On 6 February, ESA reviewed the status of the spacecraft and the results of the test campaigns that were carried out over the past year. Following the review, the spacecraft teams were given the green light to start the launch campaign, the final phase of spacecraft activities on Earth.
Built by Thales Alenia Space leading a host of subcontractors from across Europe, the Herschel spacecraft and its instruments were thoroughly tested at ESA’s Space Research and Technology Centre (ESTEC) in Noordwijk, the Netherlands, during 2008. The spacecraft, now packed in its container, will be transported to Kourou by plane on 11 February 2009.
Planck, also built by Thales Alenia Space and its subcontractors, was initially tested at Thales Alenia Space in Cannes and at ESTEC, Final tests took place at the facilities of the Centre Spatial Liège, Belgium. The spacecraft will be transported to Kourou by plane on 18 February 2009.
Once at the Guiana Space Centre, the two spacecraft will undergo their final checks and be prepared for launch. Herschel and Planck are scheduled to launch into space in a dual launch configuration by an Ariane ECA rocket on 16 April 2009.

Gravitational wave kicks monster black hole out of galactic core

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
