Space Travel and Tether Technology

What is a major difficulty with current space travel using rockets?

• It is incredibly slow.

• It cannot transport much cargo.

• It is dangerous and risky.

• All of the above.

What is the name of the concept that uses a long cable and a weight in space to help spacecraft gain speed and altitude?

• Space elevator

• Skyhook

• Orbital catapult

• Gravity sling

How does a rotating tether (Skyhook) help spacecraft gain speed?

• It uses powerful rockets to push the spacecraft.

• It slows down the spacecraft to save fuel.

• It acts like a catapult, transferring energy to speed up the spacecraft.

• It creates a vacuum to reduce drag.

What is a significant advantage of using tethers for space travel between Earth and Mars compared to traditional rockets?

• It makes trips longer.

• It requires more fuel.

• It significantly reduces travel time and rocket size.

• It is only useful for cargo, not people.
