An H3 rocket successfully reached orbit and released two small observation satellites on Feb. 17 following a failed debut launch last year in which the second-stage engine did not ignite. The H3 is designed to carry larger payloads than the H-2A at about half its launch cost, or about 50 billion yen , to be globally competitive.
