Man really said "Ye video utna high nhi hoga" , Then proceeds to give an absolute best.

❤Save this man at any cost ❤️ thank you for your knowledge!! Pls support him and donate him 🙏🏻

First comment .......I'm a 8th class student following you for 2 years your videos has helped me a lot !! I won the interschool science quiz because of your videos i aim to be a space scienctist at isro and your videos has helped me a lot to gain knowledge you are a true sigma

This scientific masti series is really nice😅

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.

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.

Mother watching a child having fun That clip was really awesome loved that❤

RAMBHA LP ions. Detect krta Hai Jo ki moon ke surface pe sun ki rays ke Karan ionised hoke released hote Hai isse presence of electron detect hoga Jesse ki kiss bhai deta ko send ya receive krne me Jo electron difference ke Karan disturbance Ata Hai usko Hatay ja sake . PLEASE READ THIS

MUJE GAREEB BHAI KE BAARE ME AUR KUCH TO NHI PTA PAR GAREEB BHAI DIL KA AMEER TO PAKKA HAI THANK YOU BHAI

The science u have taught me has inspired me to become a space scientist...I am in 10th now...hopefully in some years I should be in isro...THANKS 💗💗💗

I love your ... attitude towards sharing knowledge....Hatsoff

Why he is so underrated bruhh?really?? People like dhruv rathee are so overrated but real people like gareeb scientist are still not so famous

Thank you so much man. Really appreciate these videos. You're an absolute gem. 🙏🏽

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 I love your videos , they are a good source of knowledge for the people who has interest in these field

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

Loved it - You are amazing person !!! 🙏

Sir apki videos kafi achi hoti h or kafi mehant krte h aap apni videos me I hope your channel will get 1 million subscribers ❣️

I just love your videos i have learnt many things from your videos ❤️

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 ✋

Your work is to appreciated ❤❤❤❤

Love u man..keep posting videos on regular basis. We need more n more...superb bro

I have only one criticism about the data. There is no error bars in the plot. There should be some error bars as they represent scientific data.

I had this question: why rover was not pulled back inside the lander; you have now explained the reason...it was so obvious! Thank you.😊

Aap apna audiance k sath jo honestly knowledge share karta ho uske leya Thanks Sir Jis topic ki knowledge nahi bol deta ha Baki YT k jasa ni faltu ka Gyan dena lg jayaga

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).

This guy deserve 100M subscribers

Grt vdo🙏🙏🙏🙏🙏

Why did they not record the hop on the rover? That would have looked so much more awesome.

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.

Make video about 100 ton methalox engine of India and its use in NGLV, and detailed schedule of Gaganyan program.

Kya kya bata daala... maza aa gya ⭐

Bro🫡 for your knowledge and explanation

10:15 Mujhe yeah Current aur Bias Voltage wala graph dhek ke DIOD ka graph yaad agaya.... Forward Biased and Reverse Biased

अनेक अनेक धन्यवाद।🙏 आपके स्पष्टीकरण का जवाब नहीं। कहां 1 चंद्रदिवस का सोच के चले थे, अब महत्वाकांक्षा ही बढ़ा दी। कोई नहीं, अब जो कुछ भी result मिलेगा, वो बोनस होगा। बस एक सुझाव था इसरो अगर नाभिकीय ईंधन की ओर थोड़ा ध्यान दे। संभवतः विक्रम की आयु महीनो या वर्षों हो सकती थी।

Love your video ❤ keep sharing thank you

Thanks a lot Sir for explaining these. Your videos are amazing. Thanks again from TN..

Great Video.... I trust you... Aap jo bole ke mujhe 1 ya 2 level jyada clear hona chaiyae..... Was op.... ❤❤❤🙏🙏🙏

This video is historic for ur channel

Thnx for the brief explanations

Video ka wait kr raha tha every time CY3 ki har new experiment per, ki bhai aaye samjay ki kya kya result nikla, ....kitna easy samjhate ho yar...😊

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😊☺❤❤❤

I was so used to your "gyan ki garibi sabse badi...." Even the hyper fast "thanks to chaitanya kunte, avinash agrawal..." ; that my mind filled that void after the video ended!!!

