Following a setback final week due to a fire on the launch pad, Mitsubishi Heavy Industries (MHI) is prepared to take a further shot at its HTV-8 mission to provide supplies and other payloads to the International Space Station. The launch was initially scheduled for September 11, but the fire triggered a scrub and led to a subsequent investigation to decide the trigger. The new window is an instantaneous one particular set for 1:30 AM JST on September 24 (12:30 PM/ 9:30 PM ET/PT on September 23).
The investigation has now revealed that the fire, which was extinguished and resulted in no lasting harm to the rocket or its cargo, was most probably triggered by constructed-up static electrical energy produced by oxygen dripping from the exhaust for tof the rocket engine for the duration of propellant feeling. MHI has taken the actions needed to right for this challenge, and say that the rocket and launch facilities are now completely functional and prepared to go for this renewed launch try.
The H-IIB rocket employed for this launch (the configuration of MHI’s M-II series rocket that has the highest lift capacity) will carry supplies, as described, as effectively as a cubesat launcher with a quantity of compact satellite payloads for several academic and industrial prospects. The H-IIB options one particular central booster and engine with liquid oxygen propellant, and 4 strong fuel boosters attached to the base of the rocket for more lift. It can transfer up to 18,000 lbs to geostationary transfer orbit.
This is the second to final mission for the H-IIB, with its final mission planned for subsequent year. Following that, MHI has been difficult at perform on the H3, a completely expendable launch car at present below improvement that’s particularly aimed at serving additional industrial prospects with total launch expenses that are additional or significantly less on par with emerging competitors like SpaceX for medium heavy payloads.
