LAUNCH


Juno launched in August 2011 from Cape Canaveral, Florida, aboard an Atlas V 551 rocket. With five solid boosters, the V 551 is the most powerful of the Atlas rockets. The rocket operates in stages, so as it blasts Juno into space, segments of it fall off once they’re burned out. Here, the spacecraft is still in its cocoon form, its solar arrays and other components having been tucked away to fit in the rocket.   

JUNO IS GO FOR JUPITER

After the Atlas V rocket launches Juno into space, it will place the spacecraft in a parking orbit, in which it coasts around earth. At a particular point in this orbit, the rocket will fire again to put Juno on course toward Jupiter. Before separating from Juno, a set of thrusters will fire to give the space-craft some spin. Once Juno is deployed from the rocket, its solar arrays unfurl to begin charging its batteries.

While on its way to orbit, Juno communicates with ground controllers using the antennas on the Atlas rocket. But once the spacecraft detaches from the last rocket stage, it will communicate with Earth directly. NASA’s Deep Space Network, which has giant antennas in California, Spain and Australia, will lock onto its signal.

Juno will spend two years cruising the inner solar system before its trajectory takes it to Jupiter.


  • TEST AS YOU FLY

    Extensive testing is done to ensure Juno makes it to Jupiter


  • THE FLIGHT PLAN

    Juno’s trajectory takes it on a five-year voyage, circling the inner solar system before arriving at Jupiter.


  • AMOUNT OF FUEL

    Since there are no filling stations in space, Juno has to carry enough fuel for its entire trip.
