Second Galileo spacecraft prepares for launch

07.03.2008
Yesterday, members of the media visited ESA-ESTEC, the agency's European Research and Technology Centre, to see and learn about GIOVE-B, the second Galileo in-orbit validation satellite, before it is packed for shipping to the launch site.

GIOVE-B has successfully completed its test campaign and will depart from ESTEC on 11 March. The spacecraft will be flown to Baikonur, in Kazakhstan, from where it will be carried into orbit by a Starsem Soyuz/Fregat launch vehicle. The launch is scheduled for 04:16:02 local time on 27 April (00:16 CEST, 22:16 UTC [26 April]).

Media day

Around 50 members of the press attended the media event. Giuseppe Viriglio, ESA's Director of Telecommunication and Navigation, welcomed the visitors and gave an introduction to ESA's navigation programmes. Paul Verhoef, Head of the Galileo Unit in the Directorate-General for Energy and Transport of the European Commission, presented the Galileo Programme.

Javier Benedicto, ESA's Galileo Project Manager, introduced GIOVE-B and the Galileo in-orbit validation phase. Groups of guests then visited the ESTEC test centre, to see GIOVE-B at the conclusion of its tests, and the Navigation Laboratory, which will play a major role in validating signals from the satellite.

The spacecraft

GIOVE-B will test novel, key technologies for the Galileo system, such as the high-precision passive maser clock and the triple-channel transmission of navigation signals. Instruments onboard the satellite will measure the radiation and spacecraft charging environments.

GIOVE-B will be able to transmit a signal adopting a specific standard (known as MBOC), in accordance with an agreement reached only a few months ago by the European Union and the United States for their respective systems.

The spacecraft was built by a consortium lead by Astrium GmbH (Germany) as satellite prime, with Thales Alenia Space (Italy) as subcontractor for satellite assembly, integration and test. Telespazio (Italy) will be in charge of the operations in orbit.

The way forward

Following on from GIOVE-B, the first four satellites of the operational constellation are under development. They are scheduled for launch in 2010 and will enable a system-level verification of the Galileo design.

In November 2007, the European Union Transport Council reached the following conclusions on the future development of Galileo:
the European Commission will be responsible for the overall management of the programmes as the European Global Navigation Satellite System (GNSS) Programme Manager
ESA will act as procurement agent and prime contractor for Galileo
the full operational capacity (30 satellites and associated ground stations) is targeted by 2013
Galileo deployment and EGNOS operations are fully funded by the EU; €3.4 billion are allocated over the period 2007 to 2013

An agreement between the European Commission and ESA is being prepared which will address, in particular, the respective responsibilities and the detailed implementation of the Galileo deployment.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
