SpaceX and Mars

Every endeavor has it's dangers at start up, it's estimated over 30,000 died during the westward expansion, now we make the cross-country trip every day.

Musk has gone nowhere that NASA hasn't been already. He's being paid taxpayer dollars to replicate what's gone before.

Wow! Flight to Mars is real and it's happening. The best part was at the end when Elon explained his motivation for doing all this.

Here's a synopsis of his latest "state of the program" speech:

It would only require a highly localized magnetic field. We’re very capable of generating those.

I don't know that we are capable of generating a field to protect an entire planet from gammas. I'm not convinced that can be done locally, as in, a domed city on Mars. And domed cities are really the quickest way to populate Mars. Terraforming might take centuries.

We're not founding a Mars base any time soon unless it's a suicide mission. Hell, we don't even know if we can get people there without them all losing their shit during the long flight.

Re-supply would be out of the question. You couldn't even build a whole fleet of rockets and send them off at periodic intervals because Earth's orbit and Mars's have to line up at a certain point(s) for the flight to work. Otherwise, it would take far far longer.

We don't have the slightest clue how to terraform short of pumping a shitload of CO2 and other greenhouse gases out...but that's here on Earth, which has an atmosphere and a magnetosphere.

Oh right and Mars doesn't have a ****ing magnetosphere, which means it can't retain an atmosphere. We have no idea how to give a planet a magnetosphere, and it is impossible if current theorizing is right (that Mars lost its magnetosphere because its core cooled).




Any colony would have to be self-contained and almost certainly built from materials we brought. OR, the more likely scenario, we send autonomous robots that can also be directed from afar (but note: not for careful work given the message lag between Mars and Earth; about 3 to 22 minutes depending on where each planet is in its orbit. They'd have to be able to convert the iron and various stone dust that covers Mars into useable metal. Etc.

Mars and Venus do not have a magnetosphere and yet they both have an atmosphere. Not breathable but an atmo.

All the planets on the system plus some moons have an atmo.

I agree that any colony would need to be self-contained, however, your bold statement featuring curse words is not correct. Magnetosphere and atmosphere are not commonalities to planets.
 
I really hope Musk gets his wish to sod-off to Mars to become King of his own little fiefdom.
 
It is going to take launching over 5k Starships before they are going to get the launch correct. By then SpaxeX will have gone bankrupt. Musk will never make it to Mars.
 
The first private rocket to send astronauts into space was May 30, 2020. It took less than five years after that for Musk to threaten to decertify the rockets and strand the astronauts in space. If people ever got to Mars - which they won't - and somehow survived - which they won't - then they would end up as literal hostages to ever more expensive resupply missions.
 
So hows Musk planning on creating that magnetosphere?

Not on a ****in planetary scale lol…..

It’s a handful of people. You don’t need to do it on a planetary scale and we can and have generated stable localized magnetic fields exponentially more powerful than that of our own planet.
 
It is Musk talking BS since the problems associated with a long spaceflight to Mars and its effects on the human body have not been fully solved. NASA is actively researching these risks, which are grouped into five major categories: Space Radiation, Isolation and Confinement, Distance from Earth, Gravity fields, and Hostile/Closed Environments. These stressors can significantly impact human health, including radiation damage, muscle and bone loss, cardiovascular problems, and psychological effects.
 
We’d more likely create an electrosphere :p. (Reference in there)
