Proba

Proba (PRoject for On-Board Autonomy, 1) was a European Space Agency technology development minisatellite with a mass of 94 kg.

It carried a radiation detector, an IR spectrometer, debris impact detectors, Earth imaging cameras, and an experimental spacecraft processor for spacecraft autonomy experiments. The satellite was built by Verheart in Belgium using the MiniSIL bus developed by SI of England, and was controlled from Belgium.

Mass: 94 kg (207 lb).
