Real-Time Nutrient and Water Monitoring Systems in Space

Active TRL 4 (started at 4, targeting 6)

Description

FLEW.ID is a revolutionary real-time water and nutrient monitoring system that uses laser-induced breakdown spectroscopy (LIBS) technology to analyze liquid samples instantly. It uses laser light to identify the exact chemical makeup of water or nutrient solutions in less than one second.

The system works by directing a focused laser pulse into flowing liquid, creating a tiny plasma spark that breaks down molecules into their basic elements. This plasma emits light in specific colors that act like chemical fingerprints, allowing sensors to identify and measure nutrients, contaminants, and other substances with laboratory-grade precision. Unlike traditional testing methods that require sending samples to labs and waiting days or weeks for results, FLEW.ID provides instant, continuous monitoring without consuming any chemicals or creating waste.

The technology delivers unprecedented accuracy (detecting substances as low as 10 parts per million) while being 100 times faster than current gold-standard laboratory methods and 10 times more cost-effective per sample. Most importantly, it operates completely autonomously, requiring no human intervention or consumable materials — making it ideal for always-on life-support systems.

Problem Statement 
Current water and nutrient monitoring relies on manual sampling and Earth-based laboratory analysis, which creates critical bottlenecks for space missions. When astronauts need to know if their water is safe to drink or if their food-growing systems have the right nutrients, they currently must collect samples, store them, and wait for analysis back on Earth — a process that can take weeks and provides no real-time feedback for critical adjustments.

This approach is not only impractical for long-duration missions to Mars or lunar bases, but it also fails to provide the immediate, continuous monitoring needed for closed-loop life support systems where small problems can quickly escalate. Additionally, existing methods like inductively coupled plasma mass spectrometry are expensive, require trained technicians, consume significant resources, and cannot easily operate in microgravity environments.

FLEW.ID solves these problems by providing:
• Instant Results: Detection and analysis in under one second versus weeks for traditional methods
• Zero Consumables: No chemicals, reagents, or disposable materials needed
• Autonomous Operation: Requires no human intervention or specialized training
• Continuous Monitoring: Provides 24/7 real-time data for immediate decision-making
• Cost Effectiveness: Reduces per-sample costs by 90% while eliminating transportation and storage expenses 

Technology Maturation 
Flight Opportunities' parabolic flight tests will be crucial for advancing FLEW.ID from TRL 4 to TRL 6, representing the critical transition from laboratory prototype to space-ready system. These microgravity tests will validate three essential aspects of the technology:

Fluid Dynamics Validation: In microgravity, liquids behave differently than on Earth, potentially forming bubbles or behaving unpredictably. These flight tests will ensure the laser can accurately target flowing liquids and maintain precise measurements regardless of gravitational conditions.

Bubble Formation Analysis: Air bubbles in the liquid could interfere with laser accuracy. The flights will test bubble mitigation strategies and confirm that the system maintains precision even when bubbles are present.

LIBS Accuracy Verification: The plasma formation process at the heart of this technology needs validation in space conditions to ensure the same chemical detection accuracy achieved on Earth.

Expected Post-Flight Outcomes:
• Comprehensive performance dataset proving space readiness
• Optimized system parameters for microgravity operation
• Validated integration protocols for International Space Station and future lunar habitats
• Technology demonstration package ready for orbital missions
• Commercial readiness for terrestrial applications, accelerating market entry

Benefits

NASA Funded and Unfunded Missions FLEW.ID directly addresses four critical NASA strategic technology gaps:

How to get involved

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
