You don't necessarily need that actually. It would still be impossible due to Mars' thin atmosphere. Having wheels attached would still be an advantage.

That depends on whether or not Russia's plan to replace the current Soyuz models with the Soyuz-5 is successful or not. If it is, Korolev's designs/R7 derivatives will cease to fly once the Soyuz 2.1 has been phased out in favour of the Soyuz-5; which as you can see from this diagram, despite bearing the Soyuz name is basically an upgraded Zenit, as shown by it's lack of boosters and single RD-171 first-stage.

Wrong on a couple of points.

When WvB was put in charge of designing rockets for the US Army after the war, it was far from the US's most important project, and he nad his team languished for want of funds -- many of them left for private employment in aerospace.

When he was allowed to start working on launching a satellite, his team was made subordination to the Navy team, that repeatedly failed to get a Vanguard up.

WHenthe US manned program bagan, he was not in charge of the program, and orbital Mercury flights as well as Gemini flights did not use his boosters. He WAS in charge of the Saturn series of boosters used in Apollo -- and it is probably worth noting that Saturn series boosters never had a launch failure.

not an argument.

Sure, but we'll need much better ones before trying to land a big-ass ship with people on it.

What are the biggest objects we can resolve on our current imaging? About the size of a house? Something a lot smaller than that can fuck up your landing.

The lander in Apollo 11 was also supposed to be autopiloted. However, the pre-chosen spot was covered by big rocks. Armstrong then took control over the vehicle and landed it 500m manually, with 0,5m/s touchdown, which is waaaaaay softer than the softest automated landing (New Shepard).

Think about it for a second.

Lets suppose a large magnetic shield was deployed over the whole planet to stabilize the atmosphere from being blown the fuck out by the solar winds. This solves the greater problem of long term atmosphere issue. This isn't quite the problem at hand right now.

On the dome section, there is artificial atmosphere generated. However in order for the artificial atmosphere to stick stay, there needs to be enough pressure generated to keep the atmosphere down. If you look at the video, the clouds are basically only near the height of the dome, and not high above it in the greater atmosphere. This suggests that the atmosphere is kept in check by the walls. On the walls itself, there seems to be generation of atmosphere at constant rate(13 secs in). Then there's also these tall metal poles all across the walls. What is it for? My guess is some type of local electromagnetic field that generates a enough pressure around the dome to slow down the escaping atmosphere.

Active EM fields can increase air pressure with enough power, this can lock the atmosphere in a small(relative to the planet) area. So passive magnetic field for planetary scale + active magnetic field for local dome level.

There are no other useful greenhouse gases on Mars, so that's about it. If you wanted to increase the temperature to 0 degrees Celsius, you would need such a buttload of greenhouse gases, that Mars' gravity could never hold on to it, regardless of magnetosphere or not.

Atmosphere of mars can be separated into attraction to magnets, repelled by magnets or simply neutral.

CO2 makes up ~96% of the mars atmosphere. CO2 is repelled by magnetic field. So a strong enough magnetic field can increase the atmosphere in check. Since CO2 are the majority of martian atmosphere, the overall impact of a strong magnetic field would increase the atmospheric pressure.

This is similar but weaker case with Earth's atmosphere. We have nitrogen(78)/oxygen(21%), while nitrogen gets repelled by magnetic field, oxygen is attracted to it. This interaction is what causes lightning/thunderstorms.

All in all I highly doubt that with the payload capacities the BFS has, that you could transport more than a dozen or so people to Mars.

Look at it another way - they're taking their time perfecting the conceptual design, while at the same time developing critical technologies that would be necessary for the project (Raptor engine, large structural segments and tanks, etc..).
With each design iteration, they can check the concept against up-to-date data about their expected engine performance and structural capabilities, and delve into the design to check for other possible problems.
Since the Raptor is probably not ready anyway and they still haven't finished their Falcon 9/Heavy work, it's not too much of a loss to work this way.
If they had decided to work in a more traditional way, and start detailed design work on the first concept that looked decent, they might have run into some serious trouble with the engine performance or the structure, forcing them to scrap and rework parts of their design (and possibly actual fabricated parts).

And the BFR should be able to better the rule of thumb, because it's both large and integrated. Its pressurized volume is an order of magnitude bigger than the shuttle, and similarly sized to the ISS but integrated into one vehicle as opposed to modules, so it should be able to best either one.

This, the venture star parts where 90% complete when they cancelled the program.
And construction had already started on the launchbase
Also i recently found out that the failed tank story is seriously twisted around.
They had failures in the carbonfiber tanks, so the team made aluminium tanks next to the carbon fiber ones.
And turned out that the aluiminium tanks were just as good and a bit lighter then the carbon fibre ones.
But because of some bulshit reason congress would back out of the funding if the venture star did not take off without the carbon fiber tanks.
Then they pulled the plug out because of more bullshit reasons.
So here we have a almost finished very promising SSTO that has stopped death in its tracks, but then the us army comes to the rescue, but then they get cockblocked too by congress.
And even now, many years later after the carbonfiber tank problem has been fixed they still refuse to even talk about restarting the project.

