Modelling a satellite’s fiery fall to Earth

Atmospheric re-entry of satellites is a destructive and difficult to predict process, as the satellite body breaks up into various segments which are scattered and subject to aerothermal heating. There are many uncertainties involved – not only...

Clean Space working with Earth Observation mission desi...

Sharing is caring: that goes for the space industry too – especially when it comes to tackling the common problem of orbit debris. Working on innovative solutions to make future satellites compliant with space debris mitigation, ESA’s...
