World’s first wooden satellite slated for launch in Finland. UPM Plywood, Arctic Astronautics and Huld announce today a joint mission to launch the first ever wooden satellite, WISA Woodsat, into Earth’s orbit by the end of 2021. The satellite electronics is mostly based on Kitsat that is a fully functional one unit CubeSat (roughly 10 →
It seems that Earth’s magnetic field is weakening and changing at the moment. The magnetic North is moving towards Siberia and South Atlantic Anomaly weakening the Earth’s magnetic field. There is some fear that the weakening is causing technical problems for satellites and could have other effects. Here are some links to news on this →
European’s own satellite navigation system has been down for days. It shouldn’t cause any serious issue but must be annoying for anybody that has something to do with this 10 billion Euro EU project. I saw first notes on this on following article (Note that the Galileo system is still very new and not as →
