MOURA instrument is a three-axis magnetometer and gradiometer designed and
developed for Mars MetNet Precursor mission.
The initial scientific goal of the instrument is to measure the local
magnetic field in the surroundings of the lander i.e. to characterize the
magnetic environment generated by the remanent magnetization of the crust
and the superimposed daily variations of the field produced either by the
solar wind incidence or by the thermomagnetic variations. Therefore, the
qualification model (QM) will be tested in representative scenarios like
magnetic surveys on terrestrial analogues of Mars and monitoring solar events, with
the aim to achieve some experience prior to the arrival to Mars.
In this work, we present a practical first approach for calibration
of the instrument in the laboratory; a finer correction after the comparison
of MOURA data with those of a reference magnetometer located in San Pablo de
los Montes (SPT) INTERMAGNET Observatory; and a comparative recording of a
geomagnetic storm as a demonstration of the compliance of the instrument
capabilities with the scientific objectives. |
