Please change the height to feet
Or at least change Fahrenheit to Celsius. heh.

#162This is beautiful. I cried. And then I bought Mr Neal a coffee.
the space elevator.. it is a story of human progress .. it is something we will get to build one day
Re: Space Elevator
#163Amazing visualization. The most interesting part to me is the weird fluctuation in temperature. You'd think it would trend in a single direction. What causes all the frequent ups and downs?
At 17446m mark: > Unlike the troposphere, the temperature in the stratosphere increases the higher you go.
Right, but that's an 'effect', not a 'cause'.
Re: Space Elevator
#164Couple of things I learned from this: 1. Some birds go really high into the sky. Not sure how they evolved to tolerate such a hostile environment. But it seems that Duck-like birds are able to handle very high altitude. 2. There are lots of cool spaceships that man has made. But it seems most of these were made in the 1950-1990 era. It's a shame that we are no longer doing that.
Swans and geese may not look like the greatest flyers when they're on the ground, but they're among the highest flying birds. But why? Is it their size and strength? Why do people have trouble breathing at that altitude, but birds don't?

#165Wow, I really love these sites. Reminds me of years ago when things on the internet were more fun... sure a bit janky but people just went to town and built stuff they wanted.
Now everything is pretty mute and minimal (not saying its bad, I do this for my UX/UI too) so its nice to see this stuff!

List of cool spaceships being worked on now or recently: * The Falcon 9, the first partially reusable spaceship that actually costs less than not re-using anything * Terran R - a fully reusable space ship in the works by relativity space * RocketLab Electron - an active rocket that is unique in its use of electric turbo pumps, 3d printed engines, and advanced composites use * RocketLab Neutron - in the works, a large…

Re: Space Elevator
#167Absolutely beatiful. And using the metric system, how refreshingly un-American.
Re: Space Elevator
#168Sprites are AWESOME! They look so cool, does anyone know a good place apart from wikipedia to read about them?

Stoke Space is building a fully reusable rocket with a really unique second stage design.
Re: Space Elevator
#170Earlier quoted context omitted.
Space is big. 1) The cable's vibration resonance can be adjusted to avoid the bulk of larger objects, 2) new satellites can be mandated to have emergency maneuver systems (with larger objects not yet de-orbited cleared out by an elevator consortium), and 3) the cable will necessarily have close range defense systems probably at intervals for smaller objects that might be harder to detect at long range. The cable, als…
> In the long term, a space elevator is inevitable There are plenty of zero-fuel launch possibilities and a few very high-ISP ones. On the long term one of them is inevitable, but it's pushing it a bit to claim that it will be the space elevator.
Space elevator is by far the most efficient though . . right? Stuff that's on the end of the cable has enough angular velocity to get flung all across the inner system. Lunar orbit could be reached with release at 50,960 km. At the end of a 144,000 km cable you could get to Jupiter. I dunno what sort of other zero fuel launch techniques are getting considered though - there's no doubt a space elevator is just out of our capabilities today and for a while yet. Probably until our automation is good enough for self-directed asteroid factories to be a Thing.
