"Meteotek was our experiment to see if we could accurately measure the Earth's atmospheric conditions at 30,000 metres, take pictures to prove the experiment and then recover the instruments attached to the balloon after its deflation," said team leader Paretas, 18.
"We were overwhelmed at our results, especially the photographs. To send our handmade craft to the edge of space is incredible."
