Will Mars, a candidate for human migration, create a water map?

The survey found no water or ice at a depth of 300 meters from the landing site of the Mars InSight rover. As a possibility, the scientists highlighted the need to create a map showing the distribution of water on Mars.

A research team from the University of San Diego in the US has suggested that there is no groundwater on the plains of Mars Elysium since NASA’s Mars Insight rover landed on the official channel on the 20th day.

InSight, which landed on the Elysium Plain near Mars’ equator on November 27, 2018, was designed to reveal the interior of Mars. InSight used the Internal Structure Seismic Experiment (SEIS) in April 2019 to observe the Hwajin Marsquake for the first time.

SEIS, which experienced a total of 1,300 volcanic earthquakes last June, has revealed through seismic analysis the fact that Mars’ core is liquid and its size, as well as the thickness of the crust.

The research team, analyzing seismic data from SEIS, found that the crust of Mars is porous and fragile, and the deposits are not connected to each other. In addition, in the case of the InSight landing site, it was calculated that the infill between the sediment particles at a depth of 300 m was mainly gas, and there was no ice, or even if it was 20% or less.

A spokesman for the research team said: “Water that existed on the ancient surface of Mars in the form of lakes or seas appears to have disappeared due to the decomposition of water vapor carried to the upper atmosphere by ultraviolet radiation, or its entry to Mars. I think it might be,” he said.

Indeed, in May 2008, NASA’s Phoenix Mars probe detected what looked like ice under the surface of the Borealis Basin, near the north pole of Mars. The European Space Agency’s Trace Gas Orbiter (TGO) Mars Exploration Orbiter has detected the possibility of large amounts of water in the form of ice or minerals on the relatively shallow surface of the central Marineris canyon, near the equator of Mars.

In 2008, the Phoenix spacecraft dug up 7-8 cm of the surface of Mars using a robotic arm. The scientists assumed that the white matter was ice.

If the research team’s claim is correct, it is unlikely that there was any form of water, at least around the InSight landing site. The research team’s position is that if observational equipment such as SEIS extracts more extensive data from the Martian surface, they can map the distribution of water on Mars as they do on Earth.

Mapping the waters of Mars has long been a subject of debate in the academic community. NASA, the Japan Aerospace Exploration Agency (JAXA), the Canadian Space Agency (CSA), and the Italian Space Agency (ASI) are currently working on an international Mars exploration plan called “Mars Ice Mapper” that identifies liquid or ice. water. Buried underground on Mars. Ice Mapper, MIM) “In consideration.

Mars, along with the Moon, is a celestial body that is considered a candidate for human migration to the planet. Although the surface of Mars, which has a thinner atmosphere and has lost much of its magnetic field compared to Earth, is a hostile environment, it is shielded from radiation and could potentially support life in the presence of water, the researchers said. researchers. . If there is water or ice below the surface that can be easily extracted, there is a good chance that this will be useful for future manned missions to Mars.

NASA and the European Space Agency are currently working together on the Mars Sample Return (MSR) program. The Persevering rover, which landed last February, has been collecting rock samples from the surface. On July 30, both parties announced through their official channels that the review of the system requirements for the MSR has been completed and the Phase 3 mission to transport valuable samples collected by the probe from Mars to Earth has been confirmed.

NASA indicated at the time that it would use two small helicopters for the mission. In addition, the company announced that it will focus on the development of the Mars Life Explorer (MLE) mission, which over the next 10 years will collect samples from a depth of 2 meters in the high latitudes of Mars.

Whatsapp beta testers now have to analyze another novelty that could be a revolution for users. This is a beta version of messenger 2.22.22.7 which brings news about sending documents. The information was published on WaBetaInfo and reproduced on the technology portal Olhar Digital.

At the moment the new tool is only available to some beta users (including previous versions), but Meta has already been working on it in version 2.22.21.2. This feature will allow, as with photos and videosthe user submits documents describing himself.

Currently, when sending a document, there appear to be files, which can cause confusion for both the sender and the recipient. For those who receive it, the situation is even worse, since, in order to later find the file, it is difficult to find it. With the insertion of descriptions for sending these documents, it will be easy to find through the app’s search tool.

Also, according to WaBetaInfo, Meta plans to test the new feature for more users in the coming weeks. Further updates to the app are already in the testing process. WhatsApp is one of the most popular instant messengers in the world, coverage of about 2 billion active users.

Imagem de: Google pretende dobrar vendas de celulares Pixel em 2023

BUT Google set ambitious targets for the company’s smartphone division for 2023. Nikkei Asiagiant’s goal is to sell twice as many Pixel phones next year compared to the expected figures for 2022.

To achieve this goal, the manufacturer has already ordered more than 8 million units of models. Pixel 7 e Pixel 7 Pro, submitted this Thursday (6) along with other proprietary devices, like a tablet this is smart watch.

Furthermore, over 4 million units on one “The cheapest pixel” would also have been ordered for an early 2023 launch. So far, there is no word from the company about launching another smartphone in the coming months.

The previous generation of mobile phone brands, Pixel 6 It was the fastest selling Google smartphone in history. The last cheapest model was Pixel 6awhich has been sold since the second half of this year.

However, it is worth remembering that the company sells these and other models only in selected markets, which does not include Brazil. With ambitious plans, perhaps in the future the company will begin to bring devices to other markets.

The original report contains the same information from two different sources on the subject, but Google hasn’t commented on the case.

GAME BOOSTERS improve mobile performance? We have tested!

GAME BOOSTERS improve mobile performance?  We have tested!

