The Business Case Begins with Numbers the Field Rarely Reports

A commercial case for transparent resource accounting

A defensible business case for an exploration food system begins when customers can see what it delivers and what it consumes. The reviewed evidence does not show that growing food costs less than carrying it. A credible comparison needs both resource burden and service contribution on a boundary that customers and investors can examine, preserve, and carry into the next decision.

Gastronaut’s design objective is to make transparent resource accounting part of ORCA’s development. The business interpretation is that such a record may create commercial value before a final architecture trade is settled. It exposes uncertainty, makes milestones testable, and allows weak configurations to stop before consuming a more expensive mission opportunity. This is an argument for responsible measurement, not a forecast.

This report makes no revenue, procurement, adoption, or return-on-investment forecast. The source set lacks the market and cost data required for those claims.

What the evidence says about the business case

Gastronaut’s frozen food-system engineering synthesis identified 3,407 unique records, assessed 291, and analyzed 151 abstracts. Twenty-nine, or 19.2 percent, supplied a number for at least one system-cost currency. Seven quantified two or more currencies in the same record. Six, or 4.0 percent, traded currencies on a common basis (Gastronaut).

Correcting the intervention coding left the FSY T4-versus-T2 comparison null (Fisher p = 0.100). The review does not show a significant tier collapse (Gastronaut).

The distribution matters. The 14 human-spaceflight records did not quantify what the food system cost to fly. Four of 13 non-human actual-flight food-system records reported a cost currency, as did sixteen of 64 modeled records. Figures needed for an architecture decision tend to live in models, while the highest-relevance human operations record contains limited comparable accounting (Gastronaut).

The workset has known limits. The frozen synthesis retrieved no full texts. A screening rule excluded at least 19 records containing “equivalent system mass,” while 39 more remained in an awaiting-classification backlog. The 19.2 percent figure is a floor for the analyzed workset, not a prevalence estimate for the literature (Gastronaut).

Within that boundary, the pattern can still inform decisions. Cost is often named and less often measured. Crew time appears in 23 abstracts and is quantified in three. Power appears as a number in one model. Two abstracts name in-situ production and resupply together but supply no comparative values. Filling these fields would answer a documented decision gap instead of adding another unbounded claim.

Four records illustrate usable fields. Zeidler et al. report 694.5 crew-member hours and 6.31 crew-member hours per kilogram of edible biomass for the 2019 EDEN ISS phase, with on-site time about four times remote support. Waters et al. resolve modeled food-system equivalent system mass among equipment, crew labor, and power and cooling. Hunter, Emanuel, and Drysdale name a comparison across food waste, preparation and cleanup labor, and water use, although its values were not in the abstract. Leach and Ewert use 878 days of International Space Station manifests to keep food mass beside other logistics categories. Each record contributes part of an accountable comparison. None supplies the complete business case.

Decision value before cost advantage

A customer evaluating ORCA needs to know which service the system provides and which resources it consumes. A comparison might include edible output, nutrient contribution, accepted servings, food availability, atmosphere interaction, crew time, power, water, consumables, maintenance, waste, volume, and mass. Every quantity needs a boundary, duration, uncertainty, and baseline.

Investor diligence uses a related record for a different choice. It asks whether development capital is reducing a technical uncertainty that matters to a future customer. A campaign that stabilizes a resource ledger, identifies a dominant cost driver, narrows a crew-time distribution, or retires a failure mode can inform diligence even while the architecture remains precompetitive.

One campaign result can therefore serve two decisions without merging them. NASA may use the result to judge readiness for an analog or integration study. An investor may ask whether the next tranche is buying evidence or extending an assumption. A shared record preserves continuity; separate duties preserve judgment.

Four evidence products

ORCA development can produce four evidence packages. Their order follows the questions that a later comparison will need to answer.

Resource baseline

The resource baseline would measure mass, volume, power, heat, water, gases, nutrients, consumables, waste, scheduled and unscheduled labor, remote support, maintenance, and replacement in a defined ground configuration. Native measurements would remain beside any equivalent-system-mass conversion.

Service baseline

Set beside those inputs, the service record would report edible and inedible biomass, accepted servings, consumed fraction where measured, crop mix, days of availability, quality criteria, losses, and any credited environmental service. Each resource number would remain attached to the output it purchased.

Fault and recovery package

A prespecified campaign would supply fault and recovery evidence by recording detection, safe state, crew and remote intervention, repair, consumables used, retained biological material, recovery time, and restored service. An unfavorable result would reveal the configuration’s present limit while the hardware remains accessible and the cost of learning remains bounded.

Comparative trade package

The final package would place a bounded ORCA service beside a declared stored-food or alternative-production baseline for one mission segment. Parameter sources, accounting coefficients, and sensitivity cases would remain visible. If NASA changes a mission assumption, the trade could be rerun without discarding the underlying measurements.

Milestones that govern capital

Capital release can follow evidence transitions rather than calendar progress. First come repeatable resource and service baselines. The program then identifies the variables responsible for most uncertainty and tests observation and recovery for a bounded fault set. Later stages reproduce performance across configurations or operating periods, complete a common-basis comparison against the selected alternative, and test whether ground-derived relationships transfer to an analog or flight environment.

Each milestone can carry advance, redesign, and stop conditions. Technical risk will not necessarily decline at every step. The structure identifies when it has declined and preserves the decision value of finding when it has not. The next commitment then inherits evidence rather than expectation.

The counterargument

A measurement standard adds burden before market demand is settled. The trade is real: instrumentation, logging, data curation, and analysis consume time and capital. Excess measurement can also distract from hardware maturation.

The evidence supports a bounded response. The campaign can measure the currencies that control the next decision, use a shared schema, and stop collecting fields with no declared use. The aim is enough provenance to distinguish an engineering improvement from a boundary change, not maximal data. Stewardship applies to measurement burden as well as to mission resources.

NASA also has equivalent-system-mass methods already. Those methods are necessary, but the review found that modeled studies often lack visible parameter lineage and cannot be collapsed into independent estimates. Gastronaut’s role would be to supply measured ORCA inputs and an auditable chain into the selected NASA method, not to replace it.

A grounded company position

ORCA remains a ground-stage system at approximately TRL 3 to 4, with no flight or lunar operating history. Its present value proposition is a design objective supported by a measurement plan. Gastronaut’s internal operating record can inform the baseline; it does not establish flight performance, reliability, economic advantage, or crew-health benefit.

Confidence is high that transparent resource accounting will improve the interpretability of ORCA development milestones. That finding can guide work now. Confidence is low regarding the eventual cost relationship among ORCA, stored food, and other cultivation architectures; that relationship requires a common-basis campaign. The expected commercial value of clearer milestones is a design interpretation, not a result established by the reviewed studies.

The business case begins when Gastronaut can show what ORCA used, delivered, lost, and recovered, then identify which uncertainty changed. NASA can use that record to make a technology decision about evidence readiness. Investors can use it to decide whether another stage of capital is purchasing evidence against a material uncertainty. The record is held in common; the responsibilities and decisions remain distinct.
