Voyager one still going strong.

According to the CNN web site. The Voyager one spacecraft is still going strong. The Voyager was launched 1977 to photograph the big gas planets. But has gone on to out of the solar system. The Voyager has now gone over 7.5 billion miles and NASA will be able to track the spacecraft for another 20 years.

Indeed, great Science Mission. We, first time, can learn in situ science on the outer boundry of solar system.

Tiny Voyager Exits Sun's Realm
Probe Enters Area of Space Where Solar Influence Wanes

WASHINGTON (May 25, AP) - NASA's Voyager 1 has reached the final frontier of our solar system, having traveled through a turbulent place where electrically charged particles from the Sun crash into thin gas from interstellar space.

Astronomers tracking the little spaceship's 26-year journey from Earth believe Voyager 1 has gone through a region known as termination shock, some 8.7 billion miles from the Sun, and entered an area called the heliosheath.

"Voyager 1 has entered the final lap on its race to the edge of interstellar space," Edward Stone, Voyager project scientist at the California Institute of Technology, said in a statement released on Tuesday.

Voyager watchers theorized last November that the craft might be reaching this bumpy region of space when the charged solar particles known as the solar wind seemed to slow down from a top speed of 1.5 million miles per hour.

This was expected at the area of termination shock, where the solar winds were expected to decelerate as they bump up against gas from the space beyond our solar system. It is more than twice as distant as Pluto, the furthest planet in our system.

By monitoring the craft's speed and the increase in the force of the solar wind, Voyager scientists now believe the craft has made it through the shock and into the heliosheath.

Predicting the location of the termination shock was hard because the precise conditions in interstellar space are unknown and the termination shock can expand, contract and ripple, depending on changes in the speed and pressure of the solar wind.

"Voyager's observations over the past few years show the termination shock is far more complicated than anyone thought," said Eric Christian, a scientist with NASA's Sun-Solar System Connection program.

Voyager 1 and its twin spacecraft Voyager 2 were launched in 1977 on a mission to explore the giant planets Jupiter and Saturn. The pair kept going, however, and the mission was extended.

Voyager 2 went on to explore Uranus and Neptune, the only spacecraft to have visited these outer planets. Both Voyagers are now part of the Voyager Interstellar Mission to explore the outermost edge of the Sun's domain.

Both Voyagers are capable of returning scientific data from a full range of instruments, with adequate electrical power and attitude control propellant to keep operating until 2020.

Wherever they go, the Voyagers each carry a golden phonograph record which bears messages from Earth, including natural sounds of surf, wind, thunder and animals. There are also musical selections, spoken greetings in 55 languages, along with instructions and equipment on how to play the record.

Voyager was launched September 5, 1977 on a Titan III Centaur.

Back in January 2005, Voyager 1 surpassed 10,000 days of operation

After a million years when it reaches another stellar system our records will be known by some intelligent men in that star.

NASA is actually considering scrapping the Voyager project along with other missions such as Ulysses.  This comes to save several million dollars.  Sad since the Voyager project needs less than ten million dollars to operate.
