Aboard it will  have four scientific instruments: two of them - MIRI and NIRSpec - being  European deliveries with contributions from MPIA. MIRI has been built by  a European science consortium involving more than a dozen scientific  institutes - among them MPIA. [[BR]][[BR]]MIRI includes an imager and two spectrometers capable of doing imaging,  coronography as well as spectroscopy. MPIA has been responsible for the filter wheel and the two  dichroic-grating wheel mechanisms of the instrument. They have been  designed, partly manufactured and tested at MPIA with great involvements  of the design engineering department, the mechanical and the electronics workshops, respectively. The  scientific performance has been tested extensively in 2011 in the UK by  the MIRI test team.[[BR]] [[BR]]MIRI has been delivered to NASA in 2012, since then the test team is  supporting the cryo-test campaigns at the Goddard Space Flight Center,  is preparing the calibration pipeline and science cases. The talk will give an overview of MIRI's history at MPIA, its  scientific performance and the future till the launch in 2018.

    4242|| '''24.04.2015''' || '''Kai Weidlich (Airbus D&S)''' || '''BELA - ESA's first Laser Altimeter for Planetary Research[[BR]][[BR]]'''[[BR]]The space-qualified design of a miniaturized laser for the !BepiColombo laser altimeter (BELA) will be presented. It will form an integral part of a larger geodesy and geophysics package on board the Mercury Planetary Orbiter (MPO) of the !BepiColombo mission.[[BR]][[BR]]The laser facilitates pulsed operation at 10 Hz repetition rate and at 1064 nm wavelength. The laser design consists of a pair of diode-laser pumped, actively q-switched !Nd:YAG rod oscillators encapsulated into dry synthetic air. The system delivers at least 300 million laser pulses with 50 mJ energy and 5 ns duration. It will be launched in 2016 and, after a six-years cruise, will start recording topographic data from orbital altitudes between 400 km and 1500 km above Mercury's surface. Critical qualification issues of the BELA Laser comprise reliable operation of laser diodes, accurate  transmitter-to-receiver alignment, stable pulse energy and stable beam divergence over 300 million laser pulses.[[BR]][[BR]]Starting design work at Carl Zeiss Optronics Oberkochen in 2008 the BELA Laser project was completed at Airbus DS Optronics with flight spare delivery in 2014.[[BR]][[BR]]Talk: German[[BR]]Slides: English[[BR]]Questions: German, English ||
