The fears were soon quieted: the radiation doesn't reach Earth, though it can affect satellites and humans moving through the belts. Nevertheless, many mysteries about the belts -- now known as the Van Allen Radiation belts -- remain to this day.

The sun pumps the inside of the bubble full of solar particles that stream out to the edge until they collide with the material that fills the rest of the galaxy, at a complex boundary called the heliosheath. On the other side of the boundary, electrically charged particles from the galactic wind blow by, but rebound off the heliosheath, never to enter the solar system. Neutral particles, on the other hand, are a different story. They saunter across the boundary as if it weren't there, continuing on another 7.5 billion miles for 30 years until they get caught by the sun's gravity, and sling shot around the star.

Instead, researchers want to send a spacecraft to rendezvous with a comet, then fire a harpoon to rapidly acquire samples from specific locations with surgical precision while hovering above the target.

And right now there is a need for NASA and the United States to have reliable access to low Earth orbit from homegrown sources. So, NASA's Commercial Crew Program and a number of American-led private companies are working together on new and innovative plans to do just that.

Dawn has been orbiting Vesta since July 15, obtaining high-resolution images of its bumpy, cratered surface and making other scientific measurements.

The rocket burn was performed to keep the venerable comet hunter's options open for yet another exploration of a solar system small body.

The images of the moon, the first ever taken of Enceladus with Cassini's synthetic aperture radar, reveal new details of some of the grooves in the moon's south polar region and unexpected textures in the ice. These images, obtained on Nov. 6, 2011, are the highest-resolution images of this region obtained so far.

But is the human body up to the challenge? Scientists believe that Caenorhabditis elegans, a microscopic worm which has biologically similarities to human beings, could help us understand how humans might cope with long-duration space exploration.

Launched to space Nov. 19, 2010 as a payload on NASA's FASTSAT, a small satellite, NanoSail-D's sail deployed on Jan. 20. The flight phase of the mission successfully demonstrated a deorbit capability that could potentially be used to bring down decommissioned satellites and space debris by re-entering and totally burning up in Earth's atmosphere. The team continues to analyze the orbital data to determine how future satellites can use this new technology.

On Earth, a little water, maybe some chemicals, and the fire is smothered. In space, where there is no up or down, flames behave in unconventional ways. And when your entire world is the size of a five-bedroom home like the International Space Station, putting out even a small fire quickly is a life-and-death matter. Since March 2009, NASA's Flame Extinguishment Experiment, or FLEX, has conducted more than 200 tests to better understand the fundamentals of flames and how best to suppress fire in space. The investigation is currently ongoing aboard the space station.
