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 video from NASA shows why satellites are used and how they work. The video describes the four components of a satellite, the processes of uplinking and downlinking, and the information that satellites provide to scientists. The segment also explains the difference between geostationary and orbiting...
Humans have landed on the Moon. These images, from NASA, show some of the Lunar rovers that have been involved in manned Lunar explorations and some that may be developed for future missions to the Moon.
This simple activity from NASA allows classrooms to study rocket stability as students construct and fly small "indoor" paper rockets. The rockets can be used for a range of activities into forces and movement in which students collect data and interpret the results.
The space shuttle has been used by NASA as a re-usable orbiter since 1981. The programme's last flight is scheduled for 2011. These resources show all stages of a mission, from launch to landing. It includes a video of the launch of the space shuttle Atlantis.
