Japan’s Mitsubishi Heavy Industries (MHI) has successfully launched one of its H-IIB rockets, carrying a payload of supplies, experimental materials and new replacement batteries to help power the International Space Station. The rocket, commissioned by Japan’s Aerospace Exploration Agency, took off from Japan’s Tanegashima Space Center at its scheduled instantaneous launch window of 12:05 PM EDT (1:05 AM JST), succeeding during its second try after an initial attempt was scrubbed earlier this month.

This is the eighth launch of the H-IIB, and its H-II Transfer Vehicle (HTV), and it’s the second-to-last planned mission for the H-IIB before this series of MHI rocket is retired. It’s set to be replaced by the higher capacity, lower cost H3, which MHI hopes to fly for the first time next year.
