How ISRO communicate with Mangalyaan ? Science Explained.......

The greatest rocket India propelled in 2013's Diwali was PSLV C25. The payload was MOM (Mars Orbiter Mission) or essentially refered as 'Mangalyaan'. The spacecraft successfully started  the Mars orbiting in September 2014. India turned into the principal Asian country to arrive at the Mars orbit, that too in its first attempt. China and Japan have failed toon Marsdo this so far.Mangalyaan's objective and study the red planet's surface features and mineralogy. It will look search for methane in the Martian environment that may give data about the past presence of life .

Why All Smartphones Are Made In China ?

The orbiter has been regularly sending pictures and information back home.

So how does this information move and communication thing works in space? Is it anything like the Internet associations we have at our home and workplaces? 


A quick answer is yes, but painfully slow.


All such strategic and data is taken care of by DSN (Deep Space Network). Huge antennas like the ones you may have found in the film Contact (1997) are utilized to transmit and get information. First such system authorized by JPL (under US armed force) goes back to 1958. 

America has three DSN offices at the deliberately picked areas - Canberra (Australia), Madrid (Spain), and Goldstone (US). When a strategic deep space, it is consistently taking into account in any event one of the office.

Russia, European Union, China, Japan, and India also have their own Deep Space Networks. So missions, for example, Mangalyaan are taken care off by the Indian DSN office at Byalalu town close to Bangalore. 

Since India doesn't have numerous system offices, NASA gives imperative position information by means of its three stations when required. 

In spite of communications being so significant in the space missions, the innovation in the DSN systems haven't been updated for a considerable length of time. With separation among probes and our planet extending in millions and billions of kilometers, the velocities are more woeful than the early dial-up associations. 

Blogger Vs Wordpress..... Which One Is Best ?

For example, during the Pluto crucial, Horizons' information was arriving at Earth at approx. 1200 bits for every second. Sending orders from Earth was even more slow at around 500 bits for every second. To place things in context, lets perceive what number of bits are required to make 1 MB. Indeed, the appropriate response is 8000000 bytes. 


In this way, next time you see a high goals picture of any heavenly body in our close planetary system, think about all the difficulty researchers experienced to get it going.

Indian DSN (IDSN) office is arranged at Byalalu town close to Bangalore. There are three reception apparatuses: 11 meter recieving wire, 18 meter antenna wire and 32 meter recieving wire. The 18 m recieving wire was for the most part worked for Chandrayaan mission.
