An International Space Station Expedition 15 ARISS school contact has been planned with participants at Heidelberg University for Applied Sciences, Heidelberg, Germany on 24 Sep. The event is scheduled to begin at approximately 08:00 UTC.

The contact will be a telebridge between stations NA1SS and WH6PN. The contact should be audible in Hawaii. Interested parties are invited to listen in on the 145.80 MHz downlink. In addition, the audio should be available via IRLP and EchoLink. The participants are expected to conduct the conversation in English.

Currently, we build a CubeSat-Satellite called HeidelSat. It should measure cosmic rays. The launch is planned for September 2009. Also we build a ground station for it with a satellite dish having a diameter of 3,4m. It will operate in July 2007. In that project we do involve children from the age of 12 years onwards. Currently the do meet every Wednesday to prepare for the radio amateur license exam which will take place on September 7th. Also, of course students are involved in that project. If we can have an organized radio contact with the International Space Station, we would then invite all schools around Heidelberg area for that event. We plan to present films about Sputnik, Gagarin, Apollo11, Jules Verne's story "The travel to the Moon". Also we plan to invite Prof. Messerschmitt from Stuttgart to give a talk. And of course we present our HeidelSat.
