This article does not say the reason of abortion. But I read somewhere saying that the SRBs failed to ignite.

JAXA and Mitsubishi Heavy Industries planned to debut the H3 launch vehicle early Friday. However, the launch was aborted at T0 when the main engine shut down before the Solid Rocket Boosters were to ignite. For its maiden flight, the rocket will launch the ALOS-3 optical satellite into a 669-kilometer Sun-synchronous orbit (SSO) from the Tanegashima Space Center in Japan.

Further addition of #1,009

If you (@SlothmanAllen) pay attention, SpaceX never said anything about the orbital parameter of these figures. That is the truth Elon does not want you to combine with the payload figures.
Thanks for the follow-up and figures Taxiya. Yeah, I don't trust Elon at all lol! I do think SpaceX has been pretty good about capabilities, but I do wonder if the Starship will ever really be viable.

Yes, Falcon 9 and Heavy are good capable rockets. Starship will be good too. No doubt.

but I do wonder if the Starship will ever really be viable.
Everything he could have achieved is viable because he never said anything concrete. He controls where the moving goal post would be set.

That is very important, especially with the changes in design and architecture that the rocket has seen so far.

Given the way SpaceX is known to develop and iterate, I am willing to bet that before - or if - this thing actually materializes as the Artemis lander and/or a viable commercial payload LV (seems to be a goal, at least), the goalposts will have moved....a lot!

In this context, arguing about capability and viability is...an exercise in futility since they control the narrative in what each should be at any given time.
Can't really set a firm point in moving sand, after all.

They already changed the propellant tanks from composite to stainless steel. The engines were also scaled down in size from initial expectations due to the whole rocket being scaled down. At this point it isn't the same rocket.
