That's a neat question. Let's start by
thinking about what we need to survive anywhere:
We need to breathe, not be too hot or too cold, be
able to move around, and be able to come home
Venus has an atmosphere that is mostly carbon
dioxide. So you would need to bring oxygen in your
space ship to be able to breathe.
Carbon dioxide also happens to be a "green
house gas," meaning that it absorbs the sun's
warmth and heats up the atmosphere. Venus is
closer to the sun than the earth is, so it is very
hot and this carbon dioxide combined with Venusian
winds makes it hot even if you are on the shady
side of the planet.
So, how hot? It's about 450 degrees Celsius.
This is definitely much hotter than it naturally
gets in most parts of Earth's surface (except
maybe volcanoes), but humans create furnaces that
generate this much heat and even more, so we know
what kinds of materials could withstand these
But even if your space ship can stand the heat,
you still need to keep cool. You would need a very
large source of energy to power an air
conditioner. This is where some problems come in:
You could use solar power, but solar cells
don't operate well at high temperatures and don't
generate much power to begin with.
You could bring a fuel like gasoline to burn
and try to generate electricity to run your air
conditioner. But normally when we do this on
Earth, the heat from burning fuel is used to
evaporate water into steam, and the steam spins a
turbine (a wheel) to generate your electricity.
BUT, if you are on Venus, chances are that all of
your water has already evaporated in the heat.
But assume we engineer a system that can
provide enough energy for at least a short visit
to Venus, what other problems might we encounter?
The atmospheric pressure on Venus is very
high--almost 100 times more than on Earth. This
pressure has crushing power, and your space ship
would need to be made of materials that can stand
high heat while also being strong enough not to
The atmosphere is so thick that it would be
difficult for your space ship to move around, so
even if you don't move while you are on the
planet, taking off again would require very large
amounts of energy that again would need to be
In short, you would need many many things to be
able to survive on Venus. Organizing the
technologies to ensure a safe trip would take many
years of preparation and the safety would probably
still be uncertain, but I guess we'll see what the
Thanks for the question. It was fun to think
