Some vehicles mount magnetometers on simpler, existing appendages, such as specially-designed solar arrays (e.g., [[Mars Global Surveyor]], [[Juno (spacecraft)|Juno]], [[MAVEN]]). This saves the cost and mass of a separate boom. However, a solar array must have its cells carefully implemented and tested to avoid becoming a [[Electromagnet|contaminating field]].
