Greenbelt, MD – NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft is nearing its scheduled September 21st insertion into Martian orbit after completing a 10-month interplanetary journey of 442 million miles (711 million kilometers).
Flight Controllers at Lockheed Martin Space Systems in Littleton, Colorado, will be responsible for the health and safety of the spacecraft throughout the process. The spacecraft’s mission timeline will place the spacecraft in orbit at approximately 6:50pm PDT (9:50pm EDT).

Washington, D.C. – On Wednesday morning, October 8th, not long before sunrise, the bright full Moon over North America will turn a lovely shade of celestial red. It’s a lunar eclipse—visible from all parts of the USA.
“It promises to be a stunning sight, even from the most light polluted cities,” says NASA’s longtime eclipse expert Fred Espenak. “I encourage everyone, especially families with curious children, to go out and enjoy the event.”

Pasadena, CA – Our Milky Way galaxy is littered with the still-sizzling remains of exploded stars.
When the most massive stars explode as supernovas, they don’t fade into the night, but sometimes glow ferociously with high-energy gamma rays. What powers these energetic stellar remains?
NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, is helping to untangle the mystery. The observatory’s high-energy X-ray eyes were able to peer into a particular site of powerful gamma rays and confirm the source: A spinning, dead star called a pulsar.

Pasadena, CA – The Dawn spacecraft has resumed normal ion thrusting after the thrusting unexpectedly stopped and the spacecraft entered safe mode on September 11th. That anomaly occurred shortly before a planned communication with NASA’s Deep Space Network that morning. The spacecraft was not performing any special activities at the time.
Engineers immediately began working to restore the spacecraft to its normal operational state. The team determined the source of the problems, corrected them, and then resumed normal ion thrusting on Monday night, September 15th.
Clarksville, TN – American Farmland Trust’s summer celebration of farmers markets has ended and the Clarksville Downtown Market has been recognized as the top farmers market in Tennessee. The Clarksville Downtown Market also came in 19th in the Top 100 Most Celebrated Farmers Markets in America for 2014.
The I Love My Farmers Market Celebration encouraged consumers to pledge to spend $10.00 at their local farmers market. Each pledge honored our nation’s hardworking farmers, our community, and the Clarksville Downtown Market. This year’s celebration helped put more than $400,000 directly into the pockets of family farmers.

Pasadena, CA – The European Space Agency’s Rosetta’s lander, Philae, will target Site J, an intriguing region on comet 67P/Churyumov-Gerasimenko that offers unique scientific potential, with hints of activity nearby, and minimum risk to the lander compared to the other candidate sites.
The 220-pound (100-kilogram) lander is scheduled to reach the surface on November 11th, where it will perform in-depth measurements to characterize the nucleus. Rosetta is an international mission spearheaded by the European Space Agency with support and instruments provided by NASA.
U.S. Senate Passes Legislation Co-sponsored by Lamar Alexander to Improve Emergency Medical Care for More than 600,000 Tennessee Children Every Year
Washington, D.C. – U.S. Senator Lamar Alexander (R-Tennessee) announced that the Senate unanimously passed the Emergency Medical Services for Children Reauthorization Act, legislation he cosponsored to improve emergency medical services for more than 600,000 Tennessee children every year.
This year, the National Pediatric Readiness Assessment ranked Tennessee highest among all states in the ability of its hospital emergency departments to take care of children with emergency conditions.

Pasadena, CA – NASA’s Mars Curiosity rover has reached the Red Planet’s Mount Sharp, a Mount-Rainier-size mountain at the center of the vast Gale Crater and the rover mission’s long-term prime destination.
“Curiosity now will begin a new chapter from an already outstanding introduction to the world,” said Jim Green, director of NASA’s Planetary Science Division at NASA Headquarters in Washington. “After a historic and innovative landing along with its successful science discoveries, the scientific sequel is upon us.”

Washington, D.C. – Fire is inanimate, yet anyone staring into a flame could be excused for thinking otherwise: Fire dances and swirls. It reproduces, consumes matter, and produces waste. It adapts to its environment. It needs oxygen to survive.
In short, fire is uncannily lifelike.
Nowhere is this more true than onboard a spaceship.
Unlike flames on Earth, which have a tear-drop shape caused by buoyant air rising in a gravitational field, flames in space curl themselves into tiny balls.

Pasadena, CA – Compared to the age of the solar system — about four-and-a-half billion years — a couple of decades are next to nothing. Some planetary locales change little over many millions of years, so for scientists who study the planets, any object that evolves on such a short interval makes for a tempting target for study. And so it is with the ever-changing rings of Saturn.
Case in point: Saturn’s narrow, chaotic and clumpy F ring. A recent NASA-funded study compared the F ring’s appearance in six years of observations by the Cassini mission to its appearance during the Saturn flybys of NASA’s Voyager mission, 30 years earlier.
