Answer:
better computers
improved communications
ultra-strong plastics
weather satellites
Step-by-step explanation:
Many of the ultra-strong plastics and heat-resistant ceramics used in sports and industry were developed for use in space.
Some of the smaller and faster computers available today were a result of the need for such computers in tiny space ships.
The pictures taken by weather satellites help meteorologists to make more accurate weather predictions. These satellites also help monitor more accurately the level of air pollution.
Signals broadcast from navigation satellites help navigators map the position of ships at sea.
Communications satellites send radio messages, telephone calls, and television programs between distant parts of the earth.
