The system also features a ventilation mechanism that draws in air from the environment at a constant rate. The air is given a set level of humidity and temperature to ensure consistent measurements. The idea, says Stevan, is to install several of these “noses” throughout the garden to create a sensor network.
He notes a number of advantages of this system over current approaches to determining ripeness, including that it works online, conducts continuous real-time analysis in an open environment, and does not require direct contact with the fruit, which is usually done in a laboratory or in warehouses, after harvest or during storage.Oh, this Mars! How many interesting things have been said about it. We have watched many films about Martians, we have heard stories about how they are going to conquer it, it has even been praised in songs. Humanity is very actively studying this planet and is considering the possibility of its settlement in the near future. We just need to figure out how to terraform the surface and change the atmosphere. All the study so far leads only to the collection of data and various discoveries, including explanations of the processes taking place. In the course of these studies, scientists receive beautiful photographs with unusual phenomena, most of which they can already explain. Believe me, there is something to look at in these photographs!
Is Mars similar to Earth?
We are used to the fact that Mars has already become somehow familiar to us. It even seems to us that it is similar to Earth. In some ways it is, but there are also many differences. For example, it is much smaller and more rocky. Its atmosphere is 96 percent carbon dioxide, which appears as a result of seismic activity. The pressure at the surface of Mars is about 170 times lower than at the surface of Earth, or the same as on Earth, but at an altitude of about 35 kilometers.
What makes it even further away from us is what we have long benin number data been accustomed to on our planet. For example, a sunset or a solar eclipse. At this moment, it becomes most clear that Mars is very different from Earth.
Is there water on Mars?
There is no definitive answer about liquid water, scientists sometimes find it somewhere below the surface, then say “oh no… we were wrong.” But there is definitely ice on the surface, although its exact composition is not fully known.
It is located in the Korolev crater, near the northern polar ice cap of Mars. The crater is 81.4 kilometers wide and is filled with water ice year-round.
As local air moves over the crater, it cools and sinks, leaving a layer of cold air directly above the ice inside the crater. Gases are generally not good conductors of heat, and this cold layer perfectly insulates the ice mass from warmer currents passing above. This way, the ice is reliably protected from melting by the crater rim.
The ice sheet is 1.8 kilometers thick and up to 60 kilometers in diameter, with a volume of about 2,200 cubic kilometers. That's not much compared to, say, Antarctica, but it's much more than you'd expect from a planet as arid as Mars.
While the study shows that the e-nose system already has a high accuracy of over 98 percent, the researchers are continuing to work on its components, focusing on improving the instrument's flow analysis. They have filed a patent application and are exploring its commercialization prospects.
