What did Voyager 1 teach us?
The Voyager mission not only transformed our knowledge of Jupiter, Saturn and their dozens of moons, it also gave us our first close-up look at the strange and wondrous planets Uranus and Neptune. Voyager will be remembered as one of the greatest achievements in exploration.
What information does Voyager send back?
The Voyager spacecraft revealed the enormous amount of detail in the rings of Saturn, discovered the rings of Jupiter and provided the first detailed images of the rings of Uranus and Neptune. Voyager imaged Earth’s moon and discovered twenty-three new moons at the outer planets.
What was special about Voyagers 1 and 2?
Their two-planet mission became four. Their five-year lifetimes stretched to 12 and more. Eventually, between them, Voyager 1 and 2 would explore all the giant outer planets of our solar system, 48 of their moons, and the unique systems of rings and magnetic fields those planets possess.
What was the purpose of the Voyager record?
The Voyager Golden Records are two phonograph records that were included aboard both Voyager spacecraft launched in 1977. The records contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form who may find them.
How are the voyagers powered?
Voyager’s power supply comes from a radioisotope thermoelectric generator (RTG), which turns heat from the decay of a radioactive material into electricity to power the spacecraft. Due to the natural decay of the material inside the RTG, Voyager 2’s power budget goes down by about 4 watts per year.
How has the Voyager mission benefited society?
The Voyagers discovered many moons around the planets we never knew were there. And even the ones we knew were there were literally just points of light in telescopes before that. All of sudden they changed to geologic objects, to worlds that had weather and volcanoes and tectonics.
Are the Voyagers still transmitting?
But farther—much farther—Voyager 1, one of the oldest space probes and the most distant human-made object from Earth, is still doing science. But even as it drifts farther and farther from a dimming sun, it’s still sending information back to Earth, as scientists recently reported in The Astrophysical Journal.
What was unique about the gravity assist that Voyager used?
Voyager 2 is a good choice because it used gravity assists to visit all four of the outer planets: Jupiter, Saturn, Uranus and Neptune. The outer planets line up in such a fortuitous way about every 175 years, and it encourages the idea of using gravity assists repeatedly to direct the spacecraft to the next target.
Whose message is on the record that was flown with one of the Voyager spacecraft?
The items for the record, which is carried on both the Voyager 1 and Voyager 2 spacecraft, were selected for NASA by a committee chaired by Carl Sagan of Cornell University….Greetings.

What is the message on Voyager 1?
If one such civilization intercepts Voyager and can understand these recorded contents, here is our message: “This is a present from a small, distant world, a token of our sounds, our science, our images, our music, our thoughts and our feelings. We are attempting to survive our time so we may live into yours.
How does the Voyager communicate with Earth?
The radio communication system of Voyager 1 was designed to be used up to and beyond the limits of the Solar System. The communication system includes a 3.7-meter (12 ft) diameter high gain Cassegrain antenna to send and receive radio waves via the three Deep Space Network stations on the Earth.
How do they control Voyager?
Pellets of plutonium dioxide release heat through natural decay. This heat is converted into electricity using a series of thermocouples. Although the power output isn’t very strong, it powers the electronics and instruments on board the Voyagers for a very long time.
