00:00Friends, humans are intelligent beings who have been worried about their future from the beginning.
00:06We are living in our present.
00:08But despite this, we are always worried about our future.
00:13This is why we often look for life on other planets in space.
00:19Because if for some reason there is any destruction on our earth and the earth is destroyed,
00:25then we can go to that planet and save our life and start life again there like the earth.
00:32And friends, we know that to live life and to start our life,
00:37the most important thing we need is water.
00:42And this is why scientists keep looking for water on all the planets of the solar system.
00:48But let us tell you that this search is now over.
00:51Scientists have found huge oceans of water on one of the planets of our solar system.
00:56And this planet is none other than Mars, the closest planet to our earth.
01:02But friends, it is not so easy for us humans to go to Mars.
01:05Because the distance from our earth to Mars is so far that if you want to take a kilo of goods here,
01:12then you will have to spend at least 150 million rupees for it.
01:16Which tells us that it can be very expensive for us to take the things we need and go to Mars.
01:22Because as the weight increases, the transportation cost of the mission will also increase.
01:28And doing this is a loss of business point of view.
01:32Friends, Elon Musk has been working on this project for a long time.
01:36And his attempt is to reduce the transportation cost on Mars.
01:41But nothing like this has happened yet.
01:43How long will this be possible?
01:44And whether it will happen or not, it cannot be said.
01:47And in this case, friends, if you go on a Mars mission, then you have to take water with you.
01:55And according to the weight, we will have to spend a lot of money to take water to Mars.
02:01Because we need more water than food.
02:04If we want to go to Mars and produce some food, then we will definitely need water.
02:10This is why scientists look for water before finding any element on Mars and the moon.
02:16And scientists have often been successful in the case of Mars.
02:21Similarly, in 2008, Phoenix Lander, who was observing Mars,
02:26recorded data from there for about 161 days and sent it to our Earth.
02:31In this data, we got to see a trench.
02:33This trench is known as Dodo Goldilocks.
02:37Friends, if you look carefully, you will see some white in this trench.
02:42And this white thing is nothing but ice.
02:45Similarly, a report was published in November 2017.
02:50And in this report, it was told about the presence of hydrated salt on Mars.
02:56In addition, in 2005, the Omega instrument of the Mars mission also discovered hydrated elements on Mars.
03:04Friends, many times we have got many such proofs,
03:07from which it is known that there is permafrost in the south pole of Mars.
03:13Permafrost is the water that is present in the soil in the mixed form on the surface of Mars.
03:19In addition, in 2012, the Curiosity rover present on Mars also discovered a dry landmark on Mars,
03:27which looked exactly like a stream belt.
03:31Friends, the stream belt is also called the physical formation,
03:34which is formed due to the flowing water.
03:37And after meeting this stream belt, it was clear that at one time there were many water reserves on Mars.
03:45Friends, scientists had already known that there are many water reserves on Mars,
03:50but these reserves were of no use to scientists.
03:53And the reason for this was sublimation.
03:55Friends, the trench we just told you about,
03:58that part of the trench was previously covered with an ice cap.
04:01But the environment of Mars is such that only within 4 days,
04:05this ice cap turned into gas due to the environment,
04:09that too within just 4 days.
04:12And this fast sublimation on Mars points to this thing
04:17that no matter how many ice caps are on Mars,
04:20they will soon turn into gas due to being in contact with the atmosphere.
04:24And by the time we humans go to Mars and build colonies,
04:27maybe there will be no ice cap left here,
04:31through which any civilization can live here.
04:34But now such a discovery has been made,
04:36which has ended this problem forever.
04:39Scientists have found an underground water reserve on Mars.
04:43And these water reserves have been found due to the Inside Lander,
04:47which has recorded a lot of data from March 2018 to 2022.
04:54Friends, there was also a seismograph in this Inside Lander.
04:58Seismograph is a machine that detects earthquakes etc.
05:02And this seismograph recorded about 1300 seismic activities
05:06on the surface of Mars within 4 years.
05:10And some of them were recorded here due to the fall of the metroid.
05:14Friends, the seismic wave is recorded in the receiving sensor
05:17originating from the depth of any planet.
05:20And when something strange is seen in these seismic waves,
05:24it tells us that there is something under the surface
05:28which is much different from the underground surface element.
05:32Not only this, but it can be studied on these seismic waves
05:36to find out what material it is coming from.
05:39Friends, when the model of the data sent by the Inside Lander was prepared,
05:43it was found that there is a layer of many stones under the surface of Mars,
05:48in which there are many big holes,
05:51and a lot of water is also filled in these holes.
05:55Now you must be thinking that how did this water reach here?
05:58So friends, just like the water on our earth goes under the surface of the earth,
06:02in the same way, there were many oceans on the surface of Mars thousands of years ago.
06:08And the water of these oceans has been stored under the surface of Mars.
06:13Now we just have to get this water out.
06:16But the thing to think about is how to get this water out?
06:20Because according to the model, this water is present at a depth of 10 to 20 km from the surface of Mars.
06:26But friends, the meaning of this problem is not that we are not going to get any benefit from this search for water.
06:31Because this time there was not much snow on Mars.
06:34Rather, the quantity of water in these holes is so much that
06:37it can form an ocean 1 to 2 km deep,
06:40through which the needs of humans can be fulfilled for centuries.
06:44The thing to think about is how to get this water out?
06:47Because to get the water out, it is very important to have 3 resources on Mars.
06:52First of all, we have to build a drilling tunnel on Mars, which is about 20 km deep.
06:58And this water can be taken up through this tunnel.
07:01But to drill on Mars, we will need a lot of powerful motors and energy supply.
07:07Apart from this, friends, making a motor that goes 20 km deep and brings the water up while fighting gravity is a very difficult task.
07:16But even if we make such a motor, then how will this motor be taken to Mars?
07:22And the biggest thing is where will it be given power supply?
07:26And think if we can arrange all these things in any way, then we will need a protected infrastructure.
07:32Because as we told you that there is a lot of radiation and bad environment on Mars.
07:38Because of which if the water is left open like this,
07:41then either it will fly away due to radiation or it will not be drinkable.
07:46Now the thing to see is how long scientists will reach the surface of Mars and start taking this water out.
07:52Do tell us what you think by commenting on this.
