Note 1: Launch was aborted. Per early announcement, the main engines lit up but the solid rocket boosters failed to fire.
Note 2: New attempt 18.02.2023, 01:37 UTC
It is the first rocket to use an expander bleed cycle.
Propellants for the first and second stage are liquid hydrogen as fuel and liquid oxygen as oxidizer. Depending on the configuration, the first stage can have either 2 or 3 engines. Additionally there can be 0, 2 or 4 solid rocket boosters attached to the first stage.
On this flight, the rocket will fly in the H3-22 configuration. That means 2 main engines plus 2 solid rocket boosters.
The H3-30 version is estimated to cost $50 million for a 4000 kg capacity to a sun-synchronous orbit.
This mission will carry a payload mass of 3000 kg into a sun-synchronous orbit. The payload is the Advanced Land Observation Satellite (ALOS).
