MG-J26
The genetic baseline mission. Nine months in low Earth orbit. Three measurement layers waiting at the other end.
A baseline for what space does to cannabis genetics.
Horizon is the genetic baseline mission. The payload flies with Genesis II SFL for nine months in low Earth orbit. Cannabis sativa L. seeds will live through microgravity that has no analog on Earth, and through cosmic radiation that the atmosphere otherwise filters out for the rest of us.
When the capsule returns, we measure what changed at three levels of biological organization. This is the dataset the program is built on. Every flight after Horizon compares against it.
Three layers, in order.
Mutation frequency
How often the DNA itself changes. Single-nucleotide variants, indels, structural rearrangements — counted against the pre-flight reference genome.
Epigenetic shift
Which genes were methylated or demethylated in flight, and whether those marks persist after return. The flight signature on the regulatory layer.
Heritability
Which changes are passed to F1 offspring grown back on Earth, and which are flight-only. This is what makes a space-bred line a line.
These three layers answer a different question than "did the seeds survive." They answer what changed and what is inheritable. The first is interesting. The second is the program.
Minimal facts. Final manifest in launch week.
We are not publishing seed counts or line counts before the payload is final. The manifest goes up the week of launch, with seed IDs and parent provenance attached.
Seeds, telemetry, and a six-layer measurement stack.
Twelve months of ground analysis follows recovery. The dataset publishes in stages: telemetry first, phenotype and chemistry next, sequencing layers last. Every release is on the record.
