On January 4, 2025, the Volgograd Planetarium hosted a fascinating lesson of the Alcyone astronomy club under the guidance of experienced radio amateur Alisa. Young researchers, students in grades 5–10, created VHF antennas with their own hands, studying the work of electromagnetic waves in practice.
The work proceeded as in a real scientific project: two participants were engaged in calculating satellite flights and setting up software, and four young men and women were engaged in assembling antennas of the 435–438 MHz range. A special role was played by young “quality control employees”, who carefully checked the finished structures, as if in a real production facility.
After the antennas were assembled, they were tested to receive signals from the small spacecraft “UMKA-1 (RS40S)”.
In addition to the technical part, the lesson took on a creative note: the girls created charming drawings on a space theme.
On January 6, 2025, schoolchildren from the Temnikovsky District of the Republic of Mordovia visited the Mission Control Center in the city of Ruzayevka, where they learned how to work with small spacecraft launched under the Space Pi program at a master class on satellite control led by Dmitry Pashkov (R4UAB) .
The culmination of the master class was that the drawings made by children from Volgograd were processed and uploaded to the small spacecraft "VIZARD-METEO (RS38S)" by students from Mordovia for their transmission from space. Anna and Maria also developed a satellite flight cyclogram, which will ensure the successful transmission of pictures via the SSTV protocol. These works will decorate and complement the New Year's broadcast, becoming a symbol of inspiration for all participants.
