The environment is much harsher. Even probes sent to Venus don't survive more than a few hours.

It is true that Venus is a lot closer to us than Mars.
However, Venus is also a lot closer to the Sun and
therefore has a surface temperature which is much
hotter than that of the Earth. In fact, the surface
temperature on Venus is 867 Degrees F.
The atmosphere on Venus is mainly Carbon Dioxide
with a steady rain of Sulphuric Acid droplets. Given
the very high surface temperature and presence of
extremely toxic acid rain, Venus would not be a nice
place to visit at all. No one would enjoy stepping out
into a hot acid shower.
Venus dies rotate on its axis, but ever so slowly. One
complete rotation ( a Venus Day) takes 243 Earth Days.
The Earth's orbit around the Sun takes roughly 365 1/4
Days. Venus' orbit around the Sun takes 224 Earth days.
So a Year on Venus = 224 Earth Days.
Oh, lest we skip that one, let me mention that the atmospheric pressure on Earth is about 14 PSI. On Venus
the atmospheric pressure is ninety times that or 1260 PSI.
So, beyond the acid rain and extreme heat on the surface
of Venus, the atmospheric pressure is also a killer and
humans would need an acid proof deep sea diving suit to
deal with the intense pressure and heat there. This is not a
place that is suitable for inhabitation.

We have sent probes to Venus as well as Mars and, as your previous answers have stated, the atmosphere is very much more aggressive than either the Earth or Mars, which makes it very difficult to explore.
Not only is there a lot of sulphuric acid in the atmosphere, but the atmospheric pressure is huge by comparison.

Yes Venus is closer but it also has an atmosphere of sulfuric acid and a surface temperature hot enough to melt lead (up to 900° C)
Also the Suns gravity is stronger as you get closer so you would need more fuel to get back.

Venus would also crush you because of the atmospheric pressure and simultaneously roast you in seconds. you could cook a pizza on Venus in 9 seconds.

venus is closer to the sun than mars and it's much too hot. if rocket ships are sent, the material might melt off or it might be too hot for the computer system to work and human will die, of course.

Venus is closer sometimes. Other times, Mars is closer.

Venus atmosphere is very thick and full of toxic gas (H2SO4 , CO, CO2 etc..) so it is very harsh to land some thing on her surface, let alone human beings. Russia has landed one prove and it was crushed flat just like a cockroach is trodden.

Probably because there is no prospect of life, past or present, on Venus. It is barren and very hot, and–I believe–temperatures in the past have been worse, not better, than they are now.
