Like the HAL computer aboard the ship Discovery from the famous science fiction story 2001: A Space Odyssey, each Voyager is equipped with computer programming for autonomous fault protection. The tape head should not begin to wear out until the tape has been moved back and forth through a distance comparable to that across the United States. The rings of Saturn appeared to the Voyagers as a dazzling necklace of 10,000 strands. The Milky Way could have dozens of alien civilizations capable of contacting us, If life exists on Titan, it’s even weirder than we thought, The sustainable voyager’s guide to the galaxy, A hundred stars have disappeared—and researchers aren’t ruling out aliens, Here’s how life could thrive on a planet orbiting a black hole—and other alternative suns.
This is equivalent to one-third the amount of effort estimated to complete the great pyramid at Giza to King Cheops. 17.46 km/s (Voyager 1) 16.08 km/s (Voyager 2) Voyager Mission Operations Status Report: Range, Velocity and Round Trip Light Time. A thumb-sized motor in the gear train drive assembly (which turns 9000 revolutions for each single revolution of the scan platform) will have rotated five million revolutions from launch through the Neptune encounter. It must come as no surprise that there are many remarkable, "gee-whiz" facts associated with the various aspects of the Voyager mission. As Voyager 2 streaked by Neptune and coasts out of the solar system, this fuel economy just got better and better! But there is a more definitive and unambiguous frontier, which the Voyagers will approach and pass through. Plasma wave investigation. The Voyager mission was officially approved in May 1972. Imagine playing a two-hour video cassette on your home VCR once a day for the next 33 years, without a failure. When space entered the realm of scientific inquiry, many wondered if the eternal mystique of the moon would survive. To some scientists, Titan, with its principally nitrogen atmosphere, seemed like a small Earth whose evolution had long ago been halted by the arrival of its ice age, perhaps deep-freezing a few organic relics beneath its present surface.
One computer memory alone contains over one million equivalent electronic parts, with each spacecraft containing some five million equivalent parts. The Voyager system is one of the most sophisticated ever designed for a deep-space probe. Pioneers 10 and 11 preceded Voyager in outstripping the gravitational attraction of the Sun but on February 17, 1998, Voyager 1 passed Pioneer 10 to become the most distant human-made object in space.

3. This is comparable to bowling strike-after-strike ad infinitum, assuming that you must hit within one inch of the strike pocket every time. They are: 1. Five instruments onboard the Voyagers directly support the five science investigations.
Closest approach to Saturn occurred on November 12, 1980 for Voyager 1; August 25, 1981 for Voyager 2.
The total cost of the Voyager mission from May 1972 through the Neptune encounter (including launch vehicles, radioactive power source (RTGs), and DSN tracking support) is 865 million dollars. The smooth water-ice surface of Jupiter's moon Europa may hide an ocean beneath, but some scientists believe any past oceans have turned to slush or ice. Its twin, Voyager 1, crossed this boundary in 2012, but Voyager 2 carries a working instrument that will provide first-of-its-kind observations of the nature of this gateway into interstellar space. The tape recorder aboard each Voyager has been designed to record and playback a great deal of scientific data. Ultraviolet spectrometer subsystem (UVS), Voyager 1 only.
Plasma instrument (PLS) Were it not for these dwindling consumables and the possibility of losing lock on the faint Sun, our tracking antennas could continue to "talk" with the Voyagers for another century or two! Voyager's fuel efficiency (in terms of mpg) is quite impressive. Barring any serious spacecraft subsystem failures, the Voyagers may survive until the early twenty-first century (~ 2025), when diminishing power and hydrazine levels will prevent further operation. Through the dedicated efforts of many skilled personnel for over three decades, the Voyagers have returned knowledge about the outer planets that had not existed in all of the preceding history of astronomy and planetary science. So, in a sense, one could consider the heliopause as the final frontier. 5. Many of these parts have a large number of "equivalent" smaller parts such as transistors. 4. The antennas must capture Voyager information from a signal so weak that the power striking the antenna is only 10 exponent -16 watts (1 part in 10 quadrillion). Dr. Sagan and his associates assembled 115 images and a variety of natural sounds. Closest approach to Neptune occurred on August 25, 1989 by Voyager 2. The celestial coordinates, magnitude, distances and speed are updated in real time and are computed using high quality data sets provided by the JPL Horizons ephemeris service (see acknowledgements for details). That heliosphere is the region influenced by the dynamic properties of the sun that are carried in the solar wind--such as magnetic fields, energetic particles and solar wind plasma. On September 5, Voyager 1 launched, also from Cape Canaveral aboard a Titan-Centaur rocket. Voyager 2, which is headed away from the sun beneath the plane of the planets, reached interstellar space on Nov. 5, 2018.
