The ESA successfully landed a small lab on Comet 67P ("Chury"). The lander features 10 instruments which may provide important clues to the origin of life. Two DC motors made by maxon motor are on board the mission. The Swiss-based drive specialist provided two DC motors, with a diameter of 13 mm each. These motors will be used to lower the APXS instrument to the ground. The APXS is an alpha x-ray spectrometer to be used to record the chemical composition of Comet Chury and provide information on the presence of key elements such as carbon and oxygen.
