NASA and President Obama are honoring the life and legacy of Sally Ride on the day a national tribute was held for the first American woman in space. The president announced Monday afternoon Ride will be posthumously awarded the Presidential Medal of Freedom during a ceremony at the White House later this year. Monday night, NASA further paid tribute to Ride by creating a new agency internship program in her name and renaming a science instrument aboard the International Space Station.

Curiosity has used the drill on its robotic arm to collect a powdered sample from the interior of a rock called "Cumberland." Plans call for delivering portions of the sample in coming days to laboratory instruments inside the rover. This is only the second time that a sample has been collected from inside a rock on Mars.

NASA's first mission to sample an asteroid is moving ahead into development and testing in preparation for its launch in 2016.

The Origins-Spectral Interpretation Resource Identification Security Regolith Explorer (OSIRIS-REx) passed a confirmation review Wednesday called Key Decision Point (KDP)-C. NASA officials reviewed a series of detailed project assessments and authorized the spacecraft's continuation into the development phase.

How does ice accumulate inside hot turbofan jet engines during flight? NASA scientists at the Glenn Research Center, working with engine manufacturers, are closer to answering that question thanks to the only test facility in the world capable of creating a high altitude ice crystal cloud during a full-scale engine test.

On May 31, 2013, asteroid 1998 QE2 will sail serenely past Earth, getting no closer than about 3.6 million miles (5.8 million kilometers), or about 15 times the distance between Earth and the moon. And while QE2 is not of much interest to those astronomers and scientists on the lookout for hazardous asteroids, it is of interest to those who dabble in radar astronomy and have a 230-foot (70-meter) -- or larger -- radar telescope at their disposal.
