NASA's Deep Space comet hunter mission comes to a close

After almost 9 years in space that included an unprecedented July 4th impact and subsequent flyby of a comet, an additional comet flyby, and the return of approximately 500,000 images of celestial objects, NASA's Deep Impact mission has ended.

NASA Curiosity Rover detects no methane on Mars

Data from NASA's Curiosity rover has revealed the Martian environment lacks methane. This is a surprise to researchers because previous data reported by U.S. and international scientists indicated positive detections. The roving laboratory performed extensive tests to search for traces of Martian methane.

NASA Dryden engineers capture dramatic supersonic shockwave images

Elusive schlieren images of supersonic shockwaves emanating from NASA F-15 and F/A-18 aircraft flying at supersonic speeds were captured during recent pilot proficiency flights.

NASA spacecraft embarks on historic journey into interstellar space

NASA's Voyager 1 spacecraft officially is the first human-made object to venture into interstellar space. The 36-year-old probe is about 12 billion miles (19 billion kilometers) from our sun. New and unexpected data indicate Voyager 1 has been traveling for about one year through plasma, or ionized gas, present in the space between stars.

Long drive puts NASA Mars Rover near planned waypoint

NASA's Mars rover Curiosity now has a view of a patch of exposed bedrock scientists selected for a few days of close-up study, the first such study since the rover began its long trek to Mount Sharp two months ago.

NEXT provides lasting propulsion and high speeds for deep space missions

Ion propulsion used to exist only in the imagination of science fiction writers. But after years of research and development NASA is poised to equip some of its most important deep space missions with ion engines that can nudge spacecraft using charged particles accelerated to blistering speeds of up to 90,000 miles per hour. And in the vastness of space, those engines need to push continuously for years.

NASA wants to build huge spacecraft in orbit with robots and 3D printers

If you want to send a large piece of a spacecraft into orbit that can later be assembled into a larger product in space, it is common practice to build it on Earth and design it to fold up so it can fit into a rocket.For the past ...

Catching black holes on the fly

NASA's black-hole-hunter spacecraft, the Nuclear Spectroscopic Telescope Array, or NuSTAR, has "bagged" its first 10 supermassive black holes. The mission, which has a mast the length of a school bus, is the first telescope capable of focusing the highest-energy X-ray light into detailed pictures.

NASA evaluates four candidate sites for 2016 Mars Mission

NASA has narrowed to four the number of potential landing sites for the agency's next mission to the surface of Mars, a 2016 lander to study the planet's interior. The stationary Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport (InSight) lander is scheduled to launch in March 2016 and land on Mars six months later.

NASA study eyes soot’s role in 1800s glacier retreat

A NASA-led team of scientists has uncovered strong evidence that soot from a rapidly industrializing Europe caused the abrupt retreat of mountain glaciers in the European Alps that began in the 1860s, a period often thought of as the end of the Little Ice Age. The research, published Sept. 3 in the Proceedings of the National Academy of Sciences, may help resolve a longstanding scientific debate.

NASA’s Hubble spots a cosmic caterpillar

This light-year-long knot of interstellar gas and dust resembles a caterpillar on its way to a feast. But the meat of the story is not only what this cosmic caterpillar eats for lunch, but also what's eating it. Harsh winds from extremely bright stars are blasting ultraviolet radiation at this "wanna-be" star and sculpting the gas and dust into its long shape.

NASA says Saturn moon may have rigid ice shell

An analysis of gravity and topography data from the Saturnian moon Titan obtained by NASA's Cassini spacecraft suggests there could be something unexpected about the moon's outer ice shell.

NASA's space laser to prove increased broadband possible

When NASA’s Lunar Laser Communication Demonstration (LLCD) begins operation aboard the Lunar Atmosphere and Dust Environment Explorer (LADEE) mission managed by NASA’s Ames Research Center in Moffett Field, Calif., it will attempt to show two-way laser communication beyond Earth is possible, expanding the possibility of transmitting huge amounts of data.

NASA tests limits of 3D printing with powerful rocket engine check

The largest 3-D printed rocket engine component NASA ever has tested blazed to life Thursday, Aug. 22 during an engine firing that generated a record 20,000 pounds of thrust.

NASA to crash test helicopter to study safety

Anybody who says NASA researchers don't know how to have a smashing good time has not met a team at NASA's Langley Research Center in Hampton, Va. They are test engineers whose job it is to make aircraft safer by crashing them.

NASA's Spitzer Telescope celebrates 10 years in space

Ten years after a Delta II rocket launched NASA's Spitzer Space Telescope, lighting up the night sky over Cape Canaveral, Fla., the fourth of the agency's four Great Observatories continues to illuminate the dark side of the cosmos with its infrared eyes.

NASA releases new asteroid mission images

NASA has released new photos and video animations depicting the agency's planned mission to find, capture, redirect, and study a near-Earth asteroid. The images depict crew operations including the Orion spacecraft's trip to and rendezvous with the relocated asteroid, as well as astronauts maneuvering through a spacewalk to collect samples from the asteroid.

NASA's Fermi celebrates 5 years in space, kicks off extended mission

During its five-year primary mission, NASA's Fermi Gamma-ray Space Telescope has given astronomers an increasingly detailed portrait of the universe's most extraordinary phenomena, from giant black holes in the hearts of distant galaxies to thunderstorms on Earth.

NASA's Cassini sees Earth waving at Saturn

People around the world shared more than 1,400 images of themselves as part of the Wave at Saturn event organized by NASA's Cassini mission on July 19 -- the day the Cassini spacecraft turned back toward Earth to take our picture. The mission has assembled a collage from those images which is available here. 

NASA recreates Earth’s northern lights

Scientists have harnessed the tools needed to stage Earth’s most colorful light show, and they have brought the Aurora Borealis into a lab at NASA’s Langley Research Center in Hampton, Va.
