It traces how pilots, who first resisted the incursion of computers into their domain, gradually and grudgingly accepted the important role the computers played in… Read More Digital Apollo – Mindell (2008)
Currently, robotic spacecraft give us enormously more scientific and engineering value than manned missions. We should only invest in manned space flight once there is a clear rationale for a continuous manned presence in space. When Boeing figured out that bad time data caused Starliner to waste precious propellant during orbit insertion, making it infeasible… Read More We should not be wasting money on manned space missions.
