The fission sail is a type of spacecraft propulsion proposed by Robert Forward that uses fission fragments to propel a large solar sail-like craft. [1] It is similar in concept to the fission-fragment rocket in that the fission by-products are directly harnessed as working mass, and differs primarily in the way that the fragments are used for thrust.

Robert Lull Forward (August 15, 1932 – September 21, 2002) was an American physicist and science fiction writer. [2] His literary work was noted for its scientific credibility and use of ideas developed from his career as an aerospace engineer .
Founded in 1994 by Robert P. Hoyt and Robert L. Forward, Tethers Unlimited began developing products based on space tether technologies, including concepts for removal of space debris [4] and momentum exchange tethers for launching payloads into higher orbits.
The company Tethers Unlimited, Inc. (founded by Robert Forward and Robert P. Hoyt) [12] has called this approach "Tether Launch Assist". [13] It has also been referred to as a space bolas . [ 14 ] The company's goals have drifted to deorbit assist modules and marine tethers as in 2020 though.
"Starwisp" is a concept for an ultra-low-mass interstellar probe pushed by a microwave beam. It was proposed by scientist and author Robert L. Forward in 1985, [1] and further work was published by Geoffrey A. Landis in 2000. [2] The proposed device uses beam-powered propulsion in the form of a high-power microwave antenna pushing a sail.
In the 1970s, Robert Forward proposed two beam-powered propulsion schemes using either lasers or masers to push giant sails to a significant fraction of the speed of light. [36] In the science fiction novel Rocheworld, Forward described a light sail propelled by super lasers. As the starship neared its destination, the outer portion of the sail ...
Rocheworld (first published in serial form in 1982; first book publication, under the title The Flight of the Dragonfly, 1984) [1] is a science fiction novel by Robert Forward which depicts a realistic interstellar mission using a laser driven light sail propulsion system to send the spaceship and a crew of 20 on a one-way journey of 5.9 light-years (ca. 34 trillion miles; ca. 56 trillion km ...