The biggest expense for NASA isn't their hardware, but rather the SLS itself. The SLS itself is supposed to cost anywhere ~$50 billion dollar over the course of its lifetime/launch. While the project for the lunar gateway is only ~$2.7 billion.

Thankfully the first launch will only be in 2024, if BFR proves itself by then, NASA will be forced to cancel the SLS and say "FUCK YOU ULA/BOEING/etc."

Even if Falcon Heavy launchers had 50% failure rate, Falcon Heavy will still be cheaper for NASA and save NASA billions of dollars.

It wouldn't be necessary. The maiden flight demonstrated a long enough coast time to do a fast rendezvous with a previously-launched spacecraft. This would also increase the payload capacity for the Earth departure, since the departure stage can be launched with more propellant instead of a payload.

There's no plan to man-rate Falcon Heavy.

Anyway, Falcon Heavy's irrelevant for manned spaceflight. Important for satellites for 2 or 3 years. They might launch it a hundred times even. But BFR's just around the corner, and it's ideally suited for manned spaceflight. There's no point in wasting funds on any manned projects using something inferior. By the time you finish development of whatever you want to do, BFR will be ready for it to fly on. You don't have to try and squeeze things into tight spaces and tighter mass budgets. You can launch 8-meter, hundred-ton payloads to wherever you want them. You can launch crews of 20 with supplies for years.

At this stage, why even think about anything else?

This is not entirely correct. NASA's hardware is extremely expensive per ton to the point many claim launch costs are irrelevant and will not make a dent in the budgets even if launches were free and not mass constrained. Crazy, right? Met that argument great many times when arguing with people defending the cost and schedule of the JWST, among others. It boils down to "this is how it was done and how it should be done, its space science!".
This issue will become glaring when launch costs drop even more and comical situations might arise where mass optimized good-old-way made one of a kind buggy worth ten billion dollars is landed on the moon for a few million. Then moved to its location with cheap modified off the shelf commercial hardware acting as surface transport protecting the fragile buggy until its mission may begin.

And that number for the lop-g is plain false. Maybe those money will cover the paperwork currently being done on it.

Unless some big changes in the way contracting and budgeting works, NASA will be caught with its pants down in the era of cheap space travel.

Developing and building a certain payload takes several years. Now imagine being a researcher involved in the Curiosity program. You spent a decade of your life developing, building, and testing the rover. Then the day finally comes. It touches down on Mars. And it doesn't work, because of some little fuck-up or unexpected error. So all your work was for nothing. Also, economically speaking, it makes more sense to invest 3 billion in a probe that works, than 1 billion in one that doesn't.

But the psychological factor is more important. You need to be able to present successes. The russian stopped sending probes because they had a lot of failures due to non-optimal preperation. NASA is producing successes. That's the difference.

And yes, since the real money sucker is the probe development, launch costs are generally seen as not so relevant.

It's relative flyby velocity is 70km/s, we might be able to get a ship to intercept the comet either by starting out ahead of it or placing something into it's path, but said ship is going to need a huge amount of delta-v to safely match relative speeds with it to avoid getting slapped to powder in a collision. A ship with a magnetoplasmadynamic drive might have enough delta-V to match speeds and some spare monoprop or other higher thrust propulsion system to land, but a high thrust rocket will never have enough propellant to even moderately alter it's course, and an MPD would have to be enormous and extremely power hungry, and have a lot of stockpiled propellant to do the job, and it would take a long ass time for the change to happen.

Thermals are definitely a problem, but in most cases they're the most easily dealt with, especially if you're working with the energy efficient, high-power, low heat electronics found in modern consumer electronics.

A lot of the difficulties faced by those building spacebound electronics stem from their use of radiation-hardened variants some power guzzling toaster oven shit that was cutting edge over a decade ago – as an example, IIRC Curiosity was built around a rad-hardened variant of a 400Mhz PowerPC CPU. That's the same CPU used in fucking Gamecubes and circa 2000 fruit colored iMacs in a craft launched in 2011!

This approach isn't good at all for a number of reasons. You're better off with mass redundant modern tech combined with confidence voting systems – instead of an expensive single slow rad hardened computer that you can't afford to ever fail, use shitloads of tiny, cheap, (comparatively) fast totally separate ARM SoCs. The end result is the same if not more reliable and it costs far less.

SpaceX uses the latter approach for Dragon's electronics and will likely do the same for Starlink and BFR.

It's been a point of interest for me. What would it be like to live in different frequency ambient ELF fields?

Lifespan isn't really relevant. The brain is made of a number of delicate structures that are designed to be strictly one way processes, ie, they don't tolerate damage or repair well. Being pelted with nuclei traveling near c, cosmic rays, etc is a type of damage the brain has a poor ability to defend against, compared to other body systems.
