We’ve said it before, and we’ll say it again - space is hard. Another example, albeit lacking in the destructive displays of some past examples, is China’s recent delay of its Chang’e-7 lunar mission. The agency announced the mission would miss its late-August launch window with a very brief press release from the China National Space Administration and the China Manned Space Engineering Office. While that means a slight delay in China’s plan for the Moon, it’s only a matter of time before the cornerstone of the robotic lunar exploration program is back on the launch pad.
