JAXA scheduled an H2B launch for 2020-05-22 to deliver the Kounotori-9 cargo shuttle to the International Space Station.
After the Kounotori-9 launch, MHI will modify the H2B launchpad at Tanegashima to enable H3 missions by supporting different attach points and changing rocket exhaust pathways to reduce acoustic vibration during liftoff.
