NASA's Gateway could become the Moon's first airport – here's how traffic will work

China's postponement of its Chang'e-7 lunar mission, aimed at searching for water ice near the moon's south pole, may slow its lunar ambitions but is unlikely to alter the broader competition with the United States over establishing a lasting presence on the moon, according to space experts. The mission, which was postponed due to an approaching tropical storm, will now launch next year.

A major space security strategist explained that US professionals would not be happy about the delay, as similar issues have affected US lunar missions in the past. However, politically, the delay might ease some pressure on NASA, as it pushes back the prospect of another successful Chinese moon landing, reducing media and political concerns in Washington.

A space research researcher noted that Chang'e-7 was an especially ambitious mission, with its combination of an orbiter, lander, rover, and a hopper designed to investigate permanently shadowed regions. While all lunar missions are complex, this particular one had narrow launch windows due to its reliance on solar power. The spacecraft needs to touch down near the start of a near-continuous sunlight period to maximize its exploration time.

The southern lunar pole is a challenging region for landing due to its steep slopes, craters, and deep pits, making safe landing sites difficult to identify. The delay might give the US a chance to reach the south pole region first. This delay does not mean China is losing the competition, as it is part of a larger, sequential lunar program with the next mission, Chang'e-8, focusing on resource utilization.

The competition is more about translating individual missions into a sustained presence in lunar and cislunar space and building an international coalition around a shared vision for lunar exploration and governance.
