Voyager 1 is 16 billion miles from Earth, still transmitting data. Its power source has been running for 48 years. Voyager is kept alive by a single isotope. 4.5 kilograms of plutonium-238 sits inside a thermoelectric generator. As the isotope decays, it produces heat. 312 silicon-germanium thermocouples convert that heat into electricity. The generator has no moving parts. Hot side at 1,000°C, cold side at 300°C. 470 watts at launch from that temperature gap. The generator is 93.5% inefficient. That inefficiency is what keeps the spacecraft from freezing at -270°C. Power has decayed from 470 watts to 220 since launch. Engineers have shut down 8 of its 10 instruments to squeeze a few more years of data out of interstellar space. Starting in the 1970s over 2,000 plutonium-powered pacemakers went into human chests. Now researchers are replacing plutonium with carbon-14 in synthetic diamond. Carbon-14 only emits beta radiation and the diamond blocks all of it. A 5,700-year battery safe enough to hold in your hand.

The Voyager 1 space probe is the furthest man-made object from Earth, at over 14.8 billion miles (23.8 billion km). #FACT

That's why, as Rave FM, we invited the Cosmic DJ Aliena, who composed a set for us after receiving a signal from Voyager 1 👽 You’ll hear it on our radio station on December 14th.

#NASA #Voyager1 Launched Mon, 05 Sept 1977. The concept of the #GrandTour began in 1964, when #GaryFlandro of the #JetPropulsionLaboratory (#JPL) noted that an alignment of Jupiter, Saturn, Uranus, and Neptune that would occur in the late 1970s would enable a single spacecraft to visit all of the outer planets by using #GravityAssists. The particular alignment occurs once every 175 years. The two spacecraft that launched retained the same mission concept. Voyager 1's course was optimized for Saturn’s moon Titan flyby and Voyager 2 for the Grand Tour. Voyager 2 would reach Saturn nine months after Voyager 1, giving plenty of time to decide if it should proceed with the Grand Tour. And carrying #GoldDisc records. Distance from Earth 23,546,768,809 km Distance from Sun 157 AU Velocity (from the Sun) 16.9995 kps (61198.2 kph) One-Way Light Time 21:19:13 (hh:mm:ss) On Aug. 25, 2012, #Voyager 1 flew beyond the heliopause and entered #InterstellarSpace, making it the first human-made object to explore this new territory. At the time, it was at a distance of about 122 AU, or about 18 billion kilometres from the sun. This kind of interstellar exploration is the ultimate goal of the #VoyagerInterstellarMission. Voyager 2, which is traveling in a different direction from Voyager 1, crossed the heliopause into interstellar space on November 5, 2018. The Voyager spacecraft are still communicating through the #DeepSpaceNetwork and obtaining useful interplanetary, and possibly interstellar, fields, particles, and waves science data until around the year 2025 when the spacecraft's ability to generate adequate electrical power for continued science instrument operation will come to an end. https://www.instagram.com/p/CiHU3szJFu5/?igshid=NGJjMDIxMWI=

A small piece from a while ago: Interstellar Voyager Oil, 6 x 8 in . In 2012, the Voyager 1 spacecraft became the first human made object to enter interstellar space and it is the furthest away any human made object has ever traveled, at a distance of more than 20 light hours. In case it is ever found by intelligent life, Voyager carries a golden phonograph record of sounds and images of earth. . "The Voyager record would include greetings in sixty human languages and one whale language, an evolutionary audio essay, 116 pictures of life on Earth and ninety minutes of music from a glorious diversity of the world's cultures. The engineers projected a one-billion-year shelf life for the golden phonograph records. "How long is a billion years? In a billion years the continents of Earth would be so altered that we would not recognize the surface of our own planet. One thousand million years ago, the most complex life forms on Earth were bacteria. In the midst of the nuclear arms race, our future, even in the short term seemed a dubious prospect. Those of us privileged to work on the making of the Voyager message did so with a sense of sacred purpose. It was conceivable that, Noah-like, we were assembling the ark of human culture, the only artifact that would survive into the unimaginably far distant future." - Ann Druyan .
