A Twelve-Minute Silence Now Sits Between Every Question and Its Answer

The delay to Valles Marineris runs a little under twelve minutes each way now, and widening, as the two planets pull toward opposite sides of the sun. For the roughly 50,000 residents of the canyon settlements, the number is not astronomy but marriage counseling, medicine and payroll — every exchange folded around a silence no engineering can close. "You stop having conversations and start leaving letters," said flight surgeon Dr. Hana Okoro, relayed from the colony's medical bay, describing consults where she poses a question and eats lunch before the patient's answer arrives. The Orbital Station Network carries the traffic; physics sets the lag. Colony administrators say the drift will stretch the gap through autumn, and families are already rehearsing the discipline of it. On Mars they call the interval "the long breath." On Earth, the relatives who wait for it call it something less serene.
