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...

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

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...

NASA´s New Horizons mission reached a special milestone Friday, Dec. 2, 2011, on its way to reconnoiter the Pluto system, coming closer to Pluto than any other spacecraft. It´s taken New Horizons 2,143 days of high-speed flight — covering more than a million kilometers per day for nearly six years–to break the closest-approach mark of 1.58 billion kilometers set by NASA´s Voyager 1 in January 1986. “What a cool milestone!” says New Horizons...

Voyager 2 Switches To Backup Thruster Set
2011-11-15 04:28:36

NASA's Voyager 2 has successfully switched to the backup set of thrusters that controls the roll of the spacecraft. Deep Space Network personnel sent commands to the spacecraft to make the change on Nov. 4 and received confirmation on Monday, November 14 that the switch has been made. The change allows engineers to reduce the amount of power that the 34-year-old spacecraft needs to operate by turning off the heater that keeps the fuel to the primary thrusters warm. Although the rate of...

Voyager 2 Set To Switch To Backup Thruster Set
2011-11-07 10:11:55

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...

NASA said Wednesday that Voyager 1 could cross over into the frontier of interstellar space at any time and much earlier than previously thought. Data from Voyager's low-energy charged particle instrument have indicated that the outward speed of the charged particles streaming from the sun has slowed to zero. The stagnation of this solar wind has continued through at least February 2011, marking a thick, previously unpredicted "transition zone" at the edge of our solar system. "There is one...

Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...

Saturn's moon Pandora -- Pandora [pan-DOR-uh] is the fourth of Saturn's known satellites. It was discovered from photographs taken by Voyager during its encounter with Saturn by S. Collins and others. Pandora is the outer shepherd satellite for Saturn's F-ring. It has a diameter of about 114 by 84 by 62 kilometers (71 by 52 by 38 miles) and appears to be very heavily cratered. The two largest craters are about 30 kilometers (19 miles) in diameter. No linear valleys or ridges are...

Saturn's moon Prometheus -- Prometheus [pra-MEE-thee-us] is the third of Saturn's known satellites. It was discovered from photographs taken by Voyager during its encounter with Saturn by S. Collins and others. Prometheus acts as a shepherd satellite for the inner edge of Saturn's F Ring. The moon is extremely elongated about 145 by 85 by 62 kilometers (90 by 53 by 39 miles) in diameter. It has a number of ridges and valleys on its northern side. Several craters about 20...

Saturn's moon Atlas -- Atlas, the second of Saturn's known satellites, orbits near the outer edge of the A-ring and is about 40 by 20 kilometers (25 by 15 miles) in size. It is probably a shepherd satellite for Saturn's A-ring. Atlas was discovered by R. Terrile in 1980 from photographs taken by Voyager during its encounter with Saturn. ----- Discovered by: R. Terrile/Voyager 1 Date of Discovery: 1980 Distance from Saturn: 137,670 km Radius: 18.517.213.5 km Orbital...
