NASA’s Cassini spacecraft discovers deep canyons on Saturn’s moon Titan filled with Hydrocarbons

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini spacecraft has found deep, steep-sided canyons on Saturn’s moon Titan that are flooded with liquid hydrocarbons. The finding represents the first direct evidence of the presence of liquid-filled channels on Titan, as well as the first observation of canyons hundreds of meters deep.

A new paper in the journal Geophysical Research Letters describes how scientists analyzed Cassini data from a close pass the spacecraft made over Titan in May 2013. During the flyby, Cassini’s radar instrument focused on channels that branch out from the large, northern sea Ligeia Mare.

NASA's Cassini spacecraft pinged the surface of Titan with microwaves, finding that some channels are deep, steep-sided canyons filled with liquid hydrocarbons. One such feature is Vid Flumina, the branching network of narrow lines in the upper-left quadrant of the image. (NASA/JPL-Caltech/ASI)

NASA continues to explore our Solar System

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Juno is now poised to shine a spotlight on the origins and interior structure of the largest planet in our solar system.

As we wait for Juno’s first close-up images of Jupiter (to be taken August 27th during the spacecraft’s next pass by the planet), NASA continues to explore our solar system to help answer fundamental questions about how we came to be, where we are going and whether we are alone in the universe.

NASA lists Top 10 things New Horizons Spacecraft has discovered about Pluto

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Where were you at 7:49am Eastern Time on July 14th, 2015?

Three billion miles from Earth, NASA’s New Horizons spacecraft, moving at speeds that would get it from New York to Los Angeles in about four minutes, was pointing cameras, spectrometers, and other sensors at Pluto and its moons – distant worlds that humankind had never seen up close – recording hundreds of pictures and other data that would forever change our view of the outer solar system.

NASA's New Horizons spacecraft captured this high-resolution enhanced color view of Pluto's moon Charon just before closest approach on July 14, 2015. Charon’s striking reddish north polar region is informally named Mordor Macula.(NASA/JHUAPL/SwRI)

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.

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.
