True, in a sun trailing orbit it is much less dangerous but it is a

There is no principle broken here.

Er... If this orbit was chosen for a spacecraft it means it is
interesting since it keeps the spacecraft away from earth and from the
torque complications of having a rotating planet underneath you.


Incorrect, it was chosen to avoid light from the earth



And, in the page you pointed me to, there is ALSO this
sentence:

This orbit avoids gravitational perturbations and torques inherent in an Earth orbit, allowing for a more stable viewing platform.

OK?

But precisely this characteristics make it interesting for a wide range
of spacecraft that would as interested as this one in getting away from
earth.
What do we know about what kinds of orbits will be interesting
to scientists 100 years from now?

It is not interesting for a wide range of spacecraft.


What do you know?

According to NASA: (http://kepler.nasa.gov/sci/design/orbit.html)

<quote>
An Earth-trailing heliocentric orbit with a period of 372.5 days provides the optimum approach to meeting of the combined Sun-Earth-Moon avoidance criteria.
<end quote>

Any other spacecraft that wants undisturbed fine pointing would chose
that orbit too!


Objects stay in space essentially forever. There is no wind, no erosion
NOTHING, it is empty.

So, this means that there is nothing for this cover to run into and it
will affect nothing, which is right


Yes. I even agree with that. There is nothing until we put ANOTHER
spacecraft in an earth trailing orbit!

This thinking led us to the situation of today where
there was just a 10 minute alarm to save the ISS from an
incoming debris.

That is in earth orbit. Not the same thing. Kepler is in solar
orbit


Yes. But 30 years ago there was NOTHING up there. 30 years later
we have it so crowded that it is a risk for the astronauts!


No. It is adding debris to the trailing orbits of the earth.

You don't understand. It is in solar and not earth orbit


Of course it is a solar orbit, that is the definition of
an earth trailing orbit! An orbit around the sun that trails
the earth!


This spacecraft is beginning to pollute a NEW realm of space,
I already understood that. What is appalling is that you
do not understand such a simple fact.

No, you don't understand. It is not a 'new" realm of space.

Yes, it is the space behind the earth orbit. We have already polluted
all of the earth orbit.

GREAT

Now we start with the space behind the earth.


It is a
inconceivability large part of space, where there is nothing in it.

As it was earth orbit 30 years ago.

What is appalling is your complete lack of understand and you are
blowing this way of proportion. You need to study spaceflight in
general.


You are just throwing words around, nothing else.
