One of the goals of this NASA mission is to expand the International Space Station (ISS) by adding two 17.5 tons trusses to it. To do so, the astronauts will rely on the Space Vision System (SVS) developed by the Neptec Design Group which will provide them with position and attitude cues during assembly. Despite his busy schedule, Iain Christie, Neptec's president, talked with me today about his company, his relationship with NASA, and about the future.
