Augmented reality helps build aircraft tanks

Through ambient markers on the tank the AR glasses know where the tank is and how large it is, allowing them to project a 3-D model. Credit: Markus Breig, KIT Walking through an unfamiliar city, getting directions or simulations of buildings that no longer exist – augmented reality is where virtual content and the real world come together. Scientists at Karlsruhe Institute of Technology (KIT) are developing an assistance system based on this technology which supports engineers in building and…

Checking China’s pollution by satellite — ScienceDaily

Air pollution has smothered China’s cities in recent decades. In response, the Chinese government has implemented measures to clean up its skies. But are those policies effective? Now an innovative study co-authored by an MIT scholar shows that one of China’s key antipollution laws is indeed working — but unevenly, with one particular set of polluters most readily adapting to it. The study examines a Chinese law that has required coal-fired power plants to significantly reduce emissions of sulfur dioxide,…

Preventing a plane crash—research helps pilots train for aerodynamic stalls

Credit: Marit Mitchell On a winter night in February 2009, Colgan Air Flight 3407 crashed just outside of Buffalo, N.Y., killing all 49 passengers and crew aboard and one person on the ground. An investigation by the National Transportation Safety Board determined that the turbo-prop aircraft experienced many factors contributing to the crash, including an…

NASA finds ancient organic material, mysterious methane on Mars — ScienceDaily

NASA’s Curiosity rover has found new evidence preserved in rocks on Mars that suggests the planet could have supported ancient life, as well as new evidence in the Martian atmosphere that relates to the search for current life on the Red Planet. While not necessarily evidence of life itself, these findings are a good sign for future missions exploring the planet’s surface and subsurface. The new findings — “tough” organic molecules in 3-billion-year-old sedimentary rocks near the surface, as well…

Electric test plane crashes in Hungary killing two

The remains of an electric plane powered by Siemens that crashed during a test flight in Hungary, killing both pilots An electric plane powered by Siemens crashed during a test flight in Hungary, killing both pilots on board, the German industrial conglomerate said Wednesday. Siemens said it had grounded its fleet of Magnus eFusion aircraft “as a precautionary measure” following the May 31 incident at an airfield near Budapest. “We can confirm that an accident happened to an experimental…

MAE doctoral candidate earns prestigious MU award

Engineers aim for the stars with new rocket engine

Credit: University of Glasgow A ‘self-eating’ rocket engine which could place small satellites in orbit more easily and more affordably is under development at universities in Scotland and Ukraine. In a paper published in the Journal of Spacecraft and Rockets, engineers from the University of Glasgow and Oles Honchar Dnipro National University in Ukraine discuss how they have built, fired, and for the first time throttled up and down an ‘autophage’ engine which could change how small satellites are sent…

First-of-its-kind study combines NASA satellite observations of Earth with data on human activities to map where–and why–freshwater is changing around the globe — ScienceDaily

A new global, satellite-based study of Earth’s freshwater distribution found that Earth’s wet areas are getting wetter, while dry areas are getting drier. The data suggest that this pattern is due to a variety of factors, including human water management practices, human-caused climate change and natural climate cycles. The NASA-led research team, which included Hiroko Beaudoing, a faculty specialist at the University of Maryland’s Earth System Science Interdisciplinary Center (ESSIC), used 14 years of observations from the Gravity Recovery and…

Ocean evaporation matched up with massive overland rainfall — ScienceDaily

In the weeks before Hurricane Harvey tore across the Gulf of Mexico and plowed into the Texas coast in August 2017, the Gulf’s waters were warmer than any time on record, according to a new analysis led by the National Center for Atmospheric Research (NCAR). These hotter-than-normal conditions supercharged the storm, fueling it with vast stores of moisture, the authors found. When it stalled near the Houston area, the resulting rains broke precipitation records and caused devastating flooding. “We show,…
