Students Take Stunning Images Of Earth Using Cheap Camera And Balloon
Teenagers with a £56 camera and latex balloon have managed to take stunning pictures from 20 miles above Earth.
Proving that you don't need Google's billions or the BBC weather centre's resources, the four Spanish students managed to send a camera-operated weather balloon into the stratosphere. Taking atmospheric readings and photographs, the Meteotek team of IES La Bisbal school in Spanish Catalonia completed their incredible experiment at the end of February this year.
Building the electronic sensor components from scratch, Gerard Marull Paretas, Sergi Saballs Vil, Martm Gasull Morcillo and Jaume Puigmiquel Casamort were able to send their heavy duty £43 latex balloon to the edge of space and take readings of its ascent.
Under the guidance of teacher Jordi Fanals Oriol, the budding scientists, all aged 18 to 19, followed the progress of their balloon using hi-tech sensors communicating with Google Earth
'We were overwhelmed at our results, especially the photographs. To send our handmade craft to the edge of space is incredible.' To successfully conduct the experiment, the team had to account for a wide variety of variables and rely on a lot of luck.
'The balloon we chose was inflated with helium to just over two metres and weighed just 1,500g,' said Paretas. 'It was able to carry the sensor equipment and digital Nikon camera which weighed 1.5kg.'However, when we launched at 9.10am on that morning, the critical point for the experiment was to see if the balloon would make it past 10,000m, or 30,000ft, which is the altitude that commercial airliners fly at.
Due to the changing atmospheric pressures, the helium weather balloon carrying the meteorological equipment was expected to inflate to a maximum of nine and a half metres as it travelled upwards at 270 metres per minute. 'At over 100,000ft, the balloon lost its inflation and the equipment was returned to the earth
