Re: CHANGING VIEWS BLOG TO THE MOON

Another Idea why not make a larger Tank and also booster Rockets it
would not be that big of a problem I would think.

Wait a minute here... NASA did participate in such an exercise a number
of years ago. When there was a huge asteroid headed for the earth, NASA
officially worked with Hollywood and allowed Hollywood's more advanced
space equipment and crews to launch from KSC to save the earth. The
Hollywood shuttles stopped at the Mir station (docking through the side
entry hatches, pretty neat :-) for refueling and then did a sling shot
around the moon to catch up with the asteroid. It was then that Bruce
Willis and Ben Aflek saved the Earth.

Since we all know that NASA's PAO would not have allowed its facilities
be used to make an impossible or dangerous endeavour, one must assume
that before NASA approved this joint venture with Hollywood, it had done
all the safety and feasability studies to ensure Hollywood's plans were
realistic.

(BTW, i have it on good authority that Bruce Willis survived and is
safely back on earth, but he has since divorced  Demi More).

That's even leaving aside the TPS issues.

Ok, seriously:

Leaving asside fuel issues here. Falling back from the Moon, could a
shuttle have enough manoeuvrability with thrusters/OMS to precicely put
itself in a path that would just hit upper atmosphere and have it enter
an elliptical orbit ? At every perigee, it would hit atmosphere a bit to
slow it down further until its energy level were low enough for the
tiles to shield the shuttle ?

This way, the shuttle would experience multiple heating events, but non
would be too hot for tiles to widthstand and with time for tiles to cool
down between each pass through atmosphere.

Is this concept realistically possible, or would it be considered too
risky because the slightest error would cause the vehicle to make a full
re-eentry at the wrong angle and with way too much energy ?

(replace "Shuttle" with other vehicles, am interested more in the
concept than with a specific vehicle).
