After a nearly five-year trip, Nasa’s solar-powered spacecraft Juno is passing Jupiter’s inner moons as it readies for humanity’s closest encounter with the biggest planet in the solar system. During its 20-month stay, Juno will circle the gas giant 37 times.From vantage points as close as 4,800 km from the planet’s cloud tops, the spacecraft is to not only search for water but find out whether Jupiter has a dense core beneath its atmosphere.
