安定的生活让人舒适安心，却也使人倍感空虚和失落。纵使在地球上定居了上万年，他们的目光依然投向宇宙的深处。直到某天，地球的科技终于可以支持我们实现太空漫游的梦想，于是我们的足迹便遍布太阳系的各个角落。未来世界，火星、土卫八、木卫二已经接纳了诸多地球移民，殖民地灯光闪烁，点缀夜空。人类加工小行星，在其内部挖出柱状空隙，以便创造适宜居住的环境。土卫六成为飞行遨游的绝佳场所，天卫五成为蹦极爱好者的乐园，土星成为观光客必到的所在。你我的梦，就在不远的未来……
本片许多场景都根据外太空探测器发回的真实的照片加工而成。

The film is about the immense distances between stars and the long durations we would have to endure in order to traverse them, even if utilizing methods of propulsion at the very limits of scientific knowledge. Ultimately, it comes down to our understanding of physics and the fundamental laws that govern the Universe.
If we ever want to travel to stellar destinations beyond our solar system, within the limits of a human lifetime - we will need to find ways to go incredibly fast.
