The MUPUS Instrument for Rosetta mission to comet Churyumov-Gerasimenko.

Project name: The MUPUS Instrument for Rosetta mission to comet Churyumov-Gerasimenko.
Consignee: The German Aerospace Center (DLR), The European Space Agency (ESA),The Ministry of Science and Higher Education (MNiSW)
Leader of the project: T. Spohn
Participants in the project: M. Banaszkiewicz (Co.I), M. Hłond, S. Gadomski, J. Grygorczuk, J. Krasowski, W. Marczewski
Cooperation: The German Aerospace Center (DLR), The European Space Agency (ESA), Westfälische Wilhelms-Universität Münster
Timeframe of the project:

MUPUS (MUlti PUrpose Sensor for surface and subsurface science)- is an international comet experiment conducted by prof. Tilman Spohn of Planetary Institute, University of Münster.

It is a scientific program of nine investigation systems on board the lander PHILAE, which is about to land on the comet in 2014. 

Information about all the instruments are available at

ThermalResearchis intended to help determine the energy balance conditioning the evolution rhythm of comets and to contribute to the identification of physical properties and composition of its nucleus.

Polish contribution to the experiment is substantial. This includes scientific and technical aspects of the project, including manufacturing and technical qualification of the instrument. The instrument is actually a multifunctional robot. A number of solutions used in it are unique.

The construction is meant to work in extreme conditions - in a vacuum, with great range and temperature gradients, with resistance to huge overload (even required 1000g), and at the same time with the expectation of a good reliability after several years of space travel.

It is worth noting that the technical objectives were achieved with very low resources usage: 1500 grams of weight and about 2W power supply. The robot conducting a number of mechanical operations, including a very energetic action hammering the probe into the ground, needs only as much power as a good flashlight.

We attentively watched NASA's Deep Impact mission-its results suggest that the ice surface material can be brittle.It is a good outlook for us- our probe would not penetrate hard ice.When a decision was taken in the 90's there was no such belief. Please remember us in 2014.
