This program is quite ambitious among the other Japanese materials exposure tests; 3 sets of samples have been exposed for 1, 2 and 3 years in orbit in order to discover the fluence dependence of the material responses. We have learned a lot of lessons from this program. Based on the lessons learned, the “Advanced Material Exposure Test Working Group” has been established by the Committee on Space Utilization in 2007. This working group discussed the current problems of the material exposure program (flight tests) and proposed the future direction of the experimental methodologies. In this presentation, problems and new challenges discussed in this working group will be discussed., ISTS Special Issue: Selected papers from the 27th International Symposium on Space Technology and Science}, pages = {Th_1--Th_5}, title = {A Consideration of Future Flight Material Exposure Experiments in Japan: Advanced Material Exposure Test Working Group's Proposal}, volume = {8}, year = {2010}, yomi = {チヨウ, メンウ and イワタ, ミノル} }
