SpaceX公司14日第三次尝试发射“星舰”，取得较大进展。
“星舰”于美东时间9时25分从得克萨斯州博卡奇卡基地发射升空。所有33台“猛禽”发动机均正常点火。随后“超重型推进器”和顶部的“星舰”飞船顺利“热分离”。
“星舰”飞船似乎完美登上太空。不仅“星舰”飞船的速度接近将其送入亚轨道所需的速度，而且还完成了打开和关闭有效载荷舱门，转移推进剂等测试。
“星舰”飞船约40分钟后进行再入大气层。但不久之后，团队就与飞船失联。“星舰”在再入过程中失去了与“星链”和跟踪与数据中继卫星的通信，这暗示飞船已经解体。SpaceX团队表示，由于失联将不再有溅落。

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.
I have no inside knowledge of a potential stock listing of the popular anti-Whatsapp messaging app, Telegram. But I know this much, judging by most people I talk to, especially crypto investors, if Telegram ever went public, people would gobble it up. I know I would. I’m waiting for it. So is Sergei Sergienko, who claims he owns $800,000 of Telegram’s pre-initial coin offering (ICO) tokens. “If Telegram does a SPAC IPO, there would be demand for this issue. It would probably outstrip the interest we saw during the ICO. Why? Because as of right now Telegram looks like a liberal application that can accept anyone - right after WhatsApp and others have turn on the censorship,” he says.
