The Arabia Terra region on Mars is populated with numerous
craters, filled with deposits of various materials that, over
time, have become severely eroded. The latest images acquired by
the HRSC camera show many features of this kind, known as
'yardangs', in Danielson Crater; the different types of material
these contain could be explained by changes in the climate. The
Robotics and Mechatronics Center (RMC) at the German Aerospace
Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is
exhibiting at AUTOMATICA, the leading international exhibition
for automation and mechatronics, which is being held in Munich
from 22 to 25 May. Even though it doesn’t quite qualify as a
'proper' planet, the second most massive asteroid in the Solar
System, Vesta – which has a diameter of approximately 530
kilometres – exhibits numerous planetary characteristics. This

mission, published in the journal Science on 11 May 2012. The
Dawn spacecraft has been orbiting Ves
