The International Solar-Terrestrial Physics Science Initiative (ISTP), a collaborative effort by NASA, the European Space Agency (ESA), and the Institute of Space and Astronautical Science (ISAS) of Japan, has recently created this new resource for use in physics and astronomy courses or by other interested users. A sister site to its popular Exploration of the Earth's Magnetosphere site (described in the August 19, 1998 Scout Report for Science and Engineering), Stargazers to Starships explores gravity with three tutorials: exploring the Astronomy of the Earth's motion in space, Newtonian mechanics, and Spaceflight and Spacecraft. Each tutorial is composed of short, individual lessons on key concepts. Additional resources include a glossary, an annotated timeline, and tips for teachers.
