Double Star PEACE
Launched in 2003 and 2004, Double Star was China's first purely scientific space mission and its first collaboration with ESA. One of the Double Star spacecraft orbited the Earth in an equatorial orbit, whilst the the second was in a polar orbit.
Each Double Star spacecraft has a payload consisting of Chinese and European instruments designed to study the magnetosphere and radiation belts. Part of these payloads are the PEACE instruments. These measure the 3D electron velocity distributions of the space plasma around the Earth.
The Double Star PEACE instruments were designed and built by MSSL. The Double Star PEACE instruments were apapted from Cluster II flight spares. Unlike the Cluster II instruments, PEACE on Double Star has only one sensor per spacecraft.
MSSL are responsible for the operation of the instruments and the processing and calibration of the raw instrument data. Prof. Andrew Fazakerley is the instrument's Principal Investigator.
PEACE is one part of a family of particle detectors developed for investigating a range of space plasmas. Instruments based on the heritage of PEACE have been flown on Cluster, Cassini and are proposed to fly on the future Solar Orbiter mission.
