- NASA's Voyager 1 spacecraft, is about to make history again. It is the first spacecraft from Earth to reach the vast expanse of space where wind from the Sun meets the thin gas that fills interstellar space.
- First, Voyager 1 must pass through the termination shock---a turbulent zone that is the source of beams of high-energy particles. Voyager's journey through this violent region will give scientists their first direct measurements of our solar system's unexplored final frontier. Some scientists think that the passage has already begun.
Voyager 1 - Artist's Conception
- Launched on September 5, 1977, Voyager 1 explored the giant planets Jupiter and Saturn before being propelled toward deep space by Saturn's gravity. It is now approaching, and may have temporarily entered, the region beyond termination shock. At more than 13,000,000,000 kilometers (approximately 8,000,000,000 miles) from the Sun, Voyager 1 is the most distant object from Earth built by humanity.
- The termination shock is where the solar wind, a thin stream of electrically charged gas blown constantly from the Sun, is slowed by pressure from gas between the stars. At the termination shock, the solar wind slows abruptly from its average speed of about 700,000 down to 100,000 miles per hour.
