A Balancing Act: How Months in Space Impact Astronauts' Performance

When you arrive back on Earth after a year in space, you’re going to feel it.

NASA and Jacob Bloomberg, senior scientist in the Houston, TX- headquartered Johnson Space Center, have been trying to quantify exactly what those effects will be — and how 12 months of microgravity impact an astronaut’s ability to perform simple operational tasks like opening a hatch or climbing a ladder.

Mini Spectrometer Has Big Potential

Researchers have created a miniaturized, portable version of the mass spectrometer, which traditionally has been bulky, limiting its in-field potential. Other smaller spectrometers have been less sensitive and more likely to break down.

Sound-Off: How to Set Pass/Fail Thresholds for Self-Driving Vehicles

As Advanced Driver Assistance System (ADAS) technology evolves, how do you test autonomous cars that ‘learn from their mistakes?’

Coming to a Lab Bench Near You: Femtosecond X-Ray Spectroscopy

The ephemeral electron movements in a transient state of a reaction important in biochemical and optoelectronic processes have been captured and, for the first time, directly characterized using ultrafast X-ray spectroscopy at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). Like many rearrangements of molecular structures, the ring-opening reactions in this study occur on timescales of hundreds of femtoseconds (1 femtosecond equals a millionth of a billionth of a second). The researchers were able to collect snapshots of the electronic structure during the reaction by using femtosecond pulses of X-ray light on a tabletop apparatus.

Infrared 3D Scanner Measures Like Human Vision

A 3D scanner, with a resolution of one million pixels and real-time data processing, operates using measuring technology that works in a similar way to human vision. To detect an object, periodic patterns are projected onto the surface using a specially developed near-infrared projector. A sequence of different patterns is projected in rapid succession in order to record as many measurement points as possible by the two cameras.

Low-Cost Device uses Light to Detect Oil Spills

Researchers have developed a simple device that can detect an oil spill in water and then pinpoint the type of oil present on the surface. The device is designed to float on the water, where it could remotely monitor a small area susceptible to pollution or track the evolution of contamination at a particular location.

Data Logger Aids in Development of New Vehicles

A new data logger developed by Fraunhofer researchers simultaneously collects data from vehicles with combustion engines, electric drives, external sensors, and location data, and permits the development of new hybrid and electric vehicles. Once installed in a car, it records all the relevant operational data from the trips the car makes over a period of several weeks or months, enabling evaluation of how a car is used, including characteristics such as route profiles or driving style – when does the driver drive more cautiously, when more aggressively?

High-Altitude Radiation Tests Will Protect Airline Travelers

Imagine you’re sitting on an airplane cruising at 36,000 feet. Just above you, high-energy particles, called cosmic rays, are zooming in from outer space. While we are largely protected from this radiation on the ground, up in the thin atmosphere of the stratosphere, these particles can affect humans and electronics alike.

Hydraulic Carts Streamline Structural Tests for Aircraft

The Flight Loads Laboratory (FLL) at Armstrong Flight Research Center tests the strength and endurance of aircraft structures using hydraulic actuators to apply forces that simulate the stresses of takeoff, flight, and landing. The contract to build the FLL’s next-generation hydraulic controller system went to Moog Inc., an East Aurora, NY-based company that specializes in motion control systems. The company designed a multi-function mobile cart that not only houses the hydraulics for up to eight actuators, but also includes most of the necessary electronics, which were previously housed in the control room.

Smart Buoy Measures Water Pollutants

Extensive water monitoring is indispensable for drinking water supply and water protection. Researchers have developed a smart monitoring system that combines various technologies in a depth-profile-measuring multi-sensor buoy for monitoring water bodies and algae growth. Conventional monitoring strategies are frequently based on a multitude of independently acting sensor systems. This aggravates and slows down integrated data evaluation.
