Question

Why go to Mars and not Venus? What's so special about Mars?

Answer 1

Yeah, let's go to Venus where all the acid clouds are.. Good plan..

Answer 2

What's special about Mars is that it doesn't rain sulfuric acid there, and the surface temperature is not hot enough to melt lead, as on Venus. Probes that have been sent to Venus by the Russians lasted only an hour or so.

Answer 3

simple. mars can contain life, venus cannot. probes won't melt on mars, but they will on venus. mars' average temperature is about -150 degrees centigrade. venus is highly volcanic, and the hottest planet in the solar system with an average temperature of 250 degrees centigrde. there isn't much to be found on venus except lava and some volcanoes. mars is open for the possibilt of human colonization, as well as a checkpoint for the ongoing search for extraterrestrial life. no organic matter can survive on venus... its just too hot. there are only a few objects we can land on-

-the moon

-mars

-europa (jupiter's 4th largest moon)

-possibily callisto (jupiter's second largest moon)

-titan (saturn's largest moon)

-encaledeus (another one of saturn's moons)

-pluto, but we wouldn't want to land on there. its too cold for life, and it would take a while to get there.

we explore other celestrial bodies for a couple of reasons:

-to search for life

-for possible human colonization

-for scientific colonization

if a planet or celestrial body can't support life, or colonization, then there is no point to land on it. we landed on the moon do beat russia, but also for possible colinzation for military, and scientific endevors, as well as to search for life. we landed on mars primarily to search for life, and to confirm the possibility that we could colonize on there.

Answer 4

Mars has a thin atmosphere, maybe one percent of the Earths, is generally cold compared to Antarctica, and has no global magnetic field that could protect astronauts like the Earth's. However, in addition to that, the surface of Venus is hot enough to melt lead.  So, as bad as Mars is, it's not nearly as bad as Venus.

Mars certainly has water.  There is water ice at the poles.  It is reasonable to assume that there is water underground.  Liquid water does not stay on Mars.  It the low pressure atmosphere liquid water turns to steam rapidly.  But water trapped underground could be in liquid form.

On Earth, where there is liquid water, there is life.  So Mars is a good place to look for life.  Finding Martian life, even a microbe, even a dead microbe fossil,  would be very exciting. If it was determined to have chemistry significantly different from that found on Earth, it could lead to all sorts of new knowledge about how life might have formed on Earth.

Other places in the solar system that probably have liquid water: Ganymede and Europa (moons of Jupiter), Enceledus and Titan (moons of Saturn). Ceres.

Answer 5

because there can be life on mars and there may be thing s there

Answer 6

Because it's a downhill run to get back here.

Answer 7

bcuz there is zero probability of life, or anything remotely resembling life, on venus.

it's also very difficult to get space probes to last more than a few minutes on the surface.

Answer 8

Venus is actually closer than Mars, so you might think that it would be easier to go there. The distance to the planet, and the more frequent launch opportunities between the worlds are easier to deal with than between Earth and Mars, but unfortunately, Venus is an extremely hostile world - probably the most difficult rock in the entire solar system to land on for humans.

The atmosphere is so thick that the pressure at the surface is over 90 times sea level on Earth - it would be like being a mile underwater. The air is so thick that the space probes that land on Venus can drop off of their parachute several kilometers up in the air, and float down to the surface without them!

Not only that, the runaway greenhouse effect on Venus has rendered it the hottest planet in the solar system - the surface temperature is hot enough to melt lead. Worse still, the temperature is about the same for both day and night, and over the whole planet - the poles are just as hot as the equator!

Mars is a lot easier to survive - it's cold, so simply insulating against heat loss is all we have to do for temperature regulation, basically, and the air pressure is thin, so the space suits don't have to be so different than the ones we already know how to make. There also appears to be water on Mars, which would mean we wouldn't have to bring all of our water with us - a HUGE advantage over going to Venus.

Basically, of all the worlds out there, Mars is the easiest "next step" in our outward progress from the Earth. The Moon would be easier to colonize just because it's so close by, but Mars appears to have more of the resources we need to survive there than the Moon does.

We could probably build a colony on Triton, a frozen moon of Neptune before we could even set foot on Venus!

Answer 9

Way to hot, And the pressure of the atmosphere, would kill you, h**l it would crush a VW

Answer 10

Becuase Venus is way to hot! and we would proballt melt, sorry i don't no much so i can't give that much information!

Answer 11

Mars isn't showered by the sun's radiation as much.

Answer 12

Venus is completely uninhabitable to humans. The temperature is over 400°C, the pressure almost 100 atmospheres, the atmosphere is mainly CO2 and the clouds consist of sulfuric acid. You'd be boiled alive, crushed, suffocated and poisoned all at once.

Answer 13

for Americans i think it would be about global policing. there are alot of graves in the U.S.A. that represent our hope for peace. i think they fought so we didn't have to.
