Decades have passed since the United States abandoned the moon landing in the last century, and now it has been announced that it will do so again this century. There is some curiosity as to the reasons for this. One wonders why the US is restarting its moon landing program. It has never been a principle that the United States lives by, never doing anything that is not profitable, so most people think that the United States must have found something profitable on the moon. What could it be?
According to information recently obtained by scientists, over 6 trillion kilograms of solid ice has been found on the moon. In other words, there is water on the moon. Who would have thought that the moon, which appears to be nothing, could contain such a huge amount of water? Could this be the root cause of the US moon landing? We cannot be sure.
The Moon has long been conquered by man, and human footprints have long been left on the Moon. People have a full understanding of the Moon.
The Moon is a satellite of the Earth, it orbits the Earth and follows it around the Sun. Due to the tilt of the Moon itself, there is a clear bifurcation on the Moon, meaning that half of the Moon always has its back to the Earth and the Sun.
The Moon itself tends to be positioned in a straight line with a rotational inclination of only 1.5 degrees, which makes it difficult for the north and south poles to receive direct sunlight. Combined with the impact of meteorites on the north and south poles, many areas have sunken, making it even harder for the Moon to be illuminated by the Sun.
So half of the Moon is always 'dark'.
In areas where the sun never shines, temperatures reach -170 degrees Celsius and even -250 degrees Celsius in some areas. Such low temperatures cause some of the substances in this region to be trapped forever. Examples include moisture and carbon dioxide.
In fact, scientists have long believed that there is water on the Moon, and they started looking for water sources in 1952. From the very beginning, scientists believed that water sources existed in the north and south planes of the Moon. After all, there are many craters there, places where the sun does not shine, and where water is most likely to be found.
However, many people don't think so, because humans have never found water.
In 2009, to find out if there was water on the Moon, the tip of a Centaur rocket was used to impact the surface of the Moon's craters, and then the dust from the impact was collected by relevant equipment. After testing, this dust was found to contain 155kg of water, suggesting the presence of water in the dark parts of the Moon.
So how did the water get to the moon? Scientists speculate that the water molecules on the moon were left behind after a comet hit the moon and then preserved as solid water. In addition, some scientists say that a large number of volcanic eruptions brought out the thin atmosphere, which then underwent a series of evolutions and eventually formed water.
Now that the moon has been proven to have water, it is understandable that the US has restarted its plans to go to the moon. The US plans the Artemis mission with the aim of acquiring lunar materials and exploring the possibility of establishing a base. The best place to do this would be on the dark side of the moon where there is water.

AI WEATHER PREDICTION
on September eleventh 2023 climate predictions in the northeast of the US sounded like this all eyes are on Hurricane Le the storm has bolstered lower back to a class three we're awaiting it to make a northward flip over the subsequent few days through September sixteenth after being downgraded storm Lee made landfall in Nova Scotia Canada flooding roads Downing timber and slicing out strength for tens of heaps of humans alongside the east coast at least five days earlier than storm Lee struck land climate forecast had roughly anticipated its trajectory however some other forecast beat them three days earlier than climate stations an AI mannequin created by way of Google expected the Cyclone's route the AI revolution has reached meteorology and it is at a time when we are responding to excessive climate greater than ever we're about to discover out if it will help us put together with the aid of bringing the future into Clear View predicting future climate greater than a few hours out begins with growing a picture of Earth's present day surroundings scientists do that with the aid of amassing records from sources Like Satellites and climate stations and buoys placed round the world taking images of clouds and measuring temperature and strain and wind pace and humidity all that disperate facts receives fed into computer systems which generate a 3D grid of packing containers that symbolize the surroundings each vertically and horizontally computer systems then do a lot of physics to decide how these prerequisites have interaction with every different and they produce a forecast I suppose any forecast has like a hundred and fifty trillion calculations it is exceptionally notable all that math requires some of the world's most effective supercomputers the two large ones are run by using the European Center for medium-range climate forecasts and the National Weather Service in the US to make a neighborhood climate forecast from this Global mannequin meteorologists zoom in and ref locate their very own forecast with their nearby information like if they stay in a hilly location or a flat vicinity or close to a lake they shall alter these fashions and do their personal expert interpretation based totally on their region no count what this preliminary 3D grid of environment is by no means going to precisely replicate fact there is too many gaps in the information we can measure that skill forecasts get blurrier the similarly out you go which is why the large climate facilities do not simply generate one forecast they tweak the preliminary records and produce up to 50 forecasts it is known as Ensemble forecasting and it helps meteorologists measure uncertainty if all 50 forecasts appear comparable there may be a greater sure bet in the prediction however if there is a lot of variant there may be a whole lot much less we acquired to type of preserve an eye to the sky there may be a conceivable up below the storm in the works this one from 0% threat to 40% at 2:00 70% at 8:00 and at 11:00 we had a tropical storm climate facilities solely launch their forecast each 6 hours due to the fact that is all brand new computing electricity will enable however what if that limmit did not exist earlier than we provide an explanation for that we are going to hear.

The Ocean Crisis Caused by Microplastics
The proliferation of microplastics in the world's oceans represents a dire environmental crisis. These minuscule plastic fragments, often less than 5 millimeters in diameter, infiltrate marine ecosystems and pose severe threats to aquatic life, human health, and the overall integrity of marine environments. This article explores the origins, impacts, and potential solutions to the ocean crisis caused by microplastics.

The problem with being a nice person
Who would have thought that being a nice person could be problematic. The majority of people would tell you that’s what they want to be or at least want those around them to be, but as it turns out, what we want and what we say we want are worlds apart. I won't stress or ramble on about how I would like things to be, but I’ll just analyze why this is, I am not sure either if a solution is even possible.
