An American aviator named Wiley Post was one of the pioneers in pressurized spacesuit design. I want to become an astronomer. But I have a fetish, I'm a material girl and I want to be wealthy. Technology is putting knowledge to practical use. Nearly everything an astronomer does involves technology in some form.
Satellites view the Earth and send communications.
Telescopes are used to view the planets, stars, galaxies, comets. Probes are sent to planets to bring back information about planet surfaces. Space shuttles are used to send men into space to learn more about living in space. Astronomers use the knowledge and instruments they have to gather new knowledge, and then to make it work for us, in ways like storing energy from the sun, and perhaps someday living in space. The astronauts' clothing is designed to be comfortable and functional.
