Have you ever dreamed of visiting a distant planet or star? Even the closest stars are so far away that a visit might seem impossible-but maybe not! Learn how physicist Philip Lubin plans to create space probes that can sail on a beam of light to new and distant places faster 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.
