Already in May of this year, NASA began launching research balloons from the Esrange space station outside Kiruna. On Tuesday, the last and largest balloon landed in Canada.
The purpose of the project is to collect data on cosmic radiation.

– All four balloons have gone well. They have received an incredible amount of data and it has been good data, says Mattias Abrahamsson, business developer and balloon expert at Esrange in Kiruna.
High
The balloons have been at an altitude between 37 and 45 kilometers up. Mattias Abrahamsson explains that they want the balloons to reach such high altitudes as the earth’s atmosphere otherwise interferes with the radiation they want to research.
– They have mainly looked at cosmic radiation and astronomical experiments and then they want to be as high up as possible. says Mattias Abrahamsson.
