Juno spacecraft assembly. NASA's Juno spacecraft being lifted out of a thermal vacuum chamber following tests to simulate the environment of space over the range of conditions the probe will encounter during its mission. Juno was launched on 5th August 2011, on a five-year flight to Jupiter. After arriving in July 2016, it will orbit the planet 32 times over the following year, gathering information about Jupiter's atmosphere, magnetic field, and gravitational field.
