TWO MILESTONES IN THE HISTORY OF SPACE EXPLORATIONTwo Milest stars In The muniment Of space Explorationby (insert name here (insert course identification dilate here (insert name of schoolTwo Milestones In The History Of Space ExplorationThe reconcile of distance conquest has been a very evoke locution of humanity history for the past a couple of(prenominal) decades . Although to date , we already use advanced technologies , high-powered telescopes , satellites and space vehicles , it would still be reformatory for us to look back through cartridge clip and attend the beginnings of space exploration . We will do this by canvass deuce important events that encap adaptedd humanity to realize the scuttle of hold in spaceOn April 12 , 1961 , Moscow Time , the globe entered the realm of satellite space shoot when the s pacecraft Vostok 1 carried to bulge outer space the premier human world to ever study the primer coat . The name of the astronaut to first orbit the human race was Yuri Gagarin . Zal (2002 ) wrote an interesting infix of the Vostok 1 safety valve as follows : The tack vehicle blasted off nearly as scheduled at 09 :06 :59 .7 Moscow Time and the orbital insertion looked nominative to Gagarin . in time unknown to the pilot , the core (second ) stage of the go up 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 arrant(a) failure of the braking engine , a native reentry of the spacecraft caused by the friction in the upper loose wind would take place at least v days after a 10-day supply of vital life support system consumables onboard Vostok would run out .When the Russian government constituteed the Vostok 1 chuck and chose Yuri Gagarin to be on board , there w as no complete certainty that the mission wo! uld work out one degree Celsius percent successful .

Two years prior , the first artificial satellite to enter geocentric orbit , named Sputnik 1 , burned into space as it attempted to reenter the reason s atmosphere . Previous unmanned test launches of Vostok 1 prototypes dark 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 non complete all their tasks (Zal , 2001A a few(prenominal) hours onward the flight of Vostok 1 , it encountered a strange encumbrance . D uring the closure of Gagarin s capsule hatch , one of its demodulators suddenly would not turn on . The hatch had to be re-opened to activate the detector and everything went back to normal . Later however the spacecraft , was able to successfully get out of the humanity 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 bet , the capsule took ten minutes longer than expected sooner it actually detached from the spacecraft . This is crucial because any misreckoning and digression from the...If you want to get a full essay, buy order it on our website: BestEssayCheap.com
