Space Lab Technologies, LLC¶
Boulder CO. 6-year FO project — longest in this batch. Thin-film hydroponic plant cultivation for microgravity. Unusually diversified SBIR portfolio: food, life support, thermal control, and now lunar mineral mining (EcoMine).
Last updated: Session 76, 2026-04-07
Summary¶
Space Lab Technologies, LLC (Boulder, CO) is a small company with an exceptionally broad NASA SBIR portfolio spanning food production, life support hardware, thermal control, and — most recently — bioregenerative lunar mineral mining. The FO project 106694 is a 6-year parabolic flight program (2019–2025) validating thin-film hydroponic plant cultivation in microgravity using passive capillary processes, advancing TRL 4→6. PI Christine Escobar is a recognized space crops researcher. The LILYPOND Lab Test Suite was installed at a NASA facility in May 2025 ($96K contract), suggesting hardware is now in NASA hands for further evaluation. No ISS deployment confirmed.
The most notable finding is the company's 2024 pivot to EcoMine — bioregenerative mineral mining from lunar regolith — a $899.8K Phase II IGNITE contract that is architecturally distinct from hydroponics. This company is diversifying aggressively and may be outgrowing its original food-production identity.
Outcome category: Active SBIR Portfolio — FO project validates core hydroponics physics; LILYPOND hardware at NASA facility; no ISS hydroponic deployment confirmed. Company growing across multiple life support and ISRU domains.
Confidence: suggestive (SBIR portfolio confirmed; LILYPOND installation confirmed; ISS deployment unconfirmed; EcoMine Phase II confirmed)
Archetype: Committed long-term SBIR partner — diversifying from food production into ISRU
FO Project¶
| Field | Detail |
|---|---|
| Project ID | 106694 |
| Title | Microgravity Investigation for Thin Film Hydroponics |
| Period | 2019-01-01 – 2025-12-31 |
| TRL | 4→6 |
| TX area | TX06.3.5: Food Production |
| PI | Christine Escobar |
| Co-Investigator | Adam Escobar |
Technology: Thin-film hydroponics grows plants in a thin liquid film on a substrate, relying on capillary forces rather than gravity to deliver water and nutrients to roots. In microgravity, conventional hydroponic systems fail because water does not drain predictably. Space Lab's approach uses passive capillary flow — no pumps, no powered fluid management — to maintain the thin film across the root zone regardless of gravity orientation.
Why 6 years: The 2019–2025 span is the longest FO project in this investigative batch. Thin-film hydroponics requires seasonal testing (different crops, different growth stages), repeated parabolic flights, and iterative hardware development. A 6-year commitment signals NASA's belief that the technology needed sustained validation, not a single flight test.
G-LILYPOND / UG-LILYPOND: Space Lab's floating plant pond systems. G-LILYPOND is a gravity-dependent variant; UG-LILYPOND (Ultra-G? Or microgravity?) is the microgravity-adapted version. The naming convention suggests an iterative design evolution through the FO program.
Christine Escobar (PI)¶
Christine Escobar is VP & Chief Business Officer of Space Lab Technologies and the PI for the microgravity LilyPond program. She is currently pursuing a PhD at the University of Colorado at Boulder on robust design of controlled ecological life support systems (CELSS) — her academic research directly feeds the company's technology development. The FO project specifically investigates duckweed (family Lemnaceae) as a space crop — a highly efficient aquatic plant requiring no soil or growing media, reducing mass, waste, and resupply needs.
Adam Escobar (co-I) is co-founder. The Escobar team has been pursuing space hydroponics consistently across the full 14+ year company history visible in USASpending. The company's team also includes Madison Jones (Mechanical Engineer), Pamela Flores (Post-Doctoral Research Assistant), and a collaboration with Colorado School of Mines (Dr. Jaeheon Lee) for the EcoMine work.
LILYPOND Lab Test Suite Installation (May 2025)¶
A $96.1K contract (80NSSC25PB067, 2025–2026) covers "Space Lab LILYPOND Laboratory Test Suite Shipping and Installation Included" — indicating that physical LILYPOND hardware was shipped to and installed at a NASA facility in mid-2025. This is a meaningful milestone: the hardware has moved from Space Lab's lab to NASA's lab. It suggests NASA is conducting independent evaluation or integration testing, which typically precedes an ISS flight decision.
What NASA facility received the installation is not specified in the contract description. Candidates include NASA Kennedy Space Center (plant biology at KSC) or NASA Johnson Space Center (life support integration).

