Since you asked, I tried my best to share my understanding from the web: Langmuir Probe is immersed into plasma and then a biased voltage is applied (varied from -12V to +12V with increment of 0.1V in case of RAMBHA-LP) across electrode (metal ball in this case), in return it catches the accelerated electrons. Because of absence of magnetic field and a significant atmosphere, Moon is like a body immersed in plasma, due to the solar wind. This plasma environment is one of the reasons for the electrostatic charging of the lunar surface. As the acronym RAMBHA mentions “Hypersensitive ionosphere and Atmosphere” that is nothing but the plasma. RAMBHA-LP is to measure the intensity of that plasma throughout the lunar day, the data shown here ( 10:05 ) has only three readings and that too of the same day within 3-4 hours duration, which was a little late than the morning at that place on the moon, so lesser number of electrons. The variation of number of electrons throughout the lunar day will provide us with charging conditions (electron density, ions density, electron temperature, plasma potential etc.) at the lunar near-surface, which is crucial for obvious reasons if we look into the future. The VI characteristics shown here shows only the measured data, the results (electron density, ions density, electron temperature, plasma potential etc.) are obtained by applying some well set algorithms.
Thanks for the explainer. Just some additional observations from the graph at a very basic level: 1. When the voltage is negative, the terminal attracts positive ions. As voltage is increased, this flow seems to accelerate rapidly, indicating proximal availability. At -11V, it appears that saturation occurs. This may indicate probe conduction limit. 2. At -2V, capture of ions stops. As voltage goes to zero, negative ions are captured. So, some must have a charge in excess of -2V 3. As voltage increases in the positive domain, there is a steady increase in capture, indicating lower density of negative ions. As voltage increases the capture current increases, indicating that saturation is not reached.
Very thanks for the reply@@ravinagaraj7003 This made me look at the graph more deeply. Further thanks for the observations. Here's what I observed in the graph ( 10:05 ) from my understanding from the searches on the web: 1) When the probe voltage is negative the cations are attracted towards the probe, more negative voltage (about -12V to -9V in case of 16:20 UTC curve) leads to accumulation of ions forming a sheath, perhaps that represents the saturation of ions in the graph provided. Further when voltage increases, i.e., becomes less negative, the sheath thickness reduces, that results in the abrupt increase in ionic current. Also, as the sun rises further in the sky, the plasma potential is expected to increase, which will result in increased slope of the curve in the right of floating point (where graph cuts the voltage axis). If the continuity of graph persists, which is expected to be so, there is going to be more ionic saturation at less negative probe potential (as shown by the 16:20 UTC curve). 2) At about -2V, I would rather say there is a balance between flow of cations and electrons (might be some anions too) which resulted in net zero current. [[This phenomenon I could not understand but my best guess is the high velocity of negatively charged particles which do not get deflected by the less negative potential of the probe.]] 3) Your observation of steady increase in electron capture is in line with the ISRO's statement- "...the plasma encompassing the lunar surface is relatively sparse, characterized by a number density ranging from approximately 5 to 30 million electrons per cubic meter." This is expected to change as sun progresses in the sky as I have mentioned above.
