The Engineering Gap

Crew Health Has Hit
a Physiological Ceiling.
Gastronaut Raises It.

Today's astronauts perform extraordinary work on rations engineered for a different era. The data below shows where the gap is. The next section shows how we close it.

"Diet and exercise, proper nutrition and resistive exercise in space. It's a breakthrough that doesn't get enough credit." John Grunsfeld, Former NASA Chief Scientist, 41st Space Symposium, April 2026
"We were eating from tubes. Today's crews deserve a salad bar at L1." Brian Lichorowic, Founder & CEO, Gastronaut LLC

The Mars math, rewritten.

Without intervention, crews lose body mass through every phase of a long-duration mission. The decline plateaus, then erodes again as physiological reserves run down.

Gastronaut closes the gap with fresh, peer-reviewed phytonutrient profiles delivered daily. The green band shows the projected trajectory with ORCA onboard.

The Platform

The platform that closes
crew health at the source.

Gastronaut is not a garden. It is a combined life-support subsystem delivering nutrition, atmospheric processing, gut-brain protection, and vision support in a single crew-rack footprint.

One Rack. Four Systems.

The ORCA rack integrates CRISPR microgreen production, atmospheric processing, behavioral nutrition delivery, and vision-protective phytochemistry into a single crew-rack footprint. Continuous output. Closed-loop water. Edge automation.

Four Functions. All Compounding.

Every Gastronaut rack delivers four overlapping mission-critical functions. They compound, which is why the unit economics close where competitors stall at single-function payloads.

01

Cellular Defense (Nrf2)

+1.86 SD

CRISPR edits produce 2.3 to 3.1 times more protective enzymes. The body's master switch for cellular self-repair, activated by sulforaphane from broccoli microgreens.

02

Atmospheric Processing

20 to 25%

120 to 240 mmol of CO2 scrubbed per day. Roughly one quarter of an astronaut's daily atmospheric load. Gastronaut moves from consumable to ECLSS subsystem.

03

Brain Protection (Gut Health)

d = 0.84

Prebiotic-rich microgreens maintain gut microbiome integrity via the gut-brain axis. LunAres analog: +1.78 SD behavioral improvement across 30 studies, n = 2,071.

04

Vision Protection (SANS)

75% addressable

75% of long-duration astronauts develop optic disc edema. B-vitamin delivery plus Nrf2-mediated retinal protection. Validated by JAMA Ophthalmology, 2024.

Full Offset. Zero Decline.

Combined analysis of 28 independent studies. The model explains 71% of variation in crew wellbeing. Every contributing factor is statistically significant at p < 0.01.

Five Pillars. All Compounding.

At the 41st Space Symposium, no panelist mentioned a single competitor. Three national space agencies are calling. The Canadian Space Agency sent a formal letter: "Protect this idea."

01
Patents Allowed

Centrifuge plus automation IP protected. CRISPR crop variety patents in filing.

02
1,042 Growth Cycles

Proprietary data from NASA G-Space. Years to replicate. Cannot be purchased.

03
Peer-Reviewed

npj Microgravity 2025. No competitor has achieved published results.

04
First-Mover Window

Station integration 2026 to 2028. After stations are built, retrofitting is cost-prohibitive.

05
Nrf2 Pathway Science

No competitor operates at the pathway level. Generic antioxidants already failed. This is the scientific moat.

Key Insight

"The device sells 1-2 units. The biology scales infinitely."

This reframing transforms a ~$200M hardware exit into a $600M to $900M biotech platform. CRISPR licensing drives the margin story. Once the crop biology is validated, every new license costs near-zero in incremental R&D.
