A pound of prevention

A weary general and three young engineers stand on the brink of a daring Mars launch, aware that any failure could shut down the nation’s space program for a century. The crew’s mission is as much about proving a new neutron‑reflecting reactor can power the voyage as it is about surviving the cramped, sterilized capsule that will carry them into the void. Their briefings are laced with dry humor and a palpable sense of responsibility, knowing the world’s hopes rest on their shoulders.

Beyond the technical jargon, the story finds its heart in the everyday concerns of men far from home. Aréchaga, a tropical‑born cook, frets over the bland, irradiated rations and longs for a taste of fried beans, while Hagstrom and van den Burg joke about pickled fire bombs and the absurdity of eating in zero‑gravity. Their banter masks the underlying anxiety of quarantine, possible Martian contamination, and the unknown that awaits beyond the launch window.

As the clock ticks toward the early‑morning medical check, the trio undergoes a ritual of preparation—showering, shaving, and the dreaded blood draws—each step a reminder that even the smallest oversight could become “an ounce of prevention” too costly in the unforgiving expanse of space.
