NASA identifies alternate way to collect data from Aura spacecraft’s TES instrument

Pasadena, CA – Mission managers at NASA’s Jet Propulsion Laboratory, Pasadena, California, are evaluating an alternate way to collect and process science data from the Tropospheric Emission Spectrometer (TES) instrument on NASA’s Aura spacecraft following the age-related failure of a critical instrument component.
TES is an infrared sensor designed to study Earth’s troposphere, the lowermost layer of Earth’s atmosphere, which is where we live. Launched in July 2004 and designed to fly for two years, the TES mission is currently in an extended operations phase.

American Stroke Association reports number of Strokes increase as Pollution Levels Rise
Los Angeles, CA – Higher pollution levels were linked to a higher total number of strokes, and researchers said it reaffirmed the growing evidence that climate change and overall air quality contributes to cardiovascular disease, according to research presented at the American Stroke Association’s International Stroke Conference 2016.
The study, which used data from the United States and China, is one of the first to investigate the interaction between air quality and the number of stroke cases (prevalence) along with the potential effect of temperatures on the association.

Tennessee Department of Health says Bicycling and Walking: Healthy for People; Healthy for Tennessee
Nashville, TN – With Tennessee rated the 49th worst state for physical activity and 47th for obesity, one cannot argue about the need for improved health. Tennessee Department of Health Commissioner John Dreyzehner, MD, MPH, believes those ratings can change if state and city leaders increase efforts to make bicycling and walking safer and more convenient.

NASA’s QuikScat satellite finds Beijing China has Quadrupled in Size
Written by Alan Buis
NASA’s Jet Propulsion Laboratory
Pasadena, CA – A new study by scientists using data from NASA’s QuikScat satellite has demonstrated a novel technique to quantify urban growth based on observed changes in physical infrastructure.
The researchers used the technique to study the rapid urban growth in Beijing, China, finding that its physical area quadrupled between 2000 and 2009.
A team led by Mark Jacobson of Stanford University, Palo Alto, California, and Son Nghiem of NASA’s Jet Propulsion Laboratory, Pasadena, California, used data from QuikScat to measure the extent of infrastructure changes, such as new buildings and roads, in China’s capital.
Data from NASA’s QuikScat satellite show the changing extent of Beijing between 2000 and 2009 through changes to its infrastructure. Gray and black indicate buildings, with the tallest and largest buildings in the city’s commercial core appearing lighter gray. Other colors show changes in areas not yet urbanized (for example, clearing land or cutting down trees), with the rate of change indicated by color. Blue-green indicates the least change, yellow-orange more change, and red the greatest change. (NASA/JPL-Caltech)

Tennessee Governor Bill Haslam and Tennessee Department of Environment and Conservation Announces Next Clean Tennessee Energy Grant Cycle
Funding Helps Promote Energy Efficiency Projects, Benefiting the Environment and Bottom Line
Nashville, TN – Tennessee Governor Bill Haslam and Department of Environment and Conservation Commissioner Bob Martineau today announced a second offering of the Clean Tennessee Energy Grants, totaling $2.25 million to fund energy efficiency projects for municipal governments, county governments, utility districts, and other similar entities across Tennessee.
Funding for the projects comes from an April 2011 Clean Air Act settlement with the Tennessee Valley Authority. Under the Consent Decree, Tennessee will receive $26.4 million over five years to fund clean air programs in the state (at approximately $5.25 million per year). As part of the grant program’s initial offering, a total of $5.3 million in Clean Energy Grants was awarded in 2012 to a variety of projects within state government, municipalities, utilities, state colleges and universities and communities throughout the state. «Read the rest of this article»
A Clear Answer to Clean Water
By Dave White, Chief of the Natural Resources Conservation Service (NRCS)
Washington, DC – How important is water? Well, it’s not a question I have to think too hard about. What I can tell you is that without it, there wouldn’t be any humans or critters roaming the earth.
In the U.S., we use a little more than 400 billion gallons of water a day. According to the UN, in the worldwide picture about one in five people lack access to a clean, improved water source.
- Gary, right, and Sue Price have been implementing conservation practices for more than 35 years they on their “77 Ranch” and they have submitted an application for the new national water quality initiative.

Austin Peay State University professor awarded $75K state grant to study health of Red River Watershed
Clarksville, TN – On a spring afternoon in 2010, Dr. Jeff Lebkuecher, professor of biology at Austin Peay State University, waded into a creek to collect algae floating in the water and growing on rocks.
The samples were placed in test tubes, and back in his lab inside the APSU Sundquist Science Complex, Lebkuecher noticed that the algae were thriving. This was not good news for the creek. «Read the rest of this article»
Do you want Foreign Nuclear Waste in TN?
Congresswoman Marsha Blackburn
Marsha Blackburn voted to allow foreign countries to dump their nuclear waste in TN! I don’t think any Tennesseans would agree with that vote. Specifically a company was trying to import 20,000 tons of low level radioactive waste from Italian nuclear facilities for processing. The bill in question banned the importation of nuclear waste.
Members of the House Energy and Commerce Committee approved the bill 34-12 on a mostly party-line vote, with Democrats voting yes and Republicans voting no. Rep. Marsha Blackburn, R-Brentwood, the only other Tennessee member of the committee, voted against the bill.
Her explanation “Blackburn is confident that the foreign waste would have a minimal impact and that processing the material would create jobs in Tennessee”. Blackburn is my representative and I am very unhappy that someone supposedly representing me voted for importing toxic waste into my state. «Read the rest of this article»
