Voyager I and II space probes were launched in 1977 to primarily gather information about our solar system.
The images sent back from the probes have been used in textbooks. The probes have provided more information than originally visualized.
The real spacecraft trajectories of the Voyagers are updated every five minutes. Distance and velocities are updated in real-time. Voyager I is in interstellar space cruising at over 38,000 miles per hour. Voyager II on a different trajectory is cruising at over 34,000 miles per hour.
The probability of gaining more insights and knowledge as the Voyager I probe travels through Interstellar space is intriguing.
Both probes are journeying through Interstellar space.
