LuxSpace announced: 4M mission completed


Bremen, Betzdorf 4th November 2014


The Manfred Moon Memorial Mission (4M) was successfully finished on Monday, after more than 250 hours of operation. Shortly after the separation of the main Chinese satellite, the 4M probe was switched on. During its path around the moon, all messages were sent several times and received by at least 29 radio amateur stations around the globe. Marco Fuchs, CEO of OHB said: "It was really amazing to see that 4M was able to bring so many people around the world together.” 

The radiation experiment provided a large volume of data, which is currently investigated by LuxSpace. Unfortunately, the experiment died during its second path through the Van Allen Belt after 215 hours. Concerning the triangulation experiment quite an improvement in the understanding of the working principle was achieved towards a future operational application. "Even though not everything worked perfectly, we have learned so many things for future missions and it should not be forgotten that the job was done with a very limited budget and a time frame of 5 months", said Jochen Harms, Managing Director of LuxSpace. 

The 4M probe has now entered into a highly elliptical Earth orbit with a period (one orbit around Earth) of 14 days - the apogee (largest distance from Earth) will be 386.000 km, the closest distance (perigee) will be 85.000 km. No re-entry of 4M is currently expected. LuxSpace is working on a refinement of the orbital parameters.

After 438 hours of continuous operation, 4M’s primary batteries are empty. Depending on illumination, 4M may wake up from time to time and restart transmitting. Given, the temperature conditions, 4M operated four times longer than the designed lifetime. Here at LuxSpace, we want to thank all radio amateurs for the reports and for the tracking during the last weeks. They were a central part of this successful mission.
