Japan’s H2A rocket retired after successful final launch

Japan’s flagship H2A rocket lifted off for the final time at 1:33 a.m. on Sunday from the Tanegashima Space Center in Kagoshima Prefecture, successfully concluding a 24-year run that has defined the nation’s space capabilities.

The rocket’s 50th and final mission carrieds the GOSAT-GW, a government-developed hybrid environmental observation satellite. The satellite combines the Advanced Microwave Scanning Radiometer for monitoring ocean surface temperatures and water cycle dynamics with the TANSO sensor, which measures greenhouse gases, and is expected to play a key role in the country’s climate change mitigation and resource management.

With this final launch, the H2A retires with a stellar track record — 49 successful launches out of 50, a success rate of 98%. Jointly developed by Mitsubishi Heavy Industries and the Japan Aerospace Exploration Agency (JAXA), the 53-meter rocket debuted in 2001 and quickly became the workhorse of the country’s space program.
