Amateur Radio on the International Space Station

The primary goal or ARISS is "to promote exploration of science, technology, engineering, and mathematics topics" and inspire individuals to pursue careers in STEM.

It is also possible to send digital data to the ISS via laptop computers, similar to an email communication, using radio frequencies instead of telephone or cable connections [citation needed].
