An Earth-based space elevator would consist of a cable with one end attached to the surface near the equator and the other end in space beyond geostationary orbit (35,786 km altitude). With the tether deployed, climbers could repeatedly climb the tether to space by mechanical means, releasing their cargo to orbit..
Similarly one may ask, how much would it cost to build a space elevator?
A space elevator built according to the Edwards proposal is estimated to cost $6 billion.
Likewise, how would a space elevator work? A space elevator is a proposed transportation system connecting the Earth's surface to space. The elevator would allow vehicles to travel to orbit or space without the use of rockets. Gravity would pull downward on the cable, while centrifugal force from the orbiting counterweight would pull upward.
Moreover, would a space elevator slow the Earth rotation?
Each time you do that, you speed the Earth up, slightly. According to their calc, about 10^14 tons, 100,000,000,000,000 tons - or about a billion US aircraft carriers in mass launched on the space elevator would slow the Earth's spin down by 1 second. Earth's mass is 10^21 tons approx.
Would a space elevator have gravity?
The space elevator, as presently conceived, is a long “cable” stretching from the surface of the planet up into space. It does not escape gravity at any point along its length. If that were not true, each point would be accelerating away from its immediate point along the cable toward someplace lower or higher.
Related Question Answers
Is an elevator to the moon possible?
A space elevator could be anchored near a lunar pole, though not directly at it. A tramway could be used to bring the cable the rest of the way to the pole, with the Moon's low gravity allowing much taller support towers and wider spans between them than would be possible on Earth.Can we build a tower into space?
But most scientists agree that space starts somewhere between 80 and 100 kilometers (50 and 62 miles) above Earth's surface. Building a skinny tower that tall isn't possible. The cable was supposed to be 20 kilometers (12.5 miles), but it hit a snag when deploying and only 256 meters (840 feet) were released.What would happen if a space elevator broke?
If the break occurred at higher altitude, up to about 25,000 km, the lower portion of the elevator would descend to Earth and drape itself along the equator east of the anchor point, while the now unbalanced upper portion would rise to a higher orbit.Can we build an elevator to the moon?
A space elevator to the moon could be doable — and surprisingly cheap. New study suggests that a lunar space elevator could be built for about $1 billion using existing technology. Since the dawn of the space era more than six decades ago, there's been just one way to get to the moon and back: rockets.How far is space from Earth surface?
about 62 miles
How much would it cost to build an elevator to the moon?
Some estimate that an elevator could be constructed for as little as $6 billion. Compare this to the space shuttle program, which cost a total of $209 billion by one estimate.What is the space elevator made of?
A space elevator made of a carbon nanotubes composite ribbon anchored to an offshore sea platform would stretch to a small counterweight approximately 62,000 miles (100,000 km) into space.Could you climb a ladder to space?
Space yes, orbit no. You could, theoretically, climb a ladder for hundreds of miles, but as soon as you stepped off, you'd fall back down to earth. To stay in space - usually by being in orbit - you need massive lateral velocity, not merely altitude.Can you drop a rope from space?
In practice, no, not yet. There are two reasons: While the top end of the rope—at 36,000 km altitude—and the bottom end of the rope would both complete one revolution in 24 hours, the bit of the rope that is at, say, 400 km altitude wants to complete a revolution in 90 minutes.Can we move to Mars?
Mars One (2012-2019) The initial concept included an orbiter and small robotic lander in 2018, followed by a rover in 2020, and the base components in 2024. The first crew of four astronauts were to land on Mars in 2025. Then, every two years, a new crew of four would arrive.How would a space elevator be built?
There are two approaches to constructing a space elevator. One early plan involved lifting the entire mass of the elevator into geostationary orbit, and lowering one cable downwards towards the Earth's surface while simultaneously another cable is deployed upwards directly away from the Earth's surface.Which planets are tidally locked?
Pluto and Charon are tidally locked to each other. Charon is massive enough that the barycenter of Pluto's system lies outside of Pluto; thus Pluto and Charon are sometimes considered to be a binary system.How long does space elevator take?
In 2012, the Obayashi Corporation announced that in 38 years it could build a space elevator using carbon nanotube technology. At 200 kilometers per hour, the design's 30-passenger climber would be able to reach the GEO level after a 7.5 day trip.How high is space?
100 km
Why Space elevators are impossible?
Building a space elevator between the moon's surface and lunar orbit (to transport things such as visiting tourists or material mined on the moon) would be far easier, because of the weaker gravity and lack of atmosphere. Anyone hoping to take a space elevator into orbit from Earth, however, faces a long wait.Who is building the space elevator?
The idea for a space elevator was first dreamed up in 1895 by Konstantin Tsiolkovsky, a Russian scientist who did pioneering work in rocketry. As commonly conceived today, a space elevator would consist of motorized elevator pods that are powered up and down a ground-to-space tether.Is the moon stationary?
The moon orbits the Earth once every 27.322 days. It also takes approximately 27 days for the moon to rotate once on its axis. As a result, the moon does not seem to be spinning but appears to observers from Earth to be keeping almost perfectly still. Scientists call this synchronous rotation.How does a counterweight system work?
A counterweight is a weight that, by exerting an opposite force, provides balance and stability of a mechanical system. Its purpose is to make lifting the load more efficient, which saves energy and is less taxing on the lifting machine. The objects are then said to be in counterbalance.What is the time period of geostationary satellite?
23 hours and 56 minutes
