Pasadena, CA – Despite large temperature increases in Alaska in recent decades, a new analysis of NASA airborne data finds that methane is not being released from Alaskan soils into the atmosphere at unusually high rates, as recent modeling and experimental studies have suggested.
The new result shows that the changes in this part of the Arctic have not yet had enough impact to affect the global methane budget.

Pasadena, CA – On Wednesday, November 12th, the European Space Agency’s Rosetta mission successfully landed on the surface of comet 67P/Churyumov-Gerasimenko. Descending at a speed of about 2 mph (3.2 kilometers per hour) the lander, called “Philae,” first touched down and its signal was received at 8:03am PST (11:03am EST).
Partially due to anchoring harpoons not firing, and the comet’s low gravity (a hundred-thousand times less than that of Earth), Philae bounced off the surface and flew up to about six-tenths of a mile (1 kilometer) both above the comet’s surface as well as downrange.
NASA’s Cassini Mission data reveals Jupiter’s Red Spot probably created by Chemical reaction to Sunlight
Written by Preston Dyches
Pasadena, 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.

Pasadena, 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.

Pasadena, 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.

Pasadena, 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.

Washington, D.C. – NASA’s Orion spacecraft is set to roll out of the Launch Abort System Facility (LASF) at NASA’s Kennedy Space Center in Florida to its launch pad at nearby Cape Canaveral Air Force Station’s Space Launch Complex 37 on Monday November 10th, in preparation for liftoff next month on its first space flight.
At 4:30pm EST, NASA Television will air a news briefing live from the LASF before Orion’s move. Participating will be Robert Cabana, Kennedy Space Center director; Ellen Ochoa, Johnson Space Center director; Mark Geyer, Orion Program manager; and Mike Hawes, Lockheed Martin Space Systems Company director of Human Space Flight Programs.

Pasadena, CA – Two NASA and one European spacecraft that obtained the first up-close observations of a comet flyby of Mars on October 19th, have gathered new information about the basic properties of the comet’s nucleus and directly detected the effects on the Martian atmosphere.
Data from observations carried out by NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission, NASA’s Mars Reconnaissance Orbiter (MRO), and a radar instrument on the European Space Agency’s (ESA’s) Mars Express spacecraft have revealed that debris from the comet added a temporary and very strong layer of ions to the ionosphere, the electrically charged layer high above Mars.

Pasadena, CA – After sailing through space for more than 10 years, the European Space Agency’s Rosetta spacecraft is now less than a week shy of landing a robotic probe on a comet.
The mission’s Philae (fee-LAY) lander is scheduled to touch down on comet 67P/Churyumov-Gerasimenko on Wednesday, November 12th at 7:35amPST/10:35am EST. A signal confirming the landing is expected about 8:02am PST/11:02am EST.
If all goes as planned with this complex engineering feat, it will be the first-ever soft landing of a spacecraft on a comet.

Pasadena, CA – A NASA sounding rocket experiment has detected a surprising surplus of infrared light in the dark space between galaxies, a diffuse cosmic glow as bright as all known galaxies combined. The glow is thought to be from orphaned stars flung out of galaxies.
The findings redefine what scientists think of as galaxies. Galaxies may not have a set boundary of stars, but instead stretch out to great distances, forming a vast, interconnected sea of stars.
