NASA’s Cassini Mission data reveals Jupiter’s Red Spot probably created by Chemical reaction to Sunlight

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The ruddy color of Jupiter’s Great Red Spot is likely a product of simple chemicals being broken apart by sunlight in the planet’s upper atmosphere, according to a new analysis of data from NASA’s Cassini mission. The results contradict the other leading theory for the origin of the spot’s striking color — that the reddish chemicals come from beneath Jupiter’s clouds.

The results are being presented this week by Kevin Baines, a Cassini team scientist based at NASA’s Jet Propulsion Laboratory, Pasadena, California, at the American Astronomical Society’s Division for Planetary Science Meeting in Tucson, Arizona.

Research suggests effects of sunlight produce the color of Jupiter's Great Red Spot. The feature's clouds are much higher than those elsewhere on the planet, and its vortex nature confines the reddish particles once they form. (NASA/JPL-Caltech/ Space Science Institute)

NASA announces Rosetta Spacecraft’s Philae Lander has made historic touch down on a Comet

NASA - National Aeronautics and Space AdministrationPasadena, CA – After more than a decade traveling through space, a robotic lander built by the European Space Agency has made the first-ever soft landing of a spacecraft on a comet.

Mission controllers at ESA’s mission operations center in Darmstadt, Germany, received a signal confirming that the Philae lander had touched down on comet 67P/Churyumov-Gerasimenko on Wednesday, November 12th, just after 8:00am PST/11:00am EST.

This image of comet 67P/Churyumov-Gerasimenko was taken by the Philae lander of the European Space Agency's Rosetta mission during Philae's descent toward the comet on Nov. 12, 2014. Philae's ROLIS camera took the image from a distance of approximately two miles (three kilometers) from the surface. (ESA/Rosetta/Philae/DLR)

NASA announces Rosetta spacecraft’s lander “Philae” to make historic rendezvous with Comet today

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Early Tuesday morning, the European Space Agency’s Rosetta spacecraft will deploy its comet lander, “Philae.” A little over seven hours later (8:00am PST/11:00am EST), the experiment-laden, harpoon-firing Philae is scheduled to touch down on the surface of comet 67P/Churyumov-Gerasimenko.

It will be the first time in history that a spacecraft has attempted a soft landing on a comet. Rosetta is an international mission led by the European Space Agency (ESA), with instruments provided by its member states, and additional support and instruments provided by NASA.

A Look at Veterans Day History

 

U.S. Department of Veterans AffairsWashington, D.C. – Known at the time as “The Great War”, World War I officially ended when the Treaty of Versailles was signed on June 28th, 1919, in the Palace of Versailles outside the town of Versailles, France.

However, fighting ceased seven months earlier when an armistice, or temporary cessation of hostilities, between the Allied nations and Germany went into effect on the eleventh hour of the eleventh day of the eleventh month. For that reason, November 11th, 1918, is generally regarded as the end of “the war to end all wars.”

Soldiers of the 353rd Infantry near a church at Stenay, Meuse in France, wait for the end of hostilities. This photo was taken at 10:58am, on November 11th, 1918, two minutes before the armistice ending World War I went into effect.

NASA’s Cassini spacecraft finds two new features about Saturn’s moon Titan’s Hydrocarbon Seas

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini mission continues its adventures in extraterrestrial oceanography with new findings about the hydrocarbon seas on Saturn’s moon Titan.

During a flyby in August, the spacecraft sounded the depths near the mouth of a flooded river valley and observed new, bright features in the seas that might be related to the mysterious feature that researchers dubbed the “magic island.”

The findings are being presented this week at the Division for Planetary Sciences Meeting of the American Astronomical Society held in Tucson, Arizona.

U.S. President Barack Obama Urges FCC to Implement Stronger Net Neutrality Rules to keep the Internet Open and Free

 

President of the United States SealWashington, D.C. – Today, President Barack Obama asked the Federal Communications Commission (FCC) to take up the strongest possible rules to protect net neutrality, the principle that says Internet service providers (ISPs) should treat all internet traffic equally.

The President has been a strong and consistent advocate of net neutrality since his first presidential campaign.

President Obama’s plan would reclassify consumer broadband services under what’s known as Title II of the Telecommunications Act.
