SpaceGRID is an ESA study aimed at identifying the potential benefits of Grids to the ESA community and defining a road map for the implementation of this technology within ESA. Grid technology is an emerging computing infrastructure that is intended to provide uniform access to a set of distributed networked resources that would otherwise be incompatible. Depending on the Grid application, the resources may be large-scale computational systems, data-archives or shared facilities constituting a collaborative working environment.
One area being considered by the study is Solar System Research (SSR), encompassing activities in Solar, Solar Terrestrial and Planetary research. This is an active area of ESAs current (Cassini/Huygens, Cluster and SOHO) and future (SMART-I, Mars-Express, Rosetta, Double Star, Bepi-Columbo and Solar Orbiter) programme. In the case of SSR the main benefits of the SpaceGRID are expected to come from the provision of uniform mechanism for the location, manipulation, access and sharing of online data. This will free the end user from many of the laborious routine data handling tasks allowing more time to concentrate on the analysis. The ability to search multiple, distributed datasets and return a single combined data product will simplify event identification and open the way for new areas of interdisciplinary analysis. A key part of this will be the ability for individual users and groups to plug-in to the SpaceGRID not only to retrieve data from existing archive sites but also to make available their own data via a local Grid-site.
The SSR requirements for SpaceGRID are being developed by a group of scientists and software engineers who already have a background in the SSR field and are actively involved in current ESA projects covering the three SSR disciplines. Input from and participation by the community from the outset is seen as an important step to ensuring the success of SpaceGRID. This questionnaire provides one means of collecting these inputs.
The European Grid of Solar Observations (EGSO) is a project funded by the European Commission under its Information Society Technologies (IST) programme. EGSO is a Grid testbed and aims to create a Grid of solar data archives, making them appear as though they were a single data source. To do this it will federate solar data archives across Europe (and beyond); create tools to select, process and retrieve distributed and heterogeneous solar data; provide mechanisms to produce standardized observing catalogues for space and ground-based observations; and provide the tools to create a solar feature catalogue. The EGSO project is due to start in early 2002 and will last for 3 years. For more information about EGSO, see the EGSO web site at URL http://www.mssl.ucl.ac.uk/grid/egso.
Many of the problems that EGSO will tackle are very similar to those that SpaceGRID needs to solve. The creation of EGSO will therefore act as a testbed of some of the ideas and concepts that will be result from the SpaceGRID study project. This questionnaire will also help define the user requirements of the EGSO project.
Please fill in as much of the questionnaire as you are able. If your work covers several different areas and the inputs cannot be consolidated into a single response then complete a separate questionnaire for each area.
Some guidance notes are available to help you through the process of completing the questionnaire. Within the form you will find links and info buttons, that will take you to the corresponding information in the guidance notes.
If you would prefer to complete the questionnaire off-line then you can print out this form or download the MS Word or PDF versions. Please send the completed forms to: SpaceGrid SSR Team, R25 1.88, Space Science and Technology Dept., Rutherford Appleton Lab, Oxfordshire, OX11 0QX, UK.
