V'ger must evolve

NASA announces Voyager 1 is reaching the edge of the solar system.

Launched in 1977, the unmanned ship is about 10.8 billion miles away from the sun, in an area of the solar system called the heliosheath. The heliosheath is the final area of the solar system where the sun's wind blows.

NASA reports:

"Voyager 1 has crossed into an area where the velocity of the hot ionized gas, or plasma, emanating directly outward from the sun has slowed to zero... The event is a major milestone in Voyager 1's passage through the heliosheath, the turbulent outer shell of the sun's sphere of influence, and the spacecraft's upcoming departure from our solar system."

The BBC hosts audio of Voyager project scientist Ed Stone.

On board: One of two Golden Records (image) composed of sounds and music representing life on Earth.

The Voyager Golden Record has "115 images and a variety of natural sounds, such as those made by surf, wind and thunder, birds, whales, and other animals... musical selections from different cultures and eras, and spoken greetings from Earth-people in fifty-five languages."

Also: The late, great Carl Sagan accompanied by an immortal Vangelis soundtrack.

And: From Voyager's Golden Record, "Kinds of Flowers".
