On 4 October 2023 a team of University of Seville students launched a 3U CubeSat-format pseudosatellite from the León aerodrome on a B2Space stratospheric balloon. The flight reached 19 km and lasted about 2 hours and 39 minutes, and the vehicle was recovered in working condition north of Gordaliza del Pino.
The vehicle was powered by monocrystalline solar panels and rechargeable batteries. The mission was part of the FyCUS 23 "Fly Your CubeSat" programme, led by Professor Francisco Rogelio Palomo Pinto.
