NASA wants to mine asteroids

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.

If we landed on Europa, what would we want to know?

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.

NASA works on balloon-based telescope

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.

NASA says Sun's magnetic field is about to flip

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.

Absolutely mindblowing video shot from the Space Shuttle during launch

Drop whatever you're doing and watch this. NASA has released videos shot from onboard the Space Shuttle's Solid Rocket Boosters in the past, but you've never seen one prepared as masterfully as this. For one thing, the footage was shot in high definition, so the image is exceptionally clear.

NASA's Cassini identifies forces controlling Saturn moon jets

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.

NASA's Chandra sees eclipsing planet in X-rays for first time

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.

NASA awards $100,000 to initial analysis of 3D printing of biomaterials

NASA has selected 3D printing of biomaterials, such as arrays of cells, as one of the 12 proposals for study under Phase I of the NASA Innovative Advanced Concepts (NIAC) Program, which aims to turn science fiction into reality. 

Particle accelerator discovered in Earth’s Radiation Belts

Scientists have discovered a massive particle accelerator in the heart of one of the harshest regions of near-Earth space, a region of super-energetic, charged particles surrounding the globe called the Van Allen radiation belts.

Tropical ecosystems boost carbon dioxide as temperatures rise

NASA scientists and an international team of researchers have found tropical ecosystems can generate significant carbon dioxide when temperatures rise, unlike ecosystems in other parts of the world.

NASA's IRIS telescope offers first image of Sun's mysterious atmosphere

The moment when a telescope first opens its doors represents the culmination of years of work and planning - while simultaneously laying the groundwork for a wealth of research and answers yet to come. It is a moment of excitement and perhaps even a little uncertainty.

NASA satellites measure plant health

NASA scientists have established a new way to use satellites to measure what's occurring inside plants at a cellular level.

Spitzer telescope observes gas emission from Comet ISON

Astronomers using NASA's Spitzer Space Telescope have observed what most likely are strong carbon dioxide emissions from Comet ISON ahead of its anticipated pass through the inner solar system later this year.
