SUNSET: 
Chandrayaan 1 in Lunar Orbit
So far, so good for India's first attempt to explore the Moon. Chandrayaan 1 is safely in lunar orbit after a two-week series of rocket burns.
Amazing Close-ups of Enceladus
Ever wonder what it'd be like to view the icy terrain of Saturn's enigmatically active moon as if you were just 12 miles above it? Now you can, thanks to Cassini's close brush with Enceladus on Halloween.
Mercury Gets a Second Look
When NASA's Messenger spacecraft flew past the innermost planet on October 6th, it mapped another 30% of the surface never before viewed by spacecraft and gave scientists tantalizing hints of what Mercury is all about.
Hubble Returns to Work
After a month-long hiatus caused by an electronics failure, the Hubble Space Telescope has resumed its observations of the cosmos. But a final house call by Space Shuttle astronauts will have to wait until NASA engineers can round up some spare parts.
India's First Moon Shot
There's a new player in deep-space exploration, as India launches a highly instrumented spacecraft destined for lunar orbit.
NASA Satellite Spots New Type of Pulsar
The Fermi Gamma-ray Space Telescope has made its first major discovery.
Giant "Hurricanes" Ring Saturn's Poles
NASA scientists are scratching their heads over the monstrously large swirls revealed by the Cassini orbiter at the planet's top and bottom.
A Deep (Impact) Mystery
Deep Impact's in-your-face encounter with Comet Tempel 1 on July 4, 2005, created an enormous splash of dust and gas far more massive than anyone predicted. Some 3½ years later, planetary scientists are still struggling to understand what happened.
The New Face of Mercury
NASA's Messenger spacecraft slipped past the innermost planet on October 6th, revealing an amazing Mercurian landscape never before seen at close range.
Hubble Shuts Down, Repairs Delayed
With a Space Shuttle poised and ready in Florida to begin the fifth and final Hubble house call, the venerable orbiting observatory has had a malfunction that will probably delay the repair mission until early next year.
Opportunity's Mad Dash
After spending 4½ years doing geologists' bidding on Mars, you'd think that NASA would give its rovers a rest. Instead, one of them has started rolling toward a large crater that it likely won't reach for two years.
Rosetta's "Jewel in the Sky"
European scientists are excitedly poring over results from the Rosetta spacecraft's close flyby of asteroid Steins, even though an unexpected camera glitch cost them the best views of its cratered surface.
Phoenix Surpasses 90-day Milestone
NASA's newest lander has now been scratching, digging, sniffing, baking and tasting samples of Martian polar terrain for more than three months. How long can it survive in the fast-approaching winter — and how much more can it learn?
NASA Space Observatory Gets New Name
The best-ever gamma-ray satellite is living up to expectations and NASA has just given it a new name.
New Enceladus Closeups Now Arriving
The Cassini spacecraft is returning the data from Monday's close flyby of icy Enceladus, and NASA is putting up the first raw images.
Titan Makes a Splash
It's not covered by a global ocean, as theorists once thought. But Saturn's big moon does sport pools of liquid ethane big enough to float anyone's boat.
NASA Turns 50: Take a Photo!
The U.S. space agency was founded 50 years ago today. You can celebrate by finding your favorite NASA photograph.
An Electrifying Whodunit
Thanks to a quintet of identical spacecraft, space physicists have settled a decades-old debate over what triggers violent electromagnetic substorms inside Earth's magnetosphere.
Earth and Moon Dance for a Far Camera
From more than 30 million miles away, a NASA spacecraft snapped away as the Moon made a graceful pass in front of Earth's colorful disk.
Mars's Ancient Water Works
New observations from a NASA orbiter reveal that water and rock freely mingled across (or under) much of the Red Planet's surface.
