Settling Into Orbit
Halo Arc never stopped moving. It circled Earth every ninety minutes. The residents learned to live with constant sunrise and sunset through the observation windows. They worked, slept, and grew food in a rotating schedule.
Hydroponic bays stretched across the inner rings. Rows of green vegetables lined transparent channels. AI monitored pH levels, moisture, and growth rates. The replicators handled protein blocks, yeast-based nutrients, and an experimental fish culture.
Marcus inspected a malfunctioning pump with two engineers.
“We have twenty hours before the lettuce batch fails,” he said.
Engineer Sato frowned. “We can reroute the water feed. The tubing needs welding.”
“Print it,” Marcus said. “Send the specs to Fabricator Three.”
3D printers have evolved beyond anything from the early century. They used recycled materials, vacuum formed alloys, and programmable carbon. The team could replace almost anything except the station’s largest structural sections.
Social Life
The residents rotated through education modules. Children learned physics, agriculture, and languages. Adults worked six-hour shifts. Every person had duties. Trust kept the station alive.
During a community meeting, a teacher, Lila Nakamura, raised a concern.
“The children are asking about the world below. They see the frozen clouds and want answers.”
Alina nodded. “Tell them the truth. Earth is cold but not gone. We watch and wait. When temperatures return, we return.”
A young father stood. “Do we know when that will be?”
“No,” Alina said. “But we prepare every day.”
Problems Appear
The first major issue came with the oxygen garden. A fungal infection spread through the moss beds. The AI flagged it within minutes. Engineers isolated the bay and began sterilizing.
Marcus briefed the command team.
“If we lose two more beds, we drop below safe oxygen levels.”
Colonel Rajan asked, “Do we have a backup?”
“We can grow new cultures, but it takes time.”
“Do it,” she said. “No delays.”
The crew worked through the night. Replicators printed sterilized trays. Biologists introduced new moss samples. By morning, the infection was gone.
