SSSat 1, 2

SSP (from onboard camera) [JAXA]

The SSSat (Solarsail Subpayload Satellite, soraseiru sabupeiro-do) is a experimental a 15-meter diameter solar sail, based on the experience of a earlier suborbital mission. The solar sail experiment was mounted on the second stage of the M-5 launch vehicle instead of balast and was to deploy after the primary and piggy-back satellites were jettisoned.

It deployed from the stage at 2146 UTC but opened only incompletely.
