Yeah, ofcourse its bullshit.
But spaceX has a close relationship with nasa, and nasa has multiple versions&working prototypes of about everything you need to keep a crew alive in space for a long time.
And if the BFR actually works, then the only part of spaceX in the mars mission will be spaceX building the booster and the outside hull of the ship.

If most cosmic rays and solar wind are blocked by earth's magnetosphere, why wouldn't placing electromagnets around the crew section and power them to a few micro-Teslas be sufficient for most radiation dangers?

They aren't, they're blocked by the atmosphere. That's why airline pilots get significant levels of radiation dosage, since they spend many many hours above a large fraction of the mass of the atmosphere.

First of all, Musk talks big but in the end, the only reason half his businesses are a success is because he’s such a huge meme amongst the common populace. Vertical take off and landing vehicles have been around for years and spacex WAS NOT, the first to do it. The only reason the business is also booming is because they receive government subsidies. The Hyperloop idea has been around for around a hundred years and even then musk has barely done anyhing with his dumb fucking company, other than bore a small tunnel. The guy is a captain of industry, NOT a scientific or engineering genius.

>One big feature they totally forgot for going to mars is radiation shielding.

Radiation shielding for a Mars mission will consist of a solar storm shelter located most likely in the center of the ship, surrounded by supplies. You need like 1 ton per square meter of mass to shield against even the largest solar flares.

As for cosmic rays, there will likely be no shielding against them because you need many tons per square meter and it is just too much mass. The solution will be a fast trajectory (3-5 months), which is enough to keep cancer rate increase at manageable several %.

Radiation will not stop a Mars mission.

>spacex WAS NOT, the first to do it

VTVL toy rockets existed since the 60s, but nobody cares about that triviality. SpaceX was the first to do it for an orbital class booster lifting an actual payload, and the first to do it in an economical manner. They deserve all the credit they get for it.

>> No.9992824

Fuck no. Earth's magnetic field can block cosmic rays due to extreme distances. It's micro teslas over thousands of kilometers which is enough to deflect charged particles. For smaller things we need stronger magnetic fields. Artificial magnetospheres may be possible though. Most of the constraints come from keeping superconductors cool.

>> No.9992829

It cannot even do that, vast majority of cosmic rays are blocked by our atmosphere. Magnetosphere only redirects some low energy cosmic rays and solar protons.

Water actually works well for shielding. Since you're gonna need a lot of it to keep your crew alive it would be best keep it stored in the outer walls.

It would be best to keep the parts where humans spend the most time near the inner part of the ship and storage + places where people need to be the least near the outer walls.

You mean the Shuttle? It was designed by Rockwell (now Boeing) who also made the Apollo service module. The LEM was made by Grumman, Rocketdyne made the F-1 engines for the Saturn V, and many other PRIVATE companies designed different parts for NASA's ships. The astronauts aboard apollo pissed into bags using a device created by a condom manufacturer. Having more companies is a good thing you brainlet.
