Atmospheric physicist Nick Gorkavyi missed witnessing an event of the century last winter when a meteor exploded over his hometown of Chelyabinsk, Russia. From Greenbelt, Md., however, NASA's Gorkavyi and colleagues witnessed a never-before-seen view of the atmospheric aftermath of the explosion.
Hours before the heat rose in the Mojave Desert of Southern California on Aug. 2 the Dream Chaser rolled out of a hangar at dawn as teams prepared to pull the flight vehicle through a series of 60 mph ground tow tests.
NASA's Mars Science Laboratory spacecraft inspired millions of people worldwide a year ago when its unprecedented "sky crane" landing system successfully landed the Curiosity rover in a crater on the red planet on Aug. 6, 2012 (Aug. 5, 2012, PDT).
NASA's Juno spacecraft is now halfway to Jupiter.
NASA's Mars Reconnaissance Orbiter is switching from one motion-sensing device to a duplicate unit onboard.
Over the last hundred years, the human population has exploded from about 1.5 billion to more than seven billion, driving an ever-increasing demand for resources. To satisfy civilization's appetite, communities have expanded recycling efforts while mine operators must explore forbidding frontiers to seek out new deposits, opening mines miles underground or even at the bottom of the ocean.
Heliophysics nuggets are a collection of early science results, new research techniques, and instrument updates that further our attempt to understand the sun and the dynamic space weather system that surrounds Earth.
Most of what scientists know of Jupiter's moon Europa they have gleaned from a dozen or so close flybys from NASA's Voyager 2 spacecraft in 1979 and NASA's Galileo spacecraft in the mid-to-late 1990s.
Dr. Rinehart is hoping to change the way scientists study the stars. To do this he needs a group of interns…and one very large balloon.
Something big is about to happen on the sun. According to measurements from NASA-supported observatories, the sun's vast magnetic field is about to flip.
Geologists from Brown University have developed a promising new explanation for a mysterious type of crater on the surface on Mars.
Using infrared data from the Subaru Telescope in Hawaii, an international team of astronomers has imaged a giant planet around the bright star GJ 504. Several times the mass of Jupiter and similar in size, the new world, dubbed GJ 504b, is the lowest-mass planet ever detected around a star like the sun using direct imaging techniques.
Marvel Comic's fictional superhero, Ironman, uses a powered armor suit that allows him superhuman strength. While NASA's X1 robotic exoskeleton can't do what you see in the movies, the latest robotic, space technology, spinoff derived from NASA's Robonaut 2 project may someday help astronauts stay healthier in space with the added benefit of assisting paraplegics in walking here on Earth.
NASA's Curiosity rover will mark one year on Mars next week and has already achieved its main science goal of revealing ancient Mars could have supported life. The mobile laboratory also is guiding designs for future planetary missions.
Craters once brim-full with sediments and water have long since drained dry, but traces of their former lives as muddy lakes cling on in the Martian desert.
Our universe is filled with gobs of galaxies, bound together by gravity into larger families called clusters. Lying at the heart of most clusters is a monster galaxy thought to grow in size by merging with neighboring galaxies, a process astronomers call galactic cannibalism.
Astronomers using NASA's Spitzer Space Telescope have spotted a young stellar system that "blinks" every 93 days. Called YLW 16A, the system likely consists of three developing stars, two of which are surrounded by a disk of material left over from the star-formation process.
The intensity of the jets of water ice and organic particles that shoot out from Saturn's moon Enceladus depends on the moon's proximity to the ringed planet, according to data obtained by NASA's Cassini spacecraft.
An advanced laser system offering vastly faster data speeds is now ready for linking with spacecraft beyond our planet following a series of crucial ground tests. Later this year, ESA’s observatory in Spain will use the laser to communicate with a NASA Moon orbiter.
For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exoplanet passing in front of its parent star.
