ISS Science for Everyone

Science Objectives for Everyone
Creating, Preparing, and Launching Small Spacecraft during Extravehicular Activity (RadioSkaf) uses a decommissioned Orlan spacesuit equipped with a ham radio transmitter and a compact disk containing messages and images from students around the world. After being released during extravehicular activities, the suit will transmit a ham radio signal and then re-enter the Earth’s atmosphere and burn up. Students and hobbyists from around the world can tune in to the signal to identify the transmitted words and image. This investigation will not only inspire the next generation of explorers but can help bridge the cultural gap of people around the globe.
Science Results for Everyone
ISS hand-me-downs are out of this world. Spacesuits that have outlived their useful life contain pressurization hardware that can be used to design simple student research devices for mini-satellite missions. This investigation developed a procedure for assembling small satellites from these suits and launching them during extravehicular activity. The mini-satellites were used to successfully send service and mission information to amateur radio stations on the ground. Using amateur radio stations as part of the mini-satellite command and telemetry system, people around the world can receive information from the mini-satellites at little cost.

Applications

Space Applications
During the experiment, a microsatellite was successfully launched from aboard the ISS during extravehicular activity; microsatellite equipment was also tested experimentally in autonomous flight. Viewing and listening to the data received made it possible to confirm the stability of satellite signal reception on Earth from the ISS.

Earth Applications
The results obtained during the experiment sessions proved the capacity for student-created space objects with various target applications using recycled components and not requiring large material expenditure. During the experiment, sessions were conducted to receive information from the satellite at ham radio stations on the ground, thus confirming the capability to receive data from the International Space Station (ISS) by all ham radio communication stations on the ground located in the area of radio coverage of the microsatellite.

Results/More Information

During the RadioSkaf experiment, data was obtained for the development of future projects to launch similar satellites as a part of youth education programs. A procedure was developed for assembling and launching satellites such as RadioSkaf from the ISS during extravehicular activity. Verification of technical solutions on receiving radio signals from a chaotically tumbling object, the operating lives of spacesuit batteries, temperature changes in the spacesuit without the operation of a temperature control system, and other parameters, were completed.

The Kedr amateur microsatellite was a new stage of the RadioSkaf experiment, which began in 2006. This experiment was carried out within the framework of the UNESCO student program on space education for the youth around the world. Audio satellite recognition signals and photographs of the Earth were received by ham radio stations on the ground in various countries.
