SpaceX团队完成人类首次载人围绕地球两极飞行任务，4名宇航员搭乘龙飞船成功降落太平洋。此次任务于上月底从佛罗里达发射升空，历时约4天，宇航员在430公里高空轨道观察探索地球两极。
期间团队开展22项科学实验，包括首次在太空拍摄人体X光图像和尝试种植蘑菇，并通过可穿戴设备监测宇航员健康数据，研究微重力环境对人体影响。

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
A leaked Telegram discussion by 50 so-called crypto influencers has exposed the extraordinary steps they take in order to profit on the back off unsuspecting defi investors. According to a leaked screenshot of the chat, an elaborate plan to defraud defi investors using the worthless “$Few” tokens had been hatched. $Few tokens would be airdropped to some of the influencers who in turn promoted these to unsuspecting followers on Twitter.
