Montgomery County Sheriff’s Active Duty K9 Titan Passes Away

 

Montgomery County Sheriff's Office - MCSOClarksville, TN – Montgomery County Sheriff’s Office beloved German Shepard K9 Titan passed way Sunday night from complications from gastric dilatation volvulus surgery.

Titan has been with the Sheriff’s Office since 2014. He was born in Herzebrock-Clarholz, Germany on September 30th, 2011. Before arriving in the United States in 2013, he received his Schutzhund title.

NASA’s Cassini spacecraft examines Methane Sea on Saturn’s moon Titan

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Of the hundreds of moons in our solar system, Titan is the only one with a dense atmosphere and large liquid reservoirs on its surface, making it in some ways more like a terrestrial planet.

Both Earth and Titan have nitrogen-dominated atmospheres — over 95 percent nitrogen in Titan’s case. However, unlike Earth, Titan has very little oxygen; the rest of the atmosphere is mostly methane and trace amounts of other gases, including ethane. And at the frigid temperatures found at Saturn’s great distance from the sun, the methane and ethane can exist on the surface in liquid form.

NASA’s Cassini Spacecraft examines highest mountain on Saturn’s moon Titan

 

Written by Preston Dyches
NASA’a Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – In a nod to extraterrestrial mountaineers of the future, scientists working on NASA’s Cassini mission have identified the highest point on Saturn’s largest moon, Titan.

Titan’s tallest peak is 10,948 feet (3,337 meters) high and is found within a trio of mountainous ridges called the Mithrim Montes. The researchers found that all of Titan’s highest peaks are about 10,000 feet (3,000 meters) in elevation. The study used images and other data from Cassini’s radar instrument, which can peer through the obscuring smog of Titan’s atmosphere to reveal the surface in detail.

NASA’s Cassini Spacecraft to move into higher orbit around Saturn

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini mission is entering its next chapter with an orbital choreography meant to tilt the spacecraft’s orbit out of Saturn’s ringplane.

The second of five large propulsive maneuvers in this campaign took place on Saturday, January 23rd. Each maneuver in the series sets up a subsequent gravity-assist flyby of Saturn’s massive moon Titan, which reshapes the spacecraft’s orbit, sending it to increasingly higher inclination with respect to Saturn’s equator.

Tennessee Titans begin hunt for Head Coach, General Manager

 

Tennessee Titans Football

Tennessee TitansNashville, TN – On Monday, January 4th, 2016, the Tennessee Titans named Steve Underwood Chief of Executive Officer for the franchise.

Underwood has been with the Titan’s organization for 35 years. He served four years as Tennessee’s senior executive vice president and general counsel from 2008-11.

“Today, I am glad to announce that Steve Underwood will be continuing in his role as our president and chief executive officer on a permanent basis,” said Titans Controlling Owner and Co-Chairman of the Board of Directors Amy Adams Strunk.

NASA lists Milky Way Galaxy planets that are remarkably similar to those in the Star Wars universe

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The fantasy creations of the “Star Wars” universe are strikingly similar to real planets in our own Milky Way galaxy. A super Earth in deep freeze? Think ice-planet “Hoth.” And that distant world with double sunsets can’t help but summon thoughts of sandy “Tatooine.”

No indications of life have yet been detected on any of the nearly 2,000 scientifically confirmed exoplanets, so we don’t know if any of them are inhabited by Wookiees or mynocks, or play host to exotic alien bar scenes (or even bacteria, for that matter).

Still, a quick spin around the real exoplanet universe offers tantalizing similarities to several Star Wars counterparts.

The glittering city lights of Coruscant, the Star Wars core world, might have evolved on an older, near Earth-size planet like Kepler-452b. This real-life Earth cousin exists in a system 1.5 billion years older than Earth, giving any theoretical life plenty of time to develop an advanced technological civilization.

NASA’s New Horizons spacecraft discovers Pluto has Blue Skies and Water Ice

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The first color images of Pluto’s atmospheric hazes, returned by NASA’s New Horizons spacecraft last week, reveal that the hazes are blue.

“Who would have expected a blue sky in the Kuiper Belt? It’s gorgeous,” said Alan Stern, New Horizons principal investigator from Southwest Research Institute (SwRI), Boulder, Colorado.

The haze particles themselves are likely gray or red, but the way they scatter blue light has gotten the attention of the New Horizons science team.

Pluto’s Blue Sky: Pluto’s haze layer shows its blue color in this picture taken by the New Horizons Ralph/Multispectral Visible Imaging Camera (MVIC). The high-altitude haze is thought to be similar in nature to that seen at Saturn’s moon Titan. The source of both hazes likely involves sunlight-initiated chemical reactions of nitrogen and methane, leading to relatively small, soot-like particles (called tholins) that grow as they settle toward the surface.

NASA’s Cassini spacecraft data used to analyze Lakes and Seas on Saturn’s Moon Titan

 

Written by Elizabeth Landau / Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Saturn’s moon Titan is home to seas and lakes filled with liquid hydrocarbons, but what forms the depressions on the surface? A new study using data from the joint NASA and the European Space Agency (ESA) Cassini mission suggests the moon’s surface dissolves in a process that’s similar to the creation of sinkholes on Earth.

Apart from Earth, Titan is the only body in the solar system known to possess surface lakes and seas, which have been observed by the Cassini spacecraft. But at Titan’s frigid surface temperatures — roughly minus 292 degrees Fahrenheit (minus 180 degrees Celsius) — liquid methane and ethane, rather than water, dominate Titan’s hydrocarbon equivalent of Earth’s water.

Radar images from NASA's Cassini spacecraft reveal many lakes on Titan's surface, some filled with liquid, and some appearing as empty depressions. (NASA/JPL-Caltech/ASI/USGS)

NASA missions have discovered an abundance of Water in our Solar System

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – As NASA missions explore our solar system and search for new worlds, they are finding water in surprising places. Water is but one piece of our search for habitable planets and life beyond Earth, yet it links many seemingly unrelated worlds in surprising ways.

“NASA science activities have provided a wave of amazing findings related to water in recent years that inspire us to continue investigating our origins and the fascinating possibilities for other worlds, and life, in the universe,” said Ellen Stofan, chief scientist for the agency. “In our lifetime, we may very well finally answer whether we are alone in the solar system and beyond.”

NASA’s Cassini spacecraft’s new orbit to bring it closer to Saturn’s moons

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A dual view of Saturn’s icy moon Rhea marks the return of NASA’s Cassini spacecraft to the realm of the planet’s icy satellites. This follows nearly two years during which the spacecraft’s orbits carried it high above the planet’s poles. Those paths limited the mission’s ability to encounter the moons, apart from regular flybys of Titan.

Cassini’s orbit will remain nearly equatorial for the remainder of 2015, during which the spacecraft will have four close encounters with Titan, two with Dione and three with the geyser-moon, Enceladus.

After a couple of years in high-inclination orbits that limited its ability to encounter Saturn's moons, NASA's Cassini spacecraft returned to Saturn's equatorial plane in March 2015. (NASA/JPL-Caltech/Space Science Institute)
