       It was launched in 19 April 1975 from Kapustin Yar, a Russia rocket launch and development bite un Astrakhan Oblast. The rocket used to launched this satellite is Kosmos 3M. 
      To launch this satellite india has agreement with the Soviet Union. India allow USSR to use  India Port for tracking ships and launch vessels.

    The Satellite had 26 sided polyhedron structure  with 1.4m (4.6ft) in diameter. All faces have solar cell except top and bottom.
   The Satellite is set to earth's orbit precisely at 96.46min orbit had an apogee of 611 km which equals 380 mi and perigee of 568 km which equals 363 mi and inclination of 50.6 degree.
Data receiving centre was in Bangalore. 
Real time data transmission rate is 256bit per sec. Its internal temperature limit ranged from 0 to 40 degree celsius.
A failure in the satellite's electrical power system halted experiments for four days. The spacecraft incurred a power fall which resulted in the ceasing of its functioning and transmission of information prior to its launch. Reason behind Failure of its power is still unknown.

   The cost of this project is about Rs 3 core. It returns to  earth atmosphere on February 11, 1992  after 17years of its mission life.
   This event was celebrated by Reserve Bank of India (RBI), image of the satellite was included on Rs 2 note in 1976 and 1997.


To commemorate the event both India And Russia released commemorative stamps.

India's First Satellite Launch Vehicle SLV 3.

Image
SATELLITE LAUNCHING VEHICLE 3 Image: SLV 3 SLV 3 is the 1st India's Experimental Satellite Launching Vehicle. Which was designed by ISRO. It was an all solid Four stage vehicle weighing 17 tons with the height of 22m. It can carry payload of 40Kg and can able to place it at Low Earth Orbit  (LEO). Image: SLV 3 It was successfully launched on 18th july 1980. However it was 1st  launched in  august 1979 but was partially succeed. It successfully placed the RS 1 satellite in its orbit . SLV-3 employed an open loop guidance (with stored pitch programme) to steer the vehicle in flight along a pre-determined trajectory. It was also launched in May1981 and April 1983. It was carrying the Rohini satellite which have Remote sensing sensors. After the launch of 1980, India became member of an exclusive club of space fairing nation.

Scientific analysis on the concept of Swarg (Heaven) and Narg(Hell) ?

According to all the religion in Our Planet Earth If a Person dies, His or Her soul went to either Heaven or Hell. What is Actually Heaven Or Hell? This question strikes every person ones in their life. Nobody Knows the truth behind this belief. Every Religion have its own Explanations. After having lots of research I have my own Explanations.

So, Here the question arises what is this 'LOK' mean??? If you Look on this word properly it is very clear that like Prithvi Lok is Actually Our Earth Planet here Prthivi is Earth and the word LOK is Planet. So Prthvi LOK means Earth Planet. Similar it is very clear that,  Swarg Lok is nothing but Swarg planet, Narg Lok is Narg Planet, Vishnu Lok is Vishnu Planet, Braham Lok is Bramas's Planet. These Are The Planet That is Situated somewh...

Bhaskara I : The 2nd Indian Satellite in Space. Image: Bhaskara I Bhaskara l was the Indian Mathematician and Astronomer born in Maharashtra in 7th Century (c.600 to c.680). He was first to use Hindi Number System and used circle as ziro. His name is used to named the India's 2nd Satellite Bhaskara I .  Image: Bhaskara I Satellite The Bhaskara was built by Indian Space Research Organisations (ISRO). It was launched on 7 june 1979 from Kapustin Yar , Russia. It was carried by Intercosmos launche vehicle into Earth's low orbit. Image: USSR stamp featuring Bhaskara I, Bhaskara II and Aryabhata   It is also India first low orbit observational satellite. It was placed in an orbital  Perigee  and  Apogee  of 394 km and 399 km at an inclination of 50.7°. The launch mass was 444 Kilograms. It was also an experimental satellite. The main purpose of this satellite was to collect data on hydrology, oceanography, telemetry. ...
