🏗️ One-Time Capital Costs
Total: $10.2B
Build cost for a small dedicated monitoring constellation (three interplanetary probes with science payloads optimized for SCP-5845 observation). Breakout: ~3 probes at ~$800M each (spacecraft bus, instruments, radiation hardening, magnetics payload).
Program-level uncertainty surcharge (20% of the above one-time subtotal) to cover cost growth, schedule slips, and unexpected technical challenges in interplanetary missions and novel sensor development. Applied after infeasible items were excluded per containment policy.
Multi-purpose probes/robotic assets for interior access attempts, acoustic imaging test payloads, and localized experimentation (small-scale argon injection capability, sample collection mechanisms).
Optional sample-return mission budget (design, ascent/transfer hardware, Earth reentry and curation) if O5 permission permits sample retrieval. Budget reflects a conservative small-sample return rather than bulk retrieval.
Development of precision Mercury lander/robotic emplacement hardware sized for payloads and surface instrumentation; thermal protection and mechanisms for high-insolation environment engineering.
Launch & transit insertion costs for the constellation (multiple heavy-launch + transfer stages aggregated; assumes partially reusable launch architecture and combined launch campaigns).
Feasible R&D: high-dynamic-impact capture simulation rigs, high-Δv docking/capture testing for non-relativistic extreme-speed objects, computational modeling of relativistic scenarios (non-prototyping), and development of doctrine for remote instrumentation on relativistic trajectories (proof-of-concept limited to simulation and surrogate testing). This is an achievable research line distinct from attempting true relativistic recovery.
One-time emergency reserve for unforeseen anomalous side-effects requiring rapid deployment of assets or emergency experiments.
Launch and transfer campaign specifically for lander emplacement missions (assumes rideshare and mission-optimized transfer windows).
Inspection and limited-intervention mission for the 10 km acrylic accessway (remote crawler/inspection payloads). Full-scale replacement is impractical and therefore not budgeted.
Terrestrial secure/black-site facilities, secure briefing centers, small hardened lab spaces and minor physical infrastructure for program oversight and classified meetings.
Ground control, comms uplink/downlink infrastructure, deep-space mission ops setup, and secure relay/telemetry systems dedicated to SCP monitoring.
Dedicated thermal protection system & materials development to survive Mercury approach, insertion, and surface operations; includes testing harnesses and prototype heatpipes/radiators.
Mission-specific operations, data reduction pipelines, and analysis infrastructure for robotic probe campaigns (mission planning, downlink analysis, post-processing).
Contingency pool for immediate mitigation actions identified by modeling (debris avoidance maneuvers for Foundation assets, rapid observation campaigns). This is an operational reserve, not compensation to external parties.
Initial procurement of general-use instrumentation, high-field magnetometers, standard remote-manipulator hardware, and lab benches not covered in specialized lab buildout.
Initial legal reserve for litigation preparedness, contractor protections, and classified contracting mechanisms.
Radiation-hardened, high-dynamic-range imagers and sensor suites sized for intense illumination environments; aggregated cost for multiple redundant sensor payloads (~4 payloads at ~$20M each).
Initial procurement of custom manipulators, vacuum-rated tooling, and anomalous-handling fabrication tooling sized for Mercury mission payloads and curation manipulations.
Baseline specialized materials analysis and non-destructive testing setup (muon tomography pre-arranged time, high-field probes, sample handling benches). Sample-return architecture and large synchrotron beamtime are budgeted separately if needed.
Initial, legally-plausible cover-story seeding and classified liaison expenditures. Note: large-scale concealment of certain signatures (e.g., major anomalous effects or obvious interplanetary signatures) may be impossible; this line covers limited diplomatic/administrative concealment efforts only.
End-of-life safe disposal and declassification/sterilization missions for expendable evidence assets and hardware.
Initial off-world archival placement costs and hardware for redundant storage of mission records and sensitive data (small deep-space/lunar store allocation).
Planetary environment and inner-solar-system debris trajectory modeling to estimate potential collateral risks from any high-energy events on Mercury.
A targeted, small-volume argon-injection experiment and corresponding acoustic imaging probes. Literal full-volume (multi-10^10 tonne) fills are infeasible and thus excluded; only small, localized injections are costed.
Small procurement budget for non-unique reagents, seals, or experimental containment reagents; truly exotic/anomalous reagent acquisition is unbounded and therefore not budgeted here.
Estimate set to 0 — the article's required capability to accelerate a human to 17–23% speed of light is non-physical for known Foundation non-anomalous infrastructure. Foundation does not budget for construction of practical relativistic delivery systems absent anomalous assistance. Realistic mitigation instead focuses on observation, remote robotic missions, simulation, and non-relativistic mission architectures (costed elsewhere).
Estimate set to 0 for attempts to recover objects traveling at ~0.2c; recovery at relativistic speeds is infeasible with non-anomalous technology. The Foundation budgets for non-relativistic high-speed capture simulation and testing (see hv_capture_simulation_and_nonrelativistic_r_d).
Estimate set to 0 — manufacture or procurement of a 4.5 gigaton 'thaumonuclear' explosive by non-anomalous means is effectively infeasible and unbounded under known physics and legal constraints. Foundation will not budget for literal manufacture. If anomalous means become available, separate approval & budgeting would be required; until then mitigation focuses on monitoring and lower-impact, feasible interventions.
🔄 Annual Recurring Costs

Operations, telemetry, data processing, and orbital maintenance for the monitoring constellation dedicated to SCP-5845 observation.
Ongoing research budgets: data analysis, modeling, instrument calibration, and ground-based study of mural imagery and material properties.
Salaries, benefits, hazard pay and classified premiums for program personnel (core scientific, engineering, ops, security, and program management staff).
Annual mission operations, data analysis, and health monitoring for active robotic probes and surface equipment.

Maintenance, utilities, and lifecycle refresh for terrestrial secure facilities and lab spaces supporting SCP-5845 work.
Ongoing legal support, limited disinformation maintenance, and diplomatic liaison expenditures. Does not assume successful large-scale concealment of major international signatures; intended for routine program-level cover operations.

Maintenance for off-world/archival storage and periodic redundancy checks.
Small recurring procurement budget for non-anomalous containment reagents or specialty parts; truly exotic reagents remain unbudgeted until obtaining anomalous assistance.

📋 Confidence Notes
This re-evaluation materially differs from the original Stage 2 estimate by excluding infeasible line items (relativistic propulsion, manufacture/use of a 4.5 Gt thaumonuclear device, and relativistic human recovery) and replacing them with achievable monitoring, robotic, and simulation programs. Numbers are conservative and itemized for all >$1B line items. Residual uncertainty remains due to mission-architecture risk, long lead times for interplanetary hardware, and potential future decisions to pursue anomalous-assisted options; where an item was judged impossible with non-anomalous technology it was explicitly zeroed and explained.
