Five questions the
record has to answer.

Drawn from 5,548 unique records at abstract level; zero full texts were retrieved, which is stated as a limitation on every inference. Examines nutrient degradation, intake as the exposure term, and the energy-deficit confound in interpreting food-mediated outcomes.

Identified 217 analysable studies on crop response in altered and partial gravity. Replicate-level sample size was unclear in 175 of those 217, which bounds what the pooled record can support and sets the design requirements for a decision-grade crop investigation.

Identified 3,407 unique records, assessed 291, and analyzed 151 abstracts. Examines mass, volume, power, shelf life, and crew time as reported quantities, and documents how rarely the field publishes them on a comparable basis.

Assessed 39 records from 2,704 unique records; 6 named cost as an outcome. Examines procurement behavior, budget allocation, and why the field lacks a common price basis for comparing food-system options.

Includes 553 analysable studies from 965 assessed records and 5,382 unique records. Examines workload, sensory experience, mood, sleep, and cognition in isolated and confined environments, and what a short-duration protocol can measure without therapeutic claims.

Drawn from 2,434 unique records. Examines microbial composition, barrier integrity, and immune endpoints across spaceflight, ground-analog, and simulated conditions, and tests whether a literature reporting uniformly directional results can support a countermeasure inference.

Assessed 785 records and retained 388 analysable studies from 3,375 unique records. Examines which proposed SANS mechanisms carry causal rather than associative support, and how endpoint choice changes the value of a countermeasure study.

Identified 1,453 unique records, assessed 332, and extracted 205. Of the extracted records, 205, or 35 percent, changed evidence tier after methods review. Examines Nrf2 and antioxidant pathway evidence and the transfer question between simulated, analog, and flight conditions.

Identified 3,407 unique records, assessed 291, and analyzed 151 abstracts. Examines mass, volume, power, shelf life, and crew time as reported quantities, and documents how rarely the field publishes them on a comparable basis.

Retained 31 analysable studies from 5,758 unique records, of which 20 concerned planetary protection. Examines control points, traceability, containment, and approval pathways for a habitat that produces its own food.

Assessed 249 records and classified 150 as analysable from 5,111 unique records. Examines how chamber atmosphere, airflow, ethylene, and root-zone oxygen alter biological outcomes attributed to gravity, and what an experiment must measure to keep a crop result interpretable.
