Yes, the steps are landing. What's unusual about this? Is it necessary? Is it safe? Do you think that all space companies would not be able to make such a landing and then some unique discovery? A man who just threw batteries from a store into a car?  :)
It's a good show, I think. I'm not saying that it's bad, on the contrary - it's better than many other things. But I don't see any admiration.
Maybe I'm wrong, don't worry - just my opinion.  :-//

Do you realize that they reused Falcon 9 boosters around 50 times? Instead of building a brand new booster each time. The most used booster launched/landed 7 times already.

Nobody ever done it. And almost everybody joked about them and told it's impossible  till the end of 2015 when they finally succeeded. Включая вашего Дмитрия Батутовича. Now Rogozin boasts they will make their own rocket which lands. Флаг ему в руки и удачи.

If it's so easy to land 15 story building falling down from space, why nobody else did this?

I get it now, I guess we're all "mis-understood"  ::) what S. Petrukhin intents to say, that Rusia is so rich, that throwing away such big rocket stage (pic below) is no big deal, probably for Rusia its like wiping nose with tissue paper and throw it away.

Right ?  :P

You'll probably be surprised. But this big rocket is cheaper than the small Falcon, as far as I know. In addition, the wreckage is collected and recycling.

By the way, the heavy Angara is being prepared for launch, already on the launch pad.

However, you can't hear me... Everyone can plant steps, but for some obviously good reason, they don't. It is possible that the reason is actually not so weighty and will continue to develop in this direction. My opinion: the Shuttle was a much-much bigger breakthrough. It would be more reasonable to make a new rocket based on its principle. This is my opinion, I'm not a rocket science professional.

You know, in Russia, thinking people are puzzled by Rogozin. During the Soviet Union, I was on a tour and met with cosmonaut Leonov. We all smelled the glove - it had the smell of space.  :)  And even then, it was talking about cooperation in space. I listened a lot of cosmonauts stories - no one is hostile to the Americans. Moreover, the Americans have largely saved our cosmonautics and are grateful to them for this. There was competition, and there was a military side, of course. But this is not the case now. And the mentioned Rogozin... I have friends who work in the Roscosmos - all of them dissatisfied with current management. Everyone says that people of Soviet training will leave and it will be very bad. Perhaps, for the Russian cosmonautics, modern leadership is a disaster.

Scrap is worth nothing compared to what it once was. Buy a 1000$ GPU, smash it and sell it for scrap, you won't get even 1 dollar back.
Imagine with every trip you scrapped your car and bought a new one, instead of doing basic maintenance and using it again.

SpaceX made reusable engines and this serves more than to just lower the cost but additionally boosts development because the engines can be examined after landanding and even more data can be collected.

Maybe you can explain why others didn't? Don't you think you were smart enough? What reasons do you think prevented from landing earlier?
I can assume that there is a question of money: make a new car for each trip, as you put it, much more profitable for interested people.
But there were no people in the USSR who profited from space.

Or, nevertheless, space is not a supermarket and it is more reliable and even cheaper to go there in a disposable car, oddly enough?

I don't know the answer. But I'm sure any space agency could do it.
