NASA will hold a special Science Update at 1 p.m. EDT on Thursday, April 28, to discuss the unprecedented journey of NASA’s twin Voyager spacecraft to the edge of our solar system.

The event will be held in NASA headquarters’ Webb auditorium at 300 E St. SW, in Washington. It will be broadcast live on NASA Television and streamed at http://www.nasa.gov

After 33 years in space, the spacecraft still are operating and returning data from about 10 billion miles away from our Sun. The Voyagers also carry a collection of images and sounds from Earth as a message to possible life elsewhere in the galaxy.

The participants:

* Ed Stone, Voyager project scientist and professor of physics, California Institute of Technology

* Ann Druyan, creative director, Voyager Interstellar Message Project; Carl Sagan’s co-author and widow

* Suzanne Dodd, Voyager Project Manager, Jet Propulsion Laboratory, Pasadena, Calif.

* Merav Opher, Voyager Guest Investigator and assistant professor of astronomy, Boston University

Reporters also may ask questions from participating NASA field centers or by phone. Journalists must send their name, affiliation and telephone number to Dwayne Brown at dwayne.c.brown@nasa.gov by noon on Wednesday, April 27, for dial-in information.
