NASA滞留宇航员成功返回地球
在经历了286天计划外太空任务后，NASA宇航员布奇·威尔莫尔和苏尼·威廉姆斯于本周二结束创纪录的9个月太空滞留，搭乘SpaceX龙飞船安全降落在墨西哥湾。NASA连续推迟返回时间表，最终选择切换到SpaceX作为救援方案。考虑到本周晚些时候的不稳定天气，NASA提前让他们启程。
两位宇航员的太空飞行历程创造多项记录：累计行程1.95亿公里（1.21亿英里），完成4,576次地球轨道运行，威廉姆斯更以62小时太空行走刷新女宇航员累计时长记录。在延长期内，他们转型为正式空间站成员，承担设备维修、科学实验等任务，威廉姆斯还担任过空间站指挥官。

Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”
