General
i-Space (a.k.a Space Honor, Interstellar Glory, StarCraft Glory) has sketched out its vision for the Hyperbola-9 launch vehicle, which is intended for missions to the Moon, Mars, and deep space.

– Diameter: 11m
– Takeoff thrust: 7,000 tons
– 1st stage powered by 33 300-ton LOX/Methane engines
– Capacity to LEO: 100 tons
– Capacity to LTO: 50 tons

Really? I personally believe that LM-9 would be pretty important to establishing a larger manned presence in space and the moon, could be really helpful to launch large prefabbed lunar base parts along with their associated ancillaries for the near future and theoretically it should be cheaper than multiple launches via a smaller rocket like the LM-10A. I feel like nuclear tug like the Zeus still is at least a decade or two away from being fully operational same with nuclear upper stages and China planned their lunar base to be finished by 2035, plus Zeus almost definitely isn't human rated and seems to be limited by Angara-5's carrying capacity while a LM-9 could carry a much larger human rated tug to space for orbital assembly for cheap and fast, practical mass transport to Mars for when they establish a presence on Mars in the 2040s.

I have to agree that LM-9 has a special usefulness.

As others here have alluded to, there is a qualitative [not just quantitative] benefit to large, heavy-lift rockets.

Yes, you can assemble in orbit or on the lunar surface smaller components from medium-lift rockets.

But after reading some astronautics history, I learned that engineers like to launch key, large components that have been ground-tested. Something like the core module of a new space station, or the hub of a lunar installation. You want to have the whole component ground-tested, and then launched as one.

It's just better from a testing and verification standpoint. Yes, this does not justify large-lift for most countries. For China, with lunar and space-station ambitions, it is a useful capability.

ArrowHead/Space Epoch has successfully conducted its first VTVL test. The VTVL test vehicle is a stainless steel rocket with a diameter of 4.2m, a length of 26.8m, and a take-off mass of 57 tons. The test lasted 125 seconds, during which the vehicle reached an altitude of 2.5km before performing a soft splashdown landing in the water. The vehicle successively performed eight tasks: ignition and takeoff, full thrust climb, variable thrust adjustments, engine shutdown, free descent glide, engine restart, deceleration to hover on sea surface, and finally soft landing on the sea surface.

Oh dear. Well done. Why they didnt try to land it on a surface sea platform ? I think they would have suceeded in doing so smoothly.
Anyway this is a great achievement. Will be good to see their next test if they will try and do even better.
