following on from centuries of direct observation  physical space exploration commenced during world  

war ii with verna von braun's v2 military  rocket being the first man-made object to  

pass the 100 kilometer threshold the point at  which space was conventionally seen to begin  

it was this rocket that also provided the  very first pictures of earth from space  

taken at an altitude of 105 kilometers in 1949  the united states started to test the effects of  

space flight on mammals and albert the rhesus  monkey became the first vertebrate in space  

but sadly he perished during re-entry whilst  the u.s was experimenting with monkeys the  

soviet union was planning to send dogs  into space and two years later in 1951  

saigon and desicc became the first mammal  successfully recovered after space flight

but by far the most famous canine astronaut  of all time is undoubtedly like her who in  

1957 became the first animal in orbit a stray  mongrel from the streets of moscow her trip was  

inevitably going to be her last as no de-orbiting  technology existed yet but she paved the way for  

human space flight in the subsequent years  before now little was known about the effects  

of space flight on living organisms and prior  to leica many scientists believed it would be  

impossible for humans to survive the launch  as well as the effects of 0g environments  

this was also the year that the ussr launched  sputnik 1 the first ever artificial satellite  

the 58 centimeter polished sphere broadcast  radio pulses that could be picked up on  

earth by radio amateurs it orbited for  three weeks until its batteries died  

and it drifted silently before falling  back into the atmosphere two months later

today a new moon is in the sky a 23-inch  metal sphere placed in orbit by a russian  

rocket here an artist's conception  of how the feat was accomplished  

a three-stage rocket number one the booster  in the class of an intercontinental missile  

its weight estimated at 50 tons the smaller  second stage took over at 5 000 miles an hour  

and carried on to the highest point reached  500 miles up the artificial moon is boosted  

to a speed counterbalancing the pull of gravity  and released you are hearing the actual signals  

transmitted by the earth circling satellite  one of the great scientific feats of the age

sixty years ago this year in 1961 the  first ever human was launched into space  

the space capsule vostok one carried  soviet pilot and cosmonaut yuri gagarin  

for one full orbit of the planet  before returning him home safely

foreign

i believe that this nation should commit itself  to achieving the goal before this decade is out  

of landing a man on the moon and  returning him safely to the earth  

no single space project in this period will be  more impressive to mankind or more important  

for the long range exploration of space and none  will be so difficult or expensive to accomplish  

in 1963 engineer and cosmonaut valentina  tareshkova became the first woman in space  

she orbited the earth 48 times on the  vostok6 spent almost three days in space  

and she remains the only woman ever  to have been on a solo space mission

1966 luna 10 part of the year's soviet lunar  program was the first spacecraft to go into  

orbit around the moon and the first human-made  object to orbit anybody beyond the earth  

1968 was in the heart of the space race and it  was the turn of the usa to push the envelope of  

space exploration with their apollo missions  this was the year that apollo 8 launched

it was the first ever manned  craft to leave low earth orbit  

and after reaching the moon it also  became the first manned craft to reach  

another astronomical object which it orbited  before returning astronauts frank bormann  

james lovell and william anders safely back  to earth these astronauts were also the  

first humans to experience an earthrise  as photographed here by william anders

i'm gonna step off the lamb now

the following year brought the hotly  anticipated launch of apollo 11  

which was to perform arguably the most  iconic and greatest achievement mankind  

has ever fulfilled within the field of space  exploration to date to land on the moon

liftoff we have a liftoff 32 minutes  past the hour lift up on apollo 11.

tower cleared

in july 1969 neil armstrong became  the first person to walk on the moon  

where he stayed for more than 21 hours with  fellow astronaut buzz aldrin leaving command  

module pilot michael collins orbiting the  moon alone in preparation for their return  

from the planet earth first set  foot upon the moon july 1969 50.

in doing so collins became the first person  to orbit the far side of the moon alone  

and after the lunar surface mission  was complete the eagle luna module  

performed the first space  launch from a celestial body

very quiet ride there's that much crater  in 1971 the soviet union launched saliet 1  

the first ever space station paving the way for  permanent low earth orbit domiciles that are still

year that mankind would obtain its first  photograph from the surface of another planet  

the soviet union's venera 9 was able  to send back this panoramic photo  

and survive the 900 degree fahrenheit heat and  intense pressure of venus's surface for 53 minutes  

before it would succumb to the hellish  conditions of the planet's atmosphere

venus continued to be of interest to the soviet  union and in 1982 they sent another probe vanira  

13 to once again land on its surface as well as  a colour camera this probe was also equipped with  

microphones and was thus able to beam back the  first ever sounds recorded on another planet

two years later in 1984 nasa astronaut  bruce mccandless performed the first  

ever untethered space walk navigating via  the use of the specially designed manned  

maneuvering unit which he had helped to develop

tragedy struck in 1986 when nasa's space shuttle  challenger exploded shortly after liftoff  

killing all seven crew members including  high school teacher christa mcauliffe
