I hint about the only person around it doesn't have TV coverage of the things
that man got the black up now you're gonna be getting a TV picture now
they'll yes we are getting a TV picture
one all
badly
this much we can say at this moment the planet venus is a very hot planet
the atmosphere is dense as primary constituent is carbon dioxide
there are many mr. you get remaining about the planet Venus these mysteries
will be solved by further analysis of our present data and hopefully by more
experience of this type in the future
nasa the national aeronautics and space administration presents Aeronautics and
Space report next month NASA plans to launch an unmanned Mariner spacecraft to
the planet Venus we know very little about Venus because we cannot see
through its thick clouds the 540 pound mariner will attempt to shed light on
the origin and nature of the planet and its environment giving us additional
knowledge about our solar system
ever since the first people were gazing up at the skies they had to have noticed
Venus it's so incredibly bright in the ancient records of the Mayans the Greeks
the Chinese people all over the world were seeing Venus up their naming it and
writing all sorts of stories about it but we could say that first modern
observations of Venus began with the use of the telescope in 1610 Galileo in the
early 1600 turned his telescope on to Venus and he looked at the phases of
Venus and that really refuted the geocentric model that was in play and
commonly accepted Galileo's observations were one of the first clear examples of
how observing another world could tell you about your own for the next 300
years
Venus continue to be an obvious target for telescopes these early observations
eventually revealed that Venus had a thick dense atmosphere this discovery
would define our image of the planet rather than seeing it as a meandering
brightstar Venus was now our mysterious sister planet
early in the 20th century or making huge advances in science and all kinds of
different fields with advances we start getting observations of Venus using
spectroscopy and using ultraviolet wavelengths the astronomers all the time
for making fairly reasonable assumptions that the atmosphere on Venus is very
similar to the one earth and that the clouds that they were observing war made
out of water vapor and subsequently they concluded that the condition atmosphere
was really wet and stormy and the service was swampy and a lot of
astronomers at the time even concluded that it was really good conditions for
why Venus
planet being so as we look back at the science fiction movies at the time we
see the Venusian surface portrayed with the big giant swamp monsters roaming
some of you may also have heard the story of a monster now confined here in
Rome do that beast is from Venus
there's never been anything like this before in fact or fiction first
spaceship on Venus
protect the final approach party call directly calculate
now
438 was october $YEAR 19 nasa's mariner spacecraft after traveling for months
and 217 million miles began fulfilling its mission as it rendezvous with the
planet Venus the soviet union also approached beat two spacecraft from two
nations although the machines were of different design their purpose was the
same by 1967 actually had two successful missions make it to Vince the first one
was the solvent venir for and nearly a month later it was followed up by the
masses there in five
the interesting thing about that that we were in the middle of the Cold War and
despite that the Soviet and American science is toward working together
cooperated share the data and the picture that the scientists god of Venus
was much more inhospitable than they really imagined before I 1967 if there
were any doubts about whether business was livable or not those doubts were
washed away it was not really conducive to sustaining life
now in an unexplored region of space
mariner was placed on its mercury intercept course by the gravity of Venus
the initial target on this first duel planet mission mariner 10 took more than
3,500 pictures during its rendezvous with Venus in February
for the first time after a decade of exploration mariner 10 was carrying
cameras we had ultraviolet cameras we could actually make some of the most
beautiful images here we have Venus the goddess of love and beauty and we had
yet to really make a close-up picture of her
yeah
Pioneer Venus was the last nasa mission to go to Venus to study specifically its
atmosphere in detail in the dynamics of that atmosphere that was 30 years ago
that we send it there it took a lot of detailed data that allowed us to test
theories that we had about why Venus was such a strange environment and one of
the most interesting of course is this idea of the runaway greenhouse effect as
an explanation for why is being is super hot
so while the Pioneer Venus orbiter was sending a steady stream of data back to
earth the solid program and it took several more chili eight missions back
to this and the highlight of this set of missions was the narrow 13 and 14 which
made it to the surface of Venice and while they will activate for 45 minutes
they took a handful of color panorama of the venetian surface now that they have
been reprocess they present a stunning view of the business surface and
forgetting the heat toxic atmosphere and the pressure it really looks tranquil
Venus the brightest star in the evening sky has captured our imaginations for
centuries
since august of $YEAR 1990 though a spacecraft named Magellan has Pierre
beneath this veil of mystery to show us the surface of Venus in unsurpassed
detail
Magellan was a pretty simple and elegant mission it had one basic purpose and
that was to get a detailed high resolution map of the surface topography
of the entire planet and what we saw was was an enormous surprise of very young
surface lots of volcanic features there were lava Plains and volcanoes and all
kinds of features it was an unexpected and marvelous revelation of what was
underneath those clouds at this point the american-soviet space missions are
really museum pieces and while everybody is now excited about the new data and
then you pictures images that we're getting from Mars
dennis is really staying in the shadow right now but throughout the history
business has provided us a lot of wonderful interesting theories announces
to the questions that we have here on earth and which shone the light on our
space in the universe but new players are coming into the game and with the
European Space Agency sending a spacecraft there in 2006 and the
japanese space agency planning 1 2010 the Venice exploration is going to pick
up and it really seems that very good opportunity to go back because there are
lots of things that we still don't know
and with nearly two decades passed from the last US mission to business isn't a
time we go back
about the only person around it doesn't have TV coverage of the things and that
man got the black up now you're gonna be the starting from getting a TV picture
now they'll yes we are getting a TV picture
chillin out
one all
great
