Voyager 1: NASA's Long-Lasting Spacecraft

Easy version (A2–B1)

Voyager 1 is a spacecraft that was launched in 1977. It was supposed to last five years but has worked for almost fifty years. NASA turned off one of its instruments to save power. Voyager 1 helps us learn about space.

Standard version (B1–B2)

Voyager 1 is a robotic space probe launched by NASA in 1977. Originally designed for a five-year mission, it has now been operational for nearly fifty years. Recently, NASA decided to turn off one of its science instruments to conserve power and prolong its mission. Voyager 1 is the farthest human-made object from Earth and has provided valuable information about our solar system.

Advanced version (C1–C2)

Launched on September 5, 1977, Voyager 1 was initially intended for a five-year mission to explore the outer planets of our solar system. Nearly fifty years later, it remains operational, making it the most distant human-made object. Recently, NASA engineers decided to shut down one of its remaining science instruments, not due to mission failure, but to extend its operational life as it runs low on power. The probe has provided invaluable data about Jupiter, Saturn, and beyond, utilizing a gravity assist technique that allowed it to explore multiple planets efficiently. Its continued operation is a testament to the ingenuity of space exploration.
