Journal ArticleDOI
Rosetta lander - Philae: Implications of an alternative mission
Stephan Ulamec,S. Espinasse,B. Feuerbacher,Martin Hilchenbach,D. Moura,H. Rosenbauer,H. Scheuerle,R. Willnecker +7 more
TL;DR: In this paper, the authors proposed a new mission scenario for the Rosetta Lander, because the nucleus of the comet 67/P Churyumov-Gerasimenko is expected to be considerably larger than that of P/Wirtanen.
Journal ArticleDOI
Landing on small bodies: From the Rosetta Lander to MASCOT and beyond
Stephan Ulamec,Jens Biele,Pierre-W. Bousquet,Philippe Gaudon,Koen Geurts,Tra-Mi Ho,Christian Krause,Caroline Lange,Rainer Willnecker,Lars Witte +9 more
TL;DR: The first dedicated comet Lander is Philae, an element of ESA's Rosetta mission to comet 67/P Churyumov-Gerasimenko, currently foreseen for November 2014.
Journal ArticleDOI
Hopper concepts for small body landers
TL;DR: In this paper, the authors present the results of a study for a small (∼10 kg) hopper device, optimized for a mission to a relatively small asteroid, which may, e.g., be considered as part of the Japanese Hayabusa 2 mission, to be launched in the 2014/15 timeframe.
Journal ArticleDOI
Preliminary studies concerning subsurface probes for the exploration of icy planetary bodies
Melanie Treffer,Norbert I. Kömle,Günter Kargl,Erika Kaufmann,Stephan Ulamec,Jens Biele,Alexander Ivanov,O. Funke +7 more
TL;DR: In this paper, the authors consider the application of such "melting probes" for exploring the structure of ice sheets in extraterrestrial environments and compare the results with tests in a terrestrial environment.
Journal ArticleDOI
Rosetta lander Philae – Landing performance and touchdown safety assessment
TL;DR: In this paper, the authors describe the simulation and analysis work on Rosetta lander Philae's touchdown dynamics which was done to support its landing site selection process, and the actual flight data were used to review and discuss the applicability of the presented simulation-and analysis scheme.
