Dragonfly Scout Drone
Category: [TECHNOLOGY]
Type: [Robotic Probe, Prospecting Equipment]
1. Summary
The Dragonfly Scout Drone is a small, 4-tonne ion-drive powered minisatellite used extensively in the Terran Sphere for close-up asteroid prospecting and preliminary resource assessment. Deployed individually or in small swarms, Dragonflies perform “dip-pass” or “touch-and-go” maneuvers on targeted asteroids, utilizing a suite of onboard sensors to gather detailed geological and compositional data. This data, critical for identifying viable mining targets, is then transmitted back to survey bases or processing cores under strict low-bandwidth, Wildcode-safe protocols.

Relevant Equations/Relationships:
- The $\Delta v$ of $3.5 \, \text{km s}^{-1}$ defines the drone’s operational range and ability to maneuver between multiple targets or make significant orbital adjustments during its sortie.
- The $2 \, \text{Gb s}^{-1}$ data link, while relatively slow for large datasets, is a deliberate constraint to remain well below the Wildcode infection threshold. This necessitates onboard data compression and prioritized, batched transmissions or physical data retrieval.
3. Narrative Detail & Context
Before committing the immense resources required to capture and process an asteroid, detailed on-site information is crucial. While telescopic spectro-surveys provide initial broad classifications, the Dragonfly Scout Drone is the workhorse for obtaining ground-truth data. These nimble probes are essential for the first phase of the [Belt Mining Workflow].
Mission Profile & Operation:
Dragonflies are typically deployed from larger survey ships or orbital depots near asteroid fields like the Main Belt or Jupiter Trojans.
- Target Approach: Using its efficient ion drive, a Dragonfly navigates to a pre-selected asteroid target identified by long-range surveys. The $3.5 \, \text{km s}^{-1}$ $\Delta v$ budget allows for several such encounters or extended loitering time per sortie.
- Dip-Pass / Touch-and-Go: The drone executes a series of close flybys or brief “touch-and-go” landings (if the asteroid’s gravity and surface conditions permit). During these passes:
- LIDAR maps the asteroid’s exact shape, size, and surface topography, creating a detailed 3D model.
- The Neutron Spectrometer “sniffs” for hydrogen concentrations near the surface, a strong indicator of water ice.
- The Gamma-Ray Altimeter/Spectrometer measures natural gamma radiation from elements like Potassium, Thorium, and Uranium, helping to infer bulk composition and density. It also serves as a precise altimeter.
- The VNIR Hyperspectral Mapper analyzes reflected sunlight to identify specific minerals, organic compounds, and different types of ices on the surface.
- Data Management & Transmission: Due to [Wildcode Crisis] restrictions, continuous high-bandwidth data streaming is forbidden. Instead, the Dragonfly processes and compresses sensor data onboard using hardened, limited-compute processors. This “geology packet” is then either:
- Transmitted in short, low-bandwidth bursts ($ \leq 2 \, \text{Gb s}^{-1}$) to a relay satellite or directly to a base, often queued for transmission every 24 hours.
- Stored on a hardened crystal data rod, which might be physically retrieved by a “Shepherd” tug or a dedicated retrieval drone at the end of the Dragonfly’s sortie or at pre-arranged intervals. This physical transfer is often preferred for very large or sensitive datasets.
A typical sortie for a Dragonfly lasts around 180 days, after which it may return to a depot for refueling, maintenance, and data offload if physical retrieval is used.
“Used Future” Feel:
Dragonfly drones are utilitarian and robust. Their multi-layered insulation would be scuffed and possibly punctured by micrometeoroids after a long mission. Their sensor apertures would be meticulously clean but the chassis might bear witness to close encounters with dusty asteroid surfaces. They are tools, not characters, and are designed for endurance in a harsh environment. They are often deployed in small groups, their movements coordinated by a central mission control that prioritizes targets based on incoming data from long-range surveys and previously scouted asteroids.
4. Canon Hooks & Integration
- Initiator of Mining Operations: Dragonfly data is the first step in deciding whether an asteroid is worth the significant investment of capture and processing via systems like the [Spooler Net-Capture Tug] and [Spin-Gravity Drum Processor].
- Low-Bandwidth Operations: Their data handling methods highlight the ongoing impact of the Wildcode Crisis on even remote, automated systems.
- Exploration & Discovery: Dragonflies might be the first to identify asteroids with unusual compositions, unexpected resource concentrations, or even signs of prior (non-human) activity.
- Vulnerability: While agile, they are small and relatively unshielded. Solar flares, unexpected debris fields, or even minor malfunctions in their ion drives could lead to mission loss.
- Resource for Prospectors: Independent prospectors or small mining concerns might operate their own (perhaps older or less sophisticated) Dragonfly-equivalent drones.
Story Seeds:
- A Dragonfly scout transmits a garbled, incomplete data packet hinting at an incredibly valuable resource (or a dangerous anomaly) on a remote asteroid before going silent. A recovery mission is launched to retrieve its data rod and discover its fate.
- A rival corporation or pirate group attempts to “spoof” or intercept the low-bandwidth data transmissions from a competitor’s Dragonfly swarm to gain an advantage in claiming newly prospected asteroids.
-
A Dragonfly, during a “touch-and-go” maneuver on a supposedly inert C-type asteroid, accidentally activates a dormant, pre-Crash piece of technology (or even a [[Wildcode Crisis |
Wildcode Pocket]]) hidden beneath the regolith. |
- Due to a shortage of new Dragonfly drones, an old, unreliable unit is reactivated for a critical survey mission. Its aging systems and limited $\Delta v$ make the mission exceptionally challenging for its remote operators.
