111Asteroid deflection strategies — are methods by which near Earth objects could be diverted, preventing potentially catastrophic impact events. A sufficiently large impact would cause massive tsunamis and/or, by placing large quantities of dust into the stratosphere blocking… …
112space exploration — Investigation of the universe beyond Earth s atmosphere by means of manned and unmanned spacecraft. Study of the use of rockets for spaceflight began early in the 20th century. Germany s research on rocket propulsion in the 1930s led to… …
113Saturn V — Infobox rocket caption = The first Saturn V, AS 501, before the launch of Apollo 4 name = Saturn V function = Manned LEO and Lunar launch vehicle manufacturer = Boeing (S IC) North American (S II) Douglas (S IVB) country origin = United States… …
114Chinese space program — This article is about the Chinese space program in general. For the current Chinese space agency since 1993, see China National Space Administration. The launch of Tianlian, Xichang Center The space program of the People s Republic of China is… …
115Solar thermal rocket — Solar thermal propulsion is a form of spacecraft propulsion that makes use of solar power to directly heat reaction mass, and therefore does not require an electrical generator as most other forms of solar powered propulsion do. A solar thermal… …
116Liquid rocket propellants — The highest specific impulse chemical rockets use liquid propellants. This type of propellent has a long history going back to the first rockets and is still in use in for example the Space Shuttle and Ariane 5. History Early developmentOn March… …
117Woodward effect — The Woodward Effect, also called the Mach Effect (particularly by Dr. Woodward himself), is an experimental method for propellantless propulsion. It was first proposed by Dr. James F. Woodward, a physicist at California State University at… …
118EmDrive — (also Relativity Drive) is the name of a spacecraft propulsion system proposed, and reportedly developed, by Roger Shawyer.cite news|title=Relativity drive: The end of wings and wheels?|date=2006 09 08|author=Justin Mullins|issue=2568|work=New… …
119Single-stage-to-orbit — The VentureStar was a proposed SSTO spaceplane. A single stage to orbit (or SSTO) vehicle reaches orbit from the surface of a body without jettisoning hardware, expending only propellants and fluids. The term usually, but not exclusively, refers… …
120Hall effect thruster — In spacecraft propulsion, a Hall thruster is a type of ion thruster in which the propellant is accelerated by an electric field. Hall thrusters trap electrons in a magnetic field and then use the electrons to ionize propellant, efficiently… …
