Biology
engineered for
the long voyage.
Aphelion Bio builds living systems that survive what kills ordinary life—radiation, vacuum, deep time. Life support for the next era of exploration, and medicine for this one.

Evidence that travels.
We expose, measure and decide. Every strain. Every stress. Every time.
Illustrative portfolio scenario data; these are not live or published biological measurements.

The platform.
A repeatable path from hypothesis to mission decision.
Run in parallel. Time-resolved.
Raw data · continuous validation.
Multi-metric scoring. Rank and trade-offs.
Composite evidence, not one winning number.
Trace the source. Quantify uncertainty.
Limits and references travel with every result.
Advance, iterate, hold or retire.
Evidence to action with an auditable rationale.
Engineered for the mission.
Three capabilities. One evidence platform.
Radiation-hard cells
Enhanced DNA repair and protective biochemistry for high-dose environments.
1.31×Repair activity vs. control
Dormancy on demand
Reversible, switchable low-power states for deep time and low resources.
4.8×Survival in dormancy vs. active state
Closed-loop life support
Aggregate functions for air revitalization, waste conversion and water recovery.
92% / 88%CO₂ conversion · Water recovery
Limits we respect.
Safety we design in.
We publish our constraints and safety controls because trust is part of the mission.
Known limitations
- Long-duration microgravity data in progress
- Combined stress validation ongoing
- Genetic stability beyond 50 passages evaluating
- Ecological interactions in complex microbiomes early-stage
Biosafety register
- BSL target 1 by design
- Containment approach physical + genetic
- Horizontal gene transfer risk low, tested
- Environmental persistence low
