It may not reach interstellar space for another 30 years.
It is headed in a broadly similar direction as Voyager 2, but having launched in 2006, it's many years behind. The fifth probe that will exit our solar system is New Horizons, the spacecraft that flew by Pluto in 2015. NASA faced a backlash for the nudity of the human figures. Like the Golden Record, the plaque features the pulsar map, uses hydrogen to define the binary units, and depicts humankind. They too, carry a message for extraterrestrial life, in the form of a 6-by-9-inch gold-anodized aluminum plaque, designed by Sagan and other members of the team that would go on to create the Voyager Golden Record five years later. They aren't traveling as fast as the Voyagers, but they will eventually enter interstellar space as well. NASA launched Pioneer 10 and 11 in 19, and has since lost communication with both. There are three other spacecraft headed toward interstellar space two of them, Pioneer 10 and Pioneer 11, are shown in this somewhat dated illustration: (Or, more accurately, stars will pass by them). In more than 40,000 years, they will each pass closer to another star than they are to our sun. It's moving southward relative to Earth's orbit, while Voyager 1 is moving northward. Voyager 2 is currently traveling through the outer layers of the heliosphere. That's how NASA knew that Voyager 1 became the first ever spacecraft to enter interstellar space in 2012: The probe detected high-density plasma characteristic of the space beyond the heliosphere (the bubble of solar wind created by the sun). Incredibly, Voyager 1 and Voyager 2 are still communicating with Earth - they aren't expected to lose power until the 2020s. Stumped? Hover over or click on the yellow circles for the intended meaning of these interstellar brain teasers: Put yourself in an extraterrestrial's shoes and try to guess what the etchings seek to communicate.
THE STAURN GOLDEN RECORDS HOW TO
Etched on the cover of that case are symbols explaining how to decode the record. The records are mounted on the outside of Voyager 1 and Voyager 2 and protected by an aluminum case. How would aliens know what to do with the Golden Record? Sagan's committee chose a copper phonograph LP as their medium, and over the course of six weeks they produced the "Golden Record": a collection of sounds and images that will probably outlast all human artifacts on Earth. The Voyager team tapped famous astronomer and science popularizer Carl Sagan to compose that message. Since they will orbit the Milky Way for the foreseeable future, the Voyagers should carry a message from their maker, NASA scientists decided.
With an 8-track tape memory system and onboard computers that are thousands of times weaker than the phone in your pocket, the two spacecraft sent back an immense amount of imagery and information about the four gas giants, Jupiter, Saturn, Uranus, and Neptune.īut NASA knew that after the planetary tour was complete, the Voyagers would remain on a trajectory toward interstellar space, having gained enough velocity from Jupiter's gravity to eventually escape the grasp of the sun. When Voyager 1 and Voyager 2 launched into space in 1977, their mission was to explore the outer solar system, and over the following decade, they did so admirably.
