The fleet’s primary mechanism for putting payload on a surface without flying a vehicle down. Containers are produced and filled aboard the mothership, launched from the ventral drop bay, descend under interior gravimetric retro-fire, and are recovered by the transport ship for reload.
At a glance
- Form: modular sealed containers, four size classes, common locking and handle interfaces
- Size classes: small (1 m cube, up to 200 kg), medium (2 m by 1.5 m by 1.5 m, up to 800 kg), large (3 m by 2 m by 2 m, up to 2,500 kg), heavy (5 m by 2.5 m by 2.5 m, up to 6,000 kg)
- Propulsion: scaled-down field-coupled gravimetric retro-fire (interior; no visible engines, exhausts, or thrusters)
- Hull register: matte white-gray ceramic-composite (matches fleet)
- Accent system: dark accent panels with stencil tags color-coded per size class (small, medium, large, heavy)
- Power: compact fusion cell or battery pack sized to mission profile
- Beacon: continuous locator transponder
Capabilities
- Heat-shield underside for atmospheric entry
- Gravimetric retro-fire descent with mid-flight guidance correction
- Gentle vertical landing via gravimetric gradient cancellation (no exhaust scour)
- Standard locking interfaces compatible with rover, van, pickup truck, transport, and ship cargo systems
- Small, medium, and large containers stow on rover, pickup, and van roof racks for surface-side transport
- Recoverable and reusable: the transport ship lifts containers back to the mothership for reload
- Damaged hulls are recycled into raw stock by the manufacturing bay
Mission profile
A drop sequence runs from staged buffer to surface in minutes (low-orbit drops in roughly 4 to 8 minutes). Atlas-distributed computes descent trajectory, releases the container through a drop chute, and corrects mid-descent using telemetry. Nominal landing accuracy is within 50 m of pre-targeted coordinates; degraded conditions widen to 200 m. The container can re-target mid-descent if the original coordinate becomes unsafe, or be commanded to a holding orbit for re-drop.
Common use cases: forward-base shelter modules, science arrays and comms relays, sample return, rations and water and spare-parts resupply, emergency medical aid to a crew in distress, sister-ship cargo exchange, and replacement surface vehicles in heavy containers. Surface crew rendezvous via vehicle, on foot, or by treating the container itself as a marked staging point. Multiple shelter-module containers can be assembled into a forward base on site.
Drop cadence is one container every few minutes from staged buffer; sustained throughput is bounded by manufacturing-bay production (roughly one large container per hour from raw stock, faster for small). The drop bay can release several pre-staged containers in a simultaneous salvo.
Visual
Matte white-gray ceramic-composite hull matching the rest of the fleet. Dark accent panels frame the locking and handle interfaces. Stencil tags carry size-class color codes (small, medium, large, heavy) per the fleet’s color-craft tokens, readable at distance against Mars haze or lunar regolith. No visible engines, exhausts, or thrusters. Beacon lighting blinks during descent and after touchdown. Footprint at landing is roughly 1 m wider than the container itself; no scour ring, no scorch.
