A rocket must carry the fuel it expels in order to accelerate its structure and payload. The rocket equation relates the change in speed to the fuel mass expelled. To launch a spacecraft into Earth orbit requires a multi-stage rocket, since otherwise the mass of fuel required would be prohibitive. While the details vary among historical and…

Involving students in state-of-the-art research from an early age eliminates the idea that science is only for the scientists and empowers young people to explore STEM (Science, Technology, Engineering and Maths) subjects. It is also a great opportunity to dispel harmful stereotypes about who is suitable for STEM careers, while leaving students…

Develops a simple model of radio wave propagation and illustrates how basic physical concepts such as refractive index, refraction, reflection and dispersion can be applied to a situation normally not met in introductory physics courses. (Author/GA)

Proposes the production of science fact films of life in a space station in order to increase student interest while teaching fundamental physics concepts. (SL)

Discusses the atmospheric characteristics of the earth and their implications for the development of life on earth-like planets. Indicates that the chance of life developing on other planets is not as great as men might have thought. (CC)

Various aspects of the solar sail spacecraft such as solar sailing, solar sail design, navigation with solar sails, solar sail mission applications and future prospects for solar sailing are described. Several possible student projects are suggested. (KR)

Proposes practical problems involving the dynamics of rocket and orbital problems for the secondary level physics class. (SL)

Summarizes the scientific activities of the Apollo program, including findings from analyses of the returned lunar sample. Descriptions are made concerning the possible origin of the moon and the formation of the lunar surface. (CC)

Presents a brief explanation of the solar system, including planets, asteroids, satellites, comets, planetary orbits, as well as, old and recent cosmogonic theories. Indicates that man is nearer a solution to the origin of the planetary system than ever before.
