67P, Rosetta mission and Fraunhofer IZFP


For over 10 years it has been on the road: the Rosetta spacecraft – one of the most fascinating and most demanding enterprises of the European space travel.

After the launch on March 2, 2004, the space probe set out its journey to the comet 67P / Churyumov-Gerasimenko. En route, it performed several complex maneuvers, called "gravity assist" (three times using the Earth and one time using Mars as accelerators), which gave it the necessary "momentum" for the long journey to the outer regions of the solar system.

Rosetta - comet chaser


Being an exponent of the Saarland R&D community, the Fraunhofer Institute for Nondestructive Testing IZFP is part of this important and eventful project. One of the tasks of the landing module Philae is the examination of the elastic and plastic properties of the comet ground.

The required transducers have been developed by the Fraunhofer IZFP specifically for CASSE (Comet Acoustic Surface Sounding Experiment). CASSE is one of two instruments used for the measurement of elastic and/or plastic properties of cometary matter, whose knowledge allows conclusions on the composition and strength of the ground.

The extensive knowledge and experience of the Institute in nondestructive materials characterization by ultrasound were incorporated into the test system which was specially adapted for the comet landing.

The four-year investment of Fraunhofer IZFP on this project led to a close collaboration with colleagues from the other participating European teams. For this purpose the participating German institutes were financially supported by the Federal Ministry of Economic Affairs and Energy (BMWi). 

With the landing of Philae on 67P the project will soon hit its peak while the evaluation of the information obtained will be a scientific long-term project.

Rosetta is an ESA mission with contributions of the ESA members and the NASA. The Rosetta landing module Philae was subscribed by a consortium under the leadership of DLR, MPS, CNES und ASI.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Klima-Satellit: Mit robuster Lasertechnik Methan auf der Spur

Hitzewellen in der Arktis, längere Vegetationsperioden in Europa, schwere Überschwemmungen in Westafrika – mit Hilfe des deutsch-französischen Satelliten MERLIN wollen Wissenschaftler ab 2021 die Emissionen des Treibhausgases Methan auf der Erde erforschen. Möglich macht das ein neues robustes Lasersystem des Fraunhofer-Instituts für Lasertechnologie ILT in Aachen, das eine bisher unerreichte Messgenauigkeit erzielt.

Methan entsteht unter anderem bei Fäulnisprozessen. Es ist 25-mal wirksamer als das klimaschädliche Kohlendioxid, kommt in der Erdatmosphäre aber lange nicht...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: Die Schweiz in Pole-Position in der neuen ESA-Mission

Die Europäische Weltraumagentur ESA gab heute grünes Licht für die industrielle Produktion von PLATO, der grössten europäischen wissenschaftlichen Mission zu Exoplaneten. Partner dieser Mission sind die Universitäten Bern und Genf.

Die Europäische Weltraumagentur ESA lanciert heute PLATO (PLAnetary Transits and Oscillation of stars), die grösste europäische wissenschaftliche Mission zur...
