NASA’s Jet Propulsion Laboratory announced that the Perseverance rover’s science team was able to track the formation of four “dust devils” and three large dust clouds in the first 216 days of the rover’s operation on the Red Planet.

“During the first months of work, we collected a huge amount of data on the behavior of dust on Mars. Ironically, our wind sensors were badly damaged for the reason that we were able to track the phenomena that we wanted to study in detail.said NASA Jet Propulsion Laboratory worker Manuel de la Torre Juarez.

The measurements made for the first time allowed scientists to estimate the frequency of appearance of “dust devils” and dust clouds in the Jezero crater, where the Perseverance rover landed in July 2020. Corresponding measurements should have been carried out on board the Curiosity rover, but its meteorological sensors were partially damaged during landing in Gale Crater.

Their counterpart, the MEDA instrument aboard Perseverance, escaped a similar fate, allowing NASA and their colleagues in Spain to track how dust particles exchange between the Martian atmosphere and surface. In addition, scientists were able to establish in detail how many accumulations of dust rose above the Jezero crater at different times of the day.

The measurements made by the researchers showed that dust whirlwinds often appeared in this part of Mars. On average, each day, the Perseverance instruments recorded the passage of about four “dust devils” through different regions of the Jezero crater, and in four cases these swirls originated directly next to the rover.

At the same time, scientists found that rarer clouds of dust, which periodically rose into the atmosphere as a result of powerful gusts of wind, contained significantly more particles of matter than “dust devils”. This, according to de la Torre Juarez and his colleagues, is evidence that these clouds are the main source of dust in the Martian atmosphere.

Samsung has released a smartphone that neither Xiaomi nor Huawei

Samsung has introduced a secure smartphone Galaxy XCover6 Pro. The manufacturer has not yet revealed the price, but earlier there were rumors about 600 euros. The device will go on sale in July.

Samsung has released a smartphone that neither Xiaomi, nor Huawei, nor Realme offers the likes of.  Introduced secure Galaxy XCover6 Pro with a removable battery

Unlike many of its predecessors, the Galaxy XCover6 Pro offers far from the most basic specs. The heart here is the Snapdragon 778G, which means that the XCover6 Pro is more productive than most Samsung smartphones in the Galaxy A line.

The device has 6 GB of RAM, 128 GB of flash memory that can be expanded with microSD cards, a 50-megapixel main camera, an 8-megapixel ultra-wide resolution, a 13-megapixel front camera, and a 6.6-inch IPS screen with a resolution of Full HD + with support for 120 Hz. The display is covered with the latest Glass Victus + glass, but probably a film is glued on top, as is usually the case with secure smartphones.

The battery capacity is small by today’s standards and amounts to 4050 mAh, but the device’s battery is removable, that is, you can replace it yourself by simply opening the back cover. Moreover, hot swapping is supported.

Also worth noting is a USB-C 3.2 port, Wi-Fi 6E, Bluetooth 5.2, two customizable buttons, and DeX support. As for protection, we are talking about IP68 and the MIL-STD-810H standard.

The new helmet is being created for the PlayStation 5 console, although many hope to be compatible with the PC. The novelty is expected to receive OLED displays with a resolution of 2000 x 2040 per eye, support for HDR, a frequency of 120 Hz and a viewing angle of 110 degrees. The novelty is also credited with eye tracking and a single data and power cable, while the new controllers will receive adaptive triggers and an advanced vibration mechanism.

The new helmet is said to support Horizon Call of the Mountain, No Man’s Sky, The Walking Dead: Saints & Sinners: Retrebution and Resident Evil Village. Other games are also expected to appear.

There is no exact release date yet, it is assumed that the helmet will appear in the first half of 2023. He is credited with a cost of 400 euros.

FCC asks Google and Apple to remove TikTok app from

In the US, a new stage of confrontation between the authorities and TikTok has begun. FCC Commissioner Brendan Carr wrote letters to Alphabet CEO Sundar Pichai and Apple CEO Tim Cook. In them, he demanded that TikTok be removed from the Google Play and App Store stores.

According to Carr, the application collects and transfers too much sensitive data, and then the program transfers them to Beijing. Carr noted that the application can save drafts, has access to search history, intercepts button presses, tracks biometrics, and also has access to text, images and videos on the clipboard.

“TikTok is not just an app for sharing funny videos and memes. This is a wolf in sheep’s clothing, ”the American official said. He also stated that a recent study showed that TikTok employees in China had access to the personal data of American users.

Stores were given until July 8 to remove the app or justify their refusal to do so. Note that this is not the first confrontation between the Chinese application and the US authorities. Previously, ByteDance companies wanted to ban transactions on TikTok.
