The NASA spacecraft, Juno, is about to complete its 1.8 billion mile journey to Jupiter and go into orbit around the giant planet on July 4. The journey took five years and now Juno will endeavor to understand the origin and evolution of Jupiter, look for a solid planetary core, map the magnetic field, measure water and ammonia in deep atmosphere, and observe auroras.

The Juno telecom system operates on the NASA Deep Space Network (DSN) on the X-Band at receive frequency of 7153.065586 MHz and transmit frequency of 8404.135802 MHz. A radio signal would take 48 minutes to travel to or from the spacecraft.

The antennas are:
High-Gain Antenna (HGA) a 2.5-m dual-band (X and Ka) dual reflector
Toroidal Low-Gain Antenna (TLGA) a biconical design operating on the X-Band at receive frequency of 7153.065586 MHz and transmit frequency of 8404.135802 MHz
Medium-Gain Antenna (MGA)
Forward Low-Gain Antenna (FLGA) and Aft Low-Gain Antenna (ALGA)
ET would be able to easily phone home!
