Voyagers 1 and 2

[Christopher K.]

It is the longest successful NASA mission. They are the only spacecraft to explore interstellar space. We are now celebrating the mission's forty-fifth anniversary--or if you like, beginning a five-year celebration of its fiftieth anniversary!

Voyager 2 left Earth on 20 August 1977; Voyager 1 followed on 5 September in the same year. They were sent into space on Titan-Centaur rockets.

For the APOD for 2023, Nemiroff and Bennell have picked Voyager’s famous Pale Blue Dot picture. We’ve been through a lot these past two years. Hopefully we will have an abundance of measured, well-considered responses to real and really imperative issues this coming calendar year.
