Curiosity - The journey on Mars

    Curiosity made its step on mars for the first time. Enjoying its loneliness on mars but sharing its amusement with us by sending the pictures of the surface of mars. Its the most prestigious mission for NASA. The mars rover Curiosity is also known as the mars science laboratory was launched on Nov. 26, 2011 and was landed on mars on Aug. 6th , 2012. NASA started searching for life and habitat on mars with the eyes and wheels of the rover curiosity. Does the main purpose for this mission will be achieved or not ?
                     Anyway NASA`s curiosity on rover curiosity is undetermined.....

prithvi 2- tested again successfully

                                       

A single stage liquid fueled surface to surface missile capable of carrying a nuclear war head  was tested successfully on Saturday, from the Integrated test range near in Balasore in Odissa as a part of user trial by the army. A 9metre length and 1metre diametre carrying 500kg duplicate payload had hit the prefixed target in Bay of Bengal.  It was first test-fired on January 27, 1996 and the development stages were completed in 2004. This variant has been inducted in to the Army as well.though it is a ballistic missile , it do has the capacity to work as an Anti ballistic missile also.After a failed test on 24 September 2010 , two more missiles were launched on December 22, 2010 which proved to be complete success.  

Neil Armstrong - The legend

“That's one small step for man, one giant leap for mankind.” 

        

                                                     

The first man to step on the moon, lost his physical existence on earth. people considered him as one of the world`s best heroes for all time. On 25th august  2012, due to heart problem through which he was suffering from a long time has passed away.Neil Alden Armstrong was the first person to walk on the Moon, as well as an American astronaut, test pilot, aerospace engineer, university professor and United States Naval Aviator.

the story of columbia disaster

                                                      
     It was on 1st feb 2003, World was waiting fro them. Just 16min more to reach the surface of earth. But suddenly they lost receiving signals one by one. Its the blast that took 7 lives. One of the biggets disaster in the history of space exploration.There are people who witnessed it with their modern instruments.This disaster placed many questions in front of NASA and US administration.

                                                            

           They started digging for clues and reasons. Each and every scientist involved in the mission re caped the complete story since from launch to the blast. They have indulged about 20,000 people to collect each and every part of the debris of the plane for 3 months. Surprisingly they have collected the debris of 80% of the total weight of plane.they have also found an audio recorder in a forest which was undamaged ,but still no clues were extracted from that recorder. They examined the vedios and pictures of the launch. In that course they got to know that a small peck of foam parted from the booster and had hit the wing of the plane during the initial seconds after the launch.

                                                               

            Now they started a model simulation of the peck hitting the wing and the result shocked every one who were watching it. that small peck had made a hole of about 25cm diameter to the wing. This hole had not affected the plane during the journey in space. But while returning into the atmosphere , it started making difference. The speed of vehicle during the journey and during the reentry was about 28,000km/hr. And that speed resulted in the increase in temperature of the plane to about 1400 degrees Celsius. The external surface of the wing is thermal resistive but the damage was caused due to the hole occurred during the launch . The hot gases entered through the hole and started affecting the internal structure of the plane. slowly the heat sensors damaged one by one. The surface started melting , resulting the blast, 7 scientists lost their lives with in fraction of seconds. World witnessed the biggest ever disaster in the history of space race.

                                             

             family members of the astronauts  and the other people who were watching eagerly for the return , became stunned , they can`t believe what was going on at that time, but its the destiny and one should accept it.
