You make a fair point

Will a gun fired in the vacuum of space have a greater muzzle velocity than in atmosphere?
I imagine with no air in front of the projectile it would have less resistance while being accelerated down the barrel, but would this only have a negligible impact?

Because it's soviet union, notice the sepia filter and all the burnt out cars and shit. It's an integral part to not being American.

Great astronomers conference on how to colonize Mars, weak astronomers conference on how to police the language of the former.

Obviously you wouldn't use cyclers early stage, you'd use it once the destination is self-sustaining in the basics, do it right and the cycler can have its own ecosystem.
Cyclers will be able to move workforce there faster (as in quantity vs time) than any future starship will be able to. You double the number of passengers aboard on each ship because they won't have to sacrifice mass for amenities.

You are not going to truly colonize Mars with space bus or plain reproduction, regardless of the eugenic fantasy with automated factory that strive on 4chan.
Do the math, assuming 25 colonist per ship you'll need to refuel 400 ships to carry 10000c and 4000 for 100000c
Now imagine 10 cycler for 50 colonist you only need to refuel 200 ship to carry 10000c and 2000 for 100000c
Even if you needed 1000 launch to assemble the 10 cycler it will stay a win. Those cycler would likely be built in orbit then launched (it is easier to plan extra tank once than to assemble something good on the run).
And we are not talking propellant production there, it would take casual nuclear propulsion to even start to offset their long term advantage.

That's the problem with Musk fanboy, they can't think LARGE or long term. They only see the cheap fantasy with the Narrative that go with it, narrative where the enemy is anyone downplaying the space savior and his undefined fleet of unfinished interplanetary space bus.

Anyone got that webm of the Chinese controlled booster crash test? Thanks in advance.

Whatever the design, it must conform to whatever physical dimensions the active radiation shielding can encompass. Without that any organic life form aboard risks great and prolonged exposure. Apart from that I’d imagine an armored fuselage surrounded by a light truss network and some form of hybrid nuclear propulsion.

Not to mention all the unmanned projects that gather invaluable scientific data that will help us to prepare for future human exploration of the solar system.

this is really cool. Hopefully as space becomes more accessible there will be more companies like this. more companies in space will get us closer to a real space economy

If Martian society ever became successful and declared independence from earth would it win a war with it?

What would Martian society be like?

Would the severity of their environment cause them to push for eugenics and strict meritocracy?
