In which direction is the sun's stream of charged particles banking when it nears the edge of the solar system? The answer, scientists know, is blowing in the wind. It's just a matter of getting NASA's Voyager 1 spacecraft in the right orientation to detect it. To enable Voyager 1's Low Energy Charged Particle instrument to gather these data, the spacecraft performed a maneuver on March 7 that it hadn't done for 21 years, except in a preparatory test last month. At 9:10 a.m. PST (12:10 p.m....

What would our solar system look like if visitors from other worlds took a series of pictures? NASA's MESSENGER spacecraft did just that by piecing together the first portrait of our solar system from the inside looking out. Comprised of 34 images, the mosaic provides a complement to the solar system portrait--from the outside looking in--taken by Voyager 1 in 1990. "Obtaining this portrait was a terrific feat by the MESSENGER team," says MESSENGER principal investigator Sean Solomon, of the...

As NASA's Voyager 2 spacecraft made the only close approach to date of our mysterious seventh planet Uranus 25 years ago, Project Scientist Ed Stone and the Voyager team gathered at NASA's Jet Propulsion Laboratory, Pasadena, Calif., to pore over the data coming in. Images of the small, icy Uranus moon Miranda were particularly surprising. Since small moons tend to cool and freeze over rapidly after their formation, scientists had expected a boring, ancient surface, pockmarked by...

SACRAMENTO, Calif., Dec. 23, 2010 /PRNewswire-FirstCall/ -- Aerojet, a GenCorp (NYSE: GY) company, celebrates NASA's recent announcement that Voyager 1 has reached a point at the edge of our solar system where there is no outward motion of solar wind. Now approximately 10.8 billion miles from the sun, Voyager 1's passage through the heliosheath, the turbulent outer shell of the sun's sphere of influence, and the spacecraft's upcoming departure from our solar system, mark a major milestone...

PASADENA, Calif., Dec. 13, 2010 /PRNewswire-USNewswire/ -- The 33-year odyssey of NASA's Voyager 1 spacecraft has reached a distant point at the edge of our solar system where there is no outward motion of solar wind.

The 33-year odyssey of NASA's Voyager 1 spacecraft has reached a distant point at the edge of our solar system where there is no outward motion of solar wind. Now hurtling toward interstellar space some 10.8 billion miles from the sun, Voyager 1 has crossed into an area where the velocity of the hot ionized gas, or plasma, emanating directly outward from the sun has slowed to zero. Scientists suspect the solar wind has been turned sideways by the pressure from the interstellar wind in the...

Ed Stone, project scientist for NASA's Voyager mission, remembers the first time he saw the kinks in one of Saturn's narrowest rings. It was the day the Voyager 1 spacecraft made its closest approach to the giant ringed planet, 30 years ago. Scientists were gathering in front of television monitors and in one another's offices every day during this heady period to pore over the bewildering images and other data streaming down to NASA's Jet Propulsion Laboratory in Pasadena, Calif. Stone drew...

As NASA's two Voyager spacecraft hurtle towards the edge of our solar system, a new project manager will shepherd the spacecraft into this unexplored territory: Suzanne Dodd, whose first job at NASA's Jet Propulsion Laboratory in Pasadena, Calif., involved sequencing science and engineering commands for Voyager 1 and 2 in 1984."I'm thrilled to re-join a pioneering mission that set up adventures for so many other spacecraft to follow," Dodd said. "There will be more firsts to come as we gather...

When NASA launched the Interstellar Boundary Explorer (IBEX) on October 19, 2008, space physicists held their collective breath for never-before-seen views of a collision zone far beyond the planets, roughly 10 billion miles away. That's where the solar wind, an outward rush of charged particles and magnetic fields continuously spewed by the Sun, runs into the flow of particles and fields that permeates interstellar space in our neighborhood of the Milky Way galaxy. No spacecraft had ever...

NASA's plucky Voyager 2 spacecraft hit a long-haul operations milestone June 28 -- operating continuously for 12,000 days. For nearly 33 years, the venerable spacecraft has been returning data about the giant outer planets, and the characteristics and interaction of solar wind between and beyond the planets. Among its many findings, Voyager 2 discovered Neptune's Great Dark Spot and its 450-meter-per-second (1,000-mph) winds. The two Voyager spacecraft have been the longest continuously...

Saturn's moon Pan -- Pan, the innermost known satellite, was found from photographs taken by Voyager during its encounter with Saturn. It was discovered by Mark R. Showalter in 1990, 9 years after the Voyager encounter. Pan is located 133,583 kilometers from the center of Saturn and is within the Encke Gap of Saturn's A-ring. It acts as a shepherd and is responsible for keeping the Encke gap open. It has a diameter of 20 kilometers. ----- Discovered by: Mark R. Showalter;...
