Washington, D.C. – Scientists analyzing data from NASA’s Cassini mission have firm evidence of an ocean inside Saturn’s largest moon, Titan, which might be as salty as the Earth’s Dead Sea. The findings are published in this week’s edition of the journal Icarus.
“This is an extremely salty ocean by Earth standards,” said the paper’s lead author, Giuseppe Mitri of the University of Nantes in France. “Knowing this may change the way we view this ocean as a possible abode for present-day life, but conditions might have been very different there in the past.”

Pasadena, CA – NASA successfully launched its first spacecraft dedicated to studying atmospheric carbon dioxide at 2:56am PDT (6:56am CDT) Wednesday.
The Orbiting Carbon Observatory-2 (OCO-2) raced skyward from Vandenberg Air Force Base, California, on a United Launch Alliance Delta II rocket. Approximately 56 minutes after the launch, the observatory separated from the rocket’s second stage into an initial 429-mile (690-kilometer) orbit.

Pasadena, CA – NASA’s Orbiting Carbon Observatory-2 (OCO-2) mission is scheduled to launch from Vandenberg Air Force Base in central California tomorrow, July 1st, at 2:56am PDT (6:56am CDT).
OCO-2 — the first dedicated NASA mission to monitor atmospheric carbon dioxide on global scales — has only a 30-second launch window each day. The launch window is short because the spacecraft needs to be precisely aligned within a series of Earth-observing satellites known as the “A-Train.”

Pasadena, CA – A combined NASA and European Space Agency (ESA)-funded study has found firm evidence that nitrogen in the atmosphere of Saturn’s moon Titan originated in conditions similar to the cold birthplace of the most ancient comets from the Oort cloud.
The finding rules out the possibility that Titan’s building blocks formed within the warm disk of material thought to have surrounded the infant planet Saturn during its formation.

Washington, D.C. – In the lexicon of climate change, one word appears more often than any other: “carbon.” Carbon credits, carbon emissions, carbon sequestration…. These terms are on everyone’s lips.
The reason is carbon dioxide (CO2).
According to the Intergovernmental Panel on Climate Change, CO2 is the most important driver of global warming. At approximately 400 parts per million, atmospheric carbon dioxide is now at its highest level in at least the past 800,000 years.

Pasadena, CA – NASA’s Mars Curiosity rover will complete a Martian year — 687 Earth days — on June 24th, having accomplished the mission’s main goal of determining whether Mars once offered environmental conditions favorable for microbial life.
One of Curiosity’s first major findings after landing on the Red Planet in August 2012 was an ancient riverbed at its landing site. Nearby, at an area known as Yellowknife Bay, the mission met its main goal of determining whether the Martian Gale Crater ever was habitable for simple life forms.

Pasadena, CA – As NASA’s Cassini spacecraft zooms toward Saturn’s smoggy moon Titan for a targeted flyby on June 18th, 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 17th, was one of the most scientifically valuable encounters of the spacecraft’s current extended mission.

Washington, D.C. – With just six months until its first trip to space, NASA’s Orion spacecraft continues taking shape at the agency’s Kennedy Space Center in Florida.
Engineers began stacking the crew module on top of the completed service module Monday, the first step in moving the three primary Orion elements –crew module, service module and launch abort system – into the correct configuration for launch.
NASA’s Space Technology Mission Directorate (STMD) investigates technologies for Human, Robotic missions to Mars
Washington, D.C. – NASA’s Space Technology Mission Directorate (STMD) is paving the way for future Mars exploration. The directorate is currently investing in and developing bold, disruptive technology required for future deep-space missions.
This critical work leads a concerted effort throughout the agency, including at the program level and across multiple centers, as well as with partners in American industry.

Pasadena, CA – Scientists working with data from NASA’s Cassini mission have developed a new way to understand the atmospheres of exoplanets by using Saturn’s smog-enshrouded moon Titan as a stand-in. The new technique shows the dramatic influence that hazy skies could have on our ability to learn about these alien worlds orbiting distant stars.
The work was performed by a team of researchers led by Tyler Robinson, a NASA Postdoctoral Research Fellow at NASA’s Ames Research Center in Moffett Field, California. The findings were published May 26th in the Proceedings of the National Academy of Sciences.
