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...

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...

Dr. Tony Phillips, Science@NASA One day, years from now--or maybe billions of years, no one knows--aliens might be surprised to run across an old spaceship from Earth. Improbably far from home, the ancient probe is space cold, its nuclear power source spent long ago; an iconic white antenna points silently into the void, beaming no data to the species that made it. Yet this Voyager may speak to its finders. A golden record is fixed to the side of the probe, and if ET can decipher it, he...

NASA will hold a special Science Update at 1 p.m. EDT on Thursday, April 28, to discuss the unprecedented journey of NASA's twin Voyager spacecraft to the edge of our solar system. The event will be held in NASA headquarters' Webb auditorium at 300 E St. SW, in Washington. It will be broadcast live on NASA Television and streamed at: http://www.nasa.gov  After 33 years in space, the spacecraft still are operating and returning data from about 10 billion miles away from our sun. The...

SACRAMENTO, Calif., March 31, 2011 /PRNewswire-FirstCall/ -- Aerojet, a GenCorp (NYSE: GY) company, announced today that its thrusters on the Voyager 1 spacecraft assisted in several critical repositionings of the spacecraft over 10 billion miles away from the sun, at the edge of the solar system. On March 8, 2011, the 34-year-old Voyager 1 spacecraft did the deep space equivalent of a gymnastics routine at the Olympics as it rolled 70 degrees counterclockwise from its normal orientation...

NASA's Voyager spacecraft are hurtling towards the edge of our solar system, more than 10 billion miles away from our sun. Interstellar space - the medium between stars - is a region no human-made craft has ever been. On Apr. 28, 2011, a live NASA TV program will feature mission scientists discussing the distant areas Voyager 1 and 2 are exploring, 10 billion miles away from our sun. NASA is inviting classrooms to submit their single best question about the Voyager mission and interstellar...

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...

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...
