Ethan Siegel

With SpaceX’s recent ability to land a rocket, and with these guys wanting to engineer a system of high-velocity space propulsion, I think they might want to look into something like ideas proposed in The Millennial Project to merge these technologies, because putting lasers in space and maybe even using laser-based ablative propulsion as well as laser reflection could raise the possibilities to the next level in terms of speed and how much payload can be sent to nearby star systems.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
