Capabilities of Philae, the Rosetta Lander
Jens Biele,Stephan Ulamec +1 more
TL;DR: In situ (and sample return) space missions are the most promising tools to investigate the origin and evolution of comet nuclei as mentioned in this paper, and the ROSETTA Lander mission is one of the most successful space missions to date.
Journal ArticleDOI
Development and testing of a pyro-driven launcher for harpoon-based comet sample acquisition
Stefan Völk,Stephan Ulamec,Jens Biele,Matthias Hecht,Peter Lell,Josef Fleischmann,Sebastian Althapp,Markus Grebenstein,Joseph A. Nuth,Donald Wegel,Walter Smith,Lloyd Purves,Douglas S. Adams,Stuart Hill,J. C. Leary,Harold A. Weaver,Scott A. Sandford +16 more
TL;DR: The scientific and technological background of the CORSAIR mission, an overview of the development, design and testing of the launcher, and the launcher theory are introduced explaining the entire reaction chain: initiation → gas dynamics → SARP motion.

Consert for Asteroid -radar tomography of Near Earth Asteroid
Alain Herique,D. Plettmeier,W. Kofmann,Stephan Ulamec,Jens Biele,J.-P. Gautail,Pierre Beck,Jeremie Lassue,Antonella Barucci,Patrick Michel +9 more
TL;DR: Consert for Asteroid is a radar to instrument the Mascot lander, which is proposed in the frame of future Near Earth Asteroid missions as discussed by the authors, and the problematics of the NEA is reviewed in order to demonstrate the interest of low frequency radar sounding.
Radar Tomography of Asteroids
Alain Herique,Antonella Barucci,Jens Biele,T. M. Ho,Wlodek Kofman,C. Krause,Patrick Michel,Dirk Plettemeier,J. Y. Prado,J. C. Souyris,Sonia Zine,Stephan Ulamec +11 more
TL;DR: In this paper, the internal structure of NEAs is investigated using radar tomography, which is the most promising way to probe the NEA internal structure in order to characterize its composition and its heterogeneity from decimetric to global scale.