just basic principle of how RAMBHA-LP works (BASED ON WHAT I UNDERSTOOD) :- Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere - Langmuir Probe (RAMBHA-LP) was basically a langmuir probe, which is a device used to measure the properties / nature of given plasma such as : 1. electron density 2. ion density 3. electron temperature (in this case, it is plasma at moon's surface ) COMPONENTS INVOLVED IN LANGMUIR PROBE :- 1. single/two electrodes 2. a primary circuit to apply voltage to electrodes 3. a detector to detect even minute electric current. WORKING PRINCIPLE :- it works by placing an electrode or two electrodes in the plasma, basically electrodes should be placed such that plasma should be in between electrodes OR in some cases, one electrode is placed in the plasma and the surface of device acts as other electrode. and there will be a primary circuit where voltage is applied between two electrodes. and due to plasma / ion's, the circuit is closed, enabling the current to flow between electrodes. here, the movement of ions of plasma, due to applied voltage completes the circuit. THE GRAPH THAT ISRO SHOWS IS THE GRAPH OF APPLIED VOLTAGE BETWEEN ELECTRODES VS CURRENT THROUGH PLASMA AT MOONS SURFACE, basically V vs ( I ). 1. 1st case, here a -ve voltage is applied to electrode and +ve ions of plasma accumulate around the -ve ly charged electrode forming a layer of +ve ions. ion current density J(i) = ion current I(i) /ion collection area A ion collection area A, is the area of -ve charged electrode that is exposed to plasma. using some other complex equations(which i doesnt know 😅), we can get values of ion density and ion current and temperature. similarly, 2. 2nd case. here, electrode is +ve ly charged and electrons/ negative ions of plasma gets accumulated around the +ve ly charged electrode, forming a layer of -ve charged electrons/particles. and similarly we can determine the values of electron density, electron temperature GRAPH OF V vs I :- even this graph has different parts of it. 1. FLOATING POTENTIAL when V is taken on X-axis and I is taken on Y-axis, the graph cuts X-axis at some point. the point at which graph cuts X-axis is called FLOATING POTENTIAL, it is where electron and ion currents are equal. 2. ION SATURATION CURRENT it is the part of graph before it meets X- axis (FLOATING POINT). IT determines the density of ions 3. PLASMA POTENTIAL the part of curve before electron saturation current region 4. ELECRTON SATURATION CURRENT REGION it determines the electron density. CORRECT ME IF THERE IS ANY WRONG IN THIS. THIS IS JUST BASED ON MY OWN UNDERSTANDING.
Love the way GS you inspire the next Gen! Lets keep aiming higher and higher for we have a whole cosmos to explore! After CY3 and AL1 I am hoping we get to see SY1 soon, it’s time we gave our next door sister planet Venus some love. Lot to learn there!

Sir one thing, scientists use Atomic spectra to identify the different elements of periodic table. Not all elements emit visible spectra so, spectra is different from light as you mentioned in video. (During LIBS discussion).
After watching this channel since Corona Days , I have become fan of Astronomy and Space Science. This efforts are highly appreciable. Superb work done by "Team Garib Scientist". ✋ High five ✋
The point where i really appreciate your work is to read the comments and face palm every time people asking for B-roll for the mission. Probably you have to still deal with paying members who would have such witless queries. I would just ban these people to eternity. This mission was done on such low budget that we had any real science done is good ROI (even if we didnt find water). The obsession with Instagram type PR images is insane. When ISRO gets half the budget NASA gets, you can expect these things. Other alternative is private players do these missions (like Spacex) where PR is important for marketing.

After 14 days pragyan: isro k papa utho subah ho gyi vikram: haa (still sleeping) pragyan:dekho cy2 ka orbiter upper se ja raha h (bapuji) vikram:haa bapuji uthh gaya
I think both of the instruments will survive because they were already in the space where the temperature is 2-3 Kelvin. That is the minimum temp can reach so instruments will survive.
There is a catch Sir; The temperature of space, often referred to as the temperature of the Cosmic Microwave Background (CMB), is approximately 2.7 K. However, it's crucial to understand that "temperature" in the vastness of space doesn't function in the same way as it does in an atmosphere. Space is mostly a vacuum, so there are very few particles to transfer heat. When we talk about the 2.7 K temperature, we're referencing the energy of the photons from the CMB rather than the temperature of matter in the way we typically understand it. That's why It will not cool the spacecraft in space as the same manner it will cool in the Earth in same temperature. Now, A question might arise, We know moon doesn't have atmosphere, So how heat is conducting there. So, here there is a simple misconceptions, Though moon doesn't have atmosphere like Earth still, The Moon has a very thin and tenuous atmosphere, called an exosphere. Okay, It may not play a crucial role in conducting heat, Still Moon has a lunar surface, and if you see the CHASTE results, It shows that, moon soil is highly insulating, So it will hot faster when sunlight falls and also it will cold faster to extreme temperatures more than -170°C when sun goes. That's why though the moon has higher temperature than space, It's critical to stay things alive without Any kind of thermal generators. Anyway, It's a made in India product, So we can hope for the best that, Both of them would awake again.
I have a doubt jab light emmit hogi tab interference bhi to hoga and suppose waves ka anti addition hua ya +ve addition hua and resultant wave kisi 3rd element jo vaha hai bhi nahi uske emmision spectra se match kar rahi hai to libs ko lagega ki 3rd element present hai but reality me to ye 2 and more elements ke waves ke combined result hai , so how does LIBS cater this problem
The MEMS data is interesting. Neither reading is centered at 0.0, which may indicate calibration error. The signal in red shows a maximum amplitude of 0.002 ms2 with center (rest) at -0.1186. Shape of the signal indicates a shock and dampening across 3 seconds roughly. The signal in blue shows a spike of 0.01 ms2 and a signal of about 0.002 ms2, centered at 0.019. By calibrating the MEMS against the rolling sounds of Pragyan, it should be possible to tell quite a bit about the other signal. Not sure what caused the shift in center (rest). Note the center point shift is an order of magnitude greater than the signal measured.
When the lander did the hop, the dust that arouse, will it not hamper the solar panel performance if the rover has ability to awake after lunar night? Do u think the temp of 50°c above or on the ground wasn't affected by the exhaust nozzle of the engine?
The rover was far enough for the HOP, and the moon soil is highly insulating and the CHASTE experiment is done after almost 1 day after landing, So we can't say, Thruster nozzle will cause it still, We can't even neglect it, ISRO have a more specific answer to this.
I thought little bit about what can be the benefits of taking the tiver back into the lander.. I feel that the radiation heat loss from the rover could have been limited little bit more with this, and also it could have been a test for future missions where the rover can bring little bit of regolith into the lander, and the lander can bring it back to earth. But that's a long way to go..
While measuring the temperature using chaste, the amount of moon dust displaced by the cryo engine exhaust also the thermal discrepancy will be there or not? Is it feasible to take the readings just below the lander? Also the thermal conductivity of the moon soil can be relevant in this case?
GS- One suggestion is to make a video on observations and discoveries made by Astrosat One such was AUDfs01 which was phenomenal would love to have a detailed video on it as the observatory is really underrated! I know you have made a technical video about it but the science which it performed there is still not talked off on any media or yt channel so far Love your content as always ❤
One observation regarding the rover turning on its vertical axis , none of the wheels seem to be steering left or right to achieve this turn. Then how the turn is being achieved ? What is the design here?
Very informative, thanks. I know there is space collaboration between friendly nations, but please help me understand why we share such vital information/data so publicly making it more easier for all to land at some point at lower cost and more accurate data points. Should this not be classified.
"Hop" would have raised dust. Would that impact the Pragyan Rover, as it did not travel much far. And as moon gravity is low, dust settlement would be slow and range would be more
I want to know why we landed in a crater ... As these structures are created by foreign bodies, which may contain a lot of foreign substances..(from mars or earth) Natural Regolith ko kaise inspect kr paenge hm ..?
reddit me mai ek post me dekha, "chandrayaan 3" ka logo me, the number 3 looks like 2 hops. Idk if the hop was pre planned or not, we will never know!!

IN OUR LABORATORY, We use Langmuir Probe to determine ion density, ion temperature, electron temperature of a plasma in a controlled environment. This gives us the characterization of plama. We make a vacuum, introduce a controlled amount of gas and then deploy a potential difference or energy, to Ionize the gases to form plasma. My catch is, moon does have just 1/6th of Earth's gravity but it's still gravity, and hence it's likely to have a gentle atmosphere whose pressure is times less than that of earth. So, 1. We got a very less amount of gas, 2. We got energy from a blazing and unfiltered sun, therefore we are likely to have a kind of plasma in moon's atmosphere 😬
Why my comment no showing me😢 My comment is BHARAT🇮🇳 ALWAYS MAKES HISTORY LIKE INDIA🇮🇳🧡🤍💚 MAKES G20 INTO G21 I FEEL GREAT HAS INDIAN KID OF BHARAT🇮🇳MATA😊☺❤❤❤
Chandrayan leave it's heat shield before leaving earth's atmosphere. It have survive more than a month in space. So why it's survival possibility is questioned? Is moon more cold than space?
Can someone pls help me understand this - C3 will go offline after 14 days because it'll be night for next 14 days (no solar charging) but after the 14 nights, when the sun comes back up, will C3 start charging and move again? Why did ISRO say that it will be active only for 14 days? Did I misinterpret their statement ?

Since you asked, I tried my best to share my understanding from the web:
Langmuir Probe is immersed into plasma and then a biased voltage is applied (varied from -12V to +12V with increment of 0.1V in case of RAMBHA-LP) across electrode (metal ball in this case), in return it catches the accelerated electrons.

