Log into Google and you will see a doodle celebrating NASA’s triumph. It’s $1.1 billion worth Juno spacecraft has successfully slipped into the orbit of planet Jupiter, which may as well be the first step towards probing into the origin of solar system.
The observatory spacecraft Juno was launched five years ago from Cape Canaveral, Florida and since covered 1.7 billion miles (2.7 billion kilometers) and was traveling at a speed of more than 130,000 miles per hour (209,200 kilometers per hour) and then it fired its engines to slow down enough to be captured into Jupiter’s orbit.
It was a moment of cheer at NASA’a Jet Propulsion Laboratory in Pasadena, California as the spacecraft entered the biggest planet in our solar system at 11.53 pm (0353 GMT) Tuesday.
Juno, named after the Roman goddess who was the wife of Jupiter, the god of the sky in ancient mythology, will get closer (3100 miles) than its predecessor Galileo, and is expected to find out more about how much water the largest planet in our solar system holds and the makeup of its core and the information will help us figure out how the planet and the others in the vicinity including Earth, formed billions of years ago. Juno will be circling Jupiter 37 times and find out as much as possible before taking the final plunge in 2018.
