Although I don't know if it was due to Schirra that there were manual systems for Cooper to use, I think that flight would have been lost without them. There was a near total electrical failure, according to Cooper (he said he had a radio, and could control his attitude by mechanical linkages opening valves). > >Also there were 7 mercury astronauts, but i believe only >6 flights. I think slayton didn't fly. Why was his flight cancelled? He was diagnosed with a heart murmur and removed from flight status (he would have flown after Glenn, on the flight Carpenter made). After spending over a decade in charge of the astronaut office, he managed to fly in 1975 on the last Apollo to fly, on the Apollo-Soyuz test project. -- Chris Jones clj@ksr.com ------------------------------ Date: Wed, 19 May 1993 21:43:49 GMT From: "Andrew W.

The boundaries of individual countries >stop in the upper atmosphere so what happens??? Aside from the legal aspects of murder in space, I can't help but wonder what kind of havoc such a crisis would have. For example, assuming that the murderer was the only one left aboard one of the space shuttles, how are you going to get him/her to land the thing?! I realize that eventually all of the oxygen, food, water, etc. would be used up, but the murderer might also decide that going back to earth and facing an arrest not to mention the electric chair would be just as bad or worse than dying in space. There is also the possibility that anyone who murders someone in space will be crazed and desperate enough to hold the other astronauts hostage: what then? I guess the basic question I'm asking is whether or not NASA or any of the other space agencies have certain procedures to be followed in the event of such an emergency.

Before and during the flight, Armstrong had been EXPECTED to make some grand statement, and he made sure the viewing audience got their money's worth. I even remembering the local paper running a contest to guess what those first words would be. With all the speculation on what he might say, I recall everyone being generally pleased that the statement was properly grand and properly memorable. Of course, my memory may be faulty :-).

I would "assert" that for a wide variety of reasons, that does not seem very likely to be the type of output provided by space based platforms such as the Advanced KH-11 series... These satellites are designed to give *very* high resolution images, and I seriously doubt their imaging capability approaches full motion video. For one thing at the resolutions involved the data downlink requirements would be horrendous, combined with the fact that 2-3 of these birds are typically on orbit... AND you also have two Lacrosse RADAR imaging satellites sharing the same communicaitons paths, generating daily a tremendous amount of SAR data. >[Note that I am *not* asserting the fact of the existence of such a >system with a 30fps or similar frame rate.

As for aircraft... SR-71 Blackbirds did not have a real time capability, for one thing they used primarily FILM cameras for their photorecon work. The U-2/TR-1 is pretty much the same, although there were at least some tests done with a TR-1 carrying a live satellite uplink package. However, the still-classified TR-3A is supposed to be capable of delivering real-time tactical reconnaissance data to battlefield commanders... { Dean Adams } ------------------------------ Date: Thu, 20 May 1993 07:21:07 GMT From: Rob Geraghty Subject: Soyuz and Shuttle Comparisons Newsgroups: sci.space aws@iti.org (Allen W.

Energia was capable of lifting *more* than Shuttle. Aside from that, what happened to the Soviet copy of the Shuttle? Couldn't that be used in the same way as shuttle itself? (Note my emphasis above - Soyuz is *not* the Russian heavy lift vehicle) I suspect that the answers to my questions consist mostly of "they can't afford to operate them"...

Actually, a telescope can't track fast enough to follow an object in a Low Earth orbit: It would just be an annoying blur. But the Soviets used to get alot of public relations milage out of such a dim, hard to spot object: Whenever they had "guests" for another country on their space station, they always made sure the station could be seen from the guest's home nation. They then pointed out the point of light and reminded people that one of their countrymen was on it... I could imagine _some_ similar PR value in a unmanned satellite: What if AT&T could show you the satellite they put on orbit and which you use every time you make a long-distance call?

You know, I once was in a popular Honolulu city park flying a kite in the evening twilight (dark enough that some stars were visible, prime satellite time). There were fair numbers of people around all over the place; it was a very pleasant Sunday evening. Well I was looking up because I was watching my kite "flying among the stars". And then this incredibly _bright_ point of light appeared right next to my kite and expanded out into a ~30 degree wide glowing white donut in the sky over the next minute. WOW! It was bright enough to cast a slight shadow! AMAZING! I yelled, of course, "wow, look up! What's that!". (I found out later it was an unannounced military star-wars test launched from Kaua`i.) After it was over I ran around and asked the other people in the park what they thought it was... NONE of them saw it, except for _one_ person who looked up _because of my yelling_. I realized then that most people DON'T LOOK UP. Even something that big and bright wasn't enough to attract their attention... people aren't expecting to see anything interesting in the sky. If that's true, which I'm pretty sure it is, I don't think we have much to fear from "space advertising". Except for maybe the first time when (a few) people would be excited enough to go out and look at _just the right time_, it would be a complete waste of money _for advertisers_! They aren't going to pay for it more than once, because the average person NEVER LOOKS UP! /\ /\ /\/\/\/\/\/\/\.-.-.-.-.......___________ / \ / \ /Hawaii Institute of Geophysics, Honolulu\/\/\.-.-....__ ___/ \/ \/Joe Dellinger, Internet: joe@montebello.soest.hawaii.edu\/\.-.__ ____________________________________________________ Objectivity is not an unobtainable emptying of mind | but a willingness to abandon a set of preferences |----> Stephen J.
