 What can you infer about the environment within the Delta Crucis in terms of its suitability for growing marocca?
Captain Hannah climbed painfully down from the Delta Crucis , hobbled across the spaceport to where Beulah and I were waiting to greet him and hit me in the eye. The fruit of the marocca is delicious and fabulously expensive. Transshipped seeds invariably failed to germinate, which explained its rarity. The Myporians were usually, and understandably, bitterly, opposed to letting any of the living plants get shipped off their planet. But when I offered them a sizable piece of cash plus a perpetual share of the profits for letting us take a load of marocca plants to Gloryanna III, they relented and, for the first time in history, gave their assent. You know that marocca takes a very special kind of environment. Bright sun most of the time—that means an almost cloudless environment. Days and nights the same length and no seasons—that means no ecliptical and no axial tilt. But our tests showed that the plants had enough tolerance to cause no trouble in the trip in Delta Crucis ." "You'll remember that I warned you that we should take some marocca out into space and solve any problems we might find before committing ourselves to hauling a full load of it?" asked Captain Hannah. If we had gone through all of that rigamarole, we would have lost the franchise. I almost asked him why he had been barricaded in the bathroom of the Delta Crucis , but I figured it was safer to let him tell me in his own way, in his own time. The plastic film kept the water in the hydroponic tanks without any trouble, even in a no-gravity condition. So I lined up the Delta Crucis perpendicular to her direction of motion, put a once-every-twenty-one hour spin on her to match the rotation rates of Mypore II and Gloryanna III, and uncovered the view ports to let in the light. It gradually brightened until 'noon time', with the ports pointing straight at the light source, and then dimmed until we had ten and one-half hours of darkness. With no gravity for reference, how were the plants supposed to know that the 'sun' was supposed to be moving?" I just put enough spin on the ship to make artificial gravity, and then I strung a light and moved it every fifteen minutes for ten and one-half hours, until I had gone halfway around the room. "Of course, first I had to move all the hydroponic tanks from their original positions perpendicular to the axial thrust line of the ship to a radial position.
 The Delta Crucis is capable of sustaining marocca plant life with appropriate interventions.
 The Delta Crucis can not sustain marocca plant life.  The Delta Crucis is capable of sustaining marocca plant life with appropriate interventions.  The Delta Crucis must be operated by multiple individuals at a time to sustain the marocca in transport.  The Delta Crucis can sustain marocca plant life if small batches of the plants are transferred at a time.
