The future, then, looks bounded by that new outer limit of planet Earth, the geostationary orbit.

那，看要被限制在新外边界之内，即同步轨道。

Current designs estimate that it would take about 8 days to elevate an object into geostationary orbit.

依照现在设计，预估大约需要八天才能将一物体抛上同步轨道。

Objects at this specific distance are in geostationary orbit, meaning they revolve around Earth at the same rate the planet spins, thus appearing motionless in the sky.

处在这特定距离下物体，同时也处在同步轨道上，意味着它们绕行速率和自转相同，因此它们在天空中位置看起静止不动。

These mechanisms would require huge amounts of electricity, which could be provided by solar panels or potentially even nuclear systems. Current designs estimate that it would take about 8 days to elevate an object into geostationary orbit.

这些机制需要大量电力，这些电力可以由太阳能电池板甚至核系统提供。目前设计估计，将物体提升到静止轨道大约需要 8 天。
