what went wrong?

If you're talking about shit then boy do I have the spacecraft for you

>why didn't we go back to the moon
NASA and Congress wont admit it, fuck Rockwell, fuck Congress, NASA was a joke

What are some interesting recent developments in the world of space exploration/rocketry?

What made it a "white elephant" among launch vehicles?

It was supposed to drastically reduce the cost per pound of orbital payload delivery... but it did the exact fucking opposite.

It still has a higher energy density by mass. Pic related. It's the fucking space shuttle. You see that big orange tank? That's got fucking hydrogen in it. That shit's going into space. Can fucking batteries propel themselves into orbit? Didn't fucking think so.
>>weight of the high-pressure storage tanks
we can make better tanks and ways to store hydrogen. I do think this future is far off. And before you shit on hydrogen again get a load of this:

How's that for volumetric energy density? I will admit that this is fucking crazy. But who fucking knows where matsci will be in 50 years. Ok, so maybe lithium air batteries could theoretically do better than hydrogen, but the problem with air batteries is that they get heavier as you run them. The nice thing about hydrogen is that the end result is just water which you can easily exhaust. Hydrogen really is the future of energy though. You are forgetting that there's another way you can produce energy from hydrogen: fusion. Sure the reaction rate is fucking low in nature, but hydrogen is the most common element in the universe. Perhaps we can find a way to convert hydrogen from mass directly to energy? And I mean hydrogen not deuterium or tritium, because we can do that already.

fuck you faggot. I ain't watching all that shit just to argue with you. Give me some fucking text rather than a goddamn youtuber who's probably just making up stuff just to get views.

*kills your crew*

So was this thing a big piece of shit specifically, or are all space shuttle designs inherently inefficient, overly complicated, and dangerous?

A groundbreaking mission for spacex but hardly a groundbreaking mission for spaceflight.

Pic related flew to orbit and back 39 times already.
