All Gaia CCDs delivered
Today the 130th and last Gaia CCD has been accepted, hence completing the pool of Flight Model and Flight Spare devices. This completes a phase of Gaia development which started more than 8 years ago with the manufacturing company e2v technologies. After assembly, integration and testing the Gaia focal plane will eventually contain 106 CCDs providing the detection of the anticipated billion objects.

10th anniversary of the publication of the Concept and Technology Study Report (CTSR)
The scientific success of Hipparcos demonstrated the feasibility of accurate global astrometry from space. It led to a proposed M3 mission, Roemer, but finally not accepted due to its modest accuracy gain over Hipparcos. Gaia was proposed in response to a call for ideas for a cornerstone mission. Approval of a 'Concept and Technology Study' for Gaia was given in 1996. The CTSR was published 4 years later, in July 2000, demonstrating that the goals to be achieved by Gaia were feasible and within the budget.

Workshop on Binaries and Multiple Systems (Brussels, 17-18 May)
A workshop on post-Gaia scientific investigations on double and multiple stars will take place in Brussels, 17-18 May. With roughly 100M binaries and multiple systems detected and modelled by Gaia, the community has to be ready to handle data sets which it is not used to. The goal of this kick-off workshop is: (a) from the Gaia DPAC side, to make the community fully aware of what Gaia is likely to achieve in terms of binaries and multiple systems; and (b) from the community side, to make DPAC aware of its expectations and potential problematic cases which might have been overlooked so far, and what they expect in their field of research in the Gaia era. For more information, visit the workshop web site.

European Science Foundation (ESF) funded GREAT research networking programme started
The objective of GREAT is to provide opportunities to the wider science community in the exploitation of the Gaia mission by supporting a science-oriented network addressing the scientific issues in which Gaia will have a major impact. The newly launched ESF funded GREAT research network, which will run until February 2015, will fund a wide range of community networking events.
The first open round of calls, for workshops, conferences, exchange visits and training schools, will be released in early March 2010 - with deadlines of 4 June 2010. Proposals to support networking events in science areas where Gaia will have a significant impact, will be welcome.
More information can be found on the GREAT website or at the ESF pages. Specific information related to the upcoming GREAT ESF RNP calls is located at http://www.great-esf.eu/participate/participate.html.

A million CPU hours for Gaia simulation
GASS is one of the CU2 data generators, in charge of producing Gaia-like telemetry data to be injected in the processing chain, from IDT onwards. In order to run the GASS simulations needed for the DPAC End to End (E2E) testing, a total of 1,100,000 CPU hours have been allocated by the Red Española de Supercomputación (RES, the Spanish Supercomputing Network) in MareNostrum for the next four months. This will allow the generation of 18 months of telemetry for a scaled-down version of the sky suitable for this E2E testing. For more information, visit the following link.

Gaia Project / DPAC Interface Control Document approved
The Gaia Project / DPAC Interface Control Document (GAIA-EST-ICD-05489) has been approved by DPACE and ESA and is now available on Livelink. The history of this document goes back to June 2006, when Carine Babusiaux first issued Requests for spacecraft and instrument specifications (GAIA-CD-TN-OPM-CB-010). After the first meeting on 21 February 2008 to discuss the DPAC needs, a list of items required by DPAC, and to be provided by ESA, has recently been agreed upon, covering the optical configuration, the detectors/electronics and focal plane assembly, the spacecraft attitude, the payload data handling unit, video processing unit, and telemetry, the basic angle monitoring and wavefront sensor devices, and the atomic clock.

Ten years Tycho-2 Catalogue
The Tycho-2 Catalogue of the 2.5 million brightest stars in the sky was released on the 8th of February 2000, and it has become one of the four most popular of all astronomical catalogues (see Erik Høg's recent note at the website where also publications and data are available). Tycho-2 contains positions, proper motions and two-colour magnitudes for the stars covering the entire sky. Positions and magnitudes were based on observations from 1989 to 1993 with Hipparcos. The Tycho-2 positions and 100 years of ground-based astrometry contained in more than 140 catalogues were utilized to obtain the proper motions.
