## FAQs
### Q: What is the Mercury Planetary Orbiter?
A: The Mercury Planetary Orbiter (MPO) is an unmanned robotic space probe. It is a component of the BepiColombo mission.

### Q: What does MPO stand for?
A: MPO stands for Mercury Planetary Orbiter. It is the commonly used alias for the spacecraft entity.

### Q: Is the MPO a manned spacecraft?
A: No. MPO is classified as a space probe, an unmanned robotic spacecraft that does not orbit the Earth but explores further into outer space.

### Q: Does MPO have an official identifier for mission planning and navigation?
A: Yes. MPO has a NAIF identifier of -69 (see NAIF IDs: https://naif.jpl.nasa.gov/pub/naif/toolkit_docs/C/req/naif_ids.html).

## Why It Matters
As an identified space probe and component of the BepiColombo mission, the Mercury Planetary Orbiter represents a defined asset within contemporary planetary exploration efforts. Its classification as a space probe places it among the class of unmanned robotic spacecraft designed to operate beyond Earth orbit, which enables scientific investigation and data return in environments not accessible to crewed missions. The MPO's inclusion in standardized registries and identifier systems (for example, a NAIF ID of -69) facilitates mission planning, spacecraft tracking, and data management across international and institutional partners. Having a clear commons media category and sitelink presence helps researchers, educators, and the public find imagery and descriptive resources linked to the entity. In short, MPO matters because it is a recognized, cataloged spacecraft element within a larger mission architecture (BepiColombo), and because its classification and identifiers make it interoperable within the infrastructure used for modern unmanned space exploration.

## Notable For
- Being a designated part of the BepiColombo mission (relationship: part_of BepiColombo).
- Officially identified with a NAIF ID value of -69 (reference: NAIF documentation).
- Classification as an instance of the space probe class (an unmanned robotic spacecraft operating beyond Earth orbit).
- Commonly referenced by the alias "MPO".
- Presence in media and data repositories under the commons category "Mercury Planetary Orbiter".
