NASA and the Smithsonian National Air and Space Museum will celebrate 40 years of the Voyager 1 and 2 spacecraft -- humanity's farthest and longest-lived mission -- with a public event at 9:30 a.m. PDT (12:30 p.m. EDT), Tuesday, Sept. 5.

The observance will take place at the Smithsonian's museum located at Independence Avenue at 6th street SW in Washington. The event will be broadcast live on NASA Television and streamed on the agency's website.

Activities will include panel discussions about the Voyagers' creation and mission history, their unprecedented science findings and imagery, impact on Earth's culture and how the spacecraft inspired countless scientists, engineers and the next generation of explorers. The event also will include a galactic message transmitted toward the Voyager 1 spacecraft by a celebrity guest.

The Voyagers' original mission was to explore Jupiter and Saturn. Although the twin spacecraft are now far beyond the planets in the solar system, NASA continues to communicate with them daily as they explore the frontier where interstellar space begins.

Participants in the Sept. 5 event are:

Thomas Zurbuchen, associate administrator for NASA's Science Mission Directorate, NASA Headquarters, Washington

Ed Stone, Voyager project scientist, Caltech, Pasadena, California

Suzanne Dodd, Voyager project manager, NASA's Jet Propulsion Laboratory, Pasadena

Gary Flandro, Voyager Mission Grand Tour creator, University of Tennessee, Knoxville

Alan Cummings, Voyager researcher, Caltech

Ann Druyan, Creative Director of the Voyager Interstellar Message
