Another japanese newspace startup is making waves with their air augmented tripropellant SSTO spaceplane with P2P. Definitely reaching for the stars here.

Seems like IHI Aerospace and MHI are lending some help. Actively poaching talent from other japanese space startups as well.


Seems they are involved with Space Transit, another company

whose big thing is ATREX, a JAXA sponsored airbeathing LACE style engine similar to the Skylon SABRE. I suspect they are the engine supplier?

ASCA is a single-stage-to-orbit vehicle (reusable rocket) being developed by ISC.
The company aims to gradually implement services starting in 2028, with development being fast and flexibly responsive to market needs through its unique agile structure.

Once a day, Capable of over 1,000 repeat flights
With a turnaround capability of once a day, and with detailed inspection, maintenance and replacement, the aircraft and propulsion system can fly repeatedly more than 1,000 times.

High payload delivery capability
Capable of launching a 10-ton payload into Earth orbit (altitude of about 400 km)

For daily transportation
Capacity is 50 people, with the same reliability and safety as an aircraft

First Launch: Early 2040s
Total Length: 40.7 m
Diameter: 8.1 m
Dry Mass: 81 tons
Gross Mass: 716 tons

It also states that ASCA 1.0 hopper will launch by end of 2025.

Yet another spaceplane concept that won't come to fruition. Humans can't into space planes.

Seems like they effectively have given up on their air breather tripropellent SSTO dreams and pivoted to Falcon 9 clone mode. A hoppper testing reusable booster designs, a possible second stage swap for a suborbital spaceplane.

The interesting thing here Is Ursa Major and their Hadley rocket engine squeaking into the hopper, possibly the Falcon 9 clone.

I would love to buy some Ursa Major stock if it was available.
