449. A belly of NASA's space shuttle
original uploaded on 2018/05/27 18:05 (GMT)
NASA had space shuttles,
which could go to space and back to the Earth repeatingly for many times,
and in which we, humans, could stay on orbits around the Earth.
(Their last mission was operated on 2011.)
Black parts on NASA's space shuttle's bottom are
thermal insulators for a re-entry sequence.
Its weak point is easy to be damaged by hit shocks.
(For that reason, some astronotes died in an accident.
I am sorry to hear that.)
Their space shuttle's missions are ended now.
But I tried to re-think this weak point of NASA's space shuttle.
I think that it has big possibilities for suffering damages,
wherever of any rockets its thermal insulators are,
if it is easy to be damaged as such.
I want to cover a belly of NASA's space shuttle by some guards.
Our demand is not having any damages at a time of its re-entry sequence.
So I think I take off its guard at that time.
when I take off its guard
the best timing I think is
when the belly of NASA's space shuttle is
in a high temperature condition during its re-entry.
My idea's point is that,
I want to put
a stuff that will vapor during a re-entry sequence
but is easy to spray on its thermal insulator wall,
and keep its hardness in a enough low temperature condition as a mechanical guard, during a whole mission before re-entry
(It must never harm its thermal insulators under it.)
on its thermal insulator.
during its re-entry sequence, it is in a very very high temperature condition,
a sprayed stuff will vapor and vanish
(at this time, its guardian role will be end).
a belly of NASA's space shuttle with no damage insulators will appear,
and this is the first time of its mission to show its very belly.
(I think its insulators will take its role well,
before, during and after vaporing of that covering stuff.
If something fly to its insulators,
in the most fatal sequence of its mission,
that is, the highest temperature condition,
it will have vapored before reaching its belly.
So I think its insulators will be guarded
and take its role as a thermal insulator enough
to the end of that sequence and its mission.)
But I feel bad if shuttles will spread something bad for our Earth environment high in the air
for every time of its re-entry.
I want that guard stuff will be good for our Earth environment.
(I think that we have many candidates,
because we can allow it to vapor in that high temperature condition.)
I thought like above, so I made this article.

Will it come true, or not?
An important point for making true is
if insulators have no damage or not,
when something flys to shuttles and hits, I think.
So my heart of this article is "I find one of candidate ideas."
(I think this re-entry sequence is one way of cool re-entries.)
If something bad happens by attaching two materials for mechanical guarding,
some gas cushion will sandwich between them by foam.
