The space balloon was part of a marketing stunt to promote the S10. The idea was that people back on Earth could take a selfie via their own phone, then upload it to a dedicated Samsung site. That would beam up to the space balloon containing a Galaxy S10. The photo would then beam back, showing the selfie against a backdrop of planet Earth.
Actress Cara Delevigne was the first to have her selfie snapped in space.
In a statement Samsung said the satellite suffered from adverse weather conditions: "Earlier today, Samsung Europe's SpaceSelfie balloon came back down to earth."
"During this planned descent of the balloon to land in the US, weather conditions resulted in an early soft landing in a selected rural area. No injuries occurred and the balloon was subsequently retrieved. We regret any inconvenience this may have caused."
