A Five-Year Trip

Juno spent two years looping through the inner solar system, then slingshotted past Earth to gain speed for its long trip to Jupiter.

Jupiter Arrival

Juno is now accelerating toward Jupiter, pulled in by gravity. On July 4, Juno will fire its main engine for 35 minutes to slow down and be captured into orbit around the planet.

Two-Week Orbits

After two long orbits of about two months each, Juno will settle into a series of tighter orbits, passing Jupiter every 14 days. Juno’s final orbit in early 2018 will graze Jupiter’s clouds, incinerating the spacecraft.

A Spinning Spacecraft

Juno is the most distant solar powered spacecraft. Its spinning hexagonal body supports three large solar panels to capture the dim light of the outer solar system. Instruments are fixed between the solar panels for a wide field of view.

Pole to Pole

Juno will pass close to Jupiter’s surface to avoid the punishing bands of radiation surrounding the planet. The orbits are timed to gradually scan the planet from pole to pole in evenly spaced bands, seen here looking down on Jupiter’s north pole.

On July 4, the Juno spacecraft will arrive at Jupiter. The solar-powered craft will spend 20 months studying the planet’s composition and history, then burn up in Jupiter’s atmosphere.
