🚀 Voyager 1 — 15 Billion Miles Away and Still Running on Just 69 KB of Memory.Launched in 1977, NASA’s Voyager 1 remains humanity’s most distant explorer — now more than 15.8 billion miles (≈ 25.4 billion km) from Earth, traveling through interstellar space. 🌌What’s mind-blowing is what keeps it running:🧠 Just 69 kilobytes of memory — about one-hundredth of what a basic smartphone photo takes.💾 A digital eight-track tape recorder, not for music but to store scientific data when it can’t transmit in real time.💡 Assembly-language software, written for custom 1970s processors, still executes flawlessly after nearly half a century.The myth that Voyager runs on “Fortran code” isn’t quite right — Fortran was used on Earth for mission planning, while the spacecraft itself runs hand-written assembly directly on its hardware.Each command takes over 22 hours to reach Voyager 1 — yet NASA engineers are still able to send fixes, reroute code around damaged memory, and keep its instruments alive. In 2024, they even recovered data after a computer glitch by moving instructions to a different part of its 69 KB memory — a stunning example of ingenuity and persistence.Voyager 1’s endurance is a time capsule of human brilliance — proof that great engineering, not just great technology, stands the test of time. 🌍✨_#Voyager1 #NASA #SpaceExploration #EngineeringMarvel #InterstellarMission #DeepSpace #ScienceFacts #Since1977 #HumanAchievement #BeyondTheSolarSystem #SpaceHistory #TechThatLasts #VoyagerLegacy #CosmicJourney #Astrophysics #InterstellarTravel #Innovation #SpaceOdyssey #AstronomyLovers #TheFinalFrontier
