NASA and Partners Use Sensing Technology to Target Megacities Carbon Emissions

The Megacities Carbon Project is an international, multi-agency pilot initiative to develop and test ways to monitor greenhouse gas emissions in megacities: metropolitan areas of at least 10 million people. Cities and their power plants are the largest sources of human-produced greenhouse gas emissions and are the largest human contributors to climate change.

International Space Station Test Analyzes Rotation of Objects in Space

Objects in space tend to spin in a way that's totally different from the way they spin on Earth. Understanding how objects are spinning, where their centers of mass are, and how their mass is distributed is crucial to any space mission. MIT researchers developed a new algorithm for gauging the rotation of objects in zero gravity using only visual information. They tested the algorithm aboard the International Space Station.

Motion Analysis Detects Joint Degeneration

If joints do no longer work as usual, humans tend to compensate this by unconsciously adapting their motions. In the case of knee arthrosis, or excessive joint wear, they shift the weight to the healthy leg. This relieves the worn knee joint, but also delays the pain that would indicate the start of arthrosis. Based on a computer-supported gait analysis, researchers are developing an early warning system for routine prevention.

3D Printer Heads to International Space Station

The first 3D printer is soon to fly into Earth orbit, finding a home aboard the International Space Station (ISS). The size of a small microwave, the unit is called Portal. The hardware serves as a testbed for evaluating how well 3D printing and the microgravity of space combine. The soon-to-fly 3D printer can churn out plastic objects within a span of 15 minutes to an hour.The technology works by extruding heated plastic, and then builds successive layers to make a three-dimensional object. In essence, the test on the ISS might well lead to establishing a “machine shop” in space. The 3D printer experiment is being done under the tech directorate's Game Changing Development Program, a NASA thrust that seeks to identify and rapidly mature innovative/high impact capabilities and technologies for infusion in a broad array of future NASA missions.According to the team, manufacturing assets in space, as opposed to launching them from Earth, will accelerate and broaden space development while providing unprecedented access for people on Earth to use in-space capabilities.

Custom Surface Inspection System for Safety-Critical Processes

Researchers have engineered a high-precision modular inspection system that can be adapted on a customer-specific basis and integrated into the production process. Before a workpiece leaves the production plant, it is subjected to rigorous inspection. For safety-critical applications such as in the automotive or aerospace industries, manufacturers can only use the most impeccable parts.

New Laser Technology to Make 2020 Mission to Mars

NASA announced recently that laser technology originally developed at Los Alamos National Laboratory has been selected for its new Mars mission in 2020. SuperCam, which builds upon the successful capabilities demonstrated aboard the Curiosity Rover during NASA’s current Mars Mission, will allow researchers to sample rocks and other targets from a distance using a laser.

NASA Begins Engine Test of Space Launch System Rocket

Engineers are preparing to test parts of NASA's Space Launch System (SLS) rocket that will send humans to space. They installed an RS-25 engine on the A-1 Test Stand at Stennis Space Center. The Stennis team will perform developmental and flight certification testing of the RS-25 engine, a modified version of the space shuttle main engine. The SLS's core stage will be powered by a configuration of four RS-25 engines.
