After more than 15 years of development at international level lead by ESA, SpaceWire has become the workhorse for high data rate on-board communications, not only for ESA missions but for other space agencies (NASA, JAXA, ROSCOSMOS) and for the space industry. This technology has become a de facto standard for payload systems and is now being used for avionics. The capability provided by SpaceWire to develop data handling systems based on high-speed networks rather than low-speed buses allows much greater performance but implies mastering much more complex communication schemes.

Imaging at frequencies in the Terahertz (THz) region of the electromagnetic spectrum has progressed rapidly in the past few years and even commercial terrestrial systems have started to emerge. Lately there is significant interest in stand-off detection and imaging. The technology push is aimed at the development of multi-element multi-frequency THz cameras with high image and spectral resolution. These systems will find wide-spread use in both space and terrestrial applications.

Stainless steels are major manufacturing materials used in spacecraft and ground support structures on applications requiring corrosion resistance including storage and handling of liquids and waste, propulsions systems, components within thermal protection systems and fasteners such as high-reliability and high strength bolts. Passivation of stainless steel has two purposes: 1) it is necessary to remove ?free iron?

There is a fundamental issue in the electronic box design that the power density is increasing. In addition, system integrators prefers the dry thermal interface since it allows the unit to be dismountable. However, the thermal interface has a conductive limit where the only method of increasing the heat transfer would be to increase the surface area as well as the contact pressure and reducing the interface filler thickness.

The objective of the Aeolus/EarthCARE Aerosol Assimilation Studies (A3S) project was to allow assimilation of the Aeolus L2A lidar backscatter data, also paving the way for the assimilation of EarthCARE products. Since the Aeolus and EarthCARE missions were not yet launched at the time of the study, demonstration datasets based on model data (MOCAGE model for the aerosols and the IFS for the clouds) and a one-day dataset based on CALIPSO data (reprocessed at the UV wavelength and with the Aeolus orbit data) was created.

Potential concepts and their related technologies for a Next Generation Gravity Mission (NGGM) as a follow-up to the GOCE mission are currently being studied. The mission will be designed to monitor the variations of the Earth?s gravity field to a level that allows the study of mass transport processes not only in solid Earth but also at the Earth surface layer and in the lower atmosphere.

The building block shall maintain the two novel but proven technologies of the previous activity pumping at 885 nm as well as multisegmented high dopping crystals). The new technical objectives of this activity are: extending its energy up to 10-15mJ, with a repetition rate from 50 Hz up to 100 Hz maintaining same pulse length, beam spatial and temporal stability and M2. To that purpose, a more powerful pumping-diode stack shall be used as well as a specially designed Nd:YAG multi-segmented crystal rod of higher diameter and increased doping concentration.

The precision welding of metallic joints plays an important role in the production of components for space applications. In order to meet the demanding levels required, metallic joints must be produced which have the correct dimensional tolerance, are free from defects and exhibit the correct mechanical and corrosion performance. In particular, in propulsion systems all valves and pipes have welds which must be leak tight and prevent safety hazardous propellants from leaking.

The first steps have been taken to establish a non-explosive, harmless Indium-based 100W electric propulsion system for small and medium satellites. The activity successfully developed a breadboard that included all necessary functions for controlling a micro thruster, including temperature sensing and control, generation of the high voltage supplies for the ion emitter and extractor as well as heating and bias voltage supply for the charge balancing.
