|
|
NASA had developed a completely new kind of rocket that could send the craft from planet to planet
|
|
|
the four planets were approximately aligned on one side of the Sun and we used the gravity of each planet to speed up the spacecraft to get to the next one in its path
|
|
|
the spacecraft stopped off to collect fuel on the satellites of each planet before proceeding to the next one
|
|
|
we used laser beams to propel the spacecraft into the outer solar system, where sunlight is dim

Detailed explanation-1: -The Voyager mission was designed to take advantage of a rare geometric arrangement of the outer planets in the late 1970s and the 1980s which allowed for a four-planet tour for a minimum of propellant and trip time.
Detailed explanation-2: -Outside the Roche limit, an object will be deformed by the planet’s tidal force, but will otherwise be OK. If an object gets inside the Roche limit, though, the tidal force from the planet will be stronger than the force of gravity holding the object together, so it will be destroyed.
Detailed explanation-3: -While Voyager 1 focused on Jupiter and Saturn, Voyager 2 visited both those planets and also ventured to Uranus and Neptune. Voyager 2’s mission to those last two planets would be humanity’s only visit in the 20th century. Voyager 2 is now traveling through interstellar space.
Detailed explanation-4: -Voyager 2 needed to travel much further to the two outermost planets so was launched first due to the preferable planetary conditions. Voyager 1 would be launched second, for its much shorter journey, but would still overtake Voyager 2 before reaching Jupiter.
