MEXT(Ministry of Education, Culture, Sports, Science and Technology) announced redesigned HTV concept for 50% cost reduction.This version will be introduced started from HTV10.http://mainichi.jp/select/news/20150520k0000e040188000c.html
This would be launched on an H-2A-204?
If my (very bad) understanding of Japanese is correct, they are looking at cutting the cost by about 100 billion yen (~$US 82m) and lighten the spacecraft up by 30%, is that correct?
