What characteristic defines a Flyby mission like Mariner or Voyager during data acquisition?

Answer

Gathering data during a brief window before continuing trajectory

Flyby missions are characterized by their high-speed trajectory past a target planet. Spacecraft like Mariner or Voyager execute a brief, rapid pass, often described as being like high-speed mail carriers. During this short window, the onboard devices, such as wide-angle cameras and magnetic field measuring instruments, must rapidly acquire all the necessary data before the craft continues its path out of the planet's sphere of influence, making efficiency in data acquisition paramount.
