Nasa did a fly around the Moon, if I remember correctly pryor to the
Moon landing mission.

You don't remember correctly. NASA did two orbital missions of the Moon
prior to landing, Apollo 8 and Apollo 10.

The whole point here is that a flyby doesn't give you all that long of a
time to do much in terms of "local" remote control.

There is an additional thing that a flyaround mission to Mars could
do. They could "TEST LAND" the planned Mars mission lander, remotelly
naturally. That would be necessary precurso to an actual landing.

No, they might, if they timed it accurately, but keep in mind during the
entire time of this 'test land' they are either accelerating towards Mars or
moving away, so you have to possibly adjust your timing as the speed of
light delays change.

They might join orbit, instead of making it a flyby. But that is only
an alternative option.

And as for this being necessary, hardly. In fact you've replaced the actual
scenario (landing a manned vehicle on Mars) with a made-up one (remote

You need to mind that to land on Mars is both at the same time, more
difficult than landing on Earth and than landing on the Moon. A manned
landing has never been done on that solar system body, but plenty of
times on Earth and number of times on the Moon.

It would be mad not to test the technologies necessary for a
successful landing on Mars, with some sort of a real test.

At this time, the task is though impossible, i.e to land humans on
Mars.

Ellse the risk would be quite mad.

Someone said that the people might be stranded on Mars.

Maybe. Look at Case for Mars. There's far worse places to be stranded than
Mars.

Provided with enough power, you have access to enough resources. (Besides,
landing resources is pretty easy in the big picture, the delta-v ain't all
that bad compared to any other options).

A far more
likelly failure outcome is that they become a crater on Mars. The
landing is the critical point of the endevour, at least the first of
the critical points.

Now, for the short term the Moon looks attractive. After all we have
the technology to land there today, and it is closer to Earth to boot,
and to top that going there is a lot cheaper; yet operational lessons
learned there are applicaple everywhere ellse, when operating on
airless bodies.
