Is a space elevator possible?

Is a space elevator possible?

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.

How much does it cost to build a space elevator?

A space elevator would be the single largest engineering project ever undertaken and could cost close to $10 billion to build.

Why is a space elevator 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.

How would a space elevator be built?

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.

How long would it take to ride a space elevator?

Travel on a space elevator would not be fast! The travel time from one end to the other would be several days to a month. To put the distance in perspective, if the climber moved at 300 km/hr (190 mph), it would take five days to reach geosynchronous orbit.

What is the purpose of a space elevator?

"The space elevator will reduce the cost of getting from Earth to space. It will also allow us to take very large payloads into space very easily, very safely. Because of that, we can build cities on the moon.

Is Japan making space elevator?

In 2012, the Obayashi Corporation announced that it could build a space elevator by 2050 using carbon nanotube technology. ... In 2018, researchers at Japan's Shizuoka University launched STARS-Me, two CubeSats connected by a tether, which a mini-elevator will travel on.

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 high is space?

100 kilometers

Do we age in space?

Spaceflight is an immersive experience that spares no traveler, while aging happens to every Earthling whether we like it or not. As such, life in space is a good model for understanding aging as a chronic process, Bailey says.

How noisy is space?

Although sound does not travel in the vacuum of space, the inside of the International Space Station (ISS) is quite noisy. There are many pumps and fans that allow people to live on the ISS. They control the station's heat, humidity, and carbon dioxide levels.

What's the loudest thing in the world?

The Krakatoa volcanic eruption: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB. It was so loud it was heard 3,000 miles (5,000 km) away.

Do planets make sounds in space?

On our planet, air molecules vibrate and transmit sound to our ears. In space, there are few if any molecules to deliver sound waves to the ears of people in space. ... They sound eerie and weird, but those whistlers and cracks and pops and hums are just some of the many "songs" of Earth.

Can you hear yourself in space?

In empty space, there is no air, and what we call "sound" is actually vibrations in the air. ... Light does not need air to travel, but then you don't hear it; you see it, or it is interpreted by your radio set and then translated into sound. Astronauts in space do talk to each other.

Is there wind in space?

In space there is no air, so no wind as per the common definition. However, there is something called solar wind. Solar winds are streams of particles emitted from stars, including our sun.

Could you hear an explosion in space?

Sound needs a medium to travel (such as air), but space generally doesn't have it. Therefore, sound can't really propagate in space. So you can't hear an explosion or any other sound in space.
