Portal Space Systems develops maneuverable spacecraft for defense and exploration

Portal Space Systems’ founder says the company is developing highly maneuverable spacecraft for defense, describing them as “fighter jets for orbit,” while also aiming to support NASA and civil-space exploration. He argues that many spacecraft are too predictable and constrained by limited fuel in an increasingly competitive orbital environment.

The company has about 60 employees north of Seattle, according to its founder. Portal launched its first mission to orbit in March to test electronics hardware and has completed a roughly 600-pound Starburst spacecraft scheduled to launch on October 19 to demonstrate some of the company’s capabilities.

The founder expects more companies to build significant defense-related businesses as government agencies become more willing to partner with industry and acquisition reforms seek to deliver capabilities faster. He also expects some national-security space activity to remain undisclosed.