Do you know that little window that stays open on your mobile when you go to play? Today we will study it in detail. Game Boosters, do these gaming performance apps work or is it all bullshit and placebo effect? This is what we are going to discover today at Roda Liso.

GAME BOOSTERS work or not?

Some time ago I was tagged in a group Smooth wheel in Telegram I suggest testing gaming accelerators from smartphone brands if this feature really delivers better performance while gaming. So I went there with all the fun, I set aside some time a day to test the game with and without the booster activated and was amazed: NOTHING CHANGED! That’s all for today, until the next video…

But calm down, let’s figure out what does not work out? Check it out, Game Booster is a smartphone app that allows you to clear memory and optimize gaming performance. What it does is eliminate programs running in the background and give priority to the running game. Having said that, I end here and point out that the difference between turning the game booster on and off when your mobile is already well prepared to run the game is minimal, something like 3, 4 frames.

real test

But I decided to go further: and if you test a smartphone in two extreme and absurd situations? My first game was with the included game booster, everything was fine, the games started as they should. The second game was made to fully extrapolate the BASIC RULES OF THE WORLD: Facebook, Instagram, YouTube, Camera and a bunch of other things running in the background.

tested smartphones

We use smartphones from three different brands and three games on each of them. Brands Samsungas Galaxy S22, Motorolaas Edge 30 e xiaomias SMALL F4. We have selected 3 of the hardest games we know: Genshin Impact, Life After and Tower Of Fantasy.

Samsung Galaxy S22

Genshin Impact

With graphics set to maximum quality, we got the result 58 FPS average with 91% stability without using Game Booster.

With Game Booster activated, we had a much better result, 60 frames at 99% stability. The question here is not what Booster does, but how its performance is affected by the simultaneous execution of several applications.

fantasy tower

We also played Tower Of Fantasy at max with 90 FPS turned on. Here we had a big difference in results, since without Game Booster we achieved an average of 39 frames with 77% stability.

Now that all inclusive is nice, take 60 average frames, 79% stability. You can see on your own a clear difference between the two gameplays, without a booster everything is much worse.

Life after

In Life After, the overall result hasn’t changed much, but you can see very obvious performance differences just by filming the gameplay itself. Without Game Booster and with maximum graphics, we averaged 42 frames with 69% stability.

With the booster activated, we scored 45 frames, 74% stability. Okay, the difference in numbers is not that big, but the experience during the game, the feeling of performance, it’s very noticeable, since Game Booster has eliminated a lot of those crashes and stutters that we had.

SMALL F4

Genshin Impact

POCOs usually have a slightly more advanced Game Booster system than other brands as it shows FPS, CPU usage and allows us to create performance optimization profiles for each game. In Genshin, when everything is at its maximum, With Game Booster off and a few apps running in the background, we got an average frame rate of 48 with 91% stability.

It didn’t change much after enabling Booster, but we did get a stability boost with less FPS fluctuations: 48 medium frames, 98% stability.

fantasy tower

In Tower Of Fantasy we got the opposite result. The game started playing at 53 FPS at 84% stability with Game Booster disabled.

Shortly after performance 52 frames at 71% with him. The booster didn’t affect Tower of Fantasy, it probably happens to other games as well, as it’s not possible to match the application with all existing games.

Life after

In Life After, the difference was minimal, with a POCO score 36 fps on average, 99% stability initially, no booster enabled.

With the application running, we reached the average value 39 FPS, 98% stability. You can see that the change happened in a different way, not for stability, but for rawer FPS, which is also always welcome.

Motorola Edge 30

Genshin Impact

The Edge 30 uses a different boost method than I’m used to seeing, you’ll notice the results we got. In our Genshinzer we took 46 average frames, 97% stability with Game Booster off and complete nonsense running in the background.

Now, by activating “high performance mode”, the result changes dramatically, it’s even funny how it works. We took an average of 57 frames with 97% stability.what a miracle,

fantasy tower

In Tower Of Fantasy, I can already say that we didn’t have much difference, no. With everything off and apps running in the background, we averaged 57 FPS with 87% stability.

When high performance mode is enabled we achieved a frame rate of 59 with 100% stability. What I noticed the most here is the consistency of the frames, they changed less, but otherwise the result was the same.

Life after

The last test video is here, let’s go. Without the booster, we got a low frame rate of 31 frames with 99% stability.quite a nasty performance to play, let’s face it.

After turning on Game Booster, we achieved a very satisfactory result. 49 average FPS with 93% stability. This was one of the games where I noticed the biggest difference in high performance mode, obviously the extra smoothness the optimizer gave us.

What did you understand?

Many people are biased towards mobile phone optimizers because most of the time it seems like they don’t do anything. Both Nicholas and I hated these Lifetime Game Boosters because we thought they did nothing but turn off notifications and close background apps.

Turns out we’ve been wrong all along (partly because there are still some game boosters out there that actually just clear the RAM and mute the phone). In this series of tests, we proved two points: playing with many applications in the background affects its performance and that optimizers really help.

The important detail is that A LITTLE this is Motorola warn us that smartphone can get very hot using “gaming way”, which happened. Keep in mind that enabling these performance options will cause your finger to burn from the hot screen, and that’s the price you pay for a few extra frames.

Now we have an additional question for you: who was the most impressed with the results? O Edge 30 by Motorola, to be sure. I was horrified by the jump in smoothness that the Edge 30 made when I turned on the “high performance” option, the difference in frames is instantaneous. But one cannot ignore A LITTLE, with its customization menu giving us the option to create specific profiles for every game we play. Another point to note about POCO is that its performance has stayed the same with apps running in the background and Game Enhancer enabled, which means this device handles background operations better and already has very high performance in pattern mode.
