Why is he saying this? The only reason I can think of is to imply that it was the Apollo programme that drove the development of computers. I don't think that that was true at all. > The nature of space systems makes them particularly >suited to the study and investigation of our own planetary >processes; it is from space that we have gotten our earliest >warnings of the possible growing crisis of climate and it is only >from space that we will be able to fix upon and understand the >real extent and direction of environmental change. This is even more questionable. The "possible growing crisis of climate" I assume to be the question of the hole in the ozone layer and possible overheating due to increases of CO2. The ozone data were first produced by the British Antarctic Survey station at Halley Bay. A satellite (I don't know which, NOAA??) had reported similar data but this had been rejected as due to faulty sensors. To forstall nationalistic comments, I am not saying this because it was the *British* Antarctic Survey, but because it was on the ground. Similarly, I believe that the best data showing long-term CO2 increases come from the mountain-top observatory in Hawaii (whose name I vaguely know but can't spell :-). I am not saying this to be anti-space, but these seem poor examples to use in support of the current space program. Peter Ilieve peter@memex.co.uk Memex Information Systems Ltd.
