Astronaut (and Former Astronaut) Hams

To our readers:  We have made every effort, through exhaustive research, to maintain as accurate a list as possible, of the many men and women who have amateur (ham) licenses among those who are or have been astronauts and/or cosmonauts. 

We will always remember 01-FEB-2003, the date of the tragic loss of Space Shuttle Columbia over Texas, minutes before mission STS-107 was to end with a safe landing at the Kennedy Space Center in Florida.  This catastrophe resulted in the deaths of seven astronauts, including three who were licensed radio amateurs: Mission Specialists Kalpana Chawla, KD5ESI; David M. Brown, KC5ZTC; and, Laurel B. Clark, KC5ZSU.

Our sincerest condolences go out to the families of the Columbia Seven and their families.

(Note: During 2002, the callsign RS0ISS was being used on the International Space Station.)

A very nice article with links on NASA's website entitled "Ham Radios in Space" can be found here.


The NASA headquarters worldwide Mir info web site has a history of each cosmonaut crew which has occupied Mir.

Most astronaut biographies can be found here; unfortunately, NASA does not provide a very easy search capability at this site.


Here is a link to information on the ISS the International Space Station.


Crewmembers (listed by Expedition #) are found at: Expedition Crews.


Biographies of the astronauts and cosmonauts connected with the joint U.S. - Russian programs can be found at the NASA Headquarters web site.  Credit: Glenn Swanson, KB1GW

NASA's (AESP) Aerospace Education Services Program has at least four radio amateurs, Ota Lutz, KD5UQZ, Joan Sanders, KD5UQW, and Angelo Casaburri, KD5UQS, Linus Guillory, KD5WXN, travel to schools and museums as AESP representatives.  AESP specializes in providing free professional development workshops for teachers of science, mathematics, geography and technology. Workshops introduce participants to hands-on activities and NASA curriculum support materials.  


Contact the American Radio Relay League, the national association for amateur radio, in Newington, CT, for further information about amateur (ham) radio.