Rambha ho ho sambha ho ho
just basic principle of how RAMBHA-LP works (BASED ON WHAT I UNDERSTOOD) :-
Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere - Langmuir Probe (RAMBHA-LP) was basically a langmuir probe, which is a device used to measure the properties / nature of given plasma such as :
1. electron density
2. ion density
3. electron temperature
(in this case, it is plasma at moon's surface )
COMPONENTS INVOLVED IN LANGMUIR PROBE :-
1. single/two electrodes
2. a primary circuit to apply voltage to electrodes
3. a detector to detect even minute electric current.
WORKING PRINCIPLE :-
it works by placing an electrode or two electrodes in the plasma, basically electrodes should be placed such that plasma should be in between electrodes OR in some cases, one electrode is placed in the plasma and the surface of device acts as other electrode. and there will be a primary circuit where voltage is applied between two electrodes. and due to plasma / ion's, the circuit is closed, enabling the current to flow between electrodes. here, the movement of ions of plasma, due to applied voltage completes the circuit.
THE GRAPH THAT ISRO SHOWS IS THE GRAPH OF APPLIED VOLTAGE BETWEEN ELECTRODES VS CURRENT THROUGH PLASMA AT MOONS SURFACE, basically V vs ( I ).
1. 1st case, here a -ve voltage is applied to electrode and +ve ions of plasma accumulate around the -ve ly charged electrode forming a layer of +ve ions.
ion current density J(i) = ion current I(i) /ion collection area A
ion collection area A, is the area of -ve charged electrode that is exposed to plasma.
using some other complex equations(which i doesnt know 😅), we can get values of ion density and ion current and temperature. similarly,
2. 2nd case. here, electrode is +ve ly charged and electrons/ negative ions of plasma gets accumulated around the +ve ly charged electrode, forming a layer of -ve charged electrons/particles. and similarly we can determine the values of electron density, electron temperature
GRAPH OF V vs I :-
even this graph has different parts of it.
1. FLOATING POTENTIAL
when V is taken on X-axis and I is taken on Y-axis, the graph cuts X-axis at some point. the point at which graph cuts X-axis is called FLOATING POTENTIAL, it is where electron and ion currents are equal.
2. ION SATURATION CURRENT
it is the part of graph before it meets X- axis (FLOATING POINT). IT determines the density of ions
3. PLASMA POTENTIAL
the part of curve before electron saturation current region
4. ELECRTON SATURATION CURRENT REGION
it determines the electron density.
CORRECT ME IF THERE IS ANY WRONG IN THIS. THIS IS JUST BASED ON MY OWN UNDERSTANDING.

Plz if ho paye to jaldi jaldi video's dala kro
Aapke channel pe roj check krta hu koi new video upload ki ya nai
❤
Bro🫡 for your knowledge and explanation
Love your video ❤ keep sharing thank you
I think both of the instruments will survive because they were already in the space where the temperature is 2-3 Kelvin. That is the minimum temp can reach so instruments will survive.
There is a catch Sir;
The temperature of space, often referred to as the temperature of the Cosmic Microwave Background (CMB), is approximately 2.7 K. However, it's crucial to understand that "temperature" in the vastness of space doesn't function in the same way as it does in an atmosphere. Space is mostly a vacuum, so there are very few particles to transfer heat. When we talk about the 2.7 K temperature, we're referencing the energy of the photons from the CMB rather than the temperature of matter in the way we typically understand it.
That's why It will not cool the spacecraft in space as the same manner it will cool in the Earth in same temperature.
Now, A question might arise, We know moon doesn't have atmosphere, So how heat is conducting there. So, here there is a simple misconceptions, Though moon doesn't have atmosphere like Earth still, The Moon has a very thin and tenuous atmosphere, called an exosphere.
Okay, It may not play a crucial role in conducting heat, Still Moon has a lunar surface, and if you see the CHASTE results, It shows that, moon soil is highly insulating, So it will hot faster when sunlight falls and also it will cold faster to extreme temperatures more than -170°C when sun goes. That's why though the moon has higher temperature than space, It's critical to stay things alive without Any kind of thermal generators.
Anyway, It's a made in India product, So we can hope for the best that, Both of them would awake again.
We cannot click earth image from rover or lander right ? Because camera is foward pointed.
Yes down pointing
You are amazing scientist. I really appreciate your videos for knowledge, voice, simplicity.
