No longer the domain of strictly nation-states, 'new space' is undergoing a wave of commercialization and growth. Two key engineering challenges, observed Louis Perna, are in-space communications and propulsion. He and his co-founder, Natalya Bailey, launched Accion Systems to provide cost-effective electrospray propulsion for satellites.
While the complexities of space travel are something that many members of society may recognize, less obvious may be the terrestrial challenges spacefaring tech developers face: designing and manufacturing hardware, cultivating an interdisciplinary team, and working through unit economics of complicated systems. Louis details his insider's view of the privatization of space, one electrospray ion thruster at a time.
