"Our current plan is—"
A researcher in work clothes stood beside Hao Yi and Li Cheng. Looking at the busy crowd around them, he explained slowly,
"Use a rocket to launch the lander into an orbit with a perigee of 600 kilometers, an apogee of 110,000 kilometers, and an orbital period of 48 hours."
"110,000 kilometers?"
He Ao turned to look at the researcher beside him. "That's where the Transparent Planet is?"
"Yes."
The researcher nodded.
"According to the plan, when it reaches apogee, the lander's two sections—the descent module and the Orbital Returner—will separate.
"Then, the descent module will attempt to descend onto the Transparent Planet's surface. The explorer can leave the descent module to conduct exploration, while the Orbital Returner continues orbiting.
"If everything goes smoothly, once the operation is over, the explorer can return to the descent module. After discarding some nonessential equipment, the descent module will ascend back into orbit, dock with the Orbital Returner, and then return to the ground."
He paused and glanced at the documents in his hand. "However, the Transparent Planet is a celestial body unlike anything we have encountered before. It has no gravity, and we do not know whether it has an atmosphere. We also do not know whether it possesses a physical form.
"So we prepared more fuel for the descent module, allowing it to return to orbit even if the landing fails. But as a result, the explorer will have less room to move around."
"Mm, that shouldn't be a problem."
He Ao nodded lightly. He looked up at the enormous rocket launch tower in the distance, where final inspections were underway beneath the night sky. "How much longer until it's ready?"
"About three hours."
The researcher nodded.
"How long will we
