But the vast distance also requires significant amounts of power to send a signal up to the spacecraft.

Large distances will require more resources due to the increase in competition, however resources are limited.

Strombrand's broad body shrank faster than distance should have required.

They said a greater distance would have required the span across the retractable roof to be longer and therefore cost significantly more.

The enormous distances even to the nearest stars would require an immense amount of fuel.

Novgorod's distance from the capital requires an overnight stay and train accommodations.

The distances involved in bird migration mean that they often cross political boundaries of countries and conservation measures require international cooperation.

The additional distances required an increase in motive power, especially as at that time, locomotives were changed after quite short journeys.

But greater distances required a big transmitter and those relays the newcomers had put on the moons.
