This is the event video:


Near the end there are 2 slides which is not available on the website, one show Rocket Lab Neutron style fairing/staging, another show SpaceX Startship Booster style landing.

Odd that the catcher for DECA appears to not be the launch mount? Also a bit of a tight fit as well.

The advantage is that if you fail to capture, you don't take out your launch site.

In addition to improving launch reliability, we will also improve MOMO for mass production and frequent launches, and demonstrate technology for the development of ZERO, which is scheduled to launch the first unit in 2023.

Has there been any update to this schedule? Zero still seems to be in a rather early stage of development and obviously won't launch in 2023.

This lot small LV compared to SS so lot easier to move around launch facility. SH is so large it really needs to be recovered next to launch pad.
While they've borrowed Neutron fairing design gone opposite path for vehicle recovery. RL traded simple pad for complex vehicle, Instellar complex pad for simple vehicle. Both have pros and cons.

At first glance the DECA catcher looks entirely passive though, making it pretty simple. There's no vertical trolley or chopstick arms, and possibly no horseshoe ring compensation (there might be something in the angled arms supporting the horseshoe ring, so the horseshoe might have a limited degree of freedom)

\ ZERO's prototype status, a little introduction /

The microsatellite launch vehicle "ZERO" currently under development by IST. A quick introduction to the prototype status of the tank to be mounted on the rocket 💁‍♂️

The photo shows the inner diameter holder. It is commonly known as "Uchibari-kun"!
It is used to reduce welding distortion in order to maintain a perfect circle when welding the outer circumference of the tank 👇

Japanís Interstellar aims for orbital launch in 2025 (Spacenews today)

Quote
Japanese launch startup Interstellar Technologies is preparing for a static fire test later this year that could pave the way for orbital launch of its Zero rocket in 2025.

Zero, a vehicle designed to send nearly one metric ton to low-Earth orbit ...

Preparing ... later ... could. This translates to a static fire (of what?) NET 2024 and a launch NET 2026-2027. But Zero has been upgraded from a micro to a small launcher. :-o

Intersteller Technologies  is conducting turbo pump tests with support from the Aioi Test Center of IHI.
This is a pretty big step forward for IST.

"Rocket ZERO's engine turbopump testing is now underway!
At the IHI AeroSpace AIOI Test Center, known for turbopump excellence, the IHI Group guides us. We've started cold flow tests with a non-reactive liquid nitrogen instead of liquid oxygen, achieving our designed RPM"

Press release 🚀
\

Rocket ZERO's propellant tank pressure test was successful!
At IST, we use aluminum alloy (A2219) for our tanks, which has high strength but requires advanced welding techniques, and performs the main processes from welding to testing in-house. Following the engine combustor unit test, this was an important development milestone.

Small satellite launch vehicle ZERO successfully conducts propellant tank pressure test

Interstellar Technologies Co., Ltd. (Headquarters: Taiki-cho, Hiroo-gun, Hokkaido; President and Representative Director: Takahiro Inagawa; hereinafter referred to as Interstellar Technologies) is a comprehensive space infrastructure company that aims to solve Earth's problems through space transportation and space utilization. We are pleased to announce that the propellant tank pressure test (main test) of the small satellite launch vehicle "ZERO" (hereinafter referred to as ZERO) was successfully conducted at the Interstellar Technologies Structural Test Building in Taiki-cho, Hokkaido. The final process of welding the propellant tank was carried out at the main factory, and it was confirmed that the strength as designed was achieved. Interstellar Technologies will steadily proceed with the design, manufacture, and testing of each component in preparation for the launch of the first ZERO.

Acquired aluminum welding technology that requires advanced technology

Interstellar Technologies designs all the propellant tanks in-house, which contain the fuel liquefied biomethane and the oxidizer liquid oxygen. The tank is made of aluminum alloy (A2219), which is strong but requires advanced welding techniques, and the main processes from welding to testing are carried out in-house.

This time, we manufactured a sub-scale model of the rocket's second stage tank (width 1700mm, height 1731.5mm, thickness 3.5mm), which was tested to ensure that it could withstand the designed pressure. We conducted a ``destructive test'' to see how much pressure it could withstand. In the future, we will proceed with the development and manufacture of actual models based on the data obtained from this test.

[Propellant tank pressure test overview]

Test name: Propellant tank pressure resistance/guarantee test, bursting pressure test, destructive test
Test purpose: To confirm whether the propellant tank has the strength as designed
Date and time: 2023 December 11th and 13th
Location: Interstellar Technologies Structural Test Building (Taiki-cho, Hokkaido)

Test results: Confirmed that it could withstand the designed test pressure, and obtained data on strength, failure mode, etc.

[Specifications of Rocket ZERO]

Total length: 32m
Diameter: 2.3m
Total weight: 71t
Propellant: Fuel Liquefied methane (liquefied biomethane), oxidizer Liquid oxygen
Number of engines: 1st stage 9, 2nd stage 1
Launching capacity: LEO 800kg / SSO 250kg *Future maximum capacity

Strengths include competitive prices and dedicated launches

ZERO is a small rocket targeting small-sized satellites that have been driving market expansion in recent years. Based on the knowledge gained from the observation rocket MOMO, which was the first privately operated independent rocket to reach space in Japan, we are proceeding with development with the aim of launching the first vehicle.

The space transportation services provided by ZERO are realized through an all-in-one development and manufacturing system, with a launch cost of less than 800 million yen per aircraft (at the time of mass production), a competitive price, and a diversifying satellite business model. Our strength lies in our flexibility, which allows us to launch exclusively for the event. For satellite operators in Japan and Asia/Oceania countries, we will provide the added value of ``convenience'' by being close to the launch site and requiring no effort or cost until the launch.

Increasing ZERO's capacity and establishing a position in the Asia/Oceania market

The weight of the small satellites targeted by ZERO is in the 100 to 200 kg range. In order to keep an eye on recent trends and capture strong domestic and international demand, ZERO will increase its capacity to a rocket capable of launching up to 800 kg of satellite weight into low earth orbit (LEO). Through this, we will meet the goals set forth in this project, contribute to building a self-sustaining domestic space transportation service, and establish a position in the Asian/Oceanian and European markets.
