Statement
Deep Space Network service and star tracking are operational in defined mission contexts; optical communication and pulsar-navigation capabilities have separate demonstrations and limitations; delay-tolerant networking has standards and bounded deployments.
Evidence dimensions
- Basis
- demonstrated
- Readiness
- major scale up
- Confidence
- strong
Assessment rationale
Official records establish operational DSN service and separate demonstrations of optical communication, autonomous optical and pulsar navigation, and delay-tolerant networking. Their distances, accuracy, power, infrastructure, duration, and autonomy boundaries remain unlike an interstellar multigenerational mission.

Assumptions and limits
The assessment applies to this bounded statement and the cited source scopes. A source can support one relationship without validating a generation ship, and an editorial grade does not substitute for independent review or representative demonstration.
What would change this conclusion?
Longer independent missions with measured clock, catalog, pointing, link, archive, software-recovery, sensor-diversity, maintenance, and outage performance would narrow the scale-up gap; a single new distance or rate record would not.
