On July 30, the Long March-8A carrier rocket is set for its first launch from No. 1 Pad at the Hainan commercial spacecraft launch site. As an upgraded version of the Long March-8, the 8A variant retains the original model's core first stage and boosters, while introducing an innovatively developed 3.35-meter-diameter universal hydrogen-oxygen upper stage and a 5.2-meter-diameter payload fairing.
