Achievement of Long-term On-orbit Operation of the SIMPLE Inflatable Extension Mast

Abstract

An extension demonstration of a space inflatable mast and subsequent long-term operation for 845 days on orbit were performed to show the advanced design technology and practical utility of space inflatable structures. The experiment verified the long-term availability of the inflatable extension mast and good establishment of the design technology, including development testing know-how for space-borne inflatable structures, by considering possible degradation effects simulated using a finite-element method analysis tool developed in parallel with the mission. The space inflatable extension mast achieved the extra success level set out in the mission plan.
