I write this post today not from the confines from my room in Stockholm but from a hostel room overlooking the mountains ranges of Abisko national park. A weekend hunting for the so far elusive Aurora and a retreat from REXUS =) =P. This week was a really busy week for the optics team. We began searching for parts of the optical system that will be used in the experimental and tracking components of the Free Falling Unit (FFU) Rx. In order to complete spectroscopy one FFU (ISAAC Rx) must track and record the IR light emitted from the other FFU (ISAAC-Tx).
The optical system under design will capture the light emitted from the ISAAC-Tx and split it. The optical light will be directed to a camera for the tracking of the Tx and the IR radiation sent to the detectors to complete the experimental objectives of the ISAAC mission.
Speak to you soon! =) Happy hunting,
