A Marineris Vallis sample siteConsideration is given to the choice of a Marineris Vallis canyon site in that it may offer the widest possible variety of martian units with a minimum amount of roving. Researchers support this in the classical comparison of Marineris Vallis with the Grand Canyon of the U.S.A. It is well-known to American geologists that most of the geological units in the U.S. may be found here in one section. Might not the Martian canyon offer a similar selection but only more so in view of its much greater size. A system whereby this sampling may be effected is proposed based on a combination of a skip with a wire-line core-barrel method. The final design will depend more on the completeness of the core to be taken as the entire section is that long that the weight of the core of the whole section may well be prohibitive for return to Earth unless several returns are envisaged. The wire-line is operated from a static head-gear in much the same way as an oil well implying a lander not needing mobility of any kind - a destinct advantage.
