Space Elevator Timeline (now obsolete by Starship) - Viva La Vida (Coldplay)
Показать описание
Please type in the comments: Do you think this concept would have ever been made if SpaceX never existed? Do you think a space elevator will be built anyway, despite SpaceX's competitive prices?
The problem with space is that it's expensive. But the price is coming down really fast.
(1981-2011) NASA's Space Shuttle: $58,181/kg
(2010-_____) SpaceX's Falcon 9: $2,939/kg
(2019-_____) SpaceX's Starship: $20-$50/kg
If successful, either a space elevator or Starship would initiate a shattering revolution in the colonization of the Moon and Mars.
Before SpaceX, the only way thought to bring down prices that much was a concept considered to be radical: the space elevator. Even if SpaceX did not develop Starship, the construction of a real space elevator in the 21st or early 22nd century would have been unlikely due to the challenges in material science mass production, the logistics of space debris, logistics of powering the climber, and the logistics of safety procedures if the tether were to break. Enjoy the video anyway, it draws out a potential timeline if it became the dominant space transportation system.
Food for thought:
If it breaks, (let's say somewhere in the middle), the lower segment will fall to Earth, near harmlessly as a very thin cable. The upper segment will fall "upwards" into a higher orbit around Earth. Any passengers must burn to accelerate depending on their altitude, to either avoid fatal reentry, or fatal impact.
Multiple cables would eventually become a growing hazard with spacecrafts' trajectories. Space debris colliding with this cable (possibly Carbon Nanotube or Graphene) has not been tested.
