A spacecraft from Earth has left its cosmic backyard and taken its first steps in interstellar space. After streaking through space for nearly 35 years, NASA's robotic Voyager 1 probe finally left the solar system in August 2012, a study published today (Sept. 12) in the journal Science reports. "Voyager has boldly gone where no probe has gone before, marking one of the most significant technological achievements in the annals of the history of science, and as it enters interstellar space, it adds a new chapter in human scientific dreams and endeavors," NASA science chief John Grunsfeld said in...

WASHINGTON – Thirty-five years after its launch, Voyager 1 appears to have travelled beyond the influence of the Sun and exited the heliosphere, according to a new study appearing online today. The heliosphere is a region of space dominated by the Sun and its wind of energetic particles, and which is thought to be enclosed, bubble-like, in the surrounding interstellar medium of gas and dust that pervades the Milky Way galaxy. On August 25, 2012, NASA's Voyager 1 spacecraft measured drastic changes in radiation levels, more than 11 billion miles from the Sun. Anomalous cosmic rays, which are cosmic rays...

Explanation: On another Valentine's Day (February 14, 1990), cruising four billion miles from the Sun, the Voyager 1 spacecraft looked back to make this first ever family portrait of our Solar System. The complete portrait is a 60 frame mosaic made from a vantage point 32 degrees above the ecliptic plane. In it, Voyager's wide angle camera frames sweep through the inner Solar System at the left, linking up with gas giant Neptune, at the time the Solar System's outermost planet, at the far right. Positions for Venus, Earth, Jupiter, Saturn, Uranus, and Neptune are indicated by letters, while the...

An artist's concept of NASA's Voyager spacecraft, which is now about 11 billion miles from the sun, NASA said. (CNN) -- Are we there yet? If you're Voyager 1 and you're looking for a spot beyond the end of our solar system, the answer is no. NASA officials have been saying for months that Voyager 1 is almost there when it comes to interstellar space as it continues the longest road trip in the history of mankind. Voyager 1 and Voyager 2 took off 16 days apart in 1977, and Voyager 1 is now about 11 billion miles (18 billion...

"35 years after its launch, Voyager 1 is poised to 'leave' the bubble of the solar system and sail into the mystery of interstellar space"

ast week, in the corners of the Internet devoted to outer space, things started to get a little, well, hot. Voyager 1, the man-made object farthest away from Earth, was encountering a sharp uptick in the number of a certain kind of energetic particles around it. Had the spacecraft become the first human creation to "officially" leave the solar system? It's hard to overstate how wild an accomplishment this would be: A machine, built here on Earth by the brain- and handiwork of humans, has sailed from Florida, out of Earth's orbit, beyond Mars, beyond the gas giants of Jupiter...

NASA's Deep Space Network personnel sent commands to the Voyager 2 spacecraft Nov. 4 to switch to the backup set of thrusters that controls the roll of the spacecraft. Confirmation was received today that the spacecraft accepted the commands. The change will allow the 34-year-old spacecraft to reduce the amount of power it requires to operate and use previously unused thrusters as it continues its journey toward interstellar space, beyond our solar system. Launched in 1977, Voyager 1 and Voyager 2 are each equipped with six sets, or pairs, of thrusters to control their movement. These include three pairs of...

(PhysOrg.com) -- 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 crater-upon-weathered-crater. Instead they saw grooved terrain with linear valleys and ridges cutting through the older terrain and sometimes coming together in...

Voyager 1, the most distant spacecraft from Earth, has reached a new milestone in its quest to leave the Solar System. Now 17.4bn km (10.8bn miles) from home, the veteran probe has detected a distinct change in the flow of particles that surround it. These particles, which emanate from the Sun, are no longer travelling outwards but are moving sideways. It means Voyager must be very close to making the jump to interstellar space - the space between the stars. Edward Stone, the Voyager project scientist, lauded the explorer and the fascinating science it continues to return 33 years after...

Washington - NASA's Voyager 1 spacecraft has reached the outer edge of the solar system where wind from the Sun is no longer blowing outward, but sideways, the US space agency said. The spacecraft was launched in 1977 and has since snapped images of Earth and other planets in the solar system and provided NASA with crucial information as it makes its long journey into outer space. NASA researchers think Voyager 1 will leave the solar system and enter interstellar space, or the area in between the end of the Sun's influence and the next star system, in about four

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 unique data once the spacecraft reach interstellar space. There isn't a single mission currently on the books that will...

This July 4th, U.S. citizens around the world may proudly display American flags to celebrate Independence Day while away from home, but they won't hold a candle to the farthest American flag in history, which is leaving the entire solar system behind on NASA's Voyager 1 spacecraft. The spaceflying American flag is a not a huge version of Old Glory, but will be the only one flying more than 10.5 billion miles (16.9 billion km) from Earth this Fourth of July. It is riding on Voyager 1, a 33-year-old space probe on the outskirts of our solar system. Another...

NASA's plucky Voyager 2 spacecraft has hit a long-haul operations milestone - 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 operating spacecraft in deep space. Voyager 2 launched on August 20, 1977, when Jimmy Carter was president. Voyager 1 launched about two weeks later on Sept. 5. The two...

The solar system is passing through an interstellar cloud that physics says should not exist. In the Dec. 24th issue of Nature, a team of scientists reveal how NASA's Voyager spacecraft have solved the mystery. "Using data from Voyager, we have discovered a strong magnetic field just outside the solar system," explains lead author Merav Opher, a NASA Heliophysics Guest Investigator from George Mason University. "This magnetic field holds the interstellar cloud together and solves the long-standing puzzle of how it can exist at all." The discovery has implications for the future when the solar system will eventually bump...

(WBBM) -- Could it be the voice of E.T.? NASA scientists are puzzling over an abrupt change in what they're hearing from Voyager 2, the space probe launched more than 30 years ago. It's traveled more than 8 billion miles toward the edge of the solar system. Chief scientist Ed Stone says Voyager has suddenly begun sending back data NASA computers can't decipher. Here's what it sounds like CLICK HERE Scientists think it's a simple glitch in the computer. UFO buffs are hoping it could be a signal from life on planets far away. NASA will keep listening. Voyager was...

WASHINGTON — A Washington watchdog has filed a complaint against Louisiana Democratic Sen. Mary Landrieu, suggesting she may have traded her influence on a specific earmark for $30,000 in campaign contributions. Citizens for Responsibility and Ethics in Washington on Tuesday demanded the U.S. Department of Justice and U.S. district courts in Louisiana and Texas investigate whether Landrieu, who is in her second term, broke federal law back in 2001 by including a $2 million earmark in the District of Columbia appropriations bill for a company whose lobbyists had thrown her a fundraiser just days earlier. That event, held four days...
