A | 2024年中国航天大会4月24日在湖北武汉开幕。在大会主论坛上，线上发布了2024年宇航领域十大科学问题和技术难题。 中国科学院院士、中国航天科技集团有限公司研究发展部部长王巍受中国宇航学会和中国航天大会学术委员会委托，进行了发布。
B | SYDNEY, Australia -- Soccer officials in Australia and Indonesia have floated the idea of teaming up in a bid to rival Saudi Arabia for the hosting rights to the men’s World Cup in 2034.The Sydney Morning Herald reported comments Wednesday from Indonesia soccer federation president Erick Thohir about ongoing talks that could also include Malaysia and Singapore in a possible bid.Indonesia is being linked with a bid despite having the men’s Under-20 World Cup taken away by FIFA this year amid political turmoil because the Muslim-majority nation did not want to stage games involving Israel.Argentina ended up hosting the under-20 tournament at short notice.FIFA could have disciplined the Indonesian federation for breaching hosting duties but instead rewarded the country weeks later by naming it as host of the men’s Under-17 World Cup. Israel did not qualify for the under-17 edition, which starts next month.Thohir is an Indonesian government minister who has ties to FIFA president Gianni Infantino. Both are members of the International Olympic Committee and Thohir is a former president of Inter Milan, the Italian soccer club whose fans include Infantino.Any opponent to Saudi Arabia in the 2034 World Cup contest has to express official interest by Oct. 31. FIFA set a deadline of Nov. 30 to file a formal bidding agreement.Only members of the Asia and Oceania soccer bodies can apply to host the 2034 World Cup because the United States, Canada and Mexico will host the 2026 edition and six FIFA members from Europe, Africa and South America have joined for the 2030 tournament.Within hours of FIFA opening the 2034 contest a week ago, the Saudi Arabian soccer federation pledged to bid and Asian Football Confederation president Sheikh Salman bin Ebrahim Al Khalifa said there was united support for it. Four AFC members now appear to be in talks to contradict that statement.The Australian soccer federation, which successfully co-hosted the Women’s World Cup this year, said last week it is “exploring the possibility of bidding for the 2029 FIFA Club World Cup and/or the FIFA World Cup 2034.”The 32-team club event in 2029 is expected to be played in June-July, a time of year unsuited to the extreme summer heat in Saudi Arabia.FIFA has said it will decide which months to play the 2034 World Cup after its members confirm the host at a meeting likely to be held late next year.___AP soccer: https://apnews.com/hub/soccer。这十大科学问题和技术难题分别是：地外资源利用的重力场效应问题，地外天体介观尺度动力学问题，空间带电粒子操控机理与方法，面向载人深空探测的火星二氧化碳原位利用技术，冰巨星探测任务设计与关键技术，月基平方公里射电天文天线阵列建造技术，太空计算中心构建及运行技术，小天体探测与开发的智能柔性附着技术，航天遥感大模型的产业化应用技术，重复使用火箭复用快速评估验证技术。 据介绍，这是继2020年中国航天大会首次发布宇航领域科学问题和难题以来的第五次发布活动。5年来，相关问题研究助推了科研项目的立项与实施，对于布局航天前沿科技发展方向，打造原创技术策源地都具有重要意义。（记者侯文坤、田中全）。
