"We work to extend terrestrial networking into solar system space..."

Minor nitpick: it's the Solar System - i.e. capitalized (since it's a proper name). The Solar System is the planetary system that we reside in, the one that has the star Sol at its center.

> When not used as a proper noun and written without capitalization, "solar system" may refer to either the Solar System itself or any system reminiscent of the Solar System.[14]

They're solving for other solar systems too!
