help Voyager 1 FAQ
How did Voyager 1 become the first human-made object to enter interstellar space?
Voyager 1 was launched in 1977 and crossed the heliopause into interstellar space in 2012, which is the widely cited date for that milestone. The mission marked a major turning point in deep-space exploration history.
What was Voyager 1's planetary path before its current phase?
The probe completed major flybys of Jupiter and Saturn, including iconic imaging of the gas giants and their moons. These encounters set the template for long-range trajectory planning in deep-space mission design.
What is on Voyager 1 that carries a message about humanity?
Like Voyager 2, Voyager 1 carries a gold-plated record designed to represent human culture and science. The record is one of the most discussed artifacts in planetary missions because it is physically preserved outside Earth orbit.
Is Voyager 1 still operational in practical terms?
The spacecraft is still in operation and continues to send weak but valuable signal data. It uses a radio link to Earth via NASA's Deep Space Network rather than any direct autonomous internet architecture.
