Thermal and mechanical material properties determine comet evolution and even solar system formation because comets are considered remnant volatile-rich planetesimals. Using data from the Multipurpose Sensors for Surface and Sub-Surface Science (MUPUS) instrument package gathered at the Philae landing site Abydos on comet 67P/Churyumov-Gerasimenko, we found(More)
The main objective of the IBIS modeling activities is the generation of the IBIS spectral response matrix. This generation will be done step by step by firstly constructing " calibrated model " of each IBIS subsystems. A " calibrated model " is defined as a GEANT Monte-Carlo model, further checked by intensive corresponding calibration. These calibrated(More)
In the paper a two decades long development of low velocity penetrators and devices derived from them in Space Research Centre is presented. The case study is penetrator developed for the Philae lander on the Rosetta that laid the fundament for further constructions. Two main Rosetta penetrator mechanisms described here are: the insertion mechanism that is(More)
The upcoming lunar lander missions, for example Chang'e 2 from CNSA and several mission proposals and studies currently under consideration at NASA (e. offer new possibilities to measure the thermal properties of the lunar regolith and to determine the global lunar heat flow more accurately than it is hitherto known. Both properties are of high importance(More)
Introduction: The objectives of the Heat Flow Probe, one of the instrument in the Lunar Geophysical Instrument Package (LGIP) [1] is to make direct measurements of the steady-state thermal energy flux flowing from the interior of the planet to its surface, and carries rich information about its deep thermal structure, bulk chemical composition, and(More)
[1] This paper discusses test results obtained in both laboratory and terrestrial environment conditions for the ‘‘Multipurpose Sensors for Surface and Sub-Surface Science’’ Thermal Probe (MUPUS-TP), which has been developed for the European Space Agency Rosetta cometary rendezvous mission. The probe is intended to provide in situ long-term observations of(More)
