NASA’s Cassini Spacecraft to begin first phase of it’s end mission

 

Written by Preston Dyches

NASA - National Aeronautics and Space AdministrationPasadena, CA – A thrilling ride is about to begin for NASA’s Cassini spacecraft. Engineers have been pumping up the spacecraft’s orbit around Saturn this year to increase its tilt with respect to the planet’s equator and rings. And on November 30th, following a gravitational nudge from Saturn’s moon Titan, Cassini will enter the first phase of the mission’s dramatic endgame.

Launched in 1997, Cassini has been touring the Saturn system since arriving there in 2004 for an up-close study of the planet, its rings and moons. During its journey, Cassini has made numerous dramatic discoveries, including a global ocean within Enceladus and liquid methane seas on Titan.

NASA’s Cassini Spacecraft observes Methane Clouds moving across Saturn’s moon Titan

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini spacecraft watched clouds of methane moving across the far northern regions of Saturn’s largest moon, Titan, on October 29­­­­th and 30th, 2016.

Several sets of clouds develop, move over the surface and fade during the course of this movie sequence, which spans 11 hours, with one frame taken every 20 minutes. Most prominent are long cloud streaks that lie between 49 and 55 degrees north latitude.

NASA’s Cassini Spacecraft observes Changes of Seasons on Saturn’s moon Titan

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – As southern winter solstice approaches in the Saturn system, NASA’s Cassini spacecraft has been revealing dramatic seasonal changes in the atmospheric temperature and composition of Saturn’s largest moon, Titan.

Winter is taking a grip on Titan’s southern hemisphere, and a strong, whirling atmospheric circulation pattern — a vortex — has developed in the upper atmosphere over the south pole. Cassini has observed that this vortex is enriched in trace gases — gases that are otherwise quite rare in Titan’s atmosphere. Cassini’s observations show a reversal in the atmosphere above Titan’s poles since the spacecraft arrived at Saturn in 2004, when similar features were seen in the northern hemisphere.

NASA’s Cassini Spacecraft observes Mystery Cloud on Saturn’s moon Titan

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The puzzling appearance of an ice cloud seemingly out of thin air has prompted NASA scientists to suggest that a different process than previously thought — possibly similar to one seen over Earth’s poles — could be forming clouds on Saturn’s moon Titan.

Located in Titan’s stratosphere, the cloud is made of a compound of carbon and nitrogen known as dicyanoacetylene (C4N2), an ingredient in the chemical cocktail that colors the giant moon’s hazy, brownish-orange atmosphere.

NASA’s Cassini spacecraft images reveals Dunes on Saturn’s moon Titan

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – New scenes from a frigid alien landscape are coming to light in recent radar images of Saturn’s largest moon, Titan, from NASA’s Cassini spacecraft.

Cassini obtained the views during a close flyby of Titan on July 25th, when the spacecraft came as close as 607 miles (976 kilometers) from the giant moon. The spacecraft’s radar instrument is able to penetrate the dense, global haze that surrounds Titan, to reveal fine details on the surface.

This synthetic-aperture radar (SAR) image was obtained by NASA's Cassini spacecraft on July 25, 2016, during its "T-121" pass over Titan's southern latitudes. (NASA/JPL-Caltech/ASI/Université Paris-Diderot)

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

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

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 Headquarters

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)
