CO2 enrichment significantly reduced NO3− content, partially supporting the hypothesis, but led to nutrient trade-offs, including increased Fe levels and reduced magnesium and Ca. Contrary to expectations, higher light intensity increased nitrate accumulation. A NASA-aligned crop suitability ranking identified low light intensity (230 μmol·m−2·s−1 PPFD) and CO2 enrichment (~1000 ppm) as the optimal conditions for enhancing space crop quality while mitigating dietary risks. These findings may inform NASA's space agriculture strategies for sustainable food production on long-duration missions and offer insights for controlled environment agriculture in resource-limited settings on Earth. ]]> ARTICLE <![CDATA[Optimizing an On-Demand Passive Fertigation System for Microgravity]]> https://sciendo.com/article/10.2478/gsr-2025-0006 https://sciendo.com/article/10.2478/gsr-2025-0006 Fri, 10 Oct 2025 00:00:00 GMT ARTICLE <![CDATA[Multimodal biofilm control strategies for spacecraft water systems: Evaluating coatings, nutrient removal, and biocides for improved sustainability]]> https://sciendo.com/article/10.2478/gsr-2025-0005 https://sciendo.com/article/10.2478/gsr-2025-0005 Sun, 14 Sep 2025 00:00:00 GMT ARTICLE <![CDATA[Impact of Simulated Microgravity Environment on Bioprinted Tissue Constructs]]> https://sciendo.com/article/10.2478/gsr-2025-0007 https://sciendo.com/article/10.2478/gsr-2025-0007 Tue, 09 Sep 2025 00:00:00 GMT ARTICLE <![CDATA[Performance and accuracy of the automated measurement software: Simple Online Automated Plant Phenomics (SOAPP)]]> https://sciendo.com/article/10.2478/gsr-2025-0004 https://sciendo.com/article/10.2478/gsr-2025-0004 Fri, 08 Aug 2025 00:00:00 GMT ARTICLE <![CDATA[Deep Cross-Organism Generalization of the Physiological Effects of Spaceflight from Mammalian Model Organisms to Humans]]> https://sciendo.com/article/10.2478/gsr-2025-0003 https://sciendo.com/article/10.2478/gsr-2025-0003 Wed, 02 Jul 2025 00:00:00 GMT ARTICLE <![CDATA[Japanese Oblate Film as a Novel Method for Seed Handling and Activation in Microgravity]]> https://sciendo.com/article/10.2478/gsr-2025-0002 https://sciendo.com/article/10.2478/gsr-2025-0002 Wed, 16 Apr 2025 00:00:00 GMT ARTICLE <![CDATA[Colloidal molecules in microgravity assembled by critical Casimir forces]]> https://sciendo.com/article/10.2478/gsr-2025-0001 https://sciendo.com/article/10.2478/gsr-2025-0001 Fri, 14 Mar 2025 00:00:00 GMT ARTICLE <![CDATA[Cultivating Sporeless Pleurotus ostreatus (Pearl Oyster) Mushrooms on Alternative Space-Based Substrates under Elevated Carbon Dioxide]]> https://sciendo.com/article/10.2478/gsr-2024-0014 https://sciendo.com/article/10.2478/gsr-2024-0014 Fri, 24 Jan 2025 00:00:00 GMT ARTICLE <![CDATA[Influence of hypergravity on root growth phenotype and physio-biochemical parameters in sorghum (Sorghum bicolor L.)]]> https://sciendo.com/article/10.2478/gsr-2024-0013 https://sciendo.com/article/10.2478/gsr-2024-0013 Tue, 31 Dec 2024 00:00:00 GMT ARTICLE <![CDATA[Agent-based model for microbial populations exposed to radiation (AMMPER) simulates yeast growth for deep-space experiments]]> https://sciendo.com/article/10.2478/gsr-2024-0012 https://sciendo.com/article/10.2478/gsr-2024-0012 Sat, 23 Nov 2024 00:00:00 GMT ARTICLE <![CDATA[Transport Phenomena Research in Microgravity via the ISS National Lab to Benefit Life on Earth]]> https://sciendo.com/article/10.2478/gsr-2024-0010 https://sciendo.com/article/10.2478/gsr-2024-0010 Sun, 10 Nov 2024 00:00:00 GMT ARTICLE <![CDATA[Multiphase Flow Regime Identification in Cryogenic Nitrogen using Electrical Capacitance Measurement Technology]]> https://sciendo.com/article/10.2478/gsr-2024-0011 https://sciendo.com/article/10.2478/gsr-2024-0011 Sat, 14 Sep 2024 00:00:00 GMT ARTICLE <![CDATA[USB Triggering of Video Recording in Sub-orbital Experiments]]> https://sciendo.com/article/10.2478/gsr-2024-0009 https://sciendo.com/article/10.2478/gsr-2024-0009 Fri, 16 Aug 2024 00:00:00 GMT ARTICLE <![CDATA[Formation of three-dimensional (3D) Self-Assembled Clusters of Anisotropic Janus Particles in Microgravity]]> https://sciendo.com/article/10.2478/gsr-2024-0008 https://sciendo.com/article/10.2478/gsr-2024-0008 Fri, 16 Aug 2024 00:00:00 GMT ARTICLE <![CDATA[Quantitative Measurements of Hazardous Gas Effluents from the Combustion of Crew Waste Simulant in Microgravity]]> https://sciendo.com/article/10.2478/gsr-2024-0007 https://sciendo.com/article/10.2478/gsr-2024-0007 Thu, 15 Aug 2024 00:00:00 GMT ARTICLE <![CDATA[Impact of payload shielding on Enterobacter cloacae viability and proteomic profile: Insights from a stratospheric weather balloon flight experiment]]> https://sciendo.com/article/10.2478/gsr-2024-0005 https://sciendo.com/article/10.2478/gsr-2024-0005 Sun, 09 Jun 2024 00:00:00 GMT ARTICLE <![CDATA[Seed Priming with Ulva lactuca L. in Cultivars Grown in Martian and Lunar Regolith Analogues]]> https://sciendo.com/article/10.2478/gsr-2024-0006 https://sciendo.com/article/10.2478/gsr-2024-0006 Sun, 09 Jun 2024 00:00:00 GMT ARTICLE
