After a five year trek, the spacecraft dubbed "Juno" has finally made it to Jupiter. The goal of the Juno mission is for NASA to find out more about the origins and general functioning of this mysterious planet via the spacecraft. Jupiter is the largest planet in our solar system, and we have a lot to learn about this grand planet.

About the Spacecraft

According to NASA, the spacecraft Juno was given its name due to Roman and Greek mythology. "Jupiter drew a veil of clouds around himself to hide his mischief," NASA reports. "It was Jupiter's wife, the goddess Juno, who was able to peer through the clouds and reveal Jupiter's true nature." 

Juno's mission has been a long time in the making.

Launched on August 5th, 2011, the spacecraft did not enter Jupiter's orbit until July 4th, 2016. This is considered a big step for #Space exploration. The plan is for Juno to orbit Jupiter for 20 months before beginning its journey back to Earth in February 2018. Similar to the Mars Curiosity rover, lots of time will be needed to explore the full scope of our solar system's biggest planet.

The purpose

There are many questions that NASA hopes to have answered during this trip. Juno will explore "the existence of a solid planetary core, map Jupiter's intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet's auroras," says NASA. "Juno will let us take a giant step forward in our understanding of how giant planets form and the role these titans played in putting together the rest of the solar system."

NASA also intends to solve mysteries such as the amount of water in the atmosphere, the planet's specific magnetic and gravity fields, the measurements of the composition and temperature, and finding out more information about the planet's "enormous" magnetic force field. Juno has a plethora of #Science tools and equipment that will help it conduct research on its journey.
