Observations made with the OMEGA imaging spectrometer onboard Mars Express reveal very strong signatures of sulfates and ferric oxides in Aram Chaos. The presence of these chemicals may indicate that significant amounts of water were present in this area in the past.

Data from the joint ESA/NASA Ulysses mission show that the Sun has reduced its output of solar wind to the lowest levels since accurate readings have become available. This current state of the Sun could reduce the natural shielding that envelops our Solar System.
