In a first, Chandrayaan-2 maps abundance of sodium on Moon In a recent work published in The Astrophysical Journal Letters, researchers have reported that India’s Chandrayaan-2 has mapped the abundance of sodium on Moon for the very first time using its large area X-ray spectrometer, CLASS. Built at Isro’s UR Rao Satellite Centre in Bengaluru, CLASS provides clean signatures of the sodium line thanks to its high sensitivity and performance. The study finds that a part of the signal could be arising from a thin veneer of sodium atoms weakly bound to the lunar grains. Earlier, India’s Chandrayaan-1 X-ray Fluorescence Spectrometer (C1XS) had detected sodium from its characteristic line in X-rays which opened up the possibility of mapping the amount of sodium on Moon. The serene radiance that fills the vast expanse of a night sky is the reflection of sunlight from the Moon's surface, a major part of which is from the bright lunar highlands, Isro said, adding that the rock and soil samples that the Apollo 11 astronauts brought to Earth showed that these regions which are remnants of an ancient lunar crust, are mainly composed of silicate minerals in the group plagioclase feldspar series. “While these are common minerals found on Earth, lunar samples have a variety of the mineral that contain more of the element Calcium than Sodium (which is an alternative) following the general trend in compositional differences between Earth and Moon. A loss of volatile elements including alkalis like sodium and potassium on the Moon could be traced back to the time when Earth and Moon formed together in a Solar system that was young and fiery,” an Isro statement from October 7, reads. While successive laboratory investigations of the returned samples - Apollo, Luna and Chang'e - widened the range of compositions, the fundamental conclusions have remained, it added. “However, the returned samples are from a few specific regions of the Moon which do not necessarily represent the global lunar composition. Sodium is one of those elements that do not have a telltale signature in the visible or near-infrared wavelengths and has thus not been targeted via remote sensing observations. Chandrayaan-1 detected sodium, opening up possibilities of mapping it on Moon,” Isro said. These sodium atoms, Isro says, can be nudged out of the surface by solar wind or UV (Ultraviolet) radiation more easily than if they were part of the lunar minerals. “Also shown is a diurnal variation of the surface sodium that would explain the continuous supply of atoms to the exosphere, sustaining it. An interesting aspect that widens the interest in this alkali element is its presence in the wispy atmosphere of the Moon, a region so thin that the atoms there rarely meet,”
Even I visited it on the 1st day. I was shocked to see Godrej is such a big player in Aerospace industry. They got into it back in 2007 itseems.Being a student in Aerospace engineering and a propulsion enthusiast It was like a dream come true, Touching those used engines kept at display.
The point you mentioned about meeting with others. I totally agree with it. I think many others will also agree with it. Thanks for the wonderful videos sir. Lets keep the drama aside and only focus on good engineering.
@@GareebScientist yes. Sadly, talented people could' nt get into engineering or science careers, and engineers do all others sorts of things other than engineering, and most people in our country have no no idea about pure science careers..😢
I think sometimes it’s good to come out of one’s barrier even I used to do it never meet strangers and all I am a mathematician working as a consultant now but I feel that we learn a lot when we interact with strangers just a small piece of advice although you didn’t ask for it. 😊 And science is entertaining in itself look at everyday astronaut.
Bengaluru Space Expo was an eye opener. One of our Space Club team member got to Talk with Somnath Sir personally. For those who have visited, we definitely get to see 30 year old Indian supplier who provide critical component for our satellites. I personally got to talk with 2 ISRO scientists who have their startup incubation in IISc and they are veterans. The trend is positive. We will soon observe a boom in Space Industry just like what IT industry had witnessed back then.
Hi i totally agree with you. Aaj k time me privacy bhot high priority thing h. Even I am a member of the Chanel since I knew about that. But i am just a space nerd so I didn't interfere with any other things. You are definitely doing a great job i really appreciate it. Keep it up. One day we definitely meet but with proper appointment.
I like the way you work and that you demand privacy is totally natural. What you can probably do is have AMA sessions where you can answer general (non-personal) questions from your community. People that subscribe to you, as an additional service for paid subscription. Fan service is what Insta influencers do (that you call cancer), not asking you to do that, but you can definitely inspire children to take Space seriously. Keep doing the good work.
It's understandable you don't want to have much communication from someone you don't know-but I'd say you're doing this too formal. What you can do is you have your own panel or something like that in which engagement is purely knowledge/information exchange-in which you and others can benefit. Apart from that, somebody thinking you are their friend just because they watch your videos-is a feeling I'd understand too. But also know this, if some were to get a chance and talk space with you-that will be golden just because of shared passion. Even though there are many people out there with interest in space and yet not enough to have this type of shared experience and passion-which is just hard to come by even at this point. You responding to social media queries and convos is also much much appreciated. So thanks for everything-glad there's someone out there like you.👍
Seeing this video people will understand that there are countless number of subsystems and one can dedicate his/her entire 50-60 yrs of career to just develop a small but critical "sub-sub component". For people who ask everytime "how can I get into isro?!"
ha bhai , mein bachpan se akela akela rehta hun and now i love this feeling, socialisiation feels like a waste of time and very unproductive. although im worried this will create trouble once im married
I used to be your member but I left few weeks back but I really appreciate work of all scientists across globe. But on your community there is not much science, although you do explain science in very good and simple way. Suggestion : I appreciate your thinking that you won't get influenced that what viewers want to see, as you said in your Q&A you will do what you feel good. But don't you think being an engineer you have some responsibility to guide your followers into right path of science and force them to do thought experiment at least. now what they do is not your concern but when you are using contents of other scientists work to run your channel (not considering what your full time job is) I think it is time to pay it forward and inspire some mind to be next Nobel Prize winner.