Thanks. Keep it up.. 😊
I have a doubt jab light emmit hogi tab interference bhi to hoga and suppose waves ka anti addition hua ya +ve addition hua and resultant wave kisi 3rd element jo vaha hai bhi nahi uske emmision spectra se match kar rahi hai to libs ko lagega ki 3rd element present hai but reality me to ye 2 and more elements ke waves ke combined result hai , so how does LIBS cater this problem
You can split the incoming spectra NA. Check paper in sources in description
The MEMS data is interesting. Neither reading is centered at 0.0, which may indicate calibration error. The signal in red shows a maximum amplitude of 0.002 ms2 with center (rest) at -0.1186. Shape of the signal indicates a shock and dampening across 3 seconds roughly. The signal in blue shows a spike of 0.01 ms2 and a signal of about 0.002 ms2, centered at 0.019. By calibrating the MEMS against the rolling sounds of Pragyan, it should be possible to tell quite a bit about the other signal. Not sure what caused the shift in center (rest). Note the center point shift is an order of magnitude greater than the signal measured.
Controlling mind is key of success.
Ramba is well explained by GetsetflyScience
Bhai kitne din wait karwate ho, was eagerly waiting
Thnx for the brief explanations
END IS LITRALLY EPIC "AAP DEKH LO BYE"
How can we study the craters on Moon via unmanned rover? Ingenuity like or a crane like payload maybe? Any ideas/comments?
Agar andar hai tho charge nahi hoga bolraha, tho 1 month lander ke andar hi tha fir bahar kaise nikal gaya bina charge ke
Can we hover over the moon using lander like a drone and do something crazy by capturing the whole moon ?
Not whole but it ie possible
When the lander did the hop, the dust that arouse, will it not hamper the solar panel performance if the rover has ability to awake after lunar night?
Do u think the temp of 50°c above or on the ground wasn't affected by the exhaust nozzle of the engine?
Although I don't know how far can moondust go after a hop by lander but I think rover was far enough for that
The rover was far enough for the HOP, and the moon soil is highly insulating and the CHASTE experiment is done after almost 1 day after landing, So we can't say, Thruster nozzle will cause it still, We can't even neglect it, ISRO have a more specific answer to this.
We'll know on 22nd September
Nothing to image right all sleep
Good night..... After too much of hardwork
I thought little bit about what can be the benefits of taking the tiver back into the lander.. I feel that the radiation heat loss from the rover could have been limited little bit more with this, and also it could have been a test for future missions where the rover can bring little bit of regolith into the lander, and the lander can bring it back to earth. But that's a long way to go..
Bhai aap 3d modeling kese karte ho btao bhut acche se kr lete ho application name batao please 🙏💕
Blender probab
Muje yehi lag rha tha bhai ki ye Blender me bna hai but kafi accha bna hai 💕
Goodnight vikram and pragyaan...... ❤
Good night both.
9:01 are bhai wo log moon ko mother bol rhe the vikram ko nahin 😂😂
@6:19 isnt this angstrom unit?
Even vikram lander got some solar panels , why should we not develop technology to charge pragyan inside lander during night !!
While measuring the temperature using chaste, the amount of moon dust displaced by the cryo engine exhaust also the thermal discrepancy will be there or not? Is it feasible to take the readings just below the lander? Also the thermal conductivity of the moon soil can be relevant in this case?
Please make video on what is the reasons to not wake up ch3
GS-
One suggestion is to make a video on observations and discoveries made by Astrosat
One such was AUDfs01 which was phenomenal would love to have a detailed video on it as the observatory is really underrated! I know you have made a technical video about it but the science which it performed there is still not talked off on any media or yt channel so far
Love your content as always ❤
One observation regarding the rover turning on its vertical axis , none of the wheels seem to be steering left or right to achieve this turn. Then how the turn is being achieved ? What is the design here?
Love your work bro..one day tum ko sab janega...puri indiaaa dekhna
Very informative, thanks. I know there is space collaboration between friendly nations, but please help me understand why we share such vital information/data so publicly making it more easier for all to land at some point at lower cost and more accurate data points. Should this not be classified.
"Hop" would have raised dust. Would that impact the Pragyan Rover, as it did not travel much far. And as moon gravity is low, dust settlement would be slow and range would be more
Is it possible that the Au stands for angstrom unit?. It is usually used to describe wavelengths
That's already on x axis
I want to know why we landed in a crater ...
