A Tech Briefs TV video demonstrates NASA’s rotary-wing “air taxi” concept. The vehicles, in theory, have the capacity for vertical take-off and landing, eliminating the need for long runways.

MIT has built the first-ever plane with no moving parts. Instead of turbine blades, propellers, and fans, the aircraft relies on an “ionic wind” — a silent but strong flow of ions, produced onboard, which generates enough thrust to propel the plane over a sustained, steady flight.

Glenn's revolutionary Shape Memory Alloy Rock Splitters (SMARS) device is fabricated from nickel-titanium-halfnium (NiTiHf), nickel-titanium-zirconium compositions, or a combination. These compositions contain a secondary, nanometer-sized precipitate phase that is produced through processes of compositional...

High-precision ranging (optimetric) instruments are highly desired for both space navigation and communications as well as gravitational-based science missions. Traditionally, these measurements are made with instruments solely dedicated to ranging (i.e. Doppler shift of a...

Accumulation of insect strikes on the leading edge of airplane wings is a more serious problem than one might realize. Depending on the magnitude, such accumulation changes the aerodynamic characteristics of the wing, causing a change from...

Richard Duke spoke with Tech Briefs about the nature of the space-junk problem — and how his team plans to fix it.

NASA technologies have led to many of the commercial products and innovative solutions we use every day, from memory foam and freeze-dried foods to exercise equipment and water purifiers. The October issue of Tech Briefs showcased a number of these NASA spinoffs. Read the Tech Briefs feature article, and share...
