Managing your probes and landers and rovers on Mars

My dear friends
every tool has its purpose
at frist I was mad that my unmaned probes had only black and white vision and really poor photos they made
but then I udnerstood:they were needed only to see wher the landing spots shall be on Deimos and Mars

then considering that Deimos has no atmo,my EAS probes were deployed on Mars
but wait! there are 2 types of locations
ones with a big circle around them where the probes can analyze the atmo while descending
and others where a lander is required
a lander does not have wheels only legs:)
so it can not move around
you can use it to probe the air and soil and to laser some rocks and that is it

but a lander has a much bigger radius than a rover and a much bigger robotic arm and it costs much less

my rovers costs 20 million dollars each
and they are used not for probing air and soil but for seeing crashed parties