Portfolio Domains¶
Space Lab Technologies has active or completed work in at least four distinct technology domains:
| Domain | Key Programs |
|---|---|
| Food production | LILYPOND (duckweed hydroponics), MarsOasis (crop automation), G-LILYPOND / UG-LILYPOND |
| Life support hardware | PLSS water processing ($755K), PHILM CO₂ membrane ($156.5K), HEART habitat analytics |
| Habitat sensing | SOSH — Sensor Optimization for Space Habitat Awareness ($156.4K, 2024–2025) — NEW |
| Thermal control | Freeze-tolerant radiator Phase I ($156.5K, 2024–2025) |
| ISRU / lunar mining | EcoMine Phase II IGNITE ($899.8K, 2024), EcoMine KREEP Phase I ($156.5K, 2024), EcoMine Phase I IGNITE ($150K, 2024) |
This breadth is unusual for a small SBIR company. Most small companies in this portfolio specialize tightly (Busek = electric propulsion, Protoinnovations = rover mobility). Space Lab Technologies is following multiple threads simultaneously. The SOSH Phase I (Session 76 discovery) adds a fifth domain — habitat environmental sensing — further confirming the pattern of opportunistic SBIR diversification across the full ECLSS/habitation technology space.
The EcoMine Pivot¶
EcoMine is Space Lab's most dramatic pivot. The concept: use biological processes (microbes, plant-derived chemistry?) to extract rare earth elements and minerals from lunar regolith — specifically KREEP terrain (potassium, rare earth elements, phosphorus — geologically enriched areas of the Moon). This is fundamentally different from growing food crops.
The Phase II IGNITE award ($899.8K, 2024–2026) is a substantial commitment from NASA to this concept. IGNITE is a specific NASA SBIR Phase II track for technologies with high commercial and mission potential. The parallel KREEP Phase I ($156.5K, 2024–2025) suggests a second EcoMine track exploring a different regolith target.
Bioregenerative ISRU (using biology to process in-situ resources rather than purely mechanical/chemical processes) is a frontier concept. If EcoMine works, it would represent a genuinely novel approach to lunar resource extraction.

Session 76 Update: New SOSH Award, EcoMine Triple-Track, Escobar PhD¶
New findings¶
- SOSH Phase I ($156.4K, 2024-2025): "Sensor Optimization for Space Habitat Awareness" — a fifth technology domain for this company. Habitat environmental sensing adds to food/ECLSS/thermal/ISRU. Total portfolio now $4.1M+.
- EcoMine has THREE awards (not two as originally tracked): Phase I IGNITE ($150K, 80NSSC24PA312), KREEP Phase I ($156.5K, 80NSSC24PB445), and Phase II IGNITE ($899.8K, 80NSSC24CA217). NASA is investing ~$1.2M total in EcoMine — substantial for a concept this early.
- Escobar pursuing PhD at CU Boulder on CELSS robust design — her academic research feeds directly into the company's products. This explains the breadth: each SBIR proposal maps to a dissertation-adjacent research question.
- Duckweed confirmed as the target crop — family Lemnaceae, aquatic plant requiring no soil. This is a more specific and defensible niche than "thin-film hydroponics" implies.
- Colorado School of Mines collaboration (Dr. Jaeheon Lee) on EcoMine — adds geological/mineral processing expertise to Space Lab's biology-first approach.
Assessment update¶
The PhD connection is the key insight: Space Lab's unusual breadth isn't random SBIR chasing — it's a PI building a systematic dissertation around CELSS design that spans food, atmosphere, water, sensing, and ISRU. Each award maps to a subsystem of the same architectural question. This is the academic-entrepreneur pattern at its most deliberate.
Open Threads¶
- Which NASA facility received the LILYPOND Lab Test Suite? Kennedy? Johnson? This matters for understanding the ISS path.
- EcoMine Phase II: what biological mechanism does it use — microbial leaching? Plant-derived acids? Understanding the mechanism would clarify feasibility.
- Has Christine Escobar published on thin-film hydroponics results from the FO parabolic flights? (Web search found no publications yet)
- The freeze-tolerant radiator Phase I (2024) is architecturally distant from food production — is this a completely independent engineer/team within Space Lab, or Escobar pivoting again?
- MarsOasis ($754.9K, 2019–2024): was this a fully distinct crop system or a scaled variant of LILYPOND for Mars pressure/atmosphere?
- NEW: What is SOSH specifically sensing? Air quality? Radiation? Microbial contamination?
- NEW: FO project 106694 end date is Dec 2025 — has NASA closed it? Any final report?
