Voyager Project Manager Ed Massey of JPL says the survival of the two spacecrafts is a credit to the robust design of the spacecraft, and to the flight team, which is now down to only 10 people.
"But it’s these 10 people who are keeping these spacecrafts alive. They’re very dedicated. This is sort of a testament to them, that we could get all this done".
Between them, the two Voyagers have explored Jupiter, Uranus, Saturn and Neptune, along with dozens of their moons. In addition, they have been studying the Solar Wind, the stream of charged particles spewing from the sun at nearly a million miles per hour.Set 05, 2006

01-vg1_p20945.jpgJupiter, in true colors62 visiteThe spacecrafts are traveling at a distance where the Sun is but a bright point of light and solar energy is not an option for electrical power.
The Voyagers owe their longevity to their nuclear power sources - known as Radioisotope Thermoelectric Generators, provided by the Department of Energy.
Voyager 1 is now at the outer edge of our Solar System, in an area called "The Heliosheath", such as the zone where the Sun's influence wanes. This region is the outer layer of the 'bubble' surrounding the Sun, and no one knows how big this bubble actually is. Voyager 1 is literally venturing into the great unknown and is approaching interstellar space.
Traveling at a speed of about 1,6 MKM per day (!), Voyager 1 could cross into interstellar space within the next 10 years. Set 05, 2006

00-vg1_p20938.jpgJupiter, in true colors56 visiteUn nuovo viaggio in quelle che sono (ormai) le "Memorie dell'Astronautica".
Si tratta di Giove e del suo stupendo Sistema di lune, attraverso gli occhi di due grandissimi "Esploratori": le Sonde NASA, Voyager 1 e 2.
Voyager 1, il 15 Agosto 2006, ha raggiunto la (davvero "astronomica") distanza di 100 U.A. dal nostro Sole (o, se preferite, la distanza di circa 15 miliardi di Km dal Sole), confermandosi come l'oggetto fabbricato dall'Uomo "più distante" dal suo Mondo di origine.
Ecco un commento al riguardo da parte del Dr Edward Stone (ex Direttore del NASA JPL di Pasadena):"...what you can't predict is that the spacecraft isn’t going to wear out or break: Voyager 1 and 2 run 24 hours a day, 7 days a week, but they were built to last - Stone said.
The spacecrafts have really been put to the test during their nearly 30 years of space travel, flying by the outer planets, and enduring such challenges as the harsh radiation environment around Jupiter". - continuaSet 05, 2006
