## Why It Matters
OPUSAT-II represents a specific entry in the modern era of small satellite deployment. As a CubeSat, it embodies the shift toward miniaturized space technology, allowing for more cost-effective access to orbit compared to traditional larger satellites. Its launch aboard the Antares rocket connects it to a significant lineage of commercial and logistical launch operations managed by Northrop Grumman. The existence of OPUSAT-II highlights the continued expansion of objects in Low Earth Orbit, evidenced by its assignment to the extensive 1998-067 launch group (indicated by its COSPAR ID suffix SG). By utilizing standardized cubic modules, satellites like OPUSAT-II demonstrate the utility of modular design in space exploration and data collection.

## Notable For
*   **Standardized Design:** Being a CubeSat, it utilizes the industry-standard 10 cm cubic form factor.
*   **Launch Grouping:** Its COSPAR ID (1998-067SG) places it within a specific sequence of objects launched, often associated with deployments from the International Space Station or similar aggregate launches.
*   **Launch Platform:** It is a payload of the Antares launch system.

## Body
### Technical Classification
OPUSAT-II is structurally defined as a **CubeSat**. This classification refers to a category of miniaturized satellites that are made up of one or more cubic modules, each side measuring exactly 10 cm. The CubeSat standard facilitates the launch and deployment of small payloads.

### Launch and Deployment
The satellite was launched on **February 20, 2021**. The launch was facilitated by the **Antares** rocket system. Antares is a medium-class launch vehicle manufactured in the United States by Northrop Grumman, capable of delivering payloads to orbit.

### Orbital Identification
For tracking and cataloging purposes, OPUSAT-II is identified by two specific international codes:
*   **COSPAR International Designator:** 1998-067SG
*   **Satellite Catalog Number (SCN):** 47930
