The Perseverance rover has tracked the formation of “dust devils” on the Red Planet. One of them damaged the rover’s sensors.
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.

The iPhone 16 and Galaxy S24 lines will not receive an increase in RAM compared to their predecessors, despite the hype around AI
Samsung smartphones from the Galaxy S24 line and devices from the iPhone 16 line will likely retain the same RAM options that current models currently have.
Analysts at Mizuho Securities, cited by insider Revegnus, say that the growing demand for AI should, in theory, contribute to the growth of RAM in smartphones. We previously reported that thanks to the emphasis on AI, manufacturers may begin to actively equip their smartphones with 16-24 GB of RAM.
However, a significant increase in memory prices, as well as the still missing scenarios for local AI that will run directly on smartphones, will lead to the fact that next year manufacturers will not actively increase the amount of memory. In particular, Samsung and Apple can leave everything as it is now.
This means that the iPhone 16 and 16 Plus will each receive 6 GB of RAM, and the iPhone 16 Pro and 16 Pro Max will each receive 8 GB. Samsung’s new generation flagships will have 8 or 12 GB of RAM.
It is likely that other manufacturers will not rush to increase volumes, and this, in turn, may slow down the development of local AI on smartphones.

“Button island”, Exynos 1280, AMOLED screen 120 Hz, 50 MP with OIS, 5000 mAh. Samsung Galaxy A25 presented
Samsung today introduced not only the Galaxy A15, but also the Galaxy A25. This model is built on the proprietary SoC Exynos 1280, and its design feature is the so-called “button island”. This is the elevation of the side frame in the area of the power and volume keys.
Galaxy A25 received an AMOLED screen with a diagonal of 6.5 inches, Full HD+ resolution, frame rate of 120 Hz and maximum brightness of 1000 cd/sq.m. Interestingly, unlike the younger model, there are versions with both 8 GB and 6 GB of RAM (the Galaxy A15 has strictly 8 GB), the flash memory capacity is only 128 GB.
The main camera of the Galaxy A25 has three sensors with a resolution of 50, 8 and 2 megapixels. The main module has optical stabilization. Front camera with 13 megapixel sensor.
The battery capacity is 5000 mAh, and supports 25 W wired charging. One UI 6.0 out of the box is used as the shell. Dimensions and weight of the smartphone are 161 x 76.5 x 8.3 mm and 197 grams. Price: $270.
Today Samsung officially unveiled the budget smartphone Galaxy A15. The new product is offered in two versions: with LTE and 5G. Accordingly, the first is built on the MediaTek Helio G99 SoC, and the second is based on the MediaTek Dimensity 6100+ SoC. In terms of everything else, these versions have no differences.
The Galaxy A15 4G has two memory configurations: with 8 GB of RAM and 128 or 256 GB of flash memory. The Galaxy A15 5G has one memory configuration: 8/1256 GB.
Samsung Galaxy A15 received a Super AMOLED screen with a diagonal of 6.5 inches, a resolution of 2340 x 1080 pixels, a frame rate of 90 Hz and a peak brightness of 800 cd/sq.m. The battery capacity is 5000 mAh and supports 25 W charging.
The camera is represented by sensors with a resolution of 50, 5 and 2 megapixels. The front camera is 13 megapixel. Dimensions and weight of the smartphone are 160.1 x 76.8 x 8.4 mm and 200 grams.
Galaxy A15 launched in Vietnam. The price of the LTE version is from $200, the 5G version is $260.
