In the framework of the ESA’s Aurora Exploration Programme and, in particular, of the ExoMars mission, the Raman Laser Spectrometer (RLS) will be in charge of performing out planetary Raman spectroscopy for the first time. The instrument is located inside the Rover at the Analytical Drawer (ALD) and will analyze powdered samples obtained from the Martian subsurface in order to determine the geochemistry content and elemental composition of the minerals under study. After the RLS instrument successful qualification, the Flight Model (FM) development and the acceptance verification activities started. Among the different units RLS is composed on, i.e. its three main units that are interconnected by optical fibers and electrical harness, iOH (Internal Optical Head), SPU (Spectrometer Unit) and ICEU (Instrument control and Excitation Unit) which also contains the Raman excitation laser diode, iOH FM information can be found in this paper. RLS iOH unit is in charge of focusing the Raman excitation signal onto the sample, receiving the Raman signal emitted by the sample and focusing this signal in the output optical fiber that is directly connected to SPU unit. As for the rest of RLS instrument FM subunits, and before their final assembly and system level tests, RLS iOH FM exhaustive and complete characterization process was carried out, not only at room conditions but also at relevant environmental conditions: vacuum condition along the operational temperature range with acceptance margins (from -50 to 8ºC). In this paper, and after to carry out the RLS iOH FM proper integration and alignment process, the activities accomplished during the performance verification and the obtained results are reported on
JEM-EUSO (Extreme Universe Space Observatory on the Japanese Experiment Module) is an advanced observatory that will be on-board the International Space Station (ISS) to observe the UV photon tracks produced by Ultra High Energy Cosmic Rays (UHECR) with energy above 1019 eV. JEM-EUSO will detect the electromagnetic and hadronic components of the Extensive Air Showers (EAS) generated as the result of the UHECR colliding with atmospheric nuclei. Atmospheric monitoring to obtain data, us cloud coverage and cloud top altitude, is crucial for energy estimation of an extreme energy particle. Accordingly JEM-EUSO will include and Atmospheric Monitoring System (AMS) to observe the Earth atmosphere continuously in the FOV of the main telescope. The AMS will comprise an InfraRed CAMera (IRCAM), a LIDAR and JEM-EUSO slow data.
Raman Laser Spectrometer (RLS) is the Pasteur Payload instrument of the ExoMars mission, within the ESA’s Aurora Exploration Programme, that will perform for the first time in an out planetary mission Raman spectroscopy. RLS is composed by SPU (Spectrometer Unit), iOH (Internal Optical Head), and ICEU (Instrument Control and Excitation Unit). iOH focuses the excitation laser on the samples (excitation path), and collects the Raman emission from the sample (collection path, composed on collimation system and filtering system). Its original design presented a high laser trace reaching to the detector, and although a certain level of laser trace was required for calibration purposes, the high level degrades the Signal to Noise Ratio confounding some Raman peaks. So, after the bread board campaign, some light design modifications were implemented in order to fix the desired amount of laser trace, and after the fabrication and the commitment of the commercial elements, the assembly and integration verification process was carried out. A brief description of the iOH design update for the engineering and qualification model (iOH EQM) as well as the assembly process are briefly described in this papers. In addition, the integration verification and the first functional tests, carried out with the RLS calibration target (CT), results are reported on.
