25 August 1981: 4 years, 5 days after launch from the Kennedy Space Center, Florida, Voyager 2 made its closest approach to Saturn.

The probe continued outward to Saturn, Neptune and Uranus, continuously transmitting images and data. In 1990, the space probe passed beyond the limits of the Solar System.
Voyager 2 is now in interstellar space. It crossed the heliopause, where “solar wind” is slowed by the pressure of interstellar gas, 5 November 2018. It is still operating, 46 years after it was launched.
On 21 July 2023, an erroneous instruction caused Voyager 2 to turn its antenna away from Earth, but on 5 August 2023, contact was reestablished. A power reduction strategy is hoped to allow the space probe to continue operating until 2026.
As of 15 August 2024, Voyager 2 was 136 Astronomical Units from Earth (20,345,310,413 kilometers/12,641,989,788 statute miles/10,985,588,776 nautical miles). Radio signals, traveling at the Speed of Light, take 18 hours, 56 minutes to cross that distance. It continues outbound at a rate of 3.3 AU/year. (With respect to the Sun, Voyager 2 is traveling outbound at 15.35 kilometers per second (33,330.48 miles per hour/29,832.37 knots).

Not 25 August 1989, but 25 August 1981
I sure blew that one, didn’t I? Thanks for catching my error. The post has been corrected.
On 25 August 1981, I set a new land speed record of 98 mph on my brand new 1981 fire engine red Suzuki GS450E. I am sure Voyager 2 was traveling a bit faster than that!!
And she’s still rolling along out there somewhere..
