bogus talking points since *opportunity has operated for 9 years and

Which is a great description of your position; "bogus talking points".

ISS originally had 3 astronauts when it was brand new, and it took
nearly all of those 3 just to do maintence. Obviously a human rated
station will need lots more service and be far more complex than a
rover.

Because it was UNDER CONSTRUCTION. *As I said earlier, comparing that
to a Mars mission is comparing apples to aardvarks.

Fred your slipping........

Not hardly....

first fred talks of the stations age, now its under construction ......

Bobbert obviously can't even follow his own ramblings. *ISS *is* old..
When it "originally had 3 astronauts when it was brand new" it was
still under construction.

opportunity has traveled 22 miles in 9 years, without any on site
service.

And let's look at this record that Bobbert is touting for his
favourite toaster. *That 22 miles in 9 years amounts to a rate of
advance of a whopping .00028 miles per hour. *A man in a Mars car
could more thoroughly explore that 22 miles in a single day than
Bobbert's toaster has managed in 9 years. *That's a 3285:1 advantage
to man. *NOW run your cost comparisons! *Assume men will have 6 months
on the ground and figure out how many rovers for how many years you
would need to even come close to what they could do.

humans will reqiuire systems under constant repairs and rebuilding.

Why is that? *We can build rovers that require no maintenance for 9
years but the instant people are around everything breaks down all the
time? *You honestly believe that? *REALLY???

Even if you assume a preposterous maintenance burden, there is STILL
that 3285:1 advantage to man. *On a 6 man mission, you could dedicate
2/3 of the available hours to maintenance and STILL get that advantage
over a toaster.

fred maybe the earths nations should cut miitary spending to zero, and
use a fraction of the saved money for space exploration. whats your
thoughts on this

Other than that it's a stupidly unrealistic question, you mean? *If it
was possible I think it would be a wonderful thing. *However, since it
isn't, I think we need to be by far the biggest dog in the forest. *If
we're not, we'll likely get new rulers who won't let idiots like you
bleat about everything. *Then what would you do?

ahh while opportunity took 9 years to travel 9 miles it wasnt just
looking at things, it was doing real science, grinding and sampling
rocks as it went along.

no doubt a rover could be built to travel the same route fast but then
you lose all the detail work.

Unless you had people in it who could look and see interesting things
and stop and knock of a sample.



if you believe its easy to build human rated equiptement that requires
near no service you should be working for nasa designing ISS systems.

I could be, but I don't want to move to Huntsville.



The ONLY human rated system in existence today require constant
maintence.'

Mostly because it's old and wasn't designed to not require it.



While opportunity and the other rovers require no on site maintence at
all, over many years.

You might want to look up the design lifetimes of those things.



While it would be great to have humans on mars for hopefully *more
than flags and footprints......

Since they'll be there 6 months, I suspect they'll be doing more than
that.



Theres no money, theres little or no public support, theres no real
political support, we lack some necessary equiptement, like nuclear
booster to cut travel time, like radiation protection for crews in
deep space....

Nuclear engines aren't required, as you've had repeatedly explained to
you. *As for radiation protection for crews, we invented WATER a long
time ago. *Again, you've had all this explained to you. *You really
need to pull your head out of your ass and stop being so adamantinely
ignorant if you expect people to take anything you say at all
seriously.



basically we lack the basic building blocks to send humans While we
definetely have a great start on robotic planetary exploration....

Basically, you're an ignorant lying ****bag. *There's less support for
your toasters than there is for a manned mission. *If people aren't
going, save the money and stop sending toasters.

your just a plain idiot.

while chemical propulsion could be used, travel time will be around 6
months each way and mars ground time near 2 years, or thereabouts. or
at best a week, cant do much in a week.

making a total travel time of nearly 3 years, if the crew stays 1.5 to
2 years on ground

crews gone that long, so far from earth are going to have big problems
with both physical and mental condition.. whats the longest time in
space up till now? around a year?
