slow, taking months to spiral in.
    The few dozen passengers and their life support system made up barely two percent of the huge vehicle’s pay-load. The rest of the cargo was industrial materials that couldn’t be made on Earth. Light and ultrastrong foamsteel girders from New New. Whisker matrices from Von Braun. Impossibly pure beryllium from Devon’s World, tonnes of it, and exotic alloys from B’ism’illah Ma’sha’llah and Mazeltov. Each weekly flight involved an exchange of money equivalent to the gross national product of a small country.
    The people riding on top were baggage, an afterthought The accommodations and food reflected this.
    O’Hara spent a lot of her time exercising. Three stationary bicycle contraptions that could be worked with hands or feet stood opposite the only window in the craft Faced with the prospect of walking around for a year in Earth-normal gravity, she exercised her legs most. Also, being strapped on the bicycle was the only opportunity she had to sit down, that posture being unnatural in zerogee. She worked up quite a sweat and got it back in the form of one liter of water per day. for washing.
    She slept well, strapped up standing against the wall, and read a lot of books and magazines, and watched more cube than she ever had in her life, and became an expert in the art of the zerogee toilet. She kept to herself. There would be a year of being nice to strangers, groundhogs at that. Mudballers. Earthies. Must forget those words for the time being; must not bristle at being called a spacer. As if there were no difference between a Devonite and a Yorker.
    For days there seemed to be no change in the appearance of the Earth: the same face she had seen all her life, as New New marched in lockstep over northern Brazil. Then Africa and Europe peeked over the edge, and the Americas began to slide away. Sere Asia over the vast Indian Ocean. One day there was almost nothing but water, the Pacific framed by little bits of Australia and Alaska. The globe began to grow, and eventually its rotation was perceptible from hour to hour.
    A fat nuclear tug was waiting for them at the edge of the Van Allen belts, through which the ion-drive slowboat could not pass. They switched payloads. The outward-bound cargo was mostly hydrogen, food, acids, and a few economy-class passengers, including a dance troupe cursing their tightwad manager.
    O’Hara and the others felt acceleration for the first time, a gentle nudge. They cruised into low Earth orbit—the globe now spinning dizzily below them, once each ninety minutes—and the passengers transferred to a small shuttle-craft (the cargo went into large cone-shaped crafts called “dumbos,” which would be robot-guided into splashdowns near the purchasers of each load).
    Even though she had taken the required tranquilizer, O’Hara felt growing excitement, along with a little apprehension.In space, almost all transportation is graceful and slow, not to say boring. She knew the shuttle would be fast and violent, though safe: only two had crashed in her life-time.
    She strapped herself in and waited. There was no countdown, just a steady growing surge of acceleration. From her window she could see the dumbos shrink away, then sweep out of her field of view as the shuttle tilted to present maximum area to the atmosphere, for braking. She was weightless again, no feeling of motion. Her window showed nothing but stars.
    For long minutes nothing happened. Then the curve of the Earth rolled up, stopped, rolled back out of sight, making her a little dizzy. She had seen this on the cube a dozen times and wasn’t scared at all. A high-pitched moan sat at the edge of audibility when the steering jets stopped blasting: the atmosphere slowing them down.
    O’Hara might have compared the middle part of the trip to a
