EGG (re-Entry satellite with Gossamer aeroshell and GPS/Iridium)

The objective of the flight was to verify onboard instruments and operation of some systems related to EGG (re-Entry satellite with Gossamer aeroshell and GPS/Iridium) as part of the development project of the ''Membrane Aeroshell for Atmospheric-entry Capsule", which is expected to be applied for a future Earth re-entry system. The experiment is part of the preliminary-phase test prior to the actual satellite ''EGG" under development by a group led by the University of Tokyo. EGG will be deployed from the ISS.
