After over 1.5 years of collecting dust COSIMA was shut down on 27.09.2016, as ROSETTA was on its final way down to the comet. We are very proud about the instruments which worked during the whole mission and collected an impressive amount of scientific data.

Mai 2016: vHS is currently developing the LED calibration unit (NI-CU) for the Near Infrared Spectrometer and Photometer (NISP) instrument for the ESA Euclid Mission. The Structural Thermal Model was delivered at the end of last year and has now been integrated into the NISP Development Model. The photograph shows the calibration unit (NI-CU) with gold plating on the main NISP structure (black).
The development of the NI-CU requires the manufacture and qualification of Infrared LEDs to be operated in a space environment at cryogenic temperatures. The use of LEDs sources is a novel approach replacing the traditional technology of tungsten filament lamps and integrating spheres. Our new solution provides a more compact and mass/power efficient method. In order to qualify LEDs for use in space, significant testing of LED performance at cold temperatures must be undertaken as well as more traditional component testing. Special test systems have been developed by vH&S to allow for cryogenic performance testing of multiple parts.
Flight units are due to be delivered next year. The work is performed under contract to our customer Max Planck Institut für Astronomie and is funded by DLR.

On the 3 December 2015, a Vega rocket from Kourou, French Guiana was launched carrying ESA's Lisa Pathfinder satellite. The satellite, a technology demonstrator for a future gravitational wave observatory mission, carries a Command & Telemetry Interface (CTI) card designed and built by vH&S to be part of the Charge Management System (CMS) for the Blackett Laboratory, Imperial College London.

The satellite measures fluctuations of passing gravity waves by measuring the fine relative movements of two identical cubic test masses, which are "free-falling" within the satellite. Both masses must be isolated from any other forces generated by the environment or satellite: A significant component of this are electrostatic forces exerted by charge build-up on either mass as a result of the interaction of passing cosmic rays.

The CMS's role is to purge any charge on the test masses by illuminating the test masses with light from one of its eight ultra-violet lamps. The state and operation of the CMS is controlled and monitored by the CTI card designed and built by vH&S.

The CTI cards features a MIL-STD-1553B standard interface and a dedicated FPGA which interprets commands and collects housekeeping data from all 8 UV lamps via a backplane within the same enclosure.
