Testing Astronaut-Controlled Surface Robots from the International Space Station

The National Aeronautics and Space Administration (NASA) and the European Space Agency (ESA) are currently developing robots that can be remotely operated on planetary surfaces by astronauts in orbiting spacecraft. The primary objective of this work is to test and demonstrate crew-controlled communications, operations, and telerobotic technologies that are needed for future deep space human exploration missions. Specifically, NASA’s “Human Exploration Telerobotics” (HET) project and ESA’s “Multi-Purpose End-To-End Robotic Operations Network” (METERON) project are complementary initiatives that aim to validate these technologies through a range of ground and flight experiments with humans and robots in the loop.

Next Generation Non-Destructive Material Analysis - How Handheld FTIR Spectroscopy is Changing Damage and Contamination Analysis, Coating Evaluation, and Material Identification

Handheld FTIR spectroscopy provides a range of new capabilities for non-destructive testing of composites, coatings and polymers. This technique allows the user to take the instrument directly to the object requiring analysis, regardless of its location or size—eliminating the need to transport an object or sample to a traditional lab. Measurements can be made in situ and in real-time, enabling greater flexibility in understanding what and where to measure. It also means that it is not necessary to excise a sample from the object, making handheld FTIR a truly non-destructive testing solution.

High-Speed Imaging: More Than Just Pretty Pictures

We have all seen slow-motion replays in sports broadcast, as well as on TV commercials and popular YouTube channels. Myths have been debunked, water balloons popped, and bullets shot. Watching slow-motion replay of very fast phenomena has led to deeper scientific understanding and breakthrough discoveries. But, there is more to high-speed imaging that slow-motion playback. Camera systems can be integrated with data acquisition to allow the correlation of external measurements to visual feedback; motion analysis tools in playback software can use data in the image to calculate speed, acceleration, angles, and more. And, tracking points in a slow-motion playback can lead to additional visual insights.

Interactive Display Provides Pilots with Real-Time Sonic Boom Information

Ed Haering at NASA's Armstrong Flight Research Center and Ken Plotkin at Wyle have developed a software system capable of displaying the location and intensity of shock waves caused by supersonic aircraft. This technology can be integrated into cockpits or ground-based control rooms to help pilots place any loud booms in a specific location, minimizing their impact in populated areas. The system processes vehicle and flight parameters as well as data regarding current atmospheric conditions. The display provides real-time information regarding sonic boom location and intensity, enabling pilots to make the necessary flight adjustments to control the timing and location of sonic booms. This technology, which will play a key role in enabling supersonic overland flight, can be used on current-generation supersonic aircraft, which generate loud sonic booms, as well as future-generation low-boom aircraft, anticipated to be quiet enough to allow use over populated areas.

Reverse Engineering: The First Step to Efficient Design and Analysis in the Aerospace Industry

Reverse engineering is fast becoming a more popular method of creating 3D data without existing CAD files. This process reconstructs classic designs and implements new ones. It can generate lost or absent design documentation and update or create “as-built” documentation.

Arm Control for World's Largest Functional Brain Model

Spaun, the world's largest functional model of the human brain, has a digital eye, which it uses for visual input, and a robotic arm that it uses to draw its responses. Having a realistic arm that behaves similarly to an actual arm, with appropriate muscle responses and arm segment lengths and mass, is important to getting human-like results.
