The solution to the Mars Age Paradox is fairly simple: the Mars cratering in recent geologic time, the unknown free parameter in these LCG models applied to Mars, must be allowed to be much larger, approximately 4xLunar. When this adjustment of the Mars cratering rate is done, the paradox largely disappears. The mean surface age of the Northern Lowlands of Mars becomes approximately ½ billion years, matching the mean age of the young MMs. However, this creates a new problem for the Mars community, it transforms the Red Planet from being a simple place that died geologically in its early days, to a lively, complex, dynamic place, that appears to have been Earthlike until recent geologic times. The Mars age paradox is thus solved, but in its place is a host of more profound puzzles emerges. These puzzles center around the new, younger ages of liquid water erosion landforms, spanning almost the whole geologic age of Mars, that, given our new younger ages for Mars surfaces, must now be recognized as being formed right up until recent geologic times.

On Mars this is reflected, to a degree, in the dichotomy of MM crystallization ages, either of very old or very young geologic ages, though the young MMs, statistically, much outweigh the older ones. While this statistical problem may be resolved by the discovery of more older MMs in the meteorite collections, such as possibly the CI carbonaceous chondrites Brandenburg (1996), we can concentrate on the younger MMs as a group and assume they came from the younger Northern Martian Lowlands. However, even when this is done the Mars age paradox remains. Liquid water channels or lake/sea beds, (see Figure 2) are found on terrains of Mars spanning the geologic ages from the ancient, heavily cratered
