Jacks goods- -The Voyager 2 was only 448,600 miles away from Jupiter -Found volcanoes on jupiter’s moon, Io, the plumes from these volcanoes rose over 125 miles above the surface of the moon -nine of these volcanoes were found on Io which is half the size of the earth’s moon -given us reason to believe there is liquid water beneath the frozen surface of Europa -also the possibility that there are plate tectonics on [|Ganymede] (Satrun) -detected ultraviolet emissions from the upmost atmosphere -got a close look at the satellites around Saturn -found that 7% of the upper asmosphere is helium and the rest is hydrogen -Saturn is less dense than water - (Uranus) -tilted on its side to were the axis poles are pointed toward the sun -came 66,500miles from the planet’s center -ten moons were found in addition to the five already known -surrounded by rings, just like Saturn. The rings are made of particles the size of dust all the way to massive boulders -the moon Miranda shows indication of internal melting as well as upwelling of ice melting, probably from multiple collisions from meteors (Neptune) -took twelve years to get to Neptune -skimmed over the poles of Neptune by only 3000 miles -found six more moons -three more rings -found geysers of nitrogen on Triton, neptunes largest moon

Voyager 1 -launched September 5 1977 -today it is the farthest manmade object in space

The Voyagers were built by NASA's Jet Propulsion Laboratory in Pasadena, Calif., which continues to operate both spacecraft.**

 * __Jack has more info on Voyager 2. This is just some information of mine.__**

NASA’s Voyager 2 spacecraft has followed its twin, Voyager 1, into the solar systems final frontier Voyager 2 proves that solar system is squashed.
 * This is found by Voyager 2 crossing in the path of Voyager 1 and making a solar wind termination shock
 * This was almost 1.6 billion kilometers closer to the sun
 * It is confirmed that our solar system is "squashed" or "dented"

NASA's two existing Voyager spacecrafts are celebrating three decades of flight as they head toward interstellar space

__**Voyager 1:**__

  Voyager 1 made its closest approach to Jupiter on March 5, 1979, and Voyager 2 followed with its closest approach occur­ring on July 9, 1979.
 * Voyager 1 is the most distant human-made object in the universe
 * Long-lived nuclear batteries are expected to provide electrical power until 2020 when Voyager 1 will be more than 13 billion miles from Earth.
 * __**Operations**__
 * The Voyager mission was designed to take advantage of a rare geometric arrangement of the outer planets in the late 1970s and the 1980s.
 * Voyagers 1 and 2 are identical spacecraft. Each is equipped with instruments to conduct 10 different experiments. The instruments include television cameras, infrared and ultraviolet sensors, magnetometers, plasma detectors, and cosmic-ray and charged-particle sensors. In addition, the spacecraft radio is used to conduct experiments.
 * 
 * Voyager 1 is now leaving the solar system, rising above the ecliptic plane at an angle of about 35 degrees at a rate of about 520 million kilometers (about 320 million miles) a year.
