Solar-Wind-Riding Electric Sail

With today's technology, reaching the edge of the solar system takes decades, in part because rockets need fuel and heavy fuel slows down the rockets. Traveling without the weight of fuel would be faster, but what would the craft use to move forward? Learn how NASA engineer Bruce Wiegmann plans to use solar wind to move his craft faster and farther into outer space than ever before. The books in the Out of This World series feature projects that have won grants from the NASA Innovative Advanced Concepts program (NIAC). The program provides funding to teams working to develop bold new advances in space technology.
