Unnoticed Outcomes of chandrayan-3

burns the midnight oil on Earth, waiting to hear again from Vikram & Pragyan, principal investigators of instruments on the two have begun sifting through data for new findings 
Among many things the global scientific community is expected to learn from Vikram and Pragyan’s work before they go to sleep is new knowledge about the lunar soil, which will be useful for future missions, including ambitious projects aiming to send humans back to #Moon.
“It would have been easy if there was a way we could know if they would wake up, but we have to wait and see how systems behave after Sunrise,” Isro chairman S Somanath said 

Sunrise on the Moon was expected early Wednesday, the Sun's elevation angle will be at 0° early in the day and reach a maximum of around 13° angle by the end of the day. 

The optimal Sun elevation angle for systems to work would be 6° to 9°. But the temperature has to rise above a certain threshold. For the wake-up, we need power generation and temperature on the elements on Vikram and Pragyan to meet certain criteria… 

We should know something by September 21 or 22. If they wake up, it’ll wake up during this time,” M Sankaran, director, of UR Rao Satellite Centre,

Multiple Isro scientists said #Vikram & #Pragyan waking would be a bonus and that data sent when they were awake is expected to give new info given that all earlier in situ experiments were carried out in the equatorial region of #Moon. 

A lot of data has been collected but outcomes will take several months, even a couple of years. There is anticipation that our data will lead to some new things. And if systems wake up again, there’ll be more data, which is good,” Sankaran added. 

Physical Research Laboratory (PRL) director Anil Bharadwaj said teams were looking into datasets from instruments studying the surface, seismicity, temperature, elements, profile of temp beneath the surface, and regolith properties such as how fluffy, loose, or grainy it is. 

There are many parameters being studied. Our observations have the potential to give new information about the topsoil…

We can very clearly see rover movement paths being created, images of the landing site vicinity & rover movement site show grooves of the rover are about a centimeter, the lander legs going inside, suggesting loose soil. The soil will become compact as one goes deeper,”
That part we need to understand. How much is topsoil (regolith) and where it gets compact? There are previous conjectures about the features, and how they can retain signatures despite having loose soil 
There’s information built into observations that are carried out, we have to look at multiple parameters, and no one thing will tell us these things. These studies will be carried out,”

Space Application Centre (SAC) director Nilesh M Desai said: “One of the things we had targeted while planning the mission was whether ice could be found on crater rims 
To know more we need to study the rover data. It depends on where the rover has moved, what kind of data it has found when it was close to a crater 
Information about lunar topsoil
Pragyan, whose rear wheels are embossed with the national emblem & Isro logo, has been unable to leave a “clear” imprint of the two, which is a good sign as it gives a new understanding of the properties of the soil in the south pole region

New information about the soil in the south pole region, which is a target for multiple future missions as it holds the potential of discovery of water, could prove critical for missions envisaging lunar habitation and sustained human presence

Isro chairman S Somanath said: “You are right (the unclear emblem and logo imprints have given a new understanding). We already know it (soil) is different but we have to find out what’s making it different 

The lunar soil is not dusty but is lumpy. This means something is binding the soil, we need to study what is binding the soil,” he added.

The testing of the embossed images leaving an imprint was done on lunar soil simulant (LSS) created by Isro Satellite Integration and Test Establishment (Isite), where it left clear imprints.

ISSUES IN IMPLEMETING KAVACH SYSTEM ?

Image
There are frequent railway accidents in india due to  Mistakes in the signal system, lack of vigilance of loco pilots, and other technical problems are causing two trains to come on the same track and face accidents. The way the Kora Mandal Express met with a terrible accident near Bahanagabazar in Odisha in June... Recently, the incident of a goods train colliding with the Sealda Kanchanjanga Express in West Bengal has made the safety of the railway questionable. Such accidents can be curbed with the 'Kavach' system. 140 km per hour The efficiency tests conducted recently between Mathura-Palwal showed that this system can provide protection even to trains running at high speed. Shortage of funds Experiments have been going on for years to prevent trains from colliding. Among them 'Kavach' is modern. The system was designed by the Railway Standards Organization (RDSO) in association with three organizations after studying the models of different countries. T...

ON WHAT FACTORS STATES SHOULD MEASURE THE SUCCESS OF FREE BUS SCHEME FOR WOMEN ? HOW EVIDENCE BASED ADMINISTRATION WILL HELP TO MEASURE IT ?

Image
Delhi, Karnataka, Tamil Nadu, Punjab and recently, Telangana and Andhra pradesh have made it free for the women to travel in buses operated as part of Public Transport. As per the world bank report Women are the most significant, the largest number users of public transport in India, Women consider choosing the slower means of transport since it is affordable rather than choosing the fastest means of transport. This deters them from stepping out in the first place but the whole debate of Free bus scheme  for women divided between  as it is a freebie are vote Bank scheme but no one is talking about how can govt  effectively implement scheme ? are how can govt measure success of the scheme ?,so let's look into what a NGO in Tamil Nadu did to measure the success of free bus scheme ? and what other states should learn from It . How NGO In TN Measured The Success of Free Bus Scheme ?  Citizen consumer and civil action group surveyed about 3000 women's across 6...

Criticism on Civic volunteer system in Westbengal & How Politics-Civic volunteer nexus is working in west bengal ?

Image
Kolkata Police, following the shocking role of its civic volunteer Sanjay Roy in a doctor's rape and murder case, has directed all unit heads to ensure that all personnel, including civic volunteers, adhere to the force's rules and discipline. Abuse of power has become routine for such organisations.this crime is another example of how the force raised for community engagement is "turning rogue"  CM Mamata Banerjee Govt introduced it in 2018  has set a target of recruiting 1,30,000 civic volunteers, according to the chief minister’s office’s website. Till date 1,19,916 volunteers have been recruited. Qualification for recruitment  The minimum age and qualification to be a civil volunteer is 20 years and Class VIII pass respectively. They are posted in a nearby or same locality of which they are a resident. A volunteer gets an honorarium of around ₹15,000 per month. Officially, their recruitment is done through an interview conducted by an enrollment commit...
