The scope of this mission is to launch and operate two balloon flights; MIPAS-B/TELIS (Michelson Interferometer for Passive Atmospheric Sounding), operated by the FZK-IMK Karlsruhe Germany and,
TWIN, developed by the University of Frankfurt. The Twin gondola also carries a HALOX-B chemical conversion fluorescence detector measuring ClO/BrO, developed and operated by the Forschungszentrum Jühlich, and a pico-SDLA tunable diode laser water vapor instrument operated by CNRS, France.

The scientific objective
The scientific objective of the flights is to obtain measurements of stratospheric trace gases within the arctic stratospheric polar vortex as part of continuing research of ozone destruction. Read more here.

Mission Profile
The flights will be conventional with the entire operation taking place within line of sight from Esrange. The balloons are between 150.000 m3 - 400.000 m3 and produced by Zodiak (France). Payloads will range from 400 to 800 kg with desired float altitudes of 30 to 35 km as long as possible (minimum 5 hours). The launches must take place on days when the polar vortex is directly over Esrange as the scientists wish to measure within this air mass. 

The launches and flights are performed within the framework of the EuroLaunch cooperation between SSC/Esrange and DLR/Moraba.
