  • ROVING ACROSS MARS: SEARCHING for EVIDENCE of FORMER HABITABLE ENVIRONMENTS Michael H
    PERSPECTIVE ROVING ACROSS MARS: SEARCHING FOR EVIDENCE OF FORMER HABITABLE ENVIRONMENTS Michael H. Carr* My love affair with Mars started in the late 1960s when I was appointed a member of the Mariner 9 and Viking Orbiter imaging teams. The global surveys of these two missions revealed a geological wonderland in which many of the geological processes that operate here on Earth operate also on Mars, but on a grander scale. I was subsequently involved in almost every Mars mission, both US and non- US, through the early 2000s, and wrote several books on Mars, most recently The Surface of Mars (Carr 2006). I also participated extensively in NASA’s long-range strategic planning for Mars exploration, including assessment of the merits of various techniques, such as penetrators, Mars rovers showing their evolution from 1996 to the present day. FIGURE 1 balloons, airplanes, and rovers. I am, therefore, following the results In the foreground is the tethered rover, Sojourner, launched in 1996. On the left is a model of the rovers Spirit and Opportunity, launched in 2004. from Curiosity with considerable interest. On the right is Curiosity, launched in 2011. IMAGE CREDIT: NASA/JPL-CALTECH The six papers in this issue outline some of the fi ndings of the Mars rover Curiosity, which has spent the last two years on the Martian surface looking for evidence of past habitable conditions. It is not the fi rst rover to explore Mars, but it is by far the most capable (FIG. 1). modest-sized landed vehicles. Advances in guidance enabled landing Included on the vehicle are a number of cameras, an alpha particle at more interesting and promising places, and advances in robotics led X-ray spectrometer (APXS) for contact elemental composition, a spec- to vehicles with more independent capabilities.

Sodium perchlorate, goethite, pyrite, ferric sulfate, regular and high capacity 28 granular ferric oxide, and forsterite were added to a Mojave Mars Simulant (MMS) base in order 29 to match the mineralogy, evolved gases, and elemental chemistry of Rocknest.

For more than 15 years Mars Express has been conducting global surveys of the surface, the atmosphere and the plasma environment of the Red Planet. The Trace Gas Orbiter, the first element of the ExoMars programme, began its science phase in 2018 focusing on investigations of the atmospheric composition with unprecedented sensitivity as well as surface and subsurface studies. The coordination of observation programmes of both spacecraft aims at cross calibration of the instruments and exploitation of new opportunities provided by the presence of two spacecraft whose science operations are performed by two closely collaborating teams at the European Space Astronomy Centre (ESAC). In this paper we describe the first combined observations executed by the Mars Express and Trace Gas Orbiter missions since the start of the TGO operational phase in April 2018 until June 2019.
