Importance of space exploration to man
Spacecrafts continue to provide information about conditions in space in particular about the weather . Reports derived from weather satellite can act as warning systems about impending storm. It helps us to gain more knowledge about our planet earth. e.g. a scientific satellite known as Vanguard 1 sent back pictures, which showed that the earth was slightly pear-shaped. Communication satellites like Telstra and Relay have made it possible to send television programmes and telephone calls over much longer distances. In 1965, the US achieved another momentous feat in space communication . The mariner4 in a deep space probe sent back pictures of mars that were taken as it passed the planet. Some space exploration offers possibilities without limit. Planets themselves may have metals and other resources that men on earth need. Information about outer space may make it possible to make rain and make long-range weather forecast more accurately than before. Some scientists are opti...
