Exploring the Fascinating Aspects of Voyager 1: The Pioneering First Interstellar Spacecraft Humankind Launched
In a cosmic odyssey that has captivated scientists and the public alike, the Voyager 1 spacecraft continues its groundbreaking mission, exploring the outermost reaches of our Solar System. Launched in 1977, Voyager 1 has outperformed expectations, providing invaluable data and carrying a message from Earth to the stars.
Voyager 1, which was launched 16 days after its sister craft Voyager 2, will never overtake it due to its faster relative speed. This speed, a staggering 62,000 kilometres per hour, makes Voyager 1 the fastest human-made object ever sent into space[1].
Both Voyager spacecraft carry small metal plaques identifying their time and place of origin, as well as a phonograph record containing sounds and images of Earth, details about the diversity of life, and the cultures on our planet[2]. This cosmic time capsule is intended as a message from humanity to any extraterrestrial life forms that may encounter the spacecraft.
Voyager 1 is currently the farthest human-made object from Earth, having left our solar neighbourhood in 1990. Its journey has led it to the edge of the Solar System, where it is estimated to enter the Oort cloud in about 300 years from now[3]. After reaching this vast shell of icy objects, it will take approximately 30,000 years to pass through[4].
Regarding its operational lifetime, Voyager 1 is expected to continue its mission until the early 2030s, when its power sources—plutonium batteries—will no longer support its instruments effectively. NASA has been carefully managing its power usage to keep key sensors running as long as possible, but eventually the probe will run out of fuel and cease communication[2][3][4].
Despite this, Voyager 1 remains an active mission well into the 21st century. Each of the Voyager spacecraft obtains their power from three RTGs (radioisotope thermoelectric generators). Moreover, astronomers on Earth have fitted the Voyager 1 spacecraft with a message from Earth, designed to be read by potential alien civilizations[5].
In summary, Voyager 1's journey through the Solar System and beyond will continue long after it stops sending data back to Earth. Its legacy as a testament to human curiosity and ingenuity will endure, inspiring future generations to reach for the stars.

The Voyager 1 spacecraft, launched in 1977, carries a message from Earth to the stars, intended as a communication with extraterrestrial life forms, making it part of the broader scope of space-and-astronomy and technology. This mission, still active in the 21st century, is significant in the history of science, challenging our understanding of space and the Solar System. Since leaving our solar neighbourhood in 1990, Voyager 1 has been exploring the edge of the Solar System, providing valuable data to scientists, thereby contributing to the advancement of astronomy.
