That's the only thing we can do if we want to realistically colonize Mars for the extremely long term benefits. Almost nothing could be for sale because of the insane shipping cost so there would be no products but luckily there's enough people on this planet that have both the money to go ( Assuming absolute best case scenario with full reusability ) and the drive to endure the shittyness of it all just so in the far future, a self sustaining colony might be possible which would then advance to be a decent home away from home that would keep us going when an eventual extinction event happens. I personally think a handful of astronauts in a rotating underground base controlling robots on the surface would be a much more economical approach to building the infrastructure for a self sustaining city though.

>As the guy said, if you cross the line between perfectly fine and almost perfectly fine, your rocket blows up.

True, that is why it is difficult, if you get a 99.9% on the space exam, you fail.

This does not mean it's impossible.

By fine, I meant fine, not almost fine, not probably could of done it because most of it seemed to work, I meant fine, checked and good to go. Even if there was something wrong that needed to be refurbished which is definitely possible, that cheap refurbishment (HOLY FUCK FALCON 9 AND THE SPACE SHITTLE ARE NOT THE SAME THING) would still make it more than worth it to reuse which brings us back to the original point I disagree with ''reusability is a meme''.

Great points all around on why its super hard and why people probably shouldn't have tried in the first place because man that airplane comparison was spot on and wow he sure is right, it is difficult.

It is not a meme though, SpaceX has already trumped 90% of those difficulties and is on the verge of reusability with the last challenge (which I can't wait to be overcome because then we can all stop arguing over whether its possible or not) being just reusing a booster after checking that everything is good to go. (Good to go, not almost perfectly fine). Once you have quick, working reusabillity, the price will drop even more so which will open up more customers which will allow them to drop their price a little bit lower. In the future when we have true reusabillity like airliners, that will change the game in space flight.

Just to focus on your point and boil it down though.

>if you cross the line between perfectly fine and almost perfectly fine, your rocket blows up.

Absolutely true but I ask that you take into consideration that although it is difficult, reality is showing us that it is coming and things are looking good.

Final point / tl;dr

It is difficult but not impossible, things are looking bright based on reality and resuabillity is definitely not a meme.

Why is space exploration so gay now
Will we ever see a resurgence of super huge super expensive projects that capture the imagination of an entire planet
