How our immune systems could stop humans reaching Mars

Are they talking about the "snowflake" immune system or "real working people" immune system?

[redhead]

Make sure everyone has plenty of soil-based organisms. They build the immune system from the gut. Best brand I’ve found so far is Garden of Life Primal Defense.

Humans are optimized for life on Earth. Expecting the organism to work property off Earth is foolish. The body was not made for space. It was made for Earth.

Colonizing other planets is immoral, because the people-to-be-born are forced to live in a hostile environment, and they were not given the choice.

Grandma always said, ‘You’ll eat a bushel for dirt before you die!’

So, they’d better start eating Mars dirt as soon as they get there. ;)

Puny humans!

Do not attempt to travel to Mars!

You will catch a cold!

Or we will blast you out of space!

Whichever comes first.

Space travel does not necessarily mean weightlessness. There is a simple way to create artificial gravity: spin the ship. If the ship is too small, connect two halves of it to a tether and spin that. Mars itself has about a third the gravity of Earth. The primary danger of living there is radiation.

[PapaBear3625]

It’s not so much “being in space”, but prolonged weightlessness. For long periods in space, we’re going to need to simulate gravity via centrifuges.

We will become a multi planet species. Don’t let the naysayers kid you.

[Calvin Locke]

Heck, you can achieve much the same by living in (on?) Antarctica.

IIRC, Mars has a lot of chromium in its dust. That should kill off a lot of nasty critters.

OTOH, pieces of probes sent to the Moon still had revivable Earth bacteria on them after spending a few years on the lunar surface, baked by the Sun during the waxing and waning, and frozen the rest of the time, bombarded by the solar wind, etc.

Or if we could create a sustained 1 g drive and shielding for protection, then the drive becomes the gravity- no rotation needed.

[Vaquero]

Once we can develop extremely powerful and efficient power supplies like fusion or the much romanticized antimatter, ships could maintain 1 G acceleration/deceleration to use the propulsion system to give you gravity.

[Paladin2]

Really?

Travel to the Moon is Deep Space?

Besides, a large space vehicle set spinning will create a sensory gravity (acceleration) at the periphery.

Why Bother? What’s Mars got that we don’t have?

[Vaquero]

Beat me to it

[bigbob]

Mars ain’t the kind of place to raise your kids, in fact it’s cold as hell.

[Vaquero]

It’s what mars doesn’t have. Antifa, Isis, Mecca.

Hi How does one measure the effectiveness of such a product?
