What did we expect? Norton asked himself. A committee of welcome? He was not sure whether to be disappointed or relieved. The initiative, at any rate, appeared up to him.

His orders were to wait for twenty-four hours, then to go out and explore. Nobody slept much that first day; even the crew members not on duty spent their time monitoring the ineffectually probing instruments, or simply looking out of the observation ports at the starkly geometrical landscape. Is this world alive? they asked themselves, over and over again. Is it dead? Or is it merely sleeping? On the first EVA, Norton took only one companion—Lieutenant Commander Karl Mercer, his tough and resourceful life-support officer. He had no intention of getting out of sight of the ship, and if there was any trouble, it was unlikely that a larger party would be safe. As a precaution, however, he had two more crew members, already suited up, standing by in the airlock.

The few grams of weight that Rama’s combined gravitational and centrifugal fields gave them were neither help nor hindrance; they had to rely entirely on their jets. As soon as possible, Norton told himself, he would string a cat’s-cradle of guide ropes between the ship and the pillboxes, so that they could move around without wasting propellants. The nearest pillbox was only ten metres from the airlock, and Norton’s first concern was to check that the contact had caused no damage to the ship. Endeavour’s hull was resting against the curving wall with a thrust of several tons, but the pressure was evenly distributed. Reassured, he began to drift around the circular structure, trying to determine its purpose.
