The Juno “brain and central nervous system” is called the C&DH, for Command and Data Handling subsystem. The C&DH controls the functions of the spacecraft, collects and organizes the data from the science instruments, checks on the health and safety of the spacecraft, and controls the transmission of data back to Mission Control. Juno’s brains are powerful enough to protect it from most malfunctions by putting the spacecraft into a safe mode if engineering sensors identify an anomaly, and waiting for further instruction from Earth. Amazingly, this computer is very simple – less powerful than your typical laptop computer, and doesn’t use much power
