Why are cosmic rays a problem in a spacecraft flying to mars and not so much earth?

In order to protect our delicate human body from the destructive effects of
gamma rays, our tissues must be shielded from the gamma rays, by some kind
of material that absorbs them.
The Earth's atmosphere is a better gamma ray shield than a spacecraft is.
At least it's a better shield than any spacecraft that could be built without
a ridiculous weight, requiring a ridiculous and completely impractical amount
of fuel and money to propel it to anywhere.

Are cosmic rays dangerous to earths inhabitants?
Cosmic rays can be extremely dangerous, and exposure to them can cause genetic mutations, cancer, radiation posion, and death. Luckily, life on Earth is largely protected from these harmful effects by the Earth's atmosphere (which stops all cosmic rays with energies below 1 GeV) and the Earth's magnetic field (which deflects cosmic rays).
Can you stop cosmic ray shower?
No, you cannot stop a cosmic ray shower. You can block cosmic rays using various materials, but you cannot prevent them from entering Earth's atmosphere.
Is it true that cosmic ray will appear today?
Cosmic rays are continuously present in space - regardless of what day (or year) it is. Luckily, we are protected from cosmic rays on the surface of the Earth by the Earth's atmosphere and magnetic field. A small amount of comic rays can still reach the Earth's surface - particularly at higher altitudes.
Are cosmic and gamma forms ionizing radiation?
Yes indeed they are ionizing radiation. Of particular importance to astronauts who are exposed to much more than those who are Earth bound. But even flight crew on high flying aircraft have to pay attention to this.
How long does it take a spacecraft to get to mars from earth?
aproximately about 2 yreas
What are three ways people can see the earth from above?
You can see the earth from above in flying vehicles such as aircraft or spacecraft. We can also observe the earth remotely by using satellite imagery.
If a spacecraft travels from earth to the edge of the solar system what will happen to the gravitational pull between earth and the spacecraft?
The gravitational pull between earth and the spacecraft will become insignificant.
Can you fly while you are in a space shuttle in space?
You may have seen photos or videos of astronauts who appear to be floating through the air while in space. They aren't flying, nor are they really floating, they are falling. Any orbiting spacecraft (such as the space shuttle or international space station) is actually falling around the Earth in a circular pattern. They have achieved enough speed (over 17,000 mph) to continue moving around the Earth without the Earth's gravity pulling the spacecraft down. Astronauts aboard those spacecraft are moving inside the spacecraft and falling along with them at the same speed giving the appearance that they flying or floating inside.
What spacecraft landed on Neptune?
No spacecraft from Earth has ever landed on Neptune.
What are the release dates for Cosmic Collisions - 2009 Earth?
Cosmic Collisions - 2009 Earth was released on: USA: 21 June 2009
What spacecraft did John Glenn fly in to orbit the earth?
the Friendship 7 spacecraft
How does gravity affect the launch of spacecraft from earth?
It prevents the spacecraft from being launched as gravity causes it to be attracted towards earth.
Is it true that there is a spacecraft on its way to earth?
No.
What spacecraft studied earth?
a doctorinmay
What is Houstons nickname?
Texas Texans
The radius of the earth is about 6370 km A 7420 N spacecraft travels away from earth What is the weight of the spacecraft at a height 6370 km above Earth's surface?
10bls
What year did a spacecraft visited earth?
Every known spacecraft began on earth and went to other places. That's also true of every known drawing, component, fragment, subsystem, and model of spacecraft. Few of them ever returned to earth.
