The THEMIS mission is a five-satellite Explorer mission whose primary objective is to understand the onset and macroscale evolution of magnetospheric substorms. The five small satellites were launched together on a Delta II rocket and they carry identical sets of instruments including an electric field instrument (EFI), a flux gate magnetometer (FGM), a search coil magnetometer (SCM), a electro-static analyzer, and solid state telescopes (SST). The mission consists of several phases. In the first phase, the spacecraft will all orbit as a tight cluster in the same orbital plane with apogee at 15.4 Earth radii (RE). In the second phase, also called the Dawn Phase, the satellites will be placed in their orbits and during this time their apogees will be on the dawn side of the magnetosphere. During the third phase (also known as the Tail Science Phase) the apogees will be in the magnetotail. The fourth phase is called the Dusk Phase or Radiation Belt Science Phase, with all apogees on the dusk side. In the fifth and final phase, the apogees will shift to the sunward side (Dayside Science Phase). The satellite data will be combined with observations of the aurora from a network of 20 ground observatories across the North American continent. The THEMIS-B (THEMIS-P1) and THEMIS-C (THEMIS-P2) were repurposed to study the lunar environment in 2009. The spacecraft were renamed ARTEMIS (Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon’s Interaction with the Sun), with the P1 and P2 designations maintained.

As cultural competence center for the region, the Landesarchiv serves as the repository for records of cultural and historical value and assures the access of archives in Baden-Wuerttemberg as part of the cultural heritage. It identifies, collects, and preserves state records and makes them available to all those who are interested in historical records. The Landesarchiv houses archival collections ranging from deeds from the Middle Ages to digital sources of our time (databases, e-mails, internet pages). The Landesarchiv has already been providing diversified access to archival collections via internet and is actively working on research and presentation of the history of Southwest Germany. The archival collections of the Landesarchiv convey the cultural and historical diversity in Southwest Germany. Each holding is unique and characterizes the distinctive history of the people and the region. This makes the Landesarchiv an irreplaceable reservoir of knowledge and experience with remarkable quantitative dimensions: The Landesarchiv houses about 146 shelf kilometers of documents and books, 310 thousand charters as well as 350 thousand maps and plans completed with photographs and audio-visual records. Electronic data are stored in the digital stack of the Landesarchiv.
