NASA to Attempt Historic Solar Sail Deployment

This summer, NASA engineers will try to realize a dream older than the Space Age itself: the deployment of a working solar sail in Earth orbit. The name of the device is NanoSail-D and it is scheduled for launch onboard a SpaceX Falcon 1 rocket as early as July 29, 2008.

Apollo Relic Reveals its Secrets

In 1967, Surveyor 3 landed on the Moon. Two years later, Apollo astronauts visited the little unmanned spacecraft and brought pieces of it home to Earth. Now, a portion of Surveyor's robotic arm, the scoop it used to sample moondust, is teaching researchers some long-lost secrets.

Strange Ring Found Circling Dead Star

NASA's Spitzer Space Telescope has found a bizarre ring of material around the magnetic remains of a star that blasted itself to smithereens. Although rings and spheres of material are common in the universe, this one is not like any ring astronomers have ever seen before.

Cartwheel Coronal Mass Ejection

Imagine a billion-ton cloud of gas launching itself off the surface of the sun and then ... doing a cartwheel. That's exactly what happened on April 9, 2008, when a coronal mass ejection or "CME" pirouetted over the sun's limb in full view of an international fleet of spacecraft.

Phoenix Lands on Mars

NASA's Phoenix spacecraft landed in the northern polar region of Mars Sunday to begin three months of examining a site chosen for its likelihood of having frozen water within reach of the lander's robotic arm.

Lunar GRAIL

Gravitationally speaking, the moon is a strange place. Satellites in lunar orbit feel odd, sideways tugs and end up nose down in the moondust. Astronauts standing in the middle of lunar lava seas weigh more than they do standing on the shore. A new NASA mission named GRAIL aims to map the moon's quirky gravity field and thus pave the way for future exploration.

A Super Solar Flare

In September 1859, a solar flare erupted so intense that the explosion itself was visible to the human eye. A ferocious geomagnetic storm ensued in which Northern Lights descended as far south as Cuba, the Bahamas and Hawaii. Meanwhile, telegraph engineers disconnected their batteries and powered communications by electricity from the auroras! Could it happen again?

Moondust and Duct Tape

Going to the Moon? Don't forget your duct tape. Thirty-six years ago when Apollo 17 astronauts found themselves a quarter million miles from home with a damaged moonbuggy, a roll of "good old fashioned American gray tape" saved the day.

Moondust in the Wind

Unlike Earth, the firmament of the moon is directly exposed to charged particles from the sun. What happens to moondust under the onslaught of solar wind? Researchers in a NASA-supported lab are finding some surprising answers.

Old Solar Cycle Returns

Three months ago, a new solar cycle began. This week, however, the sun surprised onlookers with three big sunspots from the previous solar cycle. Strangely enough, this is perfectly normal.
