Statements on NASA Deputy Administrator Lori Garver's Announced Departure

The following are statements from NASA Administrator Charles Bolden and Office of Science and Technology Policy Director John Holdren about NASA Deputy Administrator Lori Garver's announced departure from the agency, effective Sept. 6.

3D IR images now in full color

An iconic moment in the history of Hollywood movie magic was born in the 1939 film The Wizard of Oz when Judy Garland as Dorothy Gale stepped out of the black and white world of Kansas into the rainbow colored world of Oz. An iconic moment in the history of infrared imaging may have been born with the announcement of the first technique to offer full color IR tomography.

Making a mini Mona Lisa: Nanotechnique creates image on surface less than a third the hair's width

Scientists have "painted" the Mona Lisa on a substrate surface approximately 30 microns in width -- or one-third the width of a human hair. The team's creation, the "Mini Lisa," demonstrates a technique that could potentially be used to achieve nanomanufacturing of devices because the team was able to vary the surface concentration of molecules on such short-length scales.

Interface superconductivity withstands variations in atomic configuration

Scientists discover that critical temperature remains constant across interface superconductors regardless of changes in electron doping levels, challenging leading theories.

A layer of tiny grains can slow sound waves

In some ways, granular material—such as a pile of sand—can behave much like a crystal, with its close-packed grains mimicking the precise, orderly arrangement of crystalline atoms. Now researchers at MIT have pushed that similarity to a new limit, creating two-dimensional arrays of micrograins that can funnel acoustic waves, much as specially designed crystals can control the passage of light or other waves.

An infallible quantum measurement

For quantum physicists, entangling quantum systems is one of their every day tools. Entanglement is a key resource for upcoming quantum computers and simulators. Now, physicists in Austria and Switzerland have developed a new, reliable method to verify entanglement in the laboratory using a minimal number of assumptions about the system and measuring devices.

NASA Selects Launch Services Contract for OSIRIS-REx Mission

NASA has selected United Launch Services LLC of Englewood, Colo. to launch the Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REx) spacecraft.

NASA Begins Launch Preparations for Next Mars Mission

NASA's next spacecraft going to Mars arrived Friday, Aug. 2, at the agency's Kennedy Space Center in Florida, and is now perched in a cleanroom to begin final preparations for its November launch.

NASA Television to Broadcast Two Russian Spacewalks in August

NASA Television will provide live coverage as two Russian cosmonauts venture outside the International Space Station on spacewalks Friday, Aug. 16, and Thursday, Aug. 22. NASA TV coverage will begin at 10 a.m. EDT both days.
