Vega’s PRETTY CubeSat: unlocking satnav for Earth data

Our planet is being continuously bathed in radio signals from satnav satellites – which are useful for much more than just navigation. Dedicated space missions acquire these signal reflections to amass valuable environmental information. The shoebox-sized PRETTY CubeSat, flying on Europe’s next Vega launcher, will investigate a new frequency and novel observation angle to better measure the rate of climate change – at the same time as gathering radiation data on its surrounding space environment.
