}Orbital Docking Concierge Briefing
Welcome to Meridian Transfer Ring. Docking in four minutes. Please secure loose items, confirm your berth number on the panel to your left, and keep the central passage clear for incoming crew. If this is your first time rotating through partial gravity, take a slow breath and let your balance adjust before standing. Connecting departures to Europa freight, inner-orbit commuter lines, and the museum shuttle will begin boarding twenty minutes after arrival. And for passengers meeting family at Gate C, yes, they can see you wave through the glass.

}Desert Relay Station Dispatch
Central de relevo Sierra Nueve, atención. Si escuchan este mensaje, mantengan la calma. Hemos recuperado energía parcial en el anillo exterior y el sistema de enfriamiento vuelve a responder, pero el corredor norte sigue bloqueado por polvo y escombros. Prioridad uno: personal médico al módulo dos. Prioridad dos: equipo técnico con filtros nuevos a la compuerta este. No corran, no saturen el canal y confirmen su ubicación al llegar. Repito: la situación está contenida, pero necesitamos movimientos precisos y ordenados. En diez minutos emitiré una nueva actualización.
