SpaceUp Ignite Talk - "Space Elevator / Tether: Concept

Umm no ,, lol

His research and cost findings seem pretty vague. They seem so certain with their findings though they haven't even built them yet. The part where the cables go up and cables go down when pulling a load up into space is very unrealistic - the traction lift method might not work as well in space because of the lack of gravity. To build the first one here on Earth, to "get out of gravity here" is very far-fetched. I am sorry, but I can't buy his story. Let's see if he can make it by 2019. ;)

ok i dont see this happening, so its an orbital platform traveling at over 17,500mph "orbit ish speed" and nasa wants to hang elevator cables into the atmosphere to lift cargo into space....

firstly how are you gonna get cargo on the 17,500mph elevator from the ground

then how are you gonna keep the platform in orbit while these cables are being slowed down by air resistance...

im proberbly getting the wrong idea haha, please explain and end my extreme confusion.

Such a cool idea. Hopefully it will come to pass. And if it does, it might me replicated on Mars giving us unprecedented access to the Mars surface.

[mrmaciejm]

Very realistic idea.
