When Stars Collide: LIGO Detects Gravitational Waves from ‘Kilonova’ Light Show

In the galaxy NGC 4993, located approximately 130 million light-years from Earth, two neutron stars collided. And, for the first time, scientists detected the gravitational waves to prove it. They may have even solved the long-standing mystery about the origin of gold and platinum.

In 10 years, will brain-controlled UAVs support critical applications?

In this week’s INSIDER story, researcher Panagiotis Artemiadis predicted that we will see an increase in brain-controlled UAVs within the next ten years. The mind-controlled drones, according to the Arizona State University professor, will play critical application roles as noninvasive sensors become cheaper and more robust. Do you agree?

3D Printing’s Impact on the Value Chain

Over the past several decades, 3D printing has expanded into markets in unique ways as innovators have embraced the technology. It wasn’t until the last few years, however, that its potential has been more broadly realized. During this awakening, there has been a rise in claims that the technology will disrupt traditional value chains. However, most businesses who utilize 3D printing have not yet witnessed changes due to a slow moving shift in corporate leaders’ understanding of the technology’s business value.

Airborne Sense-and-Avoid Radar Panel

This lightweight, low-cost antenna could be used on unmanned vehicles in security and disaster response efforts, communications, aerial mapping, and aerial surveillance.

Although unmanned aerial systems (UAS) have proven increasingly useful in a variety of applications, their widespread usage within the National Airspace System is limited because of regulatory restrictions on their access to shared airspace.

Aircraft Engine Exhaust Nozzle System for Jet Noise Reduction

This technology decreases noise in aircraft that have engines mounted above the wing, tail, or fuselage.

A system of nozzles and pylons that redistributes jet exhaust noise sources upstream to reduce jet noise has been developed. Certain aircraft configurations install the propulsion engines above the wing or tail surfaces, or above the fuselage, or in some cases above the structure that is a blend of the wing and body or hybrid wing body aircraft. In these aircraft configurations, reducing noise propagation to the community below is possible by using the aircraft as an acoustic shield for the sources associated with the engine. The more difficult engine noises to be shielded are from the jet exhaust because they are typically distributed downstream, the equivalent of several engine nozzle diameters. This innovation redistributes jet exhaust upstream to reduce noise.

Multi-Fidelity Simulator (MFS)

Many next-generation air traffic algorithms may be formed by learning algorithms or dynamic programming techniques. These techniques form their solutions through iterative methods where the efficacy of a proposed solution needs to be evaluated for every round of iteration. In complex air traffic scenarios, often the only way to evaluate a proposed solution is to simulate the impact of the solution in an air traffic simulator. Such a simulator has to be fast enough to allow for many rounds of iteration. In addition, the simulator will have to be modular enough to allow modules to be created that simulate a portion of the airspace in detail.

Using Aerial Towing to Study Sonic Booms

Researchers are examining a low-cost approach to testing new designs that can enable supersonic travel without creating the nuisance or damage of shock waves.

Researchers at NASA's Armstrong Flight Research Center (AFRC) recently completed a study of the feasibility of aerial towing an unpiloted, sub-scale vehicle to supersonic flight conditions to examine the sonic boom that is produced — or, preferably, not produced.

Origami Techniques Expand Compacted Spacecraft

Origami has once again inspired engineers at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California. Besides aesthetic beauty, the Japanese tradition of paper-folding addresses a persistent problem faced by JPL engineers: how do you pack the greatest amount of spacecraft into the smallest volume possible?

From the Earth to the Moon: How Robert Goddard Launched Present-Day Spaceflight

On a snowy day in 1926, a 44-year-old physicist named Robert Goddard went with his wife Esther and some colleagues to his Aunt Effie’s ranch in Auburn, Massachusetts. What happened next was not a typical day on the farm. The group tested the first liquid-fueled rocket.
