Successful ARISS Contact for CRA Pozohondo, Nava De Abajo, Spain successful


Tuesday October 16 at 09:30 UTC, which is 11.26.52 CEST, students from CRA Pozohondo, Nava De Abajo, Spain established ARISS contact with NASA astronaut Sunita Williams KD5PLB on board the International Space Station. Astronaut Sunita Williams KD5PLB operated with the ISS callsign NA1SS. This was a telebridge contact performed by Luis Anibal Funes amateur radio station LU8YY, located in Argentina.


This school is officially named CRA ( Colegio Rural Agrupado) because it is located in a small village called Nava de Abajo and it only has  30 pupils from kindergarten ( 3 to 5 years old) to the last level of Primay School ( 11- 12 years old pupils). The building is  small and there are only four teachers, so the students are organized in mixed levels: Kindergarten, 6-7 years, 8-9 years and 10-11 years of age.


Regarding this activity, it is remarkable to note the keen interest teachers and students show for the knowledge of the Universe. They have developed astrophotography, astronomy ,´astro-tales´ and radioham studios. You can learn more on this website:
