In 1930, Clyde Tombaugh, a 25-year-old astronomer, observed a small, tiny object in the night sky.
He was working on Lowell Viewer in Flagstaff, Arizona, for nearly a year when he used a magnifying glass – a type of microscope that can scan and compare images – to see what was the ninth time in our solar system : Pluto.
According to all accounts, Pluto was amazing. At one time, astronomers believed that they could be larger than Mars (were not). Its unusual 248-year cycle has been identified crossing the path of Neptune. Today, Pluto is known for being the largest in the Kuiper Belt – but he is not considered a planet.
In 2006, a International cooperation voted to degrade Pluto, defining the planet as a body revolving around the sun, orbiting the earth, and “leaving the orbits” – meaning that it has grown so much, that there are no bodies in its orbits except for its own moons. Since Pluto did not look at the third box, it was considered a small planet.
Now a new mission offered at NASA requires a closer look at Pluto and his nearby machine. By the end of 2020, Persephone could investigate whether Pluto has oceans and how the universe and the atmosphere have changed.
Persephone is able to send a high-speed camera to fly around Pluto for three years and photograph it on top of it and its main moon, Charon.
But why is Pluto worth visiting?
The same year Pluto was hit on its planets, NASA sent New Horizons Work on the Pluto and Kuiper Belt to better understand our solar system.
Arriving in Pluto in 2015, New Horizons hit what was a scientific treasure. Pluto’s approach revealed the ever-expanding mountains, the walking ice, and the amazing history of land history.
Carly Howett, a planetary scientist and Persephone’s chief researcher, says New Horizons showed us how difficult the place is.
“It’s not that New Horizons really had a new technology, but it does give people a sense of what Pluto’s system would look like,” Howett said. “The world, for the first time, has seen Pluto.”
