Where would a space elevator be built?

A space elevator on Earth or the moon could make space travel and cargo transport easier, cheaper, and more sustainable. Companies in China and Japan hope to build such elevators by , respectively. Japanese researchers have even tested miniature prototypes in space.

Does a space elevator have to be on the equator?

To support the weight of a tether and payload, the object to be used as a “space anchor” must actually be in an equatorial orbit but at a greater than geostationary altitude. The whole point of a space elevator is to get a payload out of Earth’s gravity well.

How would a space elevator be constructed?

There are two approaches to constructing a space elevator. Either the cable is manufactured in space or it is launched into space and gradually reinforced by additional cables, transported by climbers into space. Manufacturing the cable in space could be done in principle by using an asteroid or Near-Earth object.

Could a space elevator be built on the moon?

According to a study published in 2019, a lunar elevator could be the answer. A cable anchored to the lunar surface would stretch most of the 400,000km (250,000 miles) home. It couldn’t be directly attached to the Earth, due to the relative motions of the two objects, but it could terminate high in Earth orbit.

Would a space elevator work on the moon?

A very long cable

(The cable of a lunar space elevator couldn’t be anchored to Earth’s surface because the relative motions of the moon and our planet wouldn’t permit it.)

Is Japan making space elevator?

The Science Council of Japan is proposing a “hybrid space elevator” approach, which means simultaneously developing a concept that would be built from the ground and one to be constructed in space.

Can a space elevator be built?

A space elevator is possible with today’s technology, researchers say (we just need to dangle it off the moon) Space elevators would dramatically reduce the cost of reaching space but have never been technologically feasible.

Would there be gravity on a space elevator?

So if you were moving at a steady speed up the elevator, you would feel yourself get lighter rather rapidly. At 22,200 miles up, you would feel weightless, and then past that, you would feel a tug “upwards,” towards the ceiling.

Would a space elevator slow the Earth rotation?

Building the elevator will slow the earth by a negligible amount. Over time, launching spacecraft will slow it more but bringing back ore from the asteroid mines will speed it back up.

What happens if you cut a space elevator?

Cut near the anchor point

If the elevator is cut at its anchor point on Earth’s surface, the outward force exerted by the counterweight would cause the entire elevator to rise upward into a higher orbit, or escape Earth’s gravity altogether.

Why space elevator is not possible?

An Earth-based space elevator could not feasibly be simply a tall tower supported from below, due to the immense weight – instead it would consist of a cable with one end attached to the surface near the equator and the other end attached to a counterweight in space beyond geostationary orbit (35,786 km altitude).

What would a space elevator be 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.

How much would space elevator cost?

A space elevator built according to the Edwards proposal is estimated to cost $6 billion.

Whats at the bottom of space?

There’s nothing in the bottom of the space, or let’s say there isn’t any “bottom” of the space to begin with. When you’re in space, you aren’t supposed to address anything with the words ‘up’ & ‘down’, because it really gives the hard time for other people to refer it.

Why can we not see stars in space?

The stars aren’t visible because they are too faint. The astronauts in their white spacesuits appear quite bright, so they must use short shutter speeds and large f/stops to not overexpose the pictures. With those camera settings, though, the stars don’t show up.

Can you go in any direction in space?

There is an up and down in space. “Down” is simply the direction gravity is pulling you, and “up” is just the opposite direction. Since there is gravity everywhere in space, there is also an up and down everywhere in space.

Is there a ceiling in space?

It’s all relative. Inside the International Space Station, the ceiling might as well be the floor. The walls might as well be the ceilings. It’s enough to make your head spin.

Does space have a smell?

A succession of astronauts have described the smell as ‘… a rather pleasant metallic sensation … [like] … sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’.

What is underneath the planet Earth?

Deep in the centre of the planet is the ‘inner core‘, which we think is made of solid iron and nickel. This is surrounded by the ‘outer core’, which is also made of iron and nickel, but is molten. Convection currents in the outer core create Earth’s magnetic field.

Where does space end?

It extends about 20 miles (32 kilometers) above the Earth. Floating around the atmosphere is a mixture of molecules – tiny bits of air so small you take in billions of them every time you breathe.

Why is space black?

Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there’s virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black.

How cold is space?

Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).

Does time ever end?

“Time is unlikely to end in our lifetime, but there is a 50% chance that time will end within the next 3.7 billion years,” they say. That’s not so long! It means that the end of the time is likely to happen within the lifetime of the Earth and the Sun.

How will universe end?

The Big Freeze. Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. If the expanding universe could not combat the collective inward pull of gravity, it would die in a Big Crunch, like the Big Bang played in reverse.
