Welcome to my Wikipedia sandbox page !
Hai, I am Suman, a graduate student at University of Southern California and taking part in a course activity that involves editing wikipedia pages.

I'm a new wikipedian. Want to learn and contribute by editing some interesting topics in my field of interest; Aerospace Engineering :) . I'm currently editing "Mars Society" page.

Would highly appreciate your advice & support !

Best,

India
The Mars Society India chapter (MSI) was founded in January 2012 by Dhruv Joshi, an alumnus of the Indian Institute of Technology Bombay. Dhruv Joshi was inspired to set up the chapter in India after he attended a presentation by Mars society Switzerland chapter; during his visit to Switzerland . MSI was launched on March 2, 2012 at Mumbai, with collaboration from Nehru center (Planetarium) and students of Indian Institute of Technology - Bombay (IIT-B). MSI endeavors to set a platform for bringing immense talent pool of Indian students to the forefront and achieve country's ambitious space missions.

Bangladesh
Mars Society Bangladesh chapter was found in 2016. A group of 40 students and three teams from Bangladesh participated in 2016 University Rover Challenge (URC 2016) powered by Mars Society, held in June 2016 at Utah, USA.

Thermal Conductivity Analyzer
Thermal conduction property of any gas under standard conditions of pressure and temperature is a fixed quantity. This property of a known reference gas or known reference gas mixtures can, therefore, be used for certain sensory applications, such as the thermal conductivity analyzer.

The working of this instrument is by principle based on the Wheatstone Bridge containing four filaments whose resistances are matched. Whenever a certain gas is passed over such network of filaments, their resistance changes due to the altered thermal conductivity of the filaments and thereby changing the net voltage output from the Wheatstone Bridge. This voltage output will be correlated with the database to identify the gas sample.

Gas sensor
The principle of thermal conductivity of gases can also be used to measure the concentration of a gas in a binary mixture of gases.

Working: If same gas is present around the all the Wheatstone Bridge filaments, then the same temperature is maintained in all the filaments and hence same resistances are also maintained; resulting in a balanced Wheatstone bridge. However, If dissimilar gas sample (or gas mixture) is passed over one set of two filaments and the reference gas on the other set of two filaments, then the Wheatstone bridge becomes unbalanced. And the resulting net voltage output of the circuit will be correlated with the database to identify the constituents of the sample gas.

Using this technique many unknown gas samples can be identified by comparing their thermal conductivity with other reference gas of known thermal conductivity.The most commonly used reference gas is Nitrogen; as the thermal conductivity of most common gases (except Hydrogen and Helium) are similar to that of Nitrogen.

To Ian: New to Wikipedia: Need help in editing "Mars Society" page that has multiple issues !
Hai Ian, Myself Suman, a graduate student of Astronautical Engineering at the University of Southern California. I'm currently taking part in a course activity that involves editing wikipedia pages and I think you're my guide.

I'm actually a new wikipedian. I want to learn and contribute by editing some interesting topics in my field of interest; Aerospace Engineering :).

I'm currently editing "Mars Society" page. The mars society page has the following issues:

1) Relies too much on references to primary sources.

2) Needs verification with more citation.

Want your help to edit and add content with new references and citations; to make this page better! I would highly appreciate your advice & support !

Thanks
