I have heard much discussion of a sci.astro list, and I am sure I would find it very interesting. So, I have a question on how I might subscribe to the list. I currently only have access to a Bitnet site (all my mail to and from sci.space gets packaged up on a bitnet site and sent through whatever network is the home for sci.space, as I understand it..) Does a similar situation exist for sci.astro, and if not, is there any way I can subscribe to the distribution from Bitnet at all? Thanks for your replies.

The classic example of this was the loss of the XB-70 aircraft. The B-70 used a special seat with clamshell doors that enclosed the pilot to survive ejection at altitudes up to 80000 feet and speeds up to Mach 3. During this sequence Al White ejected, but not before the clamshell doors closed on his shoulder dislocating it. It was necessary for him to pull his arm inside the doors for the remaining sequencing of the seat to occur. Carl Cross never did eject from the aircraft and died in the accident. >Back to the S-3 for a moment: the canopy does not jettison prior to >ejection (it is too big)--there is a breaker bar mounted above the crewman's >head and ejection is *through* the canopy. Ouch. Well, it sounds like an >"ouch," anyway--I've talked to guys who've done it and they say, essentially: >"Trust me, you don't notice--or care." The British have a quaint way of getting through the canopys on their aircraft (and the aircraft that we get from them, the AV-8 Harrier and the T-45 Goshawk). They use a shaped charge embedded in the canopy above the pilots head. When the ejection sequence is initiated the shaped charge blows and destroys the canopy, after which the seat and pilot go right through ;-). -- Albion H.

Whether it would have been worth it or not is, I think, debatable. New food and clothes would have to have been taken to the station. We had no more available Saturn IB's for launch, and modifying the Skylab to dock with the Shuttle would have probably been very difficult in terms of hardware costs, among other things. (Anyone know if the Shuttle would have had any trouble clearing the Apollo Telescope Mount solar panels?) All of the previous Salyut's have been de-orbited (most of them intentionally :), so I assume the same will be done with Salyut 7. -- ---------------------------------- jabishop@uokmax.ecn.uoknor.edu "I'm President of the United States and I'm NOT going to eat any more broccoli!" -- George Bush ------------------------------ Date: 9 Apr 90 22:32:48 GMT From: trident.arc.nasa.gov!yee@ames.arc.nasa.gov (Peter E.

Engineers and technicians have completed their careful checkout of the Hubble Space Telescope at Kennedy Space Center's Launch Pad 39-B complex. The test took longer than originally planned, but NASA officials wanted to be very sure that all was well with the orbiter's unique payload. With telescope testing completed, the pad will be closed today to all but necessary personnel as ordnance is installed aboard the STS-31 space shuttle. The launch schedule calls for a lift-off Tuesday, April 10, at 8:47 a.m., EDT. Landing at Edwards Air Force Base is scheduled for Sunday, April 15, at 10:02 a.m. * * At KSC's Orbiter Processing Facility, a fuel cell aboard the orbiter Atlantis has been damaged during a test operation. The unit will be removed from the orbiter and replaced. There will be no impact to the next Atlantis mission in July. Atlantis recently completed a classified mission in mid-March for the Defense Department. * * The launch of the Pegasus winged orbital booster is scheduled for today at about 3:07 p.m., EDT. NASA Select Television will begin coverage of the mission at 1:45 p.m. Foul weather off the southern California coast forced a postponement of the launch attempt yesterday. Weather is more favorable today. * * The Galileo spacecraft continues to operate without incident. It's almost 128 million miles from Earth and about 75 miles from the Sun. A week ago the Deep Space Network tracking station at Canberra, Australia, experienced a massive power failure and tracking operations were shut down for about 5 hours. Despite the ground power loss, Galileo successfully executed a Sun pointing turn. The maneuver was verified after power was restored to the tracking system. Next week, Galileo will do a four-day trajectory-correction maneuver...the first step in preparing the spacecraft for the initial Earth gravity-assist flyby on December 8. *************************** ----------------------------------------------------------------- Here's the broadcast schedule for Public Affairs events on NASA Select TV.

Shows what a bunch of ivory-tower dolts run one of the premier science programs in the US. These guys have been locked away in the labs so long that they seem to have fogotten that their programs are paid for by the US taxpayers. Their planetary probes run on US taxpayer dollars, and if they ever hope to get more money for more and bigger probes, then they are going to have to realize that they cannot be so disociated from reality. Without the support of the taxpaying public, JPL will not have much cash to play with. Why can't they release just a few images for distrubution to the net? They give some images away to press crews and such, so distribution to usenet should not be a real problem at all. Alienating the type of people who strongly support space research efforts is *not* the way for JPL to proceed. Like that guy said in "The Right Stuff": No Bucks, No Buck Rogers! >This really boggles my mind. I guess I'm not surprised now that JPL couldn't >get money to send a probe to Halley, and it's hard to feel very sorry for them. Maybe if we write letters to our Congress critters? Nah, they probably are too interested only in things that mean "re-election"! Besides, the idea of your average Congress screw-up trying to deal with "advanced concepts" like distribution of digitized images is probably just too much to ask..... BTW, we have some people from JPL that post to this newsgroup.....maybe they should show this thread to the head-honcho. Maybe this would result in at least an explantion of why JPL will not allow for the distribution of the digitized images.
