... For the operational period up to now, Mars Express has been making its closest approaches to Mars predominantly in the daytime portion of its orbit. ... The MARSIS radar's scientists are mainly collecting data about the upper layers of the Martian atmosphere, or 'ionosphere', which is the highly electrically conducting layer that is maintained by sunlight. ... When a radio wave crosses the boundary of different layers of 'material', an echo is generated and carries a sort of 'fingerprint' from the specific materials. ... During night-time observations, like those performed briefly last summer immediately after deployment, it is possible for MARSIS to use all frequencies for scientific measurements, including the lowest ones, suitable for penetrating under the soil of Mars. ...
