NASA launched Juno, the solar-powered spacecraft again in 2011. It took about six years for Juno to cruise over to Jupiter. Juno appears like a propeller that’s been orbiting round our photo voltaic system’s greatest planet for about eight years now. It has captured some beautiful photographs and picked up groundbreaking information.
Now, Juno has cruised over to Io, the world’s most volcanically energetic spot within the photo voltaic system. That’s what scientists are literally learning. In spite of everything, Juno price like a billion {dollars} to construct.
