Hello, Geny5!! Space exploration has affected the economy by simple things such as technology and airline businesses. In the technology field, portable devices, like cell phones, mostly started with portable communication systems in space. Whereas the airline business, a lot of the technology in airplanes today was used in order to travel to space and for exploration. If you think about it, when astronauts talk to each other in space, they are using portable technology like cell phones. In airplanes, they have oxygen and the ability to control how to stay in the air/fly/land, like rockets and other things NASA uses. Culturally, it would boil down to technology, again. Many things in our lives today are centered around technology, just like space exploration. They have to have the technology to get them into space and come back down. If it wasn’t for space exploration, we wouldn’t have computers, cell phones, or even solar panels. I hope this helped!! Have a great evening!! :)
