What's the best thermal protection for a dive there and how long is
the flight, that's all I care about.

(Of course Curtis will still say I'm jealous of his lake dive, but at
least I'll meet some friendly Martians and maybe even some friendly
Mermartians. Martians can break bricks just by staring at them)

That would, of course, be considered an altitude dive. Approximately
747 billion feet above sea level (give or take a little for radius of
the earth and orbital variation).

lol

Forgot you guys. Let's round and call it 240 billion metres (see, I
even spelt it correctly).

Right. The spelling is correct (of course it could be discussed which
version is more correct - metre or meter), but the math behind it
completely faulty. Converting and rounding your 747 billion feet gives
only 230 billion, what in the scale gives big difference. BTW I don't
have a clue how did you get the number. AFAIK Mars atmospheric
pressure is roughly 1/100 of those on the Earth sea level and equals
the pressure we have on 32 kilometers (105 thousands feet). It's not
so bad. A little more than 3 and half Mont Everests.

Okay, I did the quick math in my head. I deal with both "imperial"
(or WTF) and SI regularly and independently, so I just know that "this
is a metre" and "this is a foot" and don't try for the 3.3 ft /meter
conversion.

The number is a rough calculation from the MSL of Earth to the mean
surface level of Mars at closest approach. It kind of ignores the
diatmeters of the planets, but simple rounding fixed that problem.
