SEDA-AP [NASA]
JAXA's SEDA-AP (Space Environment Data Acquisition Equipment - Attached Payload) was an International Space Station (ISS) based payload to observe and predict the space weather.
SEDA-AP measured space environment (neutrons, plasma, heavy ions, high-energy light particles, atomic oxyen, cosmic dust) In the ISS orbit and environmental effects on materials and electronic devices.
Instruments on board of SEDA-AP were:
SEDA-AP was launched with JEM-EF on Space Shuttle mission Endeavour F23 (STS-127) to the ISS on 15 July 2009, where it was installed on the JEM-EF.
SEDA-AP was removed from the JEM-EF to be deorbited in the trunk of Dragon CRS-16, but as the mast could not be retracted, it was eventually released on 21 December 2018 into orbit to reenter naturally.
