Sun-powered NASA spacecraft Juno begins 5-year trip to Jupiter

NASA has launched a probe on a five-year mission to Jupiter to learn more about the giant planet and how the solar system was formed. It's the first solar-powered mission to venture so far from the Sun.

The unmanned Juno spacecraft costing $1.1bn (£0.7bn), launched from Florida, will cruise beyond Mars to put itself in orbit around the gas giant in 2016.

Scientists said the spacecraft will study the giant planet's core, atmosphere, powerful magnetic field and auroras.

Once it reaches its target it will be the furthest-travelled solar-powered probe and the fastest man-made object in history after travelling at 160,000mph.

If you take everything else in our solar system (not including the sun), it would all fit inside Jupiter. In terms of understanding our solar system, NASA says, Jupiter's importance cannot be underestimated.

Now NASA is looking for the clues to help answer pressing questions about the early days of the solar system. Because whatever was in Jupiter at the beginning — more than 4.5 billion years ago, when the solar system was formed — is still there, scientists say, hiding in a mysterious gas giant made up of dust and gas left over by the Sun.

  1. To the author of this blog (also the visitors can note this):

    Few / all of the posts in this blog are word-for-word copy from my blog (including the images) and if the author of this blog is going to continue this, then they should be ready to face the consequences.

    This is strictly a warming. I hope the author of the blog takes this seriously.

    Thanks one and all.
