Juno is the NASA’s new mission currently orbiting the planet Jupiter. It was launched from Cape Canaveral Air force station on 5th August 2011 and has finally reached after 5 years on 4th July 2016.
The Spacecraft was launched to study Jupiter’s gravity fields, composition, and polar magnetosphere. It is the second spacecraft to orbit Jupiter after Galileo probe which orbited from 1995-2003.
The US space agency has successfully put a new probe in orbit around Jupiter.
The tones transmitted through spacecraft confirmed the breaking exercise has gone as per planning.
Orbit insertion on Tuesday has put Juno in a large ellipse around the planet which takes just 53 to complete.
In Mid-October there will be a second burn of the rocket engine that will tighten this orbit in 14 days. This will involve repeat passes just a few thousand kilometers above the cloud tops.
At each close approach, Juno will use its eight remote sensing instruments and its camera to peer down planet’s many layers, to measure their composition, temperature, motion and other properties. Scientist’s priority is to determine the abundance of oxygen at Jupiter.
“How much water Jupiter has tells us a lot about where the planet formed early in the Solar System, We think that Jupiter may not have formed where it is today, and if it formed further away or closer in – that tells us a lot about how the Solar System in general form. Because when we look at planets around other stars we see quite a menagerie of possibilities. Scientists plan to use the spacecraft to sense the planet’s deep interior. They think the structure and the chemistry of its insides hold clues to how this giant world formed some four-and-a-half-billion years ago.” explained team-member Candy Hansen.
