NASA’s Cassini spacecraft data reveals Saturn Storm’s Power churns up ice water

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – A monster storm that erupted on Saturn in late 2010 – as large as any storm ever observed on the ringed planet — has already impressed researchers with its intensity and long-lived turbulence.

A new paper in the journal Icarus reveals another facet of the storm’s explosive power: its ability to churn up water ice from great depths. This finding, derived from near-infrared measurements by NASA’s Cassini spacecraft, is the first detection at Saturn of water ice. The water originates from deep in Saturn’s atmosphere.

This set of images from NASA's Cassini mission shows the turbulent power of a monster Saturn storm. The visible-light image in the back, obtained on Feb. 25, 2011, by Cassini's imaging camera, shows the turbulent clouds churning across the face of Saturn. The inset infrared image, obtained a day earlier, by Cassini's visual and infrared mapping spectrometer, shows the dredging up of water and ammonia ices from deep in Saturn's atmosphere.

NASA’s Cassini spacecraft observes Storm on Saturn devour itself

NASA - National Aeronautics and Space AdministrationPasadena, CA – Call it a Saturnian version of the Ouroboros, the mythical serpent that bites its own tail. In a new paper that provides the most detail yet about the life and death of a monstrous thunder-and-lightning storm on Saturn, scientists from NASA’s Cassini mission describe how the massive storm churned around the planet until it encountered its own tail and sputtered out.

It is the first time scientists have observed a storm consume itself in this way anywhere in the solar system.

This set of images from NASA's Cassini mission shows the evolution of a massive thunder-and-lightning storm that circled all the way around Saturn and fizzled when it ran into its own tail. The storm was first detected on Dec. 5th, 2010. That month, it developed a head of bright clouds quickly moving west and spawned a much slower-drifting clockwise-spinning vortex.

NASA’s Cassini spacecraft sees record disturbances on Saturn in aftermath of Large Storm

 

Written by Jia-Rui C. Cook
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini spacecraft has tracked the aftermath of a rare massive storm on Saturn. Data reveal record-setting disturbances in the planet’s upper atmosphere long after the visible signs of the storm abated, in addition to an indication the storm was more forceful than scientists previously thought.

Data from Cassini’s composite infrared spectrometer (CIRS) instrument revealed the storm’s powerful discharge sent the temperature in Saturn’s stratosphere soaring 150 degrees Fahrenheit (83 kelvins) above normal.

These red, orange and green clouds (false color) in Saturn's northern hemisphere indicate the tail end of a massive storm that started in December 2010. Even after visible signs of the storm started to fade, infrared measurements continued to reveal powerful effects at work in Saturn's stratosphere.

NASA’s Cassini Chronicles Life of Saturn’s Giant Storm

 

Written by Jia-Rui Cook
Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – New images and animated movies from NASA’s Cassini spacecraft chronicle the birth and evolution of the colossal storm that ravaged the northern face of Saturn for nearly a year.

These new full-color mosaics and animations show the storm from its emergence as a tiny spot in a single image almost one year ago, on December 5th, 2010, through its subsequent growth into a storm so large it completely encircled the planet by late January 2011.

The monster tempest, which extended north-south approximately 9,000 miles (15,000 kilometers), is the largest seen on Saturn in the past two decades and is the largest by far ever observed on the planet from an interplanetary spacecraft.

LEAP Interns reach out to Storm Victims

 

LEAP OrganizationClarksville, TN – The L.E.A.P. ORG. not only operates by the 7 points of Leadership, Enlightenment, Academic Achievement, Perseverance, Outreach, Responsibility, and Growth, but also instills these attributes in the interns being mentored.

Daquan Orebo (17) and Ralphie Armstrong (12) participate in the LEAP lawn Care Service. Due to the severe storm resulting in several of the clients trees falling in the back yard with a host of  limbs and branches scattered throughout the lawn, they were advised to just cut the front yard.
