    <title language="eng">The past decade of ZERODUR® glass-ceramics in space applications</title>
    <abstract language="eng">For the past four decades, ZERODUR® glass ceramics has flown on many satellites including the prominent&#13;
space missions METEOSAT, Hubble Space Telescope, CHANDRA, and LISA pathfinder. Firstly, this unique&#13;
material is chosen as mirror substrate for high precision optics due to its extreme thermal stability. Its near-zero thermal expansion over a wide temperature range of several tens of Kelvin is homogenous within the entire&#13;
volume. This enables control of the ZERODUR®’s surface profile at the 10-picometer level. SCHOTT has conducted comprehensive material characteristics studies on the mechanical properties and the radiation environment effects experienced in realistic orbits to define the suitability of ZERODUR® to survive both high loads during launch and to support long-term missions, respectively.&#13;
Besides these advantageous material properties, this glass-ceramics can be extremely light-weighted by&#13;
precision grinding enabled by the new SCHOTT competence center for machining and metrology. In this paper,&#13;
we will continue to trace the recent developments of ZERODUR® glass ceramics as space material in the context&#13;
of selected missions flown since 2009 and those anticipated. Major milestones such as the LISA pathfinder&#13;
mission are discussed. Furthermore, we outline the viable use of ZERODUR® for great observatory&#13;
architectures for IR/O/UV spaceborne telescopes.&#13;
The objective of this paper is to supplement an earlier review of the use of ZERODUR® for space applications&#13;
in the past decade and to summarize the latest progress and results of material studies toward very efficient&#13;
production capabilities for high-performance light-weighted mirror substrates.</abstract>
