NASA awards UC Irvine $9 million to study underlying mechanisms of ?space brain? | School of Medicine | University of California, Irvine

The preliminary research by this scientist has already shown that 90% of the brain's memory functions would be destroyed, just during the trip to Mars. Only if some currently non-existing electronic or magnetic shielding system were developed, that would envelop a spacecraft, could a manned Mars voyage be possible. If it failed, for even a few moments---------------.
radiation shielding could be low tech. since we have to carry all the water we will need for a round trip to mars, you put the water in the outer sin of the ship, and that will shield the ships occupants from teh radiation.

It's a nice quote. I used to be pretty gung-ho for Mars habitation. I read the Mars Trilogy some years back. My thinking has evolved. I say we should design much more advanced robots than what we've sent so far. I say we should deploy a fleet of autonomous drones with high-def 360 3D cameras and LIDAR systems (so that humans safe on earth could have a virtual presence on Mars) along with high-functioning purpose-made AI research robots.

If the trip to Titan and Mars were roughly equidistant, I feel like we would only pay Mars about 20% the attention we'd lavish on Titan.

Same with Europa. I'd looove to see what's under the ice there.

What if all the information you've been fed over the years with regard to Mars is actually mistruths/falsehoods and disinformation?

Yup. Have you seen The Europa Report?

I have but it's been a few years. I remember thinking it was alright. Alien and Aliens are still by far my favorite hostile alien/creature feature flicks though.

We'll see if Musk flies on that first Mars mission, himself.

Interesting thread. The people you'd normally think are ignorant of the facts are actually making cogent arguments and the people who think they're scientifically literate, are not.

Mars is a dead, poisonous, ball of rock that gets constant solar radiation. It has almost no atmosphere and no magnetosphere. The soil is literally poisonous and could never be used by humans for horticulture. To survive on that planet would mean that the people going there would have to engineer a massive underground habitat just to avoid getting their dna bombarded with solar radiation (see no magnetosphere). Otherwise, a trip to Mars would be a cruel death sentence.

True, but I might leave my parent's basement some day.
