After these flights, amateur radios were often taken on the shuttles, as many as twenty-five before the program became known as ARISS. Licensed hams were able to participate during their free time. ;Shuttles that Participated and Licensed Astronauts


Educational uses

Most amateur radio operators used SAREX to speak with licensed astronauts during their down times. SAREX, however, has been very educational for young students from kindergarten to fifth grade involved in a program similar to young astronauts, in which elementary school children learn about astronauts' daily activities and what it is like in space. Students also have had the opportunity to communicate via video when the shuttles have had suitable equipment. Teachers have found out about how to link their classes with the SAREX program through the Amateur Radio in Space Guide distributed by NASA.


Licensing

An amateur operator license is needed before operating an amateur station. The license can be obtained from the U.S.
