The Spark Plan

As early as the 1990s, the United States had attempted to build a miniature artificial ecological cycling system in the desert north of Tucson City, Arizona. It was intended to support ecological and environmental research in a sealed environment, help humanity understand how Earth worked, and investigate conditions that simulated Earth's ecology.

The project was originally proposed by a football player and received investment from several financial groups, including Rockefeller. With a price tag of US$150 million, it caused quite a stir at the time.

Unfortunately, the eventual results were nowhere near as sensational as the idea had been when it was first proposed. After holding out for just one year, the experimental team living in Biosphere 2 declared the project a failure and had to withdraw.

The only conclusion the experiment produced was that Earth might be the only home suitable for human life.

Overall, the project was undoubtedly a failure. Not only did Biosphere 2 fail to establish an ecosystem capable of sustaining itself independently, but it even narrowly escaped being converted into an eco-hotel after the project ended.

Given the historical context, however, the idea was remarkably pioneering, and some of the technologies it produced went on to shine in many other fields.

Judging by the tasks assigned by the system, there was more than a ninety percent chance that the third stage of the mission chain involved establishing a permanent or semipermanent settlement, or a scientific research station, on the Moon. Although the first stage, a crewed lunar landing, had yet to be completed, that did not stop Lu Zhou from preparing for the future.

Besides, even the first stage included side missions such as "farming on the Moon" waiting for him.

Thus, after several detailed discussions with experts from the Hua Academy of Sciences, the
