Mars is dangerous.

Have you just now noticed that?

Red Planet: Don't go into orbit around Mars.
Mission to Mars: Don't go into orbit around Mars.
The Martian: Don't go into orbit around Mars.

What about the radiation exposure on the way to Mars?


Quote:But for missions further away from the Earth’s protective magnetic field, cosmic rays would be more of a problem. On its journey to Mars, the Curiosity rover provided crucial data on this and it was higher than expected. A round-trip manned mission to Mars would expose the astronauts to up to four times the advised career limits for astronauts of radiation due to galactic cosmic rays.

This was funny when Bill Maher did it

But it won't be so funny for people actually trying to do it.

Ice. Lining the hull. It's drinking water and shielding. Do try to keep up.

Not a fan of Musk at all, but I think everyone understood that a mission to another planet that doesn't have the same atmosphere or radiation protection as Earth's was going to be dangerous.

Water is relatively heavy.  Weight is always a problem on space flights.

Lead has the same problem.


The ISS is a marvel of recycling when it comes to water..... even if it means they are drinking piss.  But they still need supplemental resupply from earth.

Mars is dangerous? Who knew?

You may as well tell us that water's wet, Einstein.

What's amusing about the story is the invocation of Shackleton. 

Shackleton planned to go himself...... whereas Musk says, "you guys go.  And make sure you write."

Everything is 'Heavy'.

Something's 'Mass' is only important when you,

(1) Wish to get it into a stable orbit.

OR


(2) Wish to get it moving towards some where else.

(3) Addendum to (1) "How many boosters are you willing to strap on to acheive (1)?"

(4) Addendum to (2) "How much reaction mass do you want/need/can afford to attach to said 'Mass' to acheive (2)?"

With the proviso that "Once you're in orbit. You're ahlf way to anywhere/everywhere else."

Thumbs Up 

Not at work.

It seems to me that it would be a lot easier and more productive to colonize Death Valley, California or the Sahara Desert.  Consider
“I expect to pass this way but once; any good therefore that I can do, or any kindness that I can show to any fellow creature, let me do it now. Let me not defer or neglect it, for I shall not pass this way again.” (Etienne De Grellet)

Musk has always said going to Mars would be dangerous, and the likely hood of dying there would be high.

Here is an article from 2018 where he says as much.

That's child's play compared to the radiation you'll get once you get to Mars. Mars has neither a useful magnetosphere nor atmosphere so cosmic rays make it right down to ground level pretty much unfiltered. Ground level aurora borealis would be cool though. Briefly.

A seemingly reasonable idea from old science fiction. Water shielding works well enough for low energy radiation but cosmic rays come in at relativistic velocities. They spawn a variety of particles, such as tauons, pions, and muons, that more or less ignore mere mortal matter. For that you're going to need either a prohibitively massive shield or technologies we haven't discovered yet.

We have to have shielding. Ice is the lightest of the options. We have to have water anyway.

NASA is proposing. Tell them they're behind the curve and you're smarter than they are.

I don't doubt that NASA has proposed something of this type but for what and how feasible?

Moon first. Build or send manufactured devices there. Then from there to Mars when the Moon works OK. Baby steps...

Meanwhile, SN-15 completes its 10-km hop test at Boca Chica. Didn't explode on impact this time. Landed quite normally, but it did catch fire at the tail. Fire seems to be out.

SN-16, I assume, is next, but I'm not sure how many of these practice flights are to occur before their next big thing (I guess this is in practice for Mars activity? That seems so long off, though).
