INDIA IN SPACE ( PART-3 )

INDIAN ROCKETS AND SATELLITES:

                                                

                                                FOR THE FIRST TIME ON SEPTEMBER 20,1993 THIS KIND OF ROCKET WAS SENT BUT IN VAIN.DUE TO SOFTWARE PROBLEMS THE ROCKET HAS FALLEN IN TO THE SEA WITH IRSE SATELLITE.

                                                 BUT BY THE NEXT YEAR PSLV WAS SUCCESSFUL IN CARRYING A SATELLITE ( IRSP2 ) WEIGHING 870 KG WHICH ORBITED AROUND THE POLAR ORBIT.LATER ON PSLV WAS SUCCESSFUL STEP BY STEP.

                                                               

                                                  PSLV WAS PROVED TO BE RELIABLE. SOME FOREIGN COUNTRIES LAUNCHED THEIR OWN SATELLITES WITH THE HELP OF OUR PSLV.FOR EXAMPLE ON MAY 1999 INDIA'S OCEANSAT 1( 1036 KG ) SATELLITE  WAS SENT THROUGH PSLV TO A GREATER ALTITUDE.    

                                                   WITH OUR  INDIAN SATELLITE, TOOLSAT ( 45 KG ) OF GERMANY AND KITSAT ( 103 KG ) OF SOUTH KOREA WERE ALSO CARRIED BY OUR PSLV.THAT WAS THE FIRST TIME A ROCKET WHICH CARRIED THREE SATELLITES WAS LAUNCHED FROM SRIHARIKOTTA. 

                                                  LATER IN 2001, WHEN TES SATELLITE OF INDIA WAS LAUNCHED, ALONG WITH IT PROBA SATELLITE  OF GERMANY AND BIRD SATELLITE OF GERMANY  WERE ALSO ACCOMPANIED.EVEN IN 2007 JANUARY THREE SATELLITES WERE SENT THROUGH IN ONE ROCKET.

                                                   IN THE SAME YEAR ON APRIL AGILE SATELLITE OF ITALY WAS LAUNCHED FOR ASTRONOMICAL RESEARCH PURPOSES.

                                                   AT THE SAME TIME INDIA WAS TRYING TO MAKE ROCKETS   HAVING MORE CAPACITY THAN THE PSLV.IN THESE MULTI-STAGE ROCKETS OUR PURPOSE IS TO USE CRYOGENIC ENGINES.IN THESE TYPE OF ENGINES LIQUID HYDROGEN AND LIQUID OXYGEN WERE USED AS FUEL AS WELL AS OXIDISER. 

                                       WHEN INDIA WAS TRYING TO BUY THIS MODERN TECHNOLOGY ( CRYOGENIC ENGINES TECHNOLOGY ) FROM RUSSIA, AMERICA BLOCKED   RUSSIA NOT TO GIVE THIS TECHNOLOGY TO INDIA.BUT ATLAST RUSSIA AGREED TO SELL ONLY 7 CRYOGENIC ENGINES TO INDIA.
