Purpose of the flight and payload description

In the framework of the development of better technologies related to rocket recovery technology a balloon-borne mission was carried out by ISAS to investigate the parachute opening characteristics, especially the low opening load coefficient.

The gondola used in this experiment transported several test items that were dropped one after another from the balloon in flight, to observe the parachute opening, and the parachute behaviour during the slow descent to the sea. The telemetry of the experiment was received at the Sanriku Balloon Center, while an on-board 8 mm camera taped the process for post-flight analysis.

In the image at right we can see the gondola floating in the ocean after the test.
