For one, without the stress of Earth’s gravity, her bones lose density. Studies show that astronauts, for instance, lose 1% to 2% of their bone density for every month spent in space, and that would be especially concerning for giving birth because the pelvis could fracture in the process.
Will we go to Mars?
Mars is hard Astronauts bound for Mars will have to travel about 140 million miles (225 million kilometers), depending on where the two planets are relative to each other. That means a trip that’s many months long, where astronauts will face two major health risks: radiation and microgravity.
Can potatoes grow on Mars?

Can humans live Venus?
Most astronomers feel that it would be impossible for life to exist on Venus. Today, Venus is a very hostile place. It is a very dry planet with no evidence of water, its surface temperature is hot enough to melt lead, and its atmosphere is so thick that the air pressure on its surface is over 90 times that on Earth.
Does it rain on Mars?
At present, Mars’ water appears to be trapped in its polar ice caps and possibly below the surface. Because of Mars’ very low atmospheric pressure, any water that tried to exist on the surface would quickly boil away. atmosphere as well as around mountain peaks. No precipitation falls however.
What is the current temperature on Mars?
Today, Mars has a high temperature of minus 14 degrees Fahrenheit and a low of minus 117. The weather data comes from the Mars rover Curiosity, which has been on the Red Planet for 458 sols.
