The rockets NASA has used have been great, but they can't take us far enough, fast enough to get us to places we haven't been before like Mars or beyond. A solution is to use plasma as propulsion and a project called VASIMR.
Since early times, people have looked into space and wondered about its mysteries. The vastness of space has opened our minds, but its size has limited our search. We want to explore distant worlds, but how can we travel faster so we can go farther into space?
The NASA Student Launch Initiative, or SLI, involves middle and high school students in designing, building and testing reusable rockets with associated scientific payloads.
