Self-Healing Spacecraft Material Plugs Holes in Seconds

Although shields and sophisticated maneuvers could help protect space structures, scientists have to prepare for the possibility that debris could pierce a vessel. NASA and a team from the University of Michigan developed a new material that heals itself within seconds and could prevent structural penetration from being catastrophic.

'Snap' Design Mimics Venus Flytrap

A team led by physicist Christian Santangelo at the University of Massachusetts Amherst uses curved creases to give thin shells a fast, programmable snapping motion. The technique – inspired by the natural "snapping systems" like Venus flytrap leaves and hummingbird beaks – avoids the need for complicated materials and fabrication methods when creating structures with fast dynamics.

Depth-Sensing Camera Works in Bright Light and Darkness

A new imaging technology from Carnegie Mellon University and the University of Toronto operates in both bright sunlight and darkness. A mathematical model programs the device so that the camera and its light source work together efficiently, eliminating extraneous light, or “noise,” that would otherwise wash out the signals needed to detect a scene’s contours.

Crash Test Helps Improve Emergency Response

NASA’s Langley Research Center hoisted a Cessna 172 aircraft 100 feet into the air by cables and released it. The plane plummeted onto a slab of dirt in a violent but controlled experiment that will help NASA improve aviation emergency response times. The test is part of a push to bolster the reliability of emergency locator transmitters. The systems automatically alert rescue personnel in the event of an airplane crash.

Database Could Make Airport Ground Movements Quicker and Greener

Growth in air traffic and passenger numbers has led to warnings that airports could become bottlenecks in the global air transportation system. Ensuring efficient movement of aircraft on the ground is a key way for airport stakeholders to save time, reduce costs, and improve carbon emissions. Aviation engineering specialists have created an innovative system for airport ground movement to generate the most efficient routes and optimal speed instructions – or speed profiles – for pilots to follow during taxiing.

Thin Ribbon of Flexible Electronics Monitors Aircraft Health

A hybrid technology mixes traditional electronics with flexible, high-performance electronics and new 3D printing technologies. The system takes a razor-thin silicon integrated circuit and places it on a flexible, bendable, or even foldable plastic-like material. The circuitry can fit into extremely tight spaces, and even can be integrated into complex curved surfaces such as an airplane’s wing.

Robotic System Builds Biggest Composite Rocket Parts Ever Made

One of the largest composites manufacturing robots created in America will help NASA build the biggest lightweight composite parts ever made for space vehicles. The robot will build structures larger than 26 feet in diameter. The robot travelled across the country from Electroimpact, Inc. in Mukilteo, WA. Electroimpact engineers worked with NASA Marshall engineers to customize the robot and supporting software for building large space structures.
