She heard someone call her name softly, a man’s voice. She saw that she was in a college dorm sleeping in the bottom bunk of a bunk bed. But the room was otherwise empty. A streak of light moved across the wall, like streetlights inside a moving car. She looked outside the window and saw that, behind the familiar Chinese parasol tree, the Sun swept across the sky rapidly, rising and setting every few seconds. Even when the Sun was up, however, the sky behind it remained inky black, and the stars shone along with the Sun. The voice continued to call her name. She wanted to get up to look around, but found her body floating up from the bed. Books, cups, her notebook computer, and other objects floated around her….
Cheng Xin woke up with a start, and found herself truly floating in air, hovering a small distance above the sofa. She reached out to pull herself back onto the sofa, but inadvertently pushed herself away. She rose until she was next to the porthole in the ceiling, where she turned around weightlessly and pushed against the glass, successfully sending herself back to the sofa. Everything looked the same in the cabin, except that the weightlessness released some of the settled dust motes, and they sparkled in the sunlight.
She saw that an official from the PDC had come up from the cabin below. It was probably he who had been calling her name earlier. He stared at her, astonished. “Dr. Cheng, I understand this is the first time you’ve been in space?” he asked. After Cheng Xin nodded, he smiled and shook his head. “But you look like an old spacer.”
Cheng Xin herself felt surprised as well. This first experience of weightlessness did not cause her discomfort or anxiety. She felt relaxed, and there was no dizziness or nausea. It was as if she naturally belonged here, belonged to space.
“We’re almost there,” the official said, pointing up.
Cheng Xin looked up. She saw the guide rail again, but now she could tell they were moving by its surface—a sign that they were slowing down. At the end of the rail, the geosynchronous terminal station was coming into view. It was formed of multiple concentric rings connected together by five radial spokes. The original terminal station was just a small part in the center. The concentric rings were later additions, with the outer rings being newer. The entire structure slowly rotated in place.
Cheng Xin also saw other space buildings appear around her. The dense cluster of buildings in this region was the result of engineers taking advantage of proximity to the space elevator terminal station for transportation of construction materials. The buildings were of different shapes and appeared from the distance as a bunch of intricate toys—only when one swept past at close range could their immensity be felt. Cheng Xin knew that one of these housed the headquarters of the Halo Group, her space construction company. AA was working in it right now, but she couldn’t tell which building it was.
The elevator car passed through a massive frame. The dense struts in the frame made the sunlight flicker. By the time the car emerged from the other end of the frame, the terminal station took up most of the view, and the Milky Way twinkled only from the space between the concentric rings. The immense structure pressed down, and as the car entered the station, everything dimmed as though the car was entering a tunnel. A few minutes later, bright lights illuminated the outside: The car was in the terminal hall. The hall spun around the car, and for the first time Cheng Xin felt dizzy. But as the car detached from the guide rail, it was clamped by the platform. After a slight jolt, the car began to spin along with the station, and everything around her seemed to be still again.
Cheng Xin, accompanied by four others, emerged into the circular hall from the car. As their car was the only one at the platform, the hall seemed very empty. Cheng Xin felt a sense of familiarity right away: Although information windows floated everywhere, the main structure of the hall was built from metallic materials that were rare in this age, mainly stainless steel and lead alloys. She could see the marks left by the passage of years everywhere, and she felt herself situated in an old train station instead of in space. The elevator she had ridden was the first space elevator ever built, and this terminal station, completed in Year 15 of the Crisis Era, had been in continuous operation for more than two centuries, even through the Great Ravine. Cheng Xin noticed the guardrails crisscrossing the hall, installed to help people move around in weightlessness. The guardrails were mainly made of stainless steel, though some were made from copper. Observing their surfaces, bearing the marks of countless hands through more than two centuries of service, Cheng Xin was reminded of the deep ruts left in front of ancient city doors.