Spacecraft engineers devised ways to make Voyager 30 times steadier than the hour hand on a clock. 3. A total of 11,000 workyears was devoted to the Voyager project through the Neptune encounter. After the boom telescoped and rotated out of the cannister to an extension of nearly 13 meters (43 feet), the orientations of the magnetometer sensors were controlled to an accuracy better than two degrees. An experiment hinted at Martian life in the '70s. These tidbits have been summarized below in appropriate categories. Cosmic ray instrument (CRS)
Voyager 2 is escaping the solar system at a speed of about 3.3 AU per year. The military wants one-hour global delivery. In the absence of friction, on a level road, it would take nearly six hours to accelerate a large car up to a speed of 48 km/h (30 mph) using one of the thrusters. SpaceX thinks it can pull it off. Magnetic field instrument (MAG) Voyager 1 is currently over 7 billion miles (about 11 billion kilometers) away from Earth and is still transmitting -- it takes about 10 hours for the signal to travel from the spacecraft to Earth! Low energy charged particle investigation This is equivalent to the number of automobile crankshaft revolutions during a trip of 2725 km (1700 mi), about the distance from Boston,MA to Dallas,TX. So why did we stop looking?
Reproduction in whole or in part without permission is prohibited. Each spacecraft is so steady that angular rates are typically 15 times slower than the motion of a clock's hour hand. The message is carried by a phonograph record - -a 12-inch gold-plated copper disk containing sounds and images selected to portray the diversity of life and culture on Earth. The resolution of the Voyager narrow-angle television cameras is sharp enough to read a newspaper headline at a distance of 1 km (0.62 mi). Copyright © 2020 Popular Science. The spacecraft can place itself in a safe state in a matter of only seconds or minutes, an ability that is critical for its survival when round-trip communication times for Earth stretch to several hours as the spacecraft journeys to the remote outer solar system.
Voyager 1 is escaping the solar system at a speed of about 3.6 AU per year. "The Voyager 1 spacecraft is departing the solar system at a speed of 17.46 km/s …. 2. A modern-day electronic digital watch operates at a power level 20 billion times greater than this feeble level.
The Voyager spacecraft are the third and fourth human spacecraft to fly beyond all the planets in our solar system. Several may seem difficult to believe, but they are all true and accurate. Between them, Voyager 1 and 2 explored all the giant planets of our outer solar system, Jupiter, Saturn, Uranus and Neptune; 48 of their moons; and the unique system of rings and magnetic fields those planets possess. When Voyager 1 crosses the solar wind termination shock, it will have entered into the heliosheath, the turbulent region leading up to the heliopause. Because rockets are much, much faster than planes. Earth helped. Voyager 1 is escaping the solar system at a speed of about 3.6 AU per year. They are: 1. It is important to realize that: A total of five trillion bits of scientific data had been returned to Earth by both Voyager spacecraft at the completion of the Neptune encounter.
There are currently five science investigation teams participating in the Interstellar Mission. Both spacecraft are now exploring the Heliosheath.
The Sun's apparent motion in our sky moves over 40 times that amount in just one second. Even though most of the launch vehicle's 700 ton weight is due to rocket fuel, Voyager 2's great travel distance of 7.1 billion km (4.4 billion mi) from launch to Neptune resultsed in a fuel economy of about 13,000 km per liter (30,000 mi per gallon). The Voyager spacecraft use 23-watt radios. The Voyager gyroscopes can detect spacecraft angular motion as little as one ten-thousandth of a degree. The Voyager delivery accuracy at Neptune of 100 km (62 mi), divided by the trip distance or arc length traveled of 7,128,603,456 km (4,429,508,700 mi), is equivalent to the feat of sinking a 3630 km (2260 mi) golf putt, assuming that the golfer can make a few illegal fine adjustments while the ball is rolling across this incredibly long green.
