The company’s soon-to-be local plant manager, Gerald Craycraft, met with the Industrial Development Board this week to announce new improvements and new product lines to Shiloh’s original plans since purchasing Contech in August 2013. ![]() IDB Chairman Billy Atkins and Shiloh Plant Manager Gerald Craycraft hold a magnesium dashboard panel manufactured at the Shiloh plant in Ireland. «Read the rest of this article» Sections: Business | No Comments
NASA announces NOAA’s GOES-16 Satellite takes First Photos of EarthWritten by John Leslie
Created using several of the ABI’s 16 spectral channels, the full-disk image offers an example the satellite’s advanced technology. ![]() This composite color full-disk visible image of the Western Hemisphere was captured from NOAA GOES-16 satellite at 1:07 pm EST on Jan. 15, 2017 and created using several of the 16 spectral channels available on the satellite’s sophisticated Advanced Baseline Imager. The image, taken from 22,300 miles above the surface, shows North and South America and the surrounding oceans. (NOAA) «Read the rest of this article» Sections: Technology | No Comments
NASA’s AIRS Instrument Tracks Series of Storms Battering CaliforniaWritten by Alan Buis
The images of atmospheric water vapor were collected by AIRS between January 7th and 11th. They show the amount of moisture present in the atmosphere and its movement across the Pacific Ocean to the United States, where much of it fell as rain or snow. ![]() A series of atmospheric rivers that brought drought-relieving rains, heavy snowfall and flooding to California this week is highlighted in a new movie created with satellite data from the Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua satellite.

APSU College of Education prepares local teachers for 2017 Solar Eclipse
More than 4,000 years ago, Chung K’ang, the fourth emperor of the Hea dynasty in China, reportedly executed two astronomers named Hi and Ho because they didn’t predict a solar eclipse. ![]() Tennessee State Representative Joe Pitts tries out a pair of solar glasses during a recent educational summit at APSU. «Read the rest of this article» Sections: Education | No Comments
NASA to use Spacecraft Orbiting Earth to track Air PollutionWritten by Steve Cole
We are getting close. Air pollution causes an estimated 152,000 deaths a year across the Americas and more than 2 million deaths in the Western Pacific, according to the United Nations. Some parts of the world have a detailed view of local air quality from ground sensor networks and forecast models that generate public alerts. But for much of the world this type of information and warning are not available. ![]() Satellites have documented that human-produced and natural air pollution can travel a long way. This 2014 NASA satellite image shows a long river of dust from western Africa (bottom of image) push across the Atlantic Ocean.

NASA uses satellite data to solve questions about Earth’s rotational wobblesWritten by Alan Buis
Although a desktop globe always spins smoothly around the axis running through its north and south poles, a real planet wobbles. Earth’s spin axis drifts slowly around the poles; the farthest away it has wobbled since observations began is 37 feet (12 meters). ![]() Earth does not always spin on an axis running through its poles. Instead, it wobbles irregularly over time, drifting toward North America throughout most of the 20th Century (green arrow). That direction has changed drastically due to changes in water mass on Earth. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA researchers explore growing Food Crops during long Deep Space MissionsWritten by Linda Herridge
“The Martian movie and book conveyed a lot of issues regarding growing food and surviving on a planet far from the Earth,” Wheeler said. “It’s brought plants back into the equation.” ![]() An artist concept depicts a greenhouse on the surface of Mars. Plants are growing with the help of red, blue and green LED light bars and a hydroponic cultivation approach. (SAIC) «Read the rest of this article» Sections: Technology | No Comments
NASA reports a strong, growing El Niño head to United StatesWritten by Alan Buis
El Niño 2015 has already created weather chaos around the world. Over the next few months, forecasters expect the United States to feel its impacts as well. The latest Jason-2 image bears a striking resemblance to one from December 1997, by Jason-2’s predecessor, the NASA/Centre National d’Etudes Spatiales (CNES) Topex/Poseidon mission, during the last large El Niño event. Both reflect the classic pattern of a fully developed El Niño. The images can be viewed at: ![]() The latest satellite image of Pacific sea surface heights from Jason-2 (left) differs slightly from one 18 years ago from Topex/Poseidon (right). In Dec. 1997, sea surface height was more intense and peaked in November. This year the area of high sea levels is less intense but considerably broader.

NASA examines Carbon emissions across the Earth to better understand our warming climateWritten by Kate Ramsayer, NASA Goddard Space Flight Center
As carbon dioxide levels in the atmosphere continue their rapid, human-made rise past levels not seen for hundreds of thousands of years, NASA scientists and others are confronted with an important question for the future of our planet: How long can this balancing act continue? And if forests, other vegetation and the ocean cannot continue to absorb as much or more of our carbon emissions, what does that mean for the pace of climate change in the coming century? ![]() NASA is advancing new tools like the supercomputer model that created this simulation of carbon dioxide in the atmosphere to better understand what will happen to Earth’s climate if the land and ocean can no longer absorb nearly half of all climate-warming CO2 emissions.

NASA sets the stage for upcoming Super Harvest Moon EclipseScience at NASA
According to folklore, the Harvest Moon is the full Moon that falls closest to the autumnal equinox, the hectic beginning of northern autumn. In 2015, the Moon is full on September 28th, less than a week after the equinox of September 23rd. The coincidence sets the stage for a nice display of harvest moonlight. «Read the rest of this article» Sections: Technology | No Comments
