Japan launched its flagship H3 rocket successfully from the Tanegashima Space Center.
This successful flight comes a few months after a previous mission failed in December because of an early shutdown of the second-stage engine.

The H3 rocket is a modern liquid-propellant launch vehicle created to take the place of the older H-IIA system.
Engineers designed it to be flexible, reliable, and affordable so that Japan can access space independently and win a bigger share of the commercial satellite launch market.

The Japan Aerospace Exploration Agency and Mitsubishi Heavy Industries worked together to build this heavy-lift vehicle.

The rocket cuts launch costs by about 50% compared to the older H-IIA model by using regular car parts bought off the shelf and 3D-printed hardware.
It uses a newly designed LE-9 first-stage engine that applies an advanced expander bleed cycle to keep thrust safe and efficient.
The modular design helps it carry big commercial telecom satellites, military navigation equipment, and heavy cargo payloads to the moon.
It can adjust its configuration by using zero, two, or four solid rocket boosters along with different payload fairing sizes to meet various mission needs.

SpaceX from the United States uses the Falcon 9, Falcon Heavy, and Starship, where the Falcon 9 competes directly with the H3.
India uses the LVM3 and PSLV through the Indian Space Research Organisation.
NASA in the United States relies on the SLS, while the European Space Agency flies the Ariane 6 and Vega-C.
China operates the Long March 5, and Russia relies on the Soyuz-2 and Angara A5 rockets.
