NASA uses ground based Telescopes to produce images of Peanut shaped Asteroid flyby of Earth

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA scientists have used two giant, Earth-based radio telescopes to bounce radar signals off a passing asteroid and produce images of the peanut-shaped body as it approached close to Earth this past weekend.

The asteroid appears to be a contact binary — an asteroid with two lobes that are stuck together.

The images show the rotation of the asteroid, named 1999 JD6, which made its closest approach on July 24th at 9:55pm PDT (12:55am EDT on July 25th) at a distance of about 4.5 million miles (7.2 million kilometers, or about 19 times the distance from Earth to the moon).

Radar images of asteroid 1999 JD6 were obtained on July 25, 2015. The asteroid is between 660 - 980 feet (200 - 300 meters) in diameter. (NASA/JPL-Caltech/GSSR )

NASA’s Cassini spacecraft photos reveal reddish arcs on Saturn’s ice moon Tethys

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Like graffiti sprayed by an unknown artist, unexplained arc-shaped, reddish streaks are visible on the surface of Saturn’s icy moon Tethys in new, enhanced-color images from NASA’s Cassini spacecraft.

The red arcs are narrow, curved lines on the moon’s surface, and are among the most unusual color features on Saturn’s moons to be revealed by Cassini’s cameras.

Images taken using clear, green, infrared and ultraviolet spectral filters were combined to create the enhanced-color views, which highlight subtle color differences across the icy moon’s surface at wavelengths not visible to human eyes.

Unusual arc-shaped, reddish streaks cut across the surface of Saturn's ice-rich moon Tethys in this enhanced-color mosaic. The red streaks are narrow, curved lines on the moon's surface, only a few miles (or kilometers) wide but several hundred miles (or kilometers) long. (NASA/JPL-Caltech/Space Science Institute)

NASA’s Mars rover Opportunity completes Martian Marathon in 11 years

 

Written by Dr. Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, 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.”

APSU students learn from award winning American slavery scholar Ed Baptist

 

Austin Peay State University - APSUClarksville, 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.

NASA’s Mars Rover Opportunity celebrates surpassing Marathon Distance on March 24th, 2015

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, 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.”

Cumulative driving by NASA's Mars Exploration Rover Opportunity surpassed marathon distance on March 24, 2015, as the rover neared a destination called "Marathon Valley," which is middle ground of this dramatic view from early March. (NASA/JPL-Caltech)

NASA’s Cassini mission images suggests Saturn’s moon Mimas has a frozen core or a liquid ocean

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, 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.

This mosaic of Saturn's moon Mimas was created from images taken by NASA's Cassini spacecraft during its closest flyby of the moon on Feb. 13, 2010. (NASA/JPL-Caltech/Space Science Institute)

NASA’s Cassini Mission has found that Methane Rainfall on Saturn’s moon Titan is being transformed underground lakes

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, 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.

Hundreds of lakes and seas are spread across the surface of Saturn's moon Titan -- its northern polar region in particular. (ESA/ATG medialab)

NASA’s Mars Rover Opportunity explores aluminum mineral rich area on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, 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.
