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
balance
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

on february 5th 1974 nasa's mariner 10 mission took this first ever close-up photo of venus
made using an ultraviolet filter in its imaging system the photo has been color enhanced to bring
out venus's cloudy atmosphere as the human eye would see it but it wasn't until the following
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
the cause of the incident was an external gas tank explosion caused by a faulty o ring seal
engine's throttling up three inches now 104 challenger go at throttle
one up 15 seconds velocity 2900 feet per second altitude 9 nautical miles downrange distance
it was in 1990 that nasa launched the hubble space telescope
