[@panoptical]

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.

[@ravinagaraj7003]

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.

[@panoptical]

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.

[@prakharmishra3000]

Rambha ho ho sambha ho ho

[@syamanth988]

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.

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.

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.

[@SuniL.KrishnA]

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??

[@kishorevenugopal6191]

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..

[@GareebScientist]

That's already on x axis

[@pradyutsarma8021]

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 😬

[@GareebScientist]

You can split the incoming spectra NA. Check paper in sources in description

[@dpkchohan]

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.

[@Shashwata]

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.
