Watch NASA's Juno Space-Craft is almost at Jupiter

On 4 July, NASA’s basketball court-sized Juno spacecraft will lastly arrive at Jupiter, completing its 13.8 million-kilometre (8.6 million-mile) tour through the Solar System.
While there, Juno hopes to do 37 close approaches, collecting precious data for researchers back here on Earth. If all goes well, Juno will discover the gas giant closer than any other spacecraft in record, including 1974’s Pioneer 11.
At this time previous year our New Horizons spacecraft was final in for humanity’s first close views of Pluto," said Juno’s plan executive Diane Brown. "Now, Juno is poised to go closer to Jupiter than any spacecraft ever previous to to unlock the mystery of what lies within."
The work will not be easy, though. To perform the necessary experiment, Juno will have to fly inside Jupiter’s atmosphere, a place that's pretty strong.
Here, Juno will skill immense pressures from the planet’s fast rotation – a day on Jupiter is only 10 hours long – which creates a great magnetic field, coupled with extremely high levels of emission and atmospheric strain. In fact, NASA says that Jupiter’s radiation-filled environment is the harshest in the Solar System.
"Over the life of the work, Juno will be exposed to the equal of over 100 million dental X-rays," said Juno’s project manager Rick Nybakken.
"But, we are ready. We designed an orbit about Jupiter that minimises exposure to Jupiter’s harsh radiation environment. This orbit allows us to survive long enough to get the tantalising science data that we have travelled so far to acquire
The good reports is Juno is armoured like a knight ready for cosmic battle from its wires to its sensors. But the most important piece of defense is its 'titanium vault', which houses its central computer. Over the path of the mission, the uppermost energy electrons will penetrate the vault, create a spray of secondary photons and particle," said team leader Heidi Becker, who is accountable for monitoring radiation levels throughout the mission. "The steady bombardment will break the atomic bonds in Juno’s electronics."
at first launched on 5 August 2011, Juno is set to become the primary spacecraft to ever pull off such a full mission to the gas giant - but the first craft to arrive at Jupiter was Pioneer 10 back in 1973, which provided the opening close-up images of the planet.

Pioneer 10 was follow a year later by Pioneer 11, which flew within 34,000 kilometres (21,127 miles) of Jupiter’s clouds. Juno, on the other hand, will fly just 4,667 kilometres (2,900 miles) above the clouds.
Juno’s arrival at Jupiter couldn’t come at a improved time, either. Earlier this month, researchers working with the Very great Array – a radio telescope in New Mexico – were able to inspect what is behind Jupiter’s famed clouds. Now, Juno has a chance to confirm some of these findings up close.
Over the next months, we should start to see the results of the mission pour in presently like we did last year when New Horizons perform its Pluto flybys, capture the world’s imaginations in the process.
