Pasadena, CA – Images taken with a telephoto-lens camera on NASA’s Mars rover Curiosity catch the larger of Mars’ two moons, Phobos, passing directly in front of the sun — the sharpest images of a solar eclipse ever taken at Mars.
Phobos does not fully cover the sun, as seen from the surface of Mars, so the solar eclipse is what’s called a ring, or annular, type. A set of three frames from Curiosity’s Mast Camera (Mastcam), taken three seconds apart as Phobos eclipsed the sun here .
Pasadena, CA – The larger of the two moons of Mars, Phobos, passes directly in front of the other, Deimos, in a new series of sky-watching images from NASA’s Mars rover Curiosity.
Large craters on Phobos are clearly visible in these images from the surface of Mars. No previous images from missions on the surface caught one moon eclipsing the other.
Montgomery County, TN – Director of Schools Dr. B. J. Worthington was presented with the Bob Grossman Leadership in School Communications Award last week by the National School Public Relations Association at its 60th annual national seminar in San Diego, CA.
Worthington’s selection recognizes him as practicing superintendent of schools or CEO of an education agency, service center or intermediate unit for outstanding leadership in school public relations and communication.

Pasadena, CA – Gone are the days of being able to count the number of known planets on your fingers. Today, there are more than 800 confirmed exoplanets — planets that orbit stars beyond our sun — and more than 2,700 other candidates.
What are these exotic planets made of? Unfortunately, you cannot stack them in a jar like marbles and take a closer look. Instead, researchers are coming up with advanced techniques for probing the planets’ makeup.

Pasadena, CA – NASA’s Kepler space telescope has witnessed the effects of a dead star bending the light of its companion star. The findings are among the first detections of this phenomenon — a result of Einstein’s general theory of relativity — in binary, or double, star systems.
The dead star, called a white dwarf, is the burnt-out core of what used to be a star like our sun. It is locked in an orbiting dance with its partner, a small “red dwarf” star. While the tiny white dwarf is physically smaller than the red dwarf, it is more massive.
Part of Wider Effort to Protect Taxpayers, Prevent Refund Fraud
Washington, D.C. – Continuing a year-long enforcement push against refund fraud and identity theft, the Internal Revenue Service today announced the results of a massive national sweep in recent weeks targeting identity theft suspects in 32 states and Puerto Rico, which involved 215 cities and surrounding areas.
The coast-to-coast effort against 389 identity theft suspects led to 734 enforcement actions in January, including indictments, informations, complaints and arrests. The effort comes on top of a growing identity theft effort that led to 2,400 other enforcement actions against identity thieves during fiscal year 2012.

Pasadena, CA – NASA’s Mars rover Curiosity has for the first time used the camera on its arm to take photos at night, illuminated by white lights and ultraviolet lights on the instrument.
Scientists used the rover’s Mars Hand Lens Imager (MAHLI) instrument for a close-up nighttime look at a rock target called “Sayunei,” in an area where Curiosity’s front-left wheel had scuffed the rock to provide fresh, dust-free materials to examine.

Pasadena, CA – NASA has named the site where twin agency spacecraft impacted the moon Monday in honor of the late astronaut Sally K. Ride, who was America’s first woman in space and a member of the probes’ mission team.
Last Friday, Ebb and Flow, the two spacecraft comprising NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission, were commanded to descend into a lower orbit that would result in an impact Monday on a mountain near the moon’s north pole.

Pasadena, CA – NASA’s Mars Curiosity rover has used its full array of instruments to analyze Martian soil for the first time, and found a complex chemistry within the Martian soil. Water and sulfur and chlorine-containing substances, among other ingredients, showed up in samples Curiosity’s arm delivered to an analytical laboratory inside the rover.
Detection of the substances during this early phase of the mission demonstrates the laboratory’s capability to analyze diverse soil and rock samples over the next two years. Scientists also have been verifying the capabilities of the rover’s instruments.

Pasadena, CA – A Martian dust storm that NASA’s Mars Reconnaissance Orbiter has been tracking since last week has also produced atmospheric changes detectable by rovers on Mars.
Using the orbiter’s Mars Color Imager, Bruce Cantor of Malin Space Science Systems, San Diego, began observing the storm on November 10th, and subsequently reported it to the team operating NASA’s Mars Exploration Rover Opportunity.
The storm came no closer than about 837 miles (1,347 kilometers) from Opportunity, resulting in only a slight drop in atmospheric clarity over that rover, which does not have a weather station.
