This scientific masti series is really nice😅

❤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

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.

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.

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

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

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

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 💗💗💗

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

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!

Loved it - You are amazing person !!! 🙏

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

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

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 ❤️

Your work is to appreciated ❤❤❤❤

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 ✋

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

Love your video ❤ keep sharing thank you

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

Kya kya bata daala... maza aa gya ⭐

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 😊

Respect to ur knowledge & passion ❤.

Bhai kitne din wait karwate ho, was eagerly waiting

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

Beautiful! Thank you!

This guy deserve 100M subscribers

This video is historic for ur channel

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.

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

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...😊

Grt vdo🙏🙏🙏🙏🙏

Love your content

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

Bro🫡 for your knowledge and explanation

❤ awesome analysis 👍😊

Thnx for the brief explanations

Thanks a lot for always being informative to me

This is awesome

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 ❤

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

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.😊

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.

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

Mast video, informative 💯❤

Thank you 🙏

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).

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

Consecutive Banger Videos! Nice.

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!!!

Thanks for the info👍

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

Your video explaining very good knowledge ☺️

Nice Video Sir 🙏

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।

nice video sir...

best explanation.

grate bro❤

Very nice explanation 👍🏽

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😊☺❤❤❤

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

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

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

Jai Hind Jai Bharat🙏

Hello sir.. love to see you .

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 ❤

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.

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

Controlling mind is key of success.

The way he said bye In the end 😂😂

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?

♥♥

Sir. One question. Why tip of launching rockets /vehicles are kept round smood surfaced instead of conical pin point?. While pointed head reduces more friction. . Any specific reason for this??

END IS LITRALLY EPIC "AAP DEKH LO BYE"

Thanks for the great videos. I have a query. So while landing, the lander would obviously pop up dust. So how are the cameras protected in this case ?? A similar doubt had cropped up for NASA's Mars rover too looking at the turbulent atmosphere there. Thanks in advance 🙏🏻

Vedio upar upar se samajh aya but maja bhi aya

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

Jai Hind 🇮🇳

Ramba is well explained by GetsetflyScience

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..

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.

Thanks for the video 🚀 I was waiting for this summary video regarding whole expmt. Just fun... In one of a WIRED video a neurosurgeon answered a twitter question by saying neurosurgeon is more sophisticated than Rocket science any thoughts?

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

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 🤦‍♂️😜

Nice

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....

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?

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.

Sir kya wheels p isro mark h kya moon surface p logo print k liye

Bro can you make video on different microcontrollers used in launch vehicle and in space industry?

Mstiiii

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

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

Please make video on retro reflector in chandrayan 3

Is that emission of light(LIBS), while cooling down due to jumping of electrons from higher energy state to lower energy state ?

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?
