- Abstract
A data archive for spaceflight experiments was developed and implemented at the DLR Microgravity User Support Center (MUSC) using the HyperTest platform. HyperTest was originally developed by Werum for automotive Industry. The purpose of the spaceflight experiments data archive is to establish an entire information system, which is capable to store flight and ground data for long times according to the ESAs Data Policy for Space Flights and to provide an user friendly access to all experiment related mission data. The archive stores experiment data, experiment relevant mission data, project information and documentation, as well as software application tools for data evaluation. HyperTest manages information about circumstances of data acquisition, where data is stored and available, tools for data online evaluation, relationships between data, and valuable information about the mission project. It also allows storing and using project specific software application tools (e.g. video data processing and evaluation) HyperTest uses meta data to organize the storage in meaningful logical relationships. The meta information about experiments are searchable and lead to the data. In addition, a full text search is implemented. Searching through documents leads to information and data linked to it. In summary, a combination of navigating in logical structures and searching quickly leads to the data. Utilisation rights can be defined to read, write and change data, which allow different user groups particular archive views and data access rights. This allows treatment of confidential data and information according to ESAs spaceflight data policy. The archive is web based and allows sharing data and information between investigator groups. Data security is established by using dedicated networks and the access is established via secured entry points and services. The HyperTest Data Archive is currently tested in a first version at MUSC. It is implemented for two space projects, Rosetta-Lander and the Microgravity Facility EML. The paper is giving a survey on the archive functions and capabilities. Examples will be given from the archive application for the EML payload. The EML project will use the archive for the next parabolic flight campaign of EML in May 2006, where data will be directly stored during the flight campaign and the archive will be used for post mission data distribution, quick-look access and experiment evaluation purposes.
