The struggle to perfect the second stage.
Mission Overview
Launched from Tanegashima, the first stage performed perfectly, but the second-stage engine failed to ignite for its second burn, leaving the satellite in a useless orbit.
Learning from History
"The failure provided critical data on the LE-5B-3 engine's ignition sequence in a vacuum, which was corrected for Flight 9."
