I'm positive this has been mentioned at some point, and I know its late for suggestions, but...

The levels of radiation around the larger planets are assumably very unhealthy for astronauts, but the DG-III can
send them through it again and again and they shall always be fine. Perhaps an extra readout somewhere on the
board should be a geiger counter to measure radiation. It would notify of unsafe dosages which the pilot would have
to raise the craft out of.

I don't know how you could have it so the crew dies from exposure, but I suppose it could be possible. Maybe just for
now you could give certain orbiting altitudes around certain planets deadly radiation levels. A bit of research might be
needed to make it accurate though.

Mmmmmmmmmmmmmmmm. This is something which hasn't been suggested before. :wonder:
I wonder what Dan would think of this.

It's a good idea, but I doubt Orbiter supplies any kind of data about radiation..

Which means Dan would have to also add some sort of table of radiation levels/distance for every planet. And I'm not
sure the radiations that is causing problems is X-rays alone.. Jupiter for example is a planet with a pretty nasty
character, so we are probably talking everything from gamma to microwaves.... Then there are the strong magnetic
fields.. consequently, I believe this would also create electrical currents.. This would create all kinds of static charges.
Probably a whole lot more too... Most of it isn't designed to increase health :) Which in effect all makes it a lot more
difficult to code...

Just imagine DG-III is made of Quad Titanium or something indestructable :)

Is that why it bounces when it hits a planetary body? :)

Ah, the pieces of the puzzle come together.

What orbits are dangerous around the earth? I remember hearing about the Van Allen belts creating trouble for the
Apollo astronauts, which provided the conspiracy theorists more information to discredit the program. Although I
believe we went to the moon, where are these no-go spots?

It's nasty, but I think the Van Allen belts are more or less what Earth has to offer :) Now Jupiter here:

The Van Allen belts aren't bad just for a pass through, and we have them fairly well mapped.  I had a good map link for them
but it's gone astray. When I find it, I'll post it.  In the meantime try googling. I believe the Apollo astronauts received a
dosage equivalent to one chest xray on their missions.

For the other planets we do not have complete maps that have been released.  It takes an orbiter to do this, not a fly-by. To
date we have only sent orbiters to Venus, Mars, Jupiter and Saturn. I know of no mapping data of Venus by Magellan, Mars is
benign, having a very small magnetic field. Galileo should have provided good data on Jupiter but I don't know if any maps
have been released yet and, of cours, Cassini has just begun probing the Saturnian environment

Of course, we need good maps to derive good data tables to include in Orbiter. Until then we would have to SWAG it
(Scientific Wild Ass Guess).

Doc:

SWAG is an old military acronym (a word made up from the beginning letters of the words of a longer phrase).

Other common example:

SNAFU  (Situation Normal:  All F***ed Up)
FUBAR  (F***ed Up Beyond All Repair)

and many, many others.  Usually humourous and to the point.

hehe, I know I just thought the expression was fun :)

BTW, what does SNAG mean? IT is usually used to express that something went wrong or that someone f****ed up
something :) Is this also an acronym or an actual word?

Snagging is catching something. For instance, I could snag lunch really quick (mmm, hungry) But it also refers to
something like a thorn snagging on your clothes and tearing them. So, when you hit a snag, you catch on something
that holds you back or harms your plan.

Close, and is used that way.

 I think the origin comes from the logging industry, when they used to float trees down rivers to the sawmills.  On a bend in
the river, logs would get caught up with each other or entangled in the roots of other trees.

And we're getting off topic again.