As these structures are created by foreign bodies, which may contain a lot of foreign substances..(from mars or earth)
Natural Regolith ko kaise inspect kr paenge hm ..?
Wow no one replied 😅
Consecutive Banger Videos! Nice.
क्या isro न्यूक्लियर प्रोपेल्ड रॉकेट पर काम कर रही है?
Respect to ur knowledge & passion ❤.
reddit me mai ek post me dekha, "chandrayaan 3" ka logo me, the number 3 looks like 2 hops.
Idk if the hop was pre planned or not, we will never know!!
hmmm nah bro doubt
@@GareebScientistBRO THIS MAKES ME WONDER NOW KYA YEH SACH HOGA PLS BATA
@@suyashsingh8111pre planned tha bhai lekin public nhi kiya
@@jatin_krishna hmm
why isro do not use nuclear energy (RTG) to keep vikram lander functionable and also to power the rover and lander.
Thanks a lot for always being informative to me
Namaste gareeb scientist ji! Mene aapki videos dekhi aur bhot inspired hui ...isro ke bare me aur jankari lene ke liye...
Abhi 2 din me mere college me isro ko tribute de rhe hai by hosting an event jisme humme isro ke bare me bolna hai...
I wanted... ki me apne college mates ko in short bta pau about the PATHBREAKING things isro did.
But i dont have enough time to get such good animations...
Agar aapko dikkt na ho to me aapke animations mang skti hu? without the watermark?
I dont mean to be unethical and it will be only used for this sole purpose only....
aapko to bhot knowledge hai... to aap kya meri help kr skte hai?
to include more points to the things you thought were truly pathbreaking that isro did and no one else thought of
and usse kya faide hue/ho skte hai humme!
Maine to kabhi socha hi nhi ki ramo ko fold nhi Kiya Jaa sakta mujhe pata tha ki agar isro ramp deploy karne ki technology rakhta hai to its easy for them to fold that as well
Me too
Why black& white picture??
IN OUR LABORATORY, We use Langmuir Probe to determine ion density, ion temperature, electron temperature of a plasma in a controlled environment. This gives us the characterization of plama.
We make a vacuum, introduce a controlled amount of gas and then deploy a potential difference or energy, to Ionize the gases to form plasma.
My catch is, moon does have just 1/6th of Earth's gravity but it's still gravity, and hence it's likely to have a gentle atmosphere whose pressure is times less than that of earth. So, 1. We got a very less amount of gas, 2. We got energy from a blazing and unfiltered sun, therefore we are likely to have a kind of plasma in moon's atmosphere 😬
I know people who can work with Langmuir probes on a daily basis. Just in case you need contact.
I wonder if the solar panels on lander and rover got damaged from lunar dust during the Hop test 🤔...guess we will know the answer on 22 September.
Why my comment no showing me😢
My comment is
BHARAT🇮🇳 ALWAYS MAKES HISTORY LIKE INDIA🇮🇳🧡🤍💚 MAKES G20 INTO G21 I FEEL GREAT HAS INDIAN KID OF BHARAT🇮🇳MATA😊☺❤❤❤
Chandrayan leave it's heat shield before leaving earth's atmosphere. It have survive more than a month in space. So why it's survival possibility is questioned? Is moon more cold than space?
Can a drone fly on Moon ?
3:35 piche zada aya hai pahele wo do gaddhen nhi dikh rhen then ab dikh rhen hain
Can someone pls help me understand this - C3 will go offline after 14 days because it'll be night for next 14 days (no solar charging) but after the 14 nights, when the sun comes back up, will C3 start charging and move again? Why did ISRO say that it will be active only for 14 days? Did I misinterpret their statement ?
It will depend on many factors let's see that today
Is that emission of light(LIBS), while cooling down due to jumping of electrons from higher energy state to lower energy state ?
your video is very amazing and your explnation is very uniqe & please explain the japanease moon mission
Koi RAMBHA explain kardo
Sir please tell me BSNL and chandrayan 3 ka connectivity kuch story he?
Please make video on retro reflector in chandrayan 3
❤ awesome analysis 👍😊
2 point deep nhi malum pda to hme explain bhi nhi kiya wow, 🙏😍
Aur aajkal ke media wale kuch bhi bakkk dete h, moon pe alien mila 🤦♂️😜
