Eleven space technologies tested in space for one year
Conditions in space are very different to those on Earth large temperature variations, microgravity and cosmic radiation. Components of satellites, the
Technologies for use in space must be reliable; otherwise, the risk inherent in employing them is too great. Verification of their performance in space is of critical importance, given the extreme environmental conditions prevalent there, stated DLR Executive Board Chairman Johann-Dietrich WÖrner as he described the OOV programme, the core element of which is the TET series of satellites. With the successful flight of the TET-1 satellite, we are in a position to enable the various organisations involved to qualify their payloads directly for use in space, explained WÖrner at the TET-1 launch. In the past, new technologies could only be tested on Earth. Space-related influences are many and varied; for example, high-energy particles can damage the on-board electronics of a satellite, thereby interrupting the transmission of television or mobile phone signals from space.
Bridge between ground-based testing and utilisation in space
TET-1 (TechnologieerprobungstrÄger-1, Technology Testbed-1) weighs 120 kilograms and has a payload capacity of 50 kilograms.
