Chinese college students send self-developed satellite into orbit_我的网站

一 |     (ECNS) -- A student satellite team from Harbin Institute of Technology successfully launched its self-developed Lilac-3 satellite into orbit, marking a milestone for a young team involved in independent satellite development.    The satellite was launched aboard a Gravity-1 Y4 carrier rocket from waters near Shanghai at 10:54 a.m. on July 22. Telemetry data was successfully received at 11:41 a.m., confirming the mission’s success.    Lilac-3 features an ultra-flat disk-shaped design, with its main body measuring less than 5 centimeters in thickness. The design allows satellites to be stacked more efficiently during launches and is expected to support future low-orbit constellation deployment.    When the project began, about 70% of team members were undergraduates, with an average age of 22. Most had no previous experience with complete satellite engineering projects and learned new technologies during the development process.    After the first Lilac-3 failed to enter orbit due to a launch failure earlier this year, the team rebuilt the satellite within three months, improving its performance and adding new experimental tasks.    Founded in 2012, this team is the first university student team in China to independently complete satellite design, development and mission management. Lilac-3 is the fourth satellite successfully launched by the team.    (By Intern Liu Shuangjing, Zhang Dongfang)                    。昨天，微信发布了“2018年微信数据报告”。截至2018年9月，微信每月活跃用户超过10亿，其中有6300万人年龄在55岁以上。00以后，人们喜欢“遮住脸”，“90以后”喜欢“笑和哭”，“80以后”喜欢“笑”，“70以后”喜欢“遮住嘴”等等。对于这个微信的数据报告，我们可以看到一些小额信贷账户。然而，微信数据报告的内容也引起了用户对隐私保护的讨论。一些用户甚至质疑微信统计是否涉嫌监控用户的聊天内容。

二 | 对于用户的查询，腾讯回应称，微信年度数据报告中的所有数据都是匿名的、不敏感的，不涉及特定用户的隐私内容。

三 | 据《新京报》报道，针对网民对微信监控用户聊天的质疑，腾讯回应称：“微信不会读取或保留任何用户的聊天记录，聊天内容只会存储在用户的手机、电脑等终端设备上。”腾讯表示，微信年度数据上报的所有数据报告匿名且不敏感，不涉及特定用户的隐私内容。此外，据报道，腾讯副总裁丁科于2017年8月15日明确表示，微信的价值取向绝不会让用户互相聊天，并明确表示微信不会阅读和分析聊天记录。另一方面，该报告指出，与腾讯关系密切的人士表示，“腾讯在用户聊天中使用了SSL加密技术。这项技术是通用的。任何使用该技术的公司都可以从技术上查看信息，但不会这样做。”对于SSL（安全套接字层）技术，南洋理工大学互联网相关专业博士后朱聪（化名）解释说，用户之间发送和接收的信息将通过这项技术。当信息在用户和服务器之间传输时，信息被加密。当信息在服务器上时，它以未加密的形式存在。

四 | 服务器可以查看、修改甚至检查消息的内容。朱聪说，从技术角度看，微信确实具有查看聊天信息的能力。
