First air-breathing, liquid fuel-powered scramjet takes flight
Before the sun had even risen over Wallops Island, Va., on 10 December 2005, a joint Office of Naval Research/Defense Advanced Research Projects Agency vehicle achieved a world first. At an altitude of 63,000 feet, the Freeflight Atmospheric Scramjet Test Technique (FASTT) vehicle became the first air-breathing, liquid hydrocarbon fuel-powered scramjet engine to fly.
After launching from the NASA Wallops Flight Facility on a two-stage, Terrier-Orion unguided solid-rocket system, the approximately 106-inch long, 11-inch diameter, missile-shaped vehicle raced at 5,300 feet per second (Mach 5.5) for 15 seconds before a controlled splashdown into the Atlantic Ocean. The FASTT vehicle project is part of the joint ONR/DARPA Hypersonic Flight Demonstration (HyFly) program and is designed to demonstrate low-cost flight test techniques and obtain in-flight engine performance data at hypersonic speeds. The overall goal of HyFly is to flight-test key technologies enabling a long range, high-speed cruise missile that can cruise at speeds up to Mach 6.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
