The mystery of what lies beneath the relentless swirling clouds of Jupiter may soon be solved as On the 4th of July 2016, NASA's Juno spacecraft will arrive at the huge gas planet, after a space voyage of almost 5 years. So before NASA's Juno spacecraft arrives at its destination, let's look at 5 amazing facts about Juno's Mission to Jupiter!

1-Juno is the fastest man made craft ever, traveling at an incredible speed of approximately 165,000 miles per hour relative to earth. This incredible speed is due to the gravitational tug of Jupiter and the crafts initial launch speed. However, when Juno finally arrives and enters Jupiter's orbit, the craft will start a 35 minute engine burn to slow it down to around 130,000 miles per hour and allow Itself to be captured by Jupiter's gravity. This will mean that Juno, is not only the fastest man made craft in history, but it will also be the fastest space craft ever to enter orbit around a planet!
2- Juno has ventured farther into deep space than any other solar powered probe, at an incredible distance of 493 million miles from the sun. This has been achieved because of the space crafts three huge 9 meter long solar panels that contain approximately 18,000 state of art solar cells and generate around 500 watts of electricity even while orbiting Jupiter.
3- Juno will fly closer to Jupiter's cloud tops than any other space craft sent to the giant gas planet in the past. It will pass by as close as 3000 miles above the clouds each time it performs its 37 orbits of Jupiter during its mission and study the gas planets atmosphere, but also take the first pictures of Jupiter's poles and dazzling aurora that are hundreds of times more brighter than that on Earth.
4- The Juno mission is scheduled to orbit Jupiter for 20 months, but during this time the probes sensitive electronics will be bombarded by charged particles moving at super fast speeds. This is because Jupiter's magnetic field is 20,000 times more intense than Earths. The Juno spacecraft is able to survive this short period of time because of a state of the art radiation vault, made of titanium, which shields and protects all of Juno's important electronic units.
5- The Juno mission will come to an end in February 2018 and the probe will perform a maneuver that will crash the space craft in to Jupiter's atmosphere. This is to try and prevent the moons of Jupiter, becoming contaminated with resistant Earth life that might be surviving on or in the craft. Scientists know that some Earth born microbes can survive the harshness of space and a moon like Europa, that may harbour alien life within its deep ocean could become contaminated, which might cause big consequences. So, Juno will plunge its self in to Jupiter, marking the end of the mighty Juno mission.
