## Summary
An orbital space station is a spacecraft designed for extended crewed presence in space that orbits a parent body, such as a planet. It serves as a permanent or semi-permanent human outpost in low Earth orbit, facilitating long-duration research and technology development.

## Key Facts
-   **Subclass of:** space station (a spacecraft designed to remain in space for an extended period with a crew).
-   **Primary Use:** orbital station-keeping (maintaining its specific orbit).
-   **Aliases:** orbital station.
-   **Google Knowledge Graph ID:** /g/121m7wm0.
-   **Encyclopædia Universalis ID:** stations-orbitales.
-   **Sitelink Count:** 1 (indicating limited direct coverage in some knowledge sources).
-   **Wikipedia Languages:** French (fr) is documented.

## FAQs
### Q: What exactly is an orbital space station?
A: An orbital space station is a specific type of space station designed to maintain a continuous orbit around a parent body, like Earth. It allows for human habitation in space for extended periods.

### Q: Why does an orbital space station need "orbital station-keeping"?
A: Orbital station-keeping is essential because small perturbations, like atmospheric drag and gravitational influences, gradually change a station's orbit. This process uses thrusters to maintain its intended trajectory and operational altitude.

### Q: What is the main purpose of having an orbital space station?
A: Its primary purpose is to provide a long-term platform for conducting scientific research in microgravity, testing space technologies, and enabling sustained human presence in orbit for international collaboration.

## Why It Matters
Orbital space stations represent humanity's most significant step towards becoming a multi-planetary species and a permanent off-world presence. They provide an unparalleled laboratory for scientific research, particularly in physics, biology, and materials science, where microgravity reveals phenomena impossible to study on Earth. Furthermore, they serve as essential testbeds for life support systems, spacecraft operations, and long-duration human spaceflight techniques crucial for future missions to the Moon, Mars, and beyond. They foster international cooperation and inspire generations, driving technological advancement and our understanding of living and working in space.

## Notable For
*   **Permanence in Orbit:** Designed for continuous, long-duration occupation within a stable orbital path around a celestial body.
*   **Continuous Human Presence:** Facilitates ongoing, crewed habitation in space for months or years at a time.
*   **Microgravity Research Hub:** Provides a unique environment for fundamental scientific experiments leveraging the absence of significant gravity.
*   **International Collaboration Platform:** Serves as a focal point for multinational space agencies and research partners.
*   **Orbital Operations Pioneering:** Requires and demonstrates complex orbital maneuvers like station-keeping to maintain its position.

## Body
### Classification
*   An orbital space station is a **subclass of space station**.
*   A **space station** is fundamentally defined as a spacecraft designed to remain in space for an extended period with a crew.
*   The distinguishing characteristic of an *orbital* space station is its **intended continuous orbit around a parent body**.

### Operations
*   A key operational requirement is **orbital station-keeping**, the use of propulsion to counter orbital decay and maintain a precise trajectory.
*   It is also known by the alias **orbital station**.

### Significance
*   The **Google Knowledge Graph ID (/g/121m7wm0)** and **Encyclopædia Universalis ID (stations-orbitales)** highlight its established recognition in knowledge bases.
