‘Welcome to Jupiter’: NASA Mission Puts Juno in Orbit After Five-Year Journey


July 5th, 2016

Via: Guardian:

After a five-year voyage across 1.8bn miles (2.8bn km), Nasa’s Juno spacecraft has reached Jupiter and successfully entered its orbit.

Juno’s mission is to peer through Jupiter’s cloud-socked atmosphere and map the interior from a unique vantage point above the poles. Among the lingering questions: How much water exists? Is there a solid core? Why are Jupiter’s southern and northern lights the brightest in the solar system?

“What Juno’s about is looking beneath that surface,� Bolton said before the craft’s arrival. “We’ve got to go down and look at what’s inside, see how it’s built, how deep these features go, learn about its real secrets.�

The fifth rock from the sun and the heftiest planet in the solar system, Jupiter is what’s known as a gas giant — a ball of hydrogen and helium — unlike rocky Earth and Mars.

Bristling with instruments, Juno will peer deep beneath Jupiter’s clouds to learn how the planet formed; what drives its brilliant aurorae; and how its complex weather systems produce the giant red spot and the swirling, enigmatic stripes that decorate its outer layers.
