Mars InSight scheduled to land near the equator in 2018 already will be a
great geology mission, but the recent discovery of large water deposits near
the equator on Mars raises the possibility it could also be a great
astrobiology mission:

Water ice found near Mars’s equator could entice colonists and life-seekers.
Find also poses climate puzzle.

Mars Insight is scheduled to land in Elysium Planitia at 4°N 136°E:

Here is a map from the Icarus paper showing the regions of high water(ice)
content:



Notice in the second panel in the image there is a region of high water
indicated in blue near the Mars Insight landing site. However, for Mars
landers you can't get the landing position exactly right and there is
unfortunately a larger area above and to the right of very low water content
indicated in red that is also near the landing site. The question is could
they stick the landing near the high water region?

One of the Mars Insight instruments might be ideal for detecting the near
surface water since it will include a subsurface borer able to drill down to
5 meters:



But what instruments could be used to distinguish liquid water from ice
water?

In view of the possibility of liquid water existing near surface, I would
also like to see a true microscope put on the lander. Of all the landers
sent to Mars none included a true optical microscope. The best optical
resolution of the imagers sent to Mars so far were no better than that of a
geologist's hand lens.
