49 kbits data storage. Deployable 6.6 m boom for magnetometer. Payload Instruments carried included a magnetometer, plasma analyzer, charged particle detector, ionizing detector, non-imaging telescopes with overlapping fields of view to detect sunlight reflected from passing meteoroids, micrometeoroid detectors, UV photometer, IR radiometer, and an imaging photopolarimeter. The spacecrafts' radio systems were also used to perform radio science. Pioneer 11 also carried a low-sensitivity fluxgate magnetometer.
