The Shenzhou|13 crew have safely returned to Earth after their epic six|month orbital trip, which nearly doubled the previous record of China's longest single|flight space mission of 92 days set by the Shenzhou|12, some eight hours after the manned spacecraft's detachment from the Tianhe core module. 我感觉缺少介词。请教！
some eight hours after the manned spacecraft's detachment from the Tianhe core module.
你理解错误。这并非名词作状语，而是after引导的时间状语从句，只是after被名词词组修饰而已。
