快科技8月24日消息，据新华社报道，记者日前从中国载人航天工程办公室了解到，本着稳妥可靠、万无一失的原则，经综合研判，嫦娥七号任务不满足发射条件，不能在今年预定窗口实施。 (ECNS) -- A roughly 600-square-meter swimming pool in Haoling Village, Yingtan City, east China's Jiangxi Province, has become a favorite summer destination for children from nearby villages. The pool, with a depth of 1 to 1.6 meters, is open free of charge from 4 p.m. to 8 p.m. every day during the summer. A safety attendant is on duty, while village officials take turns to patrol the area for children's safety. A Haoling Village official said the free pool was built to prevent children from swimming in open water, reducing the risk of drowning, adding that it is a small but practical thing the village Party branch has done for local residents. According to Xinhua news, the pool was built two years ago. Pool water is drawn from Baita canal and later discharged into farmland for irrigation, allowing the water to be reused. The pool is open for more than two months each summer. Since videos of the pool went viral, children from surrounding villages have flocked to the pool, with some parents even bringing their children from the city about 20 kilometers away.

B | 任务目标是突破高精度月面软着陆、腿式行走、月面飞跃及月面永久阴影坑探测等关键技术，通过绕、落、巡、飞跃等综合探测方式，对月球南极开展环境与资源勘查。其着陆区选址月球南纬85度以上的南极区域，核心科学目标之一是探测月壤水冰和挥发组分，并为国际月球科研站建设奠定基础。而不能在今年预定窗口发射，这一消息来得相当突然，因为就在8月19日，嫦娥七号探测器和长征五号遥十四运载火箭刚刚在文昌航天发射场完成垂直转运，器箭组合体已转运至发射区，原计划近日择机实施发射。更早之前，探测器已于今年4月通过空陆联运运抵文昌，火箭则于7月13日海运送达，此后数月一直按计划开展总装和测试工作。至于推迟发射的具体原因，还需等官方后续的详细通报。官宣！嫦娥七号任务不满足发射条件不能在今年预定窗口实施
