How Long Will the Voyager Spacecraft Last?

The Voyager probes, launched in 1977, have provided invaluable data from the solar system and beyond. Now on an interstellar mission, they face challenges as their fuel and power sources deplete. Hydrazine is used for trajectory corrections, while RTGs generate electricity. As power dwindles, instruments are being shut down. Despite this, the Voyagers have made significant contributions to our understanding of the solar system, exploring planets and moons, and will continue to travel through space even after they fall silent.

What is the current mission of the Voyager probes?

• To drift between stars and take measurements

• To explore the inner planets of the solar system

• To orbit around the sun indefinitely

• To return to Earth with samples

Which planets did Voyager 1 visit before entering interstellar space?

• Mercury and Pluto

• Uranus and Neptune

• Jupiter and Saturn

• Mars and Venus

What is the primary use of hydrazine in the Voyager probes?

• To propel the spacecraft forward
