Although to date , we already use advanced technologies , high-powered telescopes , satellites and ballistic capsules , it would still be laborsaving for us to look back through time and see to it the beginnings of space exploration . We will do this by perusal two important events that en subjectd humanity to realize the possibility of subjugation spaceOn April 12 , 1961 , Moscow Time , the world entered the realm of outside space flying when the spacecraft Vostok 1 carried to outer space the start-off human being to ever orbit the domain . The name of the cosmonaut to first orbit the estate was Yuri Gagarin . Zal (2002 ) wrote an interesting record of the Vostok 1 flight as follows : The dart fomite blasted off nearly as scheduled at 09 :06 :59 .7 Moscow Time and the orbital insertion looked nominative to Gagarin . However unknown to the pilot , the core (second ) stage of the garden rocket burned longer than scheduled , leaving the spacecraft in a 327-kilometer apogee orbit , instead of planned 230 kilometers . It meant , that in case of a off failure of the braking engine , a natural reentry of the spacecraft caused by the friction in the upper aureole would take place at least quintuplet days after a 10-day supply of vital life support consumables onboard Vostok would run out .When the Russian government launched the Vostok 1 picture and chose Yuri Gagarin to be on board , there was no complete certainty that the mission would work out one c percent successful .

Two years earlier , the first artificial satellite to enter geocentric orbit , named Sputnik 1 , burned into space as it attempted to reenter the earth s atmosphere . Previous unmanned test launches of Vostok 1 prototypes turned out to be failures . Out of seven prototypes of the Vostok spacecraft flown (Versions 1K and 3KA , two spacecraft did non reach orbit due to the failure of the launch vehicle and two vehicles did not complete all their tasks (Zal , 2001A few hours earlier the flight of Vostok 1 , it encountered a strange difficulty . During the closure of Gagarin s capsule hatch , one of its sensing elements suddenly would not turn on . The hatch had to be re-opened to activate the sensor and everything went back to normal . Later however the spacecraft , was able to successfully get out of the earth s atmosphere . Its flight around the earth s orbit took a minutesThe plan regarding Gagarin s reentry into the earth was that he would detach from the spacecraft and enter the atmosphere by a capsule Strange as it may take care , the capsule took ten minutes longer than expected before it actually detached from the spacecraft . This is crucial because any misreckoning and digression from the...If you want to get a full essay, social club it on our website: Orderessay
