Web-Spinning Space Spiders

How would you get a large spacecraft into space without using a big, expensive rocket? How would you overcome gravity and protect the scientific equipment riding the rocket during the bumpy launch? Learn how physicist and engineer Robert Hoyt plans to create spiderlike machines that build large spacecraft weightlessly while in orbit around Earth. 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.
