Satellites, Launchers and Landers
A great deal of space exploration is performed by autonomous craft. They have mapped remote planets and even landed to send surface data back to Earth. Satellites have changed the world of communication, earth observation and, through global positioning systems, everyday navigation. This collection, with contributors such as ESA and NASA, looks at satellites, remote exploration and also the launchers that get them into space.
This Science upd8 activity draws on the 1957 launch of the satellite Sputnik 1 which heralded a new stage in human exploration and prompted the development of rockets in the Space Race. In this role play, students consider the benefits and costs of space exploration.
