now please explain what a 'dead-in' technology is


One with a limited future as a base for other actives.


OK In British English that would be dead-end


American English as well, some times I don't proof read so well.

and why satellites deserve that description,
even if only in relative terms.


Out side a spurt in the first decade or so of space flight there has
been precious little expansion of human activities dependent on it.


You have to be kidding.

If you turn on the TV news the pictures from abroad came via satellite

If you make an international call the chances are that goes via satellite

When you listen to the weather report that are based in large part
on satellite data


All having their origins in the 60s.

The aircraft you fly on use GPS nav systems


Which replaced ground based locating systems. Granted it
covers more area more cheaply.

Most space activities are either of scientific curiosity in the main,
or a cheaper base for doing something that could be done within
the atmosphere.


Try doing any of the above using aircraft.


Submarine cables could cover the first two and have been
around longer than even airplanes.
Additional weather flights and ground stations the third.
And if you can cover the earth with cell phone towers, you
can add location beacons to'em. OK, GPS is about the only
innovative use for space in decades.

I am old enough to recall the time you had to
book transatlantic calls hours in advance and
when Hurricanes could strike major cities with
only a couple of hours notice and when news
footage from across the ocean relied on film
being flown across them.


Fixable terrestrially with more expenditures. Yes,
space systems are a cheaper platform for doing some things.

Winged flight in the atmosphere fundamentally exceeds other means
of transport in terms of speed and is a necessary base for many
kinds of commerce, recreational activities/opportunities, war fighting,
cultural connections and logistical communication.


Most passenger journeys are made by ground transportation
which now heavily depends on satellite technology for
the information travellers need from the weather forecast through
GPS in car nav systems and of course the radio news


Oh come on now, you aren't claiming that anyone is dependent
on GPS and satellite weather to drive some where? Most terrestrial
passenger journeys being of a rather local nature.
Of those journeys not local in nature, call it over a day's ride via
surface transport or transoceanic, the aircraft is the preferred method.
The only time space flight is the preferred method of travel is when
the destination is different stellar body; gee, when was the last time
anybody made that trip, 30+ years ago?
You would be better off arguing the easy of navigation for private
boats to prove the transformational worth of GPS.

People, as a general group as opposed to an extremely select few,
even fifty years on do not fly in space and there is little indication
this will change in another fifty years. Fifty years after the Wright
brothers' flight air travel was quite accessible to the average
person in our societies and was in the process of becoming the
preferred form in many cases; a trend that will likely continue
well into the third fifty years.

Compared to flight through the air, flight through space is unimportant.
I concede this could change, just not in the foreseeable future.


Which has zip to do with the vital role satellite technology
plays in our every day life.


Agreed, but it does have a lot to do with which is more likely to
be celebrated on its anniversary. And even more to do with my
original statement.

they took me back in time and the nsa or japan wired my head and now they know the idea came from me so if your back in time and wounder what happen they change tim liverance history for good.
