NASA's Voyager 1 Continues On Its Journey
2012-09-10 05:20:46

redOrbit Staff & Wire Reports - Your Universe Online The journey of NASA's Voyager 1 spacecraft towards interstellar space continued over the weekend, and officials with the US space agency continue to monitor the 35-year-old probe's progress as it grows ever closer to becoming the first man-made instrument to ever leave the solar system. As redOrbit.com's own Lawrence LeBlond reported last week, it is difficult to know when the vehicle, which is currently 11 billion miles from the...

Voyager 1 Celebrates 35th Anniversary, About To Cross Threshold Into Interstellar Space
2012-09-05 09:57:27

[WATCH VIDEO] Lawrence LeBlond for redOrbit.com - Your Universe Online Celebrating its 35th anniversary in space today, NASA´s Voyager 1 spacecraft is about to cross the threshold of our solar system, to boldly go where no man, nor machine, has ever gone before. While it is difficult to pinpoint the exact moment when the American space company´s premier long distance journeyer will cross the boundary of the heliosphere, expert measurements have indicated that it is very close....

Lee Rannals for redOrbit.com - Your Universe Online Monday marked the 35 year anniversary of NASA's Voyager 2 spacecraft launching from Earth, and embarking on a venture to go where no spacecraft has gone before. The Voyager 2 spacecraft, and its twin Voyager 1, are still hurtling through space, on a path that is sending them outside of our Solar System. "Even 35 years on, our rugged Voyager spacecraft are poised to make new discoveries as we eagerly await the signs that we've...

Voyager 1 Nearing Interstellar Space
2012-08-05 06:27:51

[ Watch the Video: Voyager 1 at the Final Frontier ] redOrbit Staff & Wire Reports - Your Universe Online The levels of high-energy cosmic rays originating from outside our solar system and the levels of lower-energy particles originating from within have been undergoing changes at a faster rate than at any other time in the past seven years, NASA officials announced on Friday. Citing data obtained from the Voyager 1 spacecraft, the US space agency revealed that there was a...

Voyager 1 Entering Interstellar Space
2012-06-15 13:52:45

Lee Rannals for redOrbit.com After several decades of making a lonely journey across our solar system, Voyager 1 has signaled to NASA that it may have reached the edge of interstellar space. The spacecraft, which launched in 1977, is now roughly 11 billion miles away and traveling at 6 miles per second. NASA said it takes Voyager 1's data 16 hours and 38 minutes to reach the antennas of its Deep Space Network on Earth. Data from the spacecraft indicates that the 34-year-old...

Auroras Seen Dancing Around On Uranus
2012-04-13 12:47:09

Scientists have seen auroras dancing around above the giant ice planet Uranus by using the Hubble Space Telescope. The Uranian light show consisted of short-lived, faint, glowing dots, a show completely different than that seen on planet Earth. The researchers detected the luminous spots twice on the dayside of Uranus, which is the side that is visible to Hubble. Unlike auroras on Earth, the newly detected auroras on Uranus appear to only last a couple of minutes. Auroras are a...

Ice Giants Found To Have More Water Volume
2012-03-20 03:06:13

The idea of compressing water is foreign to our daily experience. Nevertheless, an accurate estimate of water´s shrinking volume under the huge gravitational pressures of large planets is essential to astrophysicists trying to model the evolution of the universe. They need to assume how much space is taken up by water trapped under high density and pressure, deep inside a planet, to calculate how much is needed of other elements to flesh out the planet´s astronomical image. In...

Voyager Instrument Cooling After Heater Turned off
2012-01-18 12:59:22

In order to reduce power consumption, mission managers have turned off a heater on part of NASA's Voyager 1 spacecraft, dropping the temperature of its ultraviolet spectrometer instrument more than 23 degrees Celsius (41 degrees Fahrenheit). It is now operating at a temperature below minus 79 degrees Celsius (minus 110 degrees Fahrenheit), the coldest temperature that the instrument has ever endured. This heater shut-off is a step in the careful management of the diminishing electrical power...

NASA's Voyager Spacecraft Nears Edge Of The Solar System
2011-12-14 04:17:32

In 1977, Jimmy Carter was sworn in as president, Elvis died, Virginia park ranger Roy Sullivan was hit by lightning a record seventh time, and two NASA space probes destined to turn planetary science on its head launched from Cape Canaveral, Fla. The identical spacecraft, Voyager 1 and Voyager 2, were launched in the summer and programmed to pass by Jupiter and Saturn on different paths. Voyager 2 went on to visit Uranus and Neptune, completing the "Grand Tour of the Solar System," perhaps...

NASA's Voyager 1 spacecraft has entered a new region between our solar system and interstellar space. Data obtained from Voyager over the last year reveal this new region to be a kind of cosmic purgatory. In it, the wind of charged particles streaming out from our sun has calmed, our solar system's magnetic field has piled up, and higher-energy particles from inside our solar system appear to be leaking out into interstellar space. "Voyager tells us now that we're in a stagnation...

Planetary Ring -- A planetary ring is a ring of dust and other small particles orbiting around a planet in a flat disc-shaped region. The most spectacular and famous planetary rings are those around Saturn, but all four of the solar system's gas giant planets (Jupiter, Saturn, Uranus, Neptune) possess ring systems of their own. The origin of planetary rings is not precisely known, but they are thought to be unstable and dissipate over the course of tens or hundreds of millions of...

Planet Triton -- Triton is the planet Neptune's largest moon, discovered by William Lassell in 1846 just 17 days after the planet itself was discovered. It is named after Triton, from Greek mythology. Triton is unique among all large moons in the solar system for its retrograde orbit around the planet (i.e., it orbits in a direction opposite to the planet's rotation). Jupiter's moons Ananke, Carme, Pasiphae and Sinope and Saturn's moon Phoebe also orbit retrograde, but all of them...

Planet Larissa -- Larissa is the fifth of Neptune's known moons. It was discovered by Harold Reitsema based on ground-based stellar occultation observations, and was photographed by Voyager 2 in 1989. Larissa is irregular (non-spherical) in shape and appears to be heavily cratered, with no sign of any geological modification. Little else is known about it. Since its orbit is below Neptune's synchronous orbit radius it is slowly decaying due to tidal forces and will one day break up...

Planet Galatea -- Galatea is the fourth known moon of Neptune, named after the the Nereid of Greek legend. It was discovered in 1989 by Voyager 2 and very little is known about it. It is irregularly shaped and shows no sign of any geological modification. Since its orbit is below Neptune's synchronous orbit radius it is slowly decaying due to tidal forces and will one day break up into a planetary ring or impact on Neptune's surface. ----- Discovery Discovered by Voyager 2...
