    In May 1946, the U.S. Air Force launched the Nuclear Energy for Propulsion of Aircraft (NEPA) project to explore the potential of nuclear energy for powering aircraft. [13] [14] This initiative led to a collaborative effort of the Air Force and the U.S. Atomic Energy Commission (AEC) known as the Aircraft Nuclear Propulsion (ANP) program, aimed at developing nuclear propulsion systems for ...

    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.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.

    The Zarya spacecraft was a secret Soviet project of the late 1980s aiming to design and build a large, crewed, vertical takeoff, vertical landing (VTVL) reusable space capsule, [77] a much larger replacement for the Soyuz (spacecraft). The project was shelved in 1989, shortly before the Soviet Union's collapse.

    The Chinese National Manned Space Program was given the designation of Project 921 in 1992. This broad project was divided into three phases: 921-1 to launch a crewed mission by 2002 in a craft that became the Shenzhou, the Project 921-2 temporary space station by 2010, and the 921-3 permanent space station by 2020. Care must be taken not to ...
