If You Had A Tether From Earth To Geostationary Orbit And Cut It What Would Happen


Are orbital tethers possible?

Momentum exchange tethers can be used for orbital maneuvering, or as part of a planetary-surface-to-orbit / orbit-to-escape-velocity space transportation system. This is typically a non-conductive tether that accurately maintains a set distance between multiple space vehicles flying in formation.

Can you run a cable from space to Earth?

No Rope Can Support That Much Weight In fact, no rope could support 22,000 miles of its own weight. Not even a cable of the mightiest steel would work. In fact, there is no material you could use that wouldn't snap under its own weight long before it reached from earth to satellite.

What happens if a space elevator breaks?

Cut up to about 25,000 km If the break occurred at higher altitude, up to about 25,000 kilometres (16,000 mi), 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.

Is a space elevator even possible?

While progress has been made in several respects, the concept still hovers on the edge of possibility. For some scientists and engineers, the enduring challenges are enough to conclude that a Space Elevator will never be built (at least here on Earth).

Can you stay in orbit forever?

In higher orbits particularly out towards sort of 36 000 kilometres – what we'd call a geostationary orbit – in principle, they could stay up there forever. The orbit will tend to shift over time but it will stay orbiting the Earth in the same way that the Moon still orbits the Earth after millions of years.

Are there weapons in orbit?

Space-to-space weapons The Soviet Almaz secret military space station program was equipped with a fixed 23mm autocannon to prevent hostile interception or boarding by hostile forces. This was the first and so far the only weapon to be fired in space.

Can you touch a live Earth wire?

The live wire is the most dangerous one, since it is at 230 V. it should never touch the earth wire (unless the insulation is between them, of course!), because this would make a complete circuit from your mains supply to the ground (earth). A shock or fire would be highly likely.

Why can’t we build a space elevator?

Available materials are not strong and light enough to make an Earth space elevator practical. Some sources expect that future advances in carbon nanotubes (CNTs) could lead to a practical design. Other sources believe that CNTs will never be strong enough.

Why can’t elevators go into space?

Available materials are not strong and light enough to make an Earth space elevator practical. Some sources expect that future advances in carbon nanotubes (CNTs) could lead to a practical design. Other sources believe that CNTs will never be strong enough.

Is a moon elevator possible?

Lunar elevators can be made with materials available today. Carbon nanotubes aren't required to build the structure. This would make it possible to build the elevator much sooner, since available carbon nanotube materials in sufficient quantities are still years away. One material that has great potential is M5 fiber.

Is there a 220 mile elevator to space?

Do you age faster in orbit?

Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.

How many dead satellites are in space?

3,000 dead ones
While there are about 2,000 active satellites orbiting Earth at the moment, there are also 3,000 dead ones littering space. What's more, there are around 34,000 pieces of space junk bigger than 10 centimetres in size and millions of smaller pieces that could nonetheless prove disastrous if they hit something else.

Does US have secret space weapons?

One response to these trends was the creation of the US Space Force as an independent military service. But the US wants to do more to show that it shouldn't be messed with in space. Right now, the US only acknowledges one space weapon—a ground-based communications jammer to interfere with signals sent from satellites.

Will bullets fire in space?

Yes. Bullets carry their own oxidising agent in the explosive of the cartridge (which is sealed, anyway) so there's no need for atmospheric oxygen to ignite the propellant.

Why do birds not get electrocuted?

Birds sitting on a wire don't touch the ground (or anything in contact with the ground), so electricity stays in the power line. But, if a bird touches a power line and equipment or other metal that is grounded, it gives electricity a path to the ground, and the bird could be shocked.

Does earth wire carry voltage?

Earth wire is also having zero voltage similar to the neutral wire, but it accomplishes a very different role. It provides a grounded connection to all appliances and the equipment. Under the normal conditions, all current returns through the neutral wire and hence the grounding conductor will have no current.

Why is NASA not building reusable rockets?

NASA doesn't use enough rockets to make reusability worthwhile. Reusable rockets are only valuable if the frequency of launches is great enough to outweigh the cost of developing and utilizing the technology. It would have been silly to waste Apollo project funds trying to make the Saturn V reusable.

Is anyone building a skyhook?

While no skyhook has yet been built, there have been a number of flight experiments exploring various aspects of the space tether concept in general.

What would a space elevator look like from Earth?

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).

Would you feel gravity on a space elevator?

At 22,200 miles up, you would feel weightless, and then past that, you would feel a tug "upwards," towards the ceiling. You would settle your feet on what used to be the ceiling, and you could look "up" and see the Earth.
