Previous projects

STRAtospheric PLatform EXperiment

The STRAPLEX balloon campaigns offered students from European universities and high schools the opportunity to send experiments into the stratosphere using balloons filled with helium.

The STRAPLEX project was developed by the University of Porto, Portugal, in collaboration with ESA's Education Office.

Young Engineers' Satellite YES2

YES2 is a demonstration of new technologies. It was the first time in history a thirty kilometre long tether was deployed in space and a parcel was shot back down to Earth from a tether.

The three-part experiment was mounted on the outside of the Russian research capsule Foton M3. The Foton M3 was launched into Earth orbit from the launch base at Baikonur, Kazakhstan on 14 September 2007.

SSETI Express

The objective of the SSETI Express project was to deploy CubeSat pico-satellites, take pictures of the Earth, act as a test-bed and technology demonstrator for ESEO hardware, and also function as a radio transponder for the global amateur radio community.

This micro-satellite, roughly the size of a washing machine, was placed in low-Earth sun-synchronous orbit by a Russian Cosmos 3M satellite from Plesetsk, Russia on 27 October 2005.
