Preston Dyches, Jet Propulsion Laboratory As NASA’s Cassini spacecraft zooms toward Saturn’s smoggy moon Titan for a targeted flyby on June 18, mission scientists are excitedly hoping to repeat a scientific tour de force that will provide valuable new insights into the nature of the moon's surface and atmosphere. For Cassini’s radio science team, the last flyby of Titan, on May 17, was one of the most scientifically valuable encounters of the spacecraft’s current extended...

Elizabeth Zubritzky, NASA's Goddard Space Flight Center NASA scientists have created a new recipe that captures key flavors of the brownish-orange atmosphere around Saturn’s largest moon, Titan. The recipe is used for lab experiments designed to simulate Titan’s chemistry. With this approach, the team was able to classify a previously unidentified material discovered by NASA’s Cassini spacecraft in the moon’s smoggy haze. “Now we can say that this material has a strong...

Gerard LeBlond for redOrbit.com - Your Universe Online An asteroid, designated “2014 HQ124” at least 1,200 feet wide on its long axis, passed by Earth on June 8, 2014. It came within 776,000 miles, or approximately three times the distance to the moon. Images captured of the asteroid are some of the most detailed in NASA’s history. The asteroid was first spotted on April 23, 2014 by NASA’s NEOWISE mission. NEOWISE was adapted for capturing infrared light emitted from comets and...

NASA NASA’s first spacecraft dedicated to measuring carbon dioxide levels in Earth’s atmosphere is in final preparations for a July 1 launch from Vandenberg Air Force Base, California. [ Watch the Video: OCO-2: NASA’s Carbon Counter ] The Orbiting Carbon Observatory-2 (OCO-2) mission will provide a more complete, global picture of the human and natural sources of carbon dioxide, as well as their “sinks,” the natural ocean and land processes by which carbon dioxide is pulled...

Rosetta at Comet
2014-06-10 16:21:28

NASA Three NASA science instruments aboard the European Space Agency's (ESA) Rosetta spacecraft, which is set to become the first to orbit a comet and land a probe on its nucleus, are beginning observations and sending science data back to Earth. Launched in March 2004, Rosetta was reactivated in January 2014 after a record 957 days in hibernation. Composed of an orbiter and lander, Rosetta's objective is to arrive at comet 67P/Churyumov-Gerasimenko in August to study the celestial...
