H-IIA (H-2A) is a retired Japanese expendable launch system that was developed and operated by Mitsubishi Heavy Industries (MHI) in collaboration with JAXA. It was primarily used to launch satellites into geostationary orbit, interplanetary probes, and Earth observation missions. Notable payloads launched by the H-IIA include Akatsuki, a Venus climate orbiter, and the Emirates Mars Mission, which was launched toward Mars in July 2020. All launches were conducted from the Tanegashima Space Center.
