the futuremen

they will not come directly on the future, of course. they will try to aim just behind the future in its orbit. Then as they draw near and the future sweeps by, they will be turned by its gravity. This will make them fall toward the future in the direction it is traveling. This will lessen the difference between their speed and the speed of the future.

Extra fuel for braking will not then be required.
