A mass driver is a proposed device that could launch payloads into space using a long tube lined with electromagnets (Figure 1). Some scientists argue that such a launch system would offer long-term cost savings over the use of chemical rockets. Scientists have proposed theoretical electromagnetic launcher designs as far back as the 1970s (O'Neill 1979). More recently, some have proposed the use of railguns originally developed for the U.S. Navy (McNab and McGlasson 2022). Other types of… Read more
