美国滞留宇航员提前返回地球 定于星期二晚着陆

滞留在国际空间站九个多月的美国宇航员,预计提前于星期二(3月18日)晚上返回地球。

法新社报道,美国国家航空航天局(NASA)星期天(16日)发布声明说,国际空间站滞留在宇航员威尔莫尔和威廉姆斯,定于格林尼治标准时间星期二晚上9时57分(新加坡时间18日早上5时57分),在美国佛罗里达海岸附近的海域着陆。

两人返回地球的最早着陆时间原先设定在星期三。NASA说:“新的返回目标使空间站成员有时间完成交接工作,同时便于灵活应对预计本周晚些时候出现的不利天气条件。”

美国太空探索技术公司(SpaceX)的载人“龙”飞船(Crew Dragon),赴国际空间站执行第10次为国际空间站运送轮换宇航员的任务。飞船星期天与国际空间站成功对接,待宇航员完成交接工作后,接回滞留在空间站九个多月的威尔莫尔和威廉姆斯。

NASA宇航员海格(Nick Hague)和俄罗斯宇航员戈尔布诺夫(Aleksandr Gorbunov),也将随“龙”飞船一同返回地球。

Telegram auto-delete message, expiring invites, and more

elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.

How Does Telegram Make Money?

Telegram is a free app and runs on donations. According to a blog on the telegram: We believe in fast and secure messaging that is also 100% free. Pavel Durov, who shares our vision, supplied Telegram with a generous donation, so we have quite enough money for the time being. If Telegram runs out, we will introduce non-essential paid options to support the infrastructure and finance developer salaries. But making profits will never be an end-goal for Telegram.
