trope in many works of science fiction although the solar sail is more popular: The ancestor of the magsail, the Bussard magnetic scoop, first appeared in science-fiction in Poul Anderson's 1967 short story To Outlive Eternity, which was followed by the novel Tau Zero in 1970. The magsail appears as a crucial plot device in The Children's Hour, a Man-Kzin Wars novel by Jerry Pournelle and S.M. Stirling (1991). It also features prominently in the science-fiction novels of Michael Flynn, particularly in The Wreck of the River of Stars (2003); this book is the tale of the last flight of a magnetic sail ship when fusion rockets based on the Farnsworth-Hirsch Fusor have become the preferred technology. GURPS Spaceships features both solar sails and magnetic sails as possible methods of spacecraft propulsion. Although not referred to as a "magnetic sail", the concept was used in the novel Encounter with Tiber by Buzz Aldrin and John Barnes as a braking mechanism to decelerate starships from relativistic speed. See also interacts with magnetosphere in similar manner to magsail (Magnetized beamed plasma propulsion)a beam-powered variant of mini-magnetospheric plasma propulsion (M2P2). Other methods of spacecraft propulsion used to change the velocity of spacecraft and artificial satellites.
