At 8:19 on July 19, my country used the Long March 2C carrier rocket at the Xichang Satellite Launch Center to successfully launch 10 sets of remote sensing 30 satellites into the air. The satellites successfully entered the scheduled orbit, and the launch mission was a complete success.

The mission also carried and launched 15 stars in the constellation of Apocalypse.

This is the 380th flight of the Long March series of carrier rockets.

According to the Sensor Tower report, TikTok has been downloaded 3 billion times (including TikTok for iOS), making it the first non-Facebook app to achieve this achievement.

Specifically, TikTok is the fifth application with 3 billion downloads. The top four are all owned by Facebook, namely Facebook, Messenger, WhatsApp and Instagram.

Sensor Tower also recently released the ranking of global mobile app downloads in June. Douyin and its overseas version TikTok have won the global mobile app (non-game) download list with more than 65 million downloads.

Recently, HMS Core 6.0, the core service of Huawei mobile phones, was officially launched, and users can upgrade. This service is not only compatible with Huawei mobile phones, but also supports installation on third-party Android devices, providing basic services such as Huawei account login, payment, positioning, and security.

The update log shows that HMS Core version 6.0 has enhanced security features for Huawei accounts and optimized service experience.

Huawei HMS Core 6.0 released: further enhance security and optimize service experience

HMS Core also provides developers with a message push function and the ability to quickly log in to a Huawei account. Developers can call this service to implement in-app positioning, payment, maps, games, and machine learning services. Non-Huawei mobile phones need to install this service if they want to use Pollen Club, Huawei Music, etc.

Huawei HMS Core 6.0 released: further enhance security and optimize service experience

According to previous news, Huawei announced the upcoming global release of HMS Core 6.0 at the 2021 Huawei HMS Global Application Innovation Competition held on June 10. Officials said that the number of applications that integrate HMS Core globally reached 134,000. At present, HMS has become the third largest mobile application ecosystem in the world.

According to the China Aerospace Science and Technology Group Sixth Academy, on July 6, the test run of the new liquid oxygen kerosene engine test bench developed by the Sixth Academy was a complete success in the Sixth Academy's 165 Academy. This test bed can be used to test 120-ton engines. After it is put into production, it will greatly improve the development and test capabilities of my country's 120-ton liquid oxygen kerosene high-pressure afterburning engines.

It can be seen from the figure that this test bed is built in the valley, which is beneficial to shielding noise and reducing the impact on the outside world. During the test run, a large amount of water vapor was ejected from the special outlet, and the fire inside the test bench was faintly visible.

The 120-ton engine series will be used in the take-off stage of a new generation of liquid carrier rockets. Officials said that with the further implementation of my country's manned spaceflight, lunar exploration and other large space projects, as well as the development of commercial spaceflight, the demand for a new generation of liquid carrier rockets and their engines is increasing. The success of this test run provides a strong guarantee for the engineering application of the engine and further meets the needs of my country's next-generation launch vehicle follow-up missions.

News on June 17 According to the China Manned Space Engineering Office, the Shenzhou 12 manned spacecraft successfully completed its orbital status setting after it entered orbit. At 15:54 on June 17, 2021, Beijing time, it will adopt autonomous rapid rendezvous and docking. The model was successfully docked at the forward port of the Tianhe core cabin, forming a three-cabin (ship) combination with the previously docked Tianzhou-2 cargo spacecraft. The entire rendezvous and docking process lasted about 6.5 hours.

This is the first rendezvous and docking with a manned spacecraft after the Tianhe core module was launched into orbit. According to the mission implementation plan, three astronauts will then enter the Tianhe core module from the Shenzhou 12 manned spacecraft.
