PRESS RELEASE
Dec, 2020
Interstellar Technologies Inc.

Rocket Development Startup “Interstellar Technologies,” to Establish
a New Company, “Our stars Inc.” , Entering the Satellite Business Field.
To expand into three businesses: Innovative communication satellites, Earth observation
satellites, and Space experiment satellites with recovery capsules.

Obihiro, Hokkaido - Tuesday, December 25, 2020
Interstellar Technologies Inc（Memu Taiki Town Hokkaido, JAPAN, CEO: Takahiro Inagawa, hereinafter referred toas “IST” ） is a rocket development startup with a mission to “create a future where everyone can reach space.” IST
is pleased to announce that it will establish a subsidiary company, Our stars Inc ( hereinafter referred to as “Ourstars”), and enter the satellite business in early 2021.
IST has been developing the sounding rocket “MOMO” and the small-satellite launch vehicle “ZERO” under theproduct concept of “the worldʼs most affordable and convenient launch vehicle. In recent years, rocket development
companies worldwide have been using their rockets to develop new satellite projects. The emergence of a verticallyintegrated business model in which rocket development companies use their vehicles to launch their satellites hasbrought a significant revolution in the space industry.

Company name: Our stars Inc.
Establishment date : Early 2021
Executive officers : Takafumi Horie (President), Takahiro Inagawa (Officer)
Business activities : Proposing business using satellites and other technologies
Research & development, manufacturing, and operation of satellites
l Capital: Established as a wholly-owned subsidiary of IST.

Bring a signiﬁcant revolution by a vertically integrating rocket and satellite.
Conventional space utilization includes three fields: "Satellite Communications" such as satellite telephony andBS/CS broadcasting, "Earth Observation (remote sensing)" represented by meteorological observation andinformation gathering satellites, and "Space Experiments" on the ISS (International Space Station). Together with
"Our stars," IST will bring technological innovation to the three fields of space utilization by combining small rockets
and small satellites with building a platform in space. One of the advantages of a rocket development company
providing satellite services is that it can optimize both the rocket and the satellite, for example, by customizing thevehicle to meet the satellite's specifications, thus providing end users with cheaper, faster, and more convenientservices.
The three main advantages of rocket development companies also developing services utilizing satellites are as
follows.
Ø Reasonable
By developing satellites optimized for "ZERO," we can reduce the satellite structure's margin and separation parts.
As a result, we can achieve lower service fees for end-users.
Ø Speedy
Satellite constellations require a long time to place the satellite into orbit. By providing a one-stop service for bothlaunch vehicles and satellites, we can secure launch vehicle production and launch opportunities according to plan,thus enabling the early construction of a satellite constellation.
Ø Precise
Small rockets are suitable for delivering satellites with pinpoint accuracy to specific satellite orbits such as low orbit(150km~200km). By integrating the service with the launch vehicle, we can precisely deliver satellites to the desired
trajectory.

ServiceService 1

Communication satellite service using
nano-satellite auto-formation flights

Thousands of nano-satellites the size of ping-pong balls will orbit in a desiredformation. Each satellite cooperates with the others to function as a largeantenna, achieving communication performance superior to large satellites.
This service will create a communication network that enables satellite
communication even from small antennas on the ground. The overall function
will be maintained even if some satellites break down since the antennaconsists of hundreds and thousands of satellites.

Service 2

Earth Observation Service by Very Low
Altitude Remote Sensing Satellites

Nano-satellite orbits at a very low altitude (150km~200km) to observe theEarth's surface. Since it orbits at a very low altitude, it can take high-resolution
photographs. Conventional high-resolution (less than 1m) satellites are highperformance and expensive, but Japanese space agencies have alreadydeveloped high-resolution and very-low-altitude satellites. Integration with thelaunch vehicle is key to delivering the satellite to the specific orbit of very low
altitude and is one of our company's strengths as a rocket company.

Service 3

Providing opportunities for Space experiments(zero-gravity experiments) in the post-ISS era.
Space Experiment Satellite + Recovery CapsuleWith a weight of around 100 kg, the satellite will provide a zero-gravity
environment for future experiments in space with our space experimentsatellites. The ISS (International Space Station) will be reviewed for future
operations by 2024, and we will provide a zero-gravity environment for future
experiments in space with our space experiment satellites. We will make spaceexperiments even more accessible by enabling early and frequent experiments.
