Behold, directly overhead, a certain strange star was suddenly seen...
Amazed, and as if astonished and stupefied, I stood still.

Laboratory Director Tawnya Plummer Laughinghouse

Wed, 01/08/2025 - 2:07pm
"As a young college student, it was the first time I ever faced [this situation], and it buckled me. It set me back until I realized that I could do it and that my worth wasn't based on what someone else thought of me or my abilities…If I had pulled myself out of that STEM major, I would never have been managing a technology demonstration program for NASA that launched ten technologies into space.” – Tawnya Plummer Laughinghouse, Director of the Materials and Processes Laboratory, Engineering Directorate, NASA’s Marshall Space Flight Center

Hubble Spies a Cosmic Eye

Fri, 12/27/2024 - 11:27am
This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 2566, which sits 76 million light-years away in the constellation Puppis. A prominent bar of stars stretches across the center of this galaxy, and spiral arms emerge from each end of the bar. Because NGC 2566 appears tilted from our perspective, its disk takes on an almond shape, giving the galaxy the appearance of a cosmic eye.

NASA Runs X-59 Engine in Maximum Afterburner

Thu, 12/26/2024 - 11:55am
NASA’s X-59 quiet supersonic research aircraft completed its first maximum afterburner test at Lockheed Martin’s Skunk Works facility in Palmdale, California. This full-power test, during which the engine generates additional thrust, validates the additional power needed for meeting the testing conditions of the aircraft. The X-59 is the centerpiece of NASA’s Quesst mission, which aims to overcome a major barrier to supersonic flight over land by reducing the noise of sonic booms.
