“…Tsiolkovsky presented ideas about jet propulsion [1]. For further space exploration, more efficient launch methods are being developed (catapult systems, air launch, space elevator, space tower) [2] and methods of movement in space (orbital skyhook [3], solar sail [4], ion engine [5], laser engine [6], as well as non-reactive EM-Drive engines [7] and Mach effect thruster [8], hypothetical WARP-Drive engine [9], etc.). In Russia, some projects for the development of jet engines for Roscosmos were recognized by the Commission on Combating Pseudoscience RAS [10] as pseudoscientific.…”
