Space represents the greatest challenge the human race will ever face simply because of its sheer immensity. Even our own backyard, the solar system, has trillions of cubic kilometers of absolute emptiness whose scale is not easily envisioned by earth-bound explorers.
Reaching across these vast depths will require technologies that will challenge the limits of human innovation.
