Orbital Runtime Coming Q2 2026 — The Orbital Runtime is currently in development.
This documentation is a design preview. Request early access
to be notified when it’s available.Overview The Orbital Runtime provides execution primitives designed for the unique constraints of space:
Why a New Runtime? Standard cloud runtimes assume:
Assumption Reality in Space Always-on network Intermittent connectivity Stable power Variable solar/eclipse cycles Predictable latency Orbital geometry dependent Reliable hardware Radiation-induced faults
The Orbital Runtime is built from first principles for these constraints.
