The second year of an unprecedented balloon campaign in Antarctica has just begun. The NASA-funded mission – called the Balloon Array for Radiation belt Relativistic Electron Losses, or BARREL – is led by Dartmouth College in Hanover, N.H. The mission is unique, as it relies not on one gigantic balloon, but on many smaller ones, 20 in total.
China's Chang'e 3 landed on Mare Imbrium (Sea of Rains) just east of a 450 m diameter impact crater on 14 December 2013. Soon after landing, a small rover named Yutu (or Jade Rabbit in English) was deployed and took its first tentative drive onto the airless regolith.
Environmental research and weather forecasting are about to get a significant technology boost as NASA and the Japan Aerospace Exploration Agency (JAXA) prepare to launch a new satellite in February.
A NASA observatory that will make the most precise, highest-resolution and most complete, space-based measurements of carbon dioxide in Earth's atmosphere to date has marked a key milestone in preparation for its planned July 2014 launch.
The photo known as Earthrise is the first color photograph of Earth taken by a person in lunar orbit. Earthrise is the cover photo of TIME's Great Images of the 20th Century, and is the central photo on the cover of LIFE's 100 Photographs That Changed the World.q
NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE), a spacecraft that made the most comprehensive survey to date of asteroids and comets, has returned its first set of test images in preparation for a renewed mission.
In the fable of the town and country mice, the country mouse visits his city-dwelling cousin to discover a world of opulence. In the early cosmos, billions of years ago, galaxies resided in the equivalent of urban or country environments.
A giant crane will tower above NASA's Jet Propulsion Laboratory in Pasadena, Calif., shooting out of a hilly mesa like an oversized erector set, ready to help test components of NASA's Low Density Supersonic Decelerator (LDSD) project.
Telescopes help distant objects appear bigger, but this is only one of their advantages. Telescopes can also collect light in ranges that our eyes alone cannot see, providing scientists ways of observing a whole host of material and processes that would otherwise be inaccessible.
NASA completed a series of high-tech can-crushing tests last week as an enormous fuel tank crumbled under the pressure of almost a million pounds of force, all in the name of building lighter, more affordable rockets.
NASA's Cassini spacecraft is providing scientists with key clues about Saturn's moon Titan, and in particular, its hydrocarbon lakes and seas. Titan is one of the most Earth-like places in the solar system, and the only place other than our planet that has stable liquid on its surface.
NASA scientists have revealed the inner workings of the ozone hole that forms annually over Antarctica and found that declining chlorine in the stratosphere has not yet caused a recovery of the ozone hole.
NASA's Johnson Space Center has been hard at work preparing for the DARPA Robotics Challeng. The results are pretty cool. NASA sees robots taking over the world once they get self-aware doing NASA's dirty work on Mars. That's the way we read it. Behold Valkyrie, superhero robot. She will be our queen, soon.
When NASA’s Juno spacecraft flew past Earth on Oct. 9, 2013, it received a boost in speed of more than 8,800 mph (about 7.3 kilometer per second), which set it on course for a July 4, 2016, rendezvous with Jupiter, the largest planet in our solar system.
NASA's Mars Reconnaissance Orbiter has revealed to scientists slender dark markings -- possibly due to salty water – that advance seasonally down slopes surprisingly close to the Martian equator.
NASA's visualization (video) below shows the position of the sun's magnetic fields from January 1997 to December 2013.
NASA's Curiosity Mars rover has passed the milestone of 100,000 shots fired by its laser. It uses the laser as one way to check which chemical elements are in rocks and soils.
A new study using observations from a novel instrument provides the best look to date at magnetic fields at the heart of gamma-ray bursts, the most energetic explosions in the universe. An international team of astronomers from Britain, Slovenia and Italy has glimpsed the infrastructure of a burst's high-speed jet.
Black holes can be petite, with masses only about 10 times that of our sun -- or monstrous, boasting the equivalent in mass up to 10 billion suns. Do black holes also come in size medium? NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, is busy scrutinizing a class of black holes that may fall into the proposed medium-sized category.
High-resolution global atmospheric modeling provides a unique tool to study the role of weather within Earth’s climate system. NASA’s Goddard Earth Observing System Model (GEOS-5) is capable of simulating worldwide weather at resolutions as fine as 3.5 kilometers.
