Washington, D.C. – On Earth, the fastest runners can finish a marathon in hours. On Mars it takes about 11 years.
On Tuesday, March 24th 2015, NASA’s Mars rover Opportunity completed its first Red Planet marathon– 26.219 miles – with a finish time of roughly 11 years and two months.
“This mission isn’t about setting distance records; it’s about making scientific discoveries,” says Steve Squyres, Opportunity principal investigator at Cornell University. “Still, running a marathon on Mars feels pretty cool.”
Clarksville, TN – Slavery in the United States was officially abolished on December 6th, 1865 when the thirteenth amendment was ratified by three-fourth of the states. But while all remaining slaves became officially free on that day, the ripples from the United States’ violent history continue to be felt to this day.
Austin Peay State University students recently had an opportunity to converse with one of the preeminent experts on the history of slavery in the United States when they participated in an online question and answer session with journalist, and Cornell University history professor, Ed Baptist.

Pasadena, CA – There was no tape draped across a finish line, but NASA is celebrating a win. The agency’s Mars Exploration Rover Opportunity completed its first Red Planet marathon Tuesday — 26.219 miles (42.195 kilometers) – with a finish time of roughly 11 years and two months.
“This is the first time any human enterprise has exceeded the distance of a marathon on the surface of another world,” said John Callas, Opportunity project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California. “A first time happens only once.”

Pasadena, CA – A new study focused on the interior of Saturn’s icy moon Mimas suggests its cratered surface hides one of two intriguing possibilities: Either the moon’s frozen core is shaped something like a football, or the satellite contains a liquid water ocean.
Researchers used numerous images of Mimas taken by NASA’s Cassini mission to determine how much the moon wobbles as it orbits Saturn. They then evaluated several possible models for how its interior might be arranged, finding two possibilities that fit their data.The study is published in the October 17th issue of the journal Science.
NASA’s Cassini Mission has found that Methane Rainfall on Saturn’s moon Titan is being transformed underground lakes
Written by Preston Dyches
Pasadena, CA – The NASA and European Space Agency Cassini mission has revealed hundreds of lakes and seas spread across the north polar region of Saturn’s moon Titan. These lakes are filled not with water but with hydrocarbons, a form of organic compound that is also found naturally on Earth and includes methane.
The vast majority of liquid in Titan’s lakes is thought to be replenished by rainfall from clouds in the moon’s atmosphere. But how liquids move and cycle through Titan’s crust and atmosphere is still relatively unknown.

Pasadena, CA – With its solar panels their cleanest in years, NASA’s decade-old Mars Exploration Rover Opportunity is inspecting a section of crater-rim ridgeline chosen as a priority target due to evidence of a water-related mineral.
Orbital observations of the site by another NASA spacecraft, Mars Reconnaissance Orbiter, found a spectrum with the signature of aluminum bound to oxygen and hydrogen. Researchers regard that signature as a marker for a mineral called montmorillonite, which is in a class of clay minerals called smectites.
Clarksville, TN – This summer, Matthew Martin’s budding interest in plants will send him to the Ivy League campus of Cornell University where he’ll conduct advanced research in the field of plant pathology.
The Austin Peay State University student is getting this rare opportunity thanks to Cornell’s competitive Microbial Friends and Foes Research Experience for Undergraduates (REU) program. «Read the rest of this article»

Pasadena, CA – Ten years ago, we knew Titan as a fuzzy orange ball about the size of Mercury. We knew it had a nitrogen atmosphere — the only known world with a thick nitrogen atmosphere besides Earth. But what might lie beneath the hazy air was still just a guess.
On March 6th, NASA’s Cassini spacecraft will swoop down within 933 miles (1,500 kilometers) of Titan to conduct its 100th flyby of the Saturn moon. Each flyby gives us a little more knowledge of Titan and its striking similarities to our world.

Washington, D.C. – New findings from rock samples collected and examined by NASA’s Mars Exploration Rover Opportunity have confirmed an ancient wet environment that was milder and older than the acidic and oxidizing conditions told by rocks the rover examined previously.
In the January 24th edition of the journal Science, Opportunity Deputy Principal Investigator Ray Arvidson, a professor at Washington University in St. Louis, writes in detail about the discoveries made by the rover and how these discoveries have shaped our knowledge of the planet. According to Arvidson and others on the team, the latest evidence from Opportunity is landmark.
