A Mars Mission's Greatest Challenge: Radiation
daSeiz writes "A New York Times article explores the possible effects of prolonged radiation exposure in deep space. Surprisingly, very little is known about the subject. We'll need to find innovative new ways of shielding spacecraft from fraction-of-lightspeed interstellar rubbish if we're ever to spend much time outside our own magnetosphere."
Tinfoil hats!
I am one of many. My idea is not unique, nor do I expect my voice alone to sway you. I speak in a chorus of opinion.
I've done the math. It would take shielding 100x stronger than the stuff I use to build the hats that keep the psychotronic weapons from affecting my brain!
Slashdotter are stupid and biased.
isnt every speed less than the speed of light a fraction of light speed?

Ready.gov has plenty of useful information on radiation shielding. If you have a thick shield between yourself and the radioactive materials more of the radiation will be absorbed by the thick shield, and you will be exposed to less. Perhaps NASA could use some insightful advice from the Dept of Homeland Securty. I bet a couple rolls of duct tape and some plastic would be quite useful in Space!

Well we will have to reroute main engine power through the deflector dish to create a graviton feedback wave which will in turn allow us to turn the radiation into a non-harful form of chocolate

The problem is finding a shielding material that will absorb the radiation that will affect a human body, without transmuting radiation that would pass harmlessly through a human into radiation harmful to a human. Thus, you need a shielding material that is cheap and has the same absorbsion parameters as a human.

I propose a solution to this problem. The main problem with launching rockets/satellites is exactly that -- launching them...i.e. generating enough power to achieve escape velocity required to overcome the Earth's gravitation force.
An alternate approach, however, would be to use the planet itself as a spaceshuttle for the reasons below:
1. Capable of high velocity:
The Earth is capable of travelling at very high speeds (currently 18.55 miles/sec) without causing noticeable discomfort/grievances to the passengers (astronauts).
2. Strong shield against radiation: The Earth's atmosphere provides a strong shield to protect the astronauts from high amounts of radiation present in outer space.
3. Fuel efficient: The planet is extremely power efficient at converting the energy generated due to the gravitational interaction between planetary bodies into rotational/revolutionary motion.
4. Huge storage area: The proposed space shuttle provides a huge hold/storage area capable of holding large amounts of food/water and other resources. The storage areas are regenerative, in that they help degrade waste into material which can be used to reproduce useful material.
The only area which needs research is navigation--figuring out how to make the Earth go where we want. I think that's what NASA/etc should focus on now.

Statistically, 25% will be able to invisible at will, 25% will be transformed into big stone monsters, 25% will be able to turn into flames without getting hurt, and 26% will be able to stretch their body many times its normal length.
There are 1% uncertainty on these numbers.
Q: Won't it get too hot?
A: We'll land at night.
Back on-topic - snag a big ice/rock comet and use its' water for shielding.
"In a new $34 million NASA laboratory here, part of Brookhaven National Laboratory, scientists are using subatomic particles accelerated to nearly the speed of light to slam into materials that could be used in a spaceship, and tissue samples and small animals. Using tools like PET and M.R.I. scans and DNA sequencing, they hope to shed light on ways that radiation damages biological tissue, and what can be done about it"
