When I first read about techniques for aerial balloon photography, I thought it sounded like a fun project…
Then I read about these teenagers, who sent their camera into space:
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 20 miles above the ground, the Meteotek team of IES La Bisbal school in Catalonia completed their incredible experiment at the end of February this year…
…”The balloon we chose was inflated with helium to just over two metres and weighed just 1500 grams,” said Gerard. “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.
“We took readings as the balloon rose and mapped its progress using Google Earth and the onboard radio receiver,” said Gerard.
“At over 100,000ft the balloon lost its inflation and the equipment was returned to the earth…

Some students from Oklahoma State sent their Pentax on a similar journey. Their description of how it was done is in English.
