us space agency says ” next step to enable Voyager 1 send science data space again.”
Voyager 1 was launched from earth in 1977 on a tour of outer planets but then it just kept going.
it moved beyond the bubble of the gas emitted by sun – called as heliosphere in 2012 and now it is in interstellar. Which contain gas, magnetic fields and other stars.
Their powers come from RTG – RADIOISOTOPES THERMOELECTRIC GENERATORS. EHICH CONVERT DECAYING PLUTONIUM INTO ELECTRICITY.
Its little sister voyager 2 also launched which covered 20 billion km recently .Even though they are travelling 15km/second, they could not approach another star in near time of tens of thousands of years.
Voyager 1 in its journey to vast open ended interstellar space has carried GOLDEN RCORDS – 12 INCHES GOLD PLATED COPPER DISCK INTENTE TO CONVEY THE STORY OF OUR WORLD TO EXTRATERRESTRIAL. – COULD BE WHAT WE CALL AS ALIENS.
It sounds so mysterious and thrilling just to think about that.
Power banks are expected to depleted after 2025 , it will then continue to wander the MILKY WAY, potentially for eternity, in silence.
Total cost to make Voyager 1 was 865 million $, with later adopted Voyager interstellar mission costing an extra $ 30 million.