No question is stupid it's always good to educate.

Bro agar aap in-situ and remote sensing jaise general terms explain kar sakte ho while narrating, toh please yeh niche short forms bhi bataa diya karo. Jaise ki chaste, libs, rambha, ilsa etc. Bas ek baar inka long form bol doge toh usse bhi samajh aa jayega bahut kuch. I know I might sound a little dim witted right now, but this little thing can go a long way in increasing engagement of your videos in this attention economy. It’ll also make you come across as a better science communicator. I love listening to Neil DeGrasse Tyson for this very reason. He hardly ever uses such jargon, or if he has to, he makes sure to briefly explain the jargon before moving ahead. Btw, I’m a fan of your channel. It’s just some constructive feedback in good faith.

Love you bro❤ 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 ❤

7:45 Love how India is highligthed with lights on Earth

Goodnight vikram and pragyaan...... ❤

Ramba is well explained by GetsetflyScience

You are amazing scientist. I really appreciate your videos for knowledge, voice, simplicity. Thanks. Keep it up.. 😊

Thanks a lot for always being informative to me

The way he said bye In the end 😂😂

Good night..... After too much of hardwork

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.

High on content, good and simple language explanation. Showcasing emotional side of science fan very good. Your commentary is good and Hindi as well ( looks like you are from Southern side). Started watching your channel few months back. Now a Fan also follow you in Twitter (Now X). Good work keep going 😊

Controlling mind is key of success.

Consecutive Banger Videos! Nice.

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 🤦‍♂️😜

We cannot click earth image from rover or lander right ? Because camera is foward pointed.

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

Can we hover over the moon using lander like a drone and do something crazy by capturing the whole moon ?

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.

This is awesome

Even vikram lander got some solar panels , why should we not develop technology to charge pragyan inside lander during night !!

Respect to ur knowledge & passion ❤.

Bhai kitne din wait karwate ho, was eagerly waiting

How can we study the craters on Moon via unmanned rover? Ingenuity like or a crane like payload maybe? Any ideas/comments?

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?

❤ awesome analysis 👍😊

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..

your video is very amazing and your explnation is very uniqe & please explain the japanease moon mission

Your video explaining very good knowledge ☺️

nice video sir...

Nice Video Sir 🙏

END IS LITRALLY EPIC "AAP DEKH LO BYE"

Vedio upar upar se samajh aya but maja bhi aya

kuch bhi rahe ch3 chand pe reach hua saab kuch ,working condition the vahi sun kr maza agaya proud hua saab kuch details public domain me nhe daal skte hai jitna jaruri hai utna hai public domain daala ,jyada raja harish chandra India aab nhe krta....

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 ..?

Considering that lander has only cryogenic fuel, the rover has pure electronics. These devices are put to sleep state and no active charge is flowing. I am 90% sure that the lander and the rover will stay alive for the subsiquent many sunrises and sunsets on the south pole. Even the cameras are CMOS, so we should be able to see all the activity. Some instruments might go haywire but should bounce back. I believe, that the lander 90% rover 75% instruments 60% survival rate and full reactivation on 22nd September. The only problem is the battery section. If it survives, everything else should do. Lets pray to Shri Ganesha for the Chandrayaan 3 successful awakening :)

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.

Love your content

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 😬

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 ❤

Beautiful! Thank you!

Love your work bro..one day tum ko sab janega...puri indiaaa dekhna

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?

Yaar Suddenly aise Bye kon bolta h, Aisa lga ki achanak se heart beat ruk gya ho.😅

Jai Hind Jai Bharat🙏

"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

Mast video, informative 💯❤

Hopefully Vikram and Pragyan will survive ❤

Very nice explanation 👍🏽

Thanks for the info👍

Is it possible that the Au stands for angstrom unit?. It is usually used to describe wavelengths

♥♥

Jo ap bole ki pragyan ko andar dalne ke ban solar is not working but landar his charj to solar and wireless charging is saporting to pargayn rovar and charger ...

Thank you 🙏

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.

best explanation.
