The image will be exhibited permanently in the new access building by the Pregny gate in the Palais des Nations compound. Mr Sergei Ordzhonikidze, the Director General of the UN Office in Geneva, accepted the mosaic on behalf of the United Nations from Dr Volker Liebig, ESA Director of Earth Observation Programmes, donating it on behalf of the European Space Agency.
The image is a mosaic of global land cover images taken by the MERIS instrument onboard ESA’s environmental satellite which shows the entire planet ‘in its true colours’. To produce the mosaic, a total of 1561 satellite orbit passes were used over the period May-November 2004. “Forests, desert, mountains and oceans are clearly visible. The mosaic shows the state of the planet at the beginning of the 21st century from a perspective only satellites can deliver”, said Volker Liebig.
Launched in 2002, Envisat is the largest Earth observation spacecraft ever built. It carries ten sophisticated optical and radar instruments to provide continuous observation and monitoring of the Earth's land surface, atmosphere, oceans and ice caps. Envisat data combined collectively provide a wealth of information on the workings of the Earth system, including insights into factors contributing to climate change.
The Medium Resolution Imaging Spectrometer (MERIS) measures the solar radiation reflected by the Earth, at a ground spatial resolution of 300m, with 15 spectral bands in the visible/near-infrared regions and programmable in terms of width and position. It provides global coverage of the Earth every three days.
ESA and UNOSAT, the UN project concerned with satellite imagery access and applications, are partners in several initiatives and programmes aimed at extending the use of satellite technologies to facilitate the work of the international community and UN agencies in particular. UNOSAT, which forms part of UNITAR, the United Nations Institute for Training and Research, promotes projects and programmes designed to enable developing countries and local communities in particular to gain access to such technologies and supports humanitarian aid activities.
ESA cooperates closely with UN specialised agencies. Since 2000, it has launched initiatives with a view to using observation technology to support the implementation of key multilateral environmental agreements such as the United Nations Framework Convention on Climate Change. Since the Johannesburg World Summit on Sustainable Development in 2002, ESA has been cooperating closely with UNOSAT and UN agencies on sustainable development projects and projects geared to Global Monitoring for Environment and Security (GMES) service development.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
