Why Didn't Voyager Visit Pluto?
Flash Modin writes: NASA built the twin Voyager spacecraft for a rare planetary alignment that put Jupiter, Saturn, Uranus, and Neptune within reach at once. Originally, Voyager 1 was programmed to see Pluto in 1986, but managers targeted Saturn's planet-like moon Titan instead. That choice made Pluto impossible by vaulting Voyager 1 from the orbital plane. Interestingly, Voyager 2, which couldn't reach Pluto, made the case for New Horizons by revealing Neptune's moon Triton as a kidnapped Pluto. "I'm very glad that they chose not to go to Pluto in 1986," says New Horizons head Alan Stern. "We'll do a better job at Pluto with modern instruments than they would have, and they did a much better job at Saturn..."
but there is a secret alien base on Pluto
