I remember when Elon was first proposing this and even when the first tests began so many people doubted him and said it was impossible. These types of people are why we can’t have nice things.

Elon looking for way to make more profit.

When a rocket goes up, the stress and shaking is very violent. Im not sure what it is, but heard numbers around shaking of 80, 000 times per minute.
Imagine if the car or boat or airplane was shaken violently.

Every time I go to work I throw my car away.No wonder I cant get ahead.

In the movie Ankara they used elevators

Also the FUEL do really cost a lot, and can be used only once...but it weighed upto 80% of the total mass of overall "fully-loaded" and "fully -filled" Rocket...not only the metallic body/tank and the engine...i don't know how much the Solid-Booster cost, ..but the refilling/replenishing (plus all warrenteed inspection) maybe need upto 70% cost, and the reusable "shell" and "nozzle engine" is only 30% saved, estimatedly.(?!?)

What's that line...
Just because you can do something doesn't mean that you should

[rjvowels]

Humanity has more important shit to worry about...

Imagine this platform getting sued big-time

This is a misunderstood topic. I’m a huge fan of elon but there was a very good reason they didn’t try to do this. It requires more fuel to land. There’s something called the tyranny of the rocket equation, which means every kg of mass requires more fuel, and more fuel is more mass, which requires more fuel. Our rockets are already at the point in which 90% of the rocket weight is the fuel itself. Well when you aren’t using fuel to slow down something to land in the atmosphere, that’s a huge weight savings. This is why the space shuttle program used the “plane” design, because if you can use the atmosphere to slow down and land, then you don’t need extra fuel.

I just want to point out that the original engineers in space programs were no dummies. They did that stuff for a reason.

China is also working on the same concept.

[elfuturomio]

NASA never thought of that it's only had about 60 fuckin years to do so🤣

[doncahooti]

so he's going to fly the starship a thousand times ??

[gigafordrive]

it’s funny how one time-traveler trolling the whole world

[doncahooti]

get a bunch of dark energy and put it between the Earth and the spaceship.

[alexdetore]

But I think we really need is ways to transport cargo to space get it up there build a space station and then we can begin crafting vehicles in space that are only meant for space travel utilize the Sun for power or some type of energy source in space then we could begin to colonize the Galaxy or at least send out pocket fleets where many generations could live on

[zxetlfy]

Wouldn't it affect our ozone layer if we gained access alot of time?
How would we then deal with that

[Prismracing]

We also learn new technologies by always starting over. The shuttle exchanged innovation for repetition..
