currently, telescopes such as JWST and ATLAST are very expensive and very complex.
