Pasadena, CA – Three new views of the Martian moon Phobos have been captured by NASA’s Odyssey orbiter. Taken this past winter and this spring, they capture the moon as it drifts into and out of Mars’ shadow.
The orbiter’s infrared camera, the Thermal Emission Imaging System (THEMIS), has been used to measure temperature variations across the surface of Phobos that provide insight into the composition and physical properties of the moon. Further study could help settle a debate over whether Phobos, which is about 16 miles (25 kilometers) across, is a captured asteroid or an ancient chunk of Mars that was blasted off the surface by an impact.
Washington, D.C. – A high-altitude NASA plane is taking off with a new instrument to measure the Moon’s brightness and eventually help Earth observing sensors make more accurate measurements.
The airborne Lunar Spectral Irradiance Instrument (air-LUSI) is flying aboard NASA’s ER-2 airplane. The ER-2 is able to soar above clouds, about 70,000 feet above ground.

Deland, FL – Jenna Panning and Haley Turner of the Austin Peay State University (APSU) beach volleyball team were named to the ASUN Conference’s ten-member All-Academic Team, the league announced Thursday.
Washington, D.C. – In June 2015, when the cameras on NASA’s approaching New Horizons spacecraft first spotted the large reddish polar region on Pluto’s largest moon, Charon, mission scientists knew two things: they’d never seen anything like it elsewhere in our solar system, and they couldn’t wait to get the story behind it.
Over the past year, after analyzing the images and other data that New Horizons has sent back from its historic July 2015 flight through the Pluto system, the scientists think they’ve solved the mystery.

Pasadena, CA – The brightest area on Ceres, located in the mysterious Occator Crater, has the highest concentration of carbonate minerals ever seen outside Earth, according to a new study from scientists on NASA’s Dawn mission. The study, published online in the journal Nature, is one of two new papers about the makeup of Ceres.
“This is the first time we see this kind of material elsewhere in the solar system in such a large amount,” said Maria Cristina De Sanctis, lead author and principal investigator of Dawn’s visible and infrared mapping spectrometer. De Sanctis is based at the National Institute of Astrophysics, Rome.
Washington, D.C. – A year ago, Pluto was just a bright speck in the cameras of NASA’s approaching New Horizons spacecraft, not much different than its appearances in telescopes since Clyde Tombaugh discovered the then-ninth planet in 1930.
But this week, in the journal Science, New Horizons scientists have authored the first comprehensive set of papers describing results from last summer’s Pluto system flyby.

Pasadena, CA – Scientists may be closer to solving the mystery of how Mars changed from a world with surface water billions of years ago to the arid Red Planet of today.
A new analysis of the largest known deposit of carbonate minerals on Mars suggests that the original Martian atmosphere may have already lost most of its carbon dioxide by the era of valley network formation.
“The biggest carbonate deposit on Mars has, at most, twice as much carbon in it as the current Mars atmosphere,” said Bethany Ehlmann of the California Institute of Technology and NASA Jet Propulsion Laboratory, both in Pasadena.

Kennedy Space Center, FL – Fresh food grown in the microgravity environment of space officially is on the menu for the first time for NASA astronauts on the International Space Station. Expedition 44 crew members, including NASA’s one-year astronaut Scott Kelly, are ready to sample the fruits of their labor after harvesting a crop of “Outredgeous” red romaine lettuce Monday, August 10th, from the Veggie plant growth system on the nation’s orbiting laboratory.
The astronauts will clean the leafy greens with citric acid-based, food safe sanitizing wipes before consuming them. They will eat half of the space bounty, setting aside the other half to be packaged and frozen on the station until it can be returned to Earth for scientific analysis.

Pasadena, 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).
Nashville, TN – “Tennessee Uncharted,” the Tennessee Wildlife Resources Agency’s television program, has been named as the best outdoors television series in the country by the Association for Conservation Information, Inc. (ACI).
“Tennessee Uncharted” made its debut in October 2014. TWRA partners with Knoxville-based Designsensory and production company PopFizz to bring the weekly program to television viewers across the state on PBS stations. The program showcases the outdoors, including unique locations, techniques and traditions in the Volunteer State.
