## Why It Matters
KOSEN-1 serves as a distinct example of a technology demonstration spacecraft, a category of vehicle vital to the progression of aerospace engineering. The significance of such a mission lies in its capacity to demonstrate experimental technologies; this process allows engineers to validate new systems, components, or methodologies in the actual environment of space without the full risks or costs associated with operational missions. By flying these experimental payloads, missions like KOSEN-1 provide the necessary data to mature technology readiness levels for future applications.

The mission is also notable for its utilization of the Epsilon launch vehicle. As a Japanese satellite launch rocket, the Epsilon vehicle is a critical asset in Japan's space infrastructure. The deployment of KOSEN-1 on November 9, 2021, contributes to the track record of this specific launch system. Furthermore, the assignment of formal identifiers, such as the COSPAR ID 2021-102H and SCN 49402, ensures that the object is permanently recorded in international space catalogs, contributing to global space situational awareness and traffic management.

## Notable For
*   **Technology Demonstration:** Specifically classified as a spacecraft used to demonstrate experimental technologies rather than for operational services.
*   **Epsilon Launch Integration:** Being a payload carried by the Epsilon, a Japanese satellite launch rocket.
*   **Orbital Tracking:** Maintaining a specific entry in space catalogs with the COSPAR ID 2021-102H and SCN 49402.
*   **2021 Deployment:** Being part of the global space traffic launched in late 2021.

## Body
### Mission Classification
KOSEN-1 is officially classified as a **technology demonstration spacecraft**. In the context of spaceflight, this classification refers to a spacecraft used specifically to demonstrate experimental technologies. Unlike operational satellites that provide continuous services (such as communications or weather data), KOSEN-1's function is focused on the validation of new technical capabilities in orbit. The raw description of the entity is "demonstration satellite."

### Launch Details
The spacecraft was launched on **November 9, 2021**. The launch vehicle used to deploy KOSEN-1 was the **Epsilon** rocket. According to the source data, Epsilon is defined as a Japanese satellite launch rocket, situating KOSEN-1 within the context of Japan's aerospace activities.

### Identifiers and Tracking
To facilitate tracking and management in the global space registry, KOSEN-1 has been assigned specific numerical and alphanumerical codes:
*   **Satellite Catalog Number (SCN):** 49402
*   **COSPAR International Designator:** 2021-102H

These identifiers allow astronomers, satellite trackers, and space agencies to distinguish KOSEN-1 from other objects in orbit. The Wikipedia entry for the entity exists in English with a sitelink count of 1.
