It's not exactly in the same speed class as B-70 or FB-111, but I saw an article several years ago (in AW&ST?) about an idea for a small propane+LOX space plane with a large drop tank, to be air launched from the back of a 747. Not just an ordinary 747. This one had an SSME mounted in the tail to get a healthy climb rate at a steep angle. -- David R.

The word, in case you've forgotten, is "digital". Glossy photos >we *know* NASA will release. >-- I have access to a 300 dpi digital color scanner and have made numerous GIF images of Voyager photos from magazines and books. The resolution is 640x480x256; typical file size is 200K. While obviously not "raw science data" I suppose they might be interesting to manipulate digitally. They typically come out better than the frame-grabbed images I've seen. I'd like to offer them to anyone interested, but having no access to an ftp site, I can't put them in a place where they can conveniently be retrieved. If anyone with ftp access would volunteer, I could mail them the floppies (what a network!) and they could upload them to the ftp site. Also, I would like to know if there is a good source for Voyager photographs. Magazine photos digitize on my scanner pretty well if they are 1/2 page or larger, but with smaller photos I start seeing evidence of the four-color printing process when the image is blown up. I'd love to get 8x11 or larger glossies.

They wouldn't be evenly distributed, would they? I'd expect clustering in launch facilties [Mid-Florida, Northern South America, a couple of sites in Asia] just to avoid needless duplication of launch resources. Mind you, most launch sites are as close to the equator as convinient, and the ozone munching processes seem to run with maximum efficiency at the poles [Of course, CFCs seem to got the problem of getting to the poles solved, and they get used mostly in temperate countries]. If there *is* an upper limit to tolerable launch rates, it will be interesting to see how launches get allocated. Is there an obvious international authority for this kind of thing [and does anyone ever listen to it]?

Pegasus might need some redesign for this, however, given the thinner air and greater aerodynamic heating. It's really a pity that XB-70 #2 crashed, since it had the definitive control systems and generally solved some of #1's problems. (#2's crash was one of the things that killed proposals for an XB-70-launched successor to the X-15.) >...In the 25 years since the Valkyrie came out, has there been another >plane that was better for launching something like the Pegasus into orbit? >Does anything come close to the Valkyrie? In a word, no. Highly-supersonic flight has largely gone out of fashion for military purposes. (This was one of the reasons the B-70 died.) An SR-71 just might be capable of it, although its career as a drone launcher was cut short by a nasty separation accident that wrote off both drone and SR-71. That only marginally counts, since the SR-71 dates back to the same era as the XB-70. (Say, I wonder what the payload of a Foxbat is...! :-)) >What can the B-1 and B-2 do? The B-1A was supersonic, but not greatly so; I think the B-1B abandoned supersonic capability when its engine inlets were redesigned to reduce radar signature. The B-2 is subsonic. >How soon will there be a hyrogen powered scram-jet plane? Apart from the Aerospace Plane, whose future is uncertain, West Germany's Saenger project -- aimed at a reusable space launcher with a hypersonic jet as the first stage -- is the only serious effort even talking about such a thing. It has no other civilian applications, and the military prefers flying low and slow nowadays. -- With features like this, | Henry Spencer at U of Toronto Zoology who needs bugs? | uunet!attcan!utzoo!henry henry@zoo.toronto.edu ------------------------------ Date: 11 Apr 90 18:09:05 GMT From: tellab5!kleiser@uunet.uu.net (Steve Kleiser) Subject: Re: HST Image Status for 04/01/90 (Forwarded) >Well, I can understand a year of exclusive use of the raw data for the >principal researchers.

But these guys often spend millions of tax dollars to get that data, & WE deserve something for that. A year isn't long to wait, but in my opinion the data should be released to the public after a *reasonable* period, & getting the data onto the net sounds like a very rapid means of distributing it. What sort of effective action can netreaders take to achieve this goal? Who are the right people to write to? Lets avoid wasted effort, such as flooding people with mail who couldn't change policy even if they wanted to. Any ideas?

Second: I realize this may not be the sort of thing for these news groups, but at the moment I have no better recourse, so send me all the flames you want. I am a graduate student at Rutgers University and will be receiving my MS in Electrical Engineering in May. My ultimate desire is to be Mission Specialist for NASA. I have noticed that most Mission Specialists have their Ph.D.s, some in EE. I am considering continuing for my PhD, but wonder if it is really necessary and am worried that it may leave me over-qualified for the things I like to do, in case I wash out of Mission Specialist school. Let me give you a brief resume: BSEE 1986, Rutgers University. GPA: 3.91 (4.0 = A). June 1986 - June 1988: Western Union Satellite Control Facility (WESTAR) wrote real-time telemetry and command software for HS-376 communications satellites. Sept. 1988 - Present: Persued full-time graduate study, Rutgers University. Graduate GPA: 3.75. Full time teaching assistant. Program in Digital Signal Processing, Computer Engineering and Software Engineering. Additionally, I am fairly well versed in programming in C and C++, have worked under Unix, MS-DOS, RSX-11M+ operating systems, and have been the System Administrator for five Sun386i workstations for the past year. I suppose my questions are: 1) Is a PhD a requirement for being a Mission Specialist? 2) What are my chances of actually becoming a Mission Specialist? 3) I have been told that a private pilot's license or a ham radio license would be helpful. True? 4) How about experience in the Air Force Reserve? 5) Anybody have a job for me? :-) (just kidding). I suppose that if you think this is of general interest, you could reply on the net, else send e-mail to: tandre@fourier.rutgers.edu or andre@elbereth.rutgers.edu Thanks very much for your attention!

(rest deleted) I would like to add one other thought. Why not go direct to the people that will actually be running the Hubble Science Program? That is the Space Telescope Science Institute, c/o Johns Hopkins University, Baltimore, Maryland. NASA has many programms to manage, the people in Baltimore are dedicated to managing just the HST. just the HST ------------------------------ End of SPACE Digest V11 #251 *******************
