In a presentation on the F-1 engine Rocketdyne proposed three configurations: 1. This was your basic Saturn V. It would lift 260,000 pounds to LEO. 2. This was S-1C and a S-IVB stage and would lift 150,000 pounds to LEO (135,000 with an engine out capability). 3. A S-1C with a S-II on top. This would lift 235,000 pounds to LEO (186,000 with an engine out). Like ALS a family of launchers could be made from Saturn stages. Put in a HL Delta or Titan V and we could lift anything from 1,000 pounds to a quater million pounds. >Unfortunately, if memory serves me, all the smarts of this rocket are in >the third stage.

You are highly unlikely to ever find anything about the scientific and engineering information or the construction of the prototype in the open literature. Even our unclassified briefing last year was embedded in a classified document. Budget concerns, etc, are probably easier to come by. I for one am very interested, and can't seem to find enough about it in magazines, etc. I bet a lot of others are interested too.

This contains Uranus images, including the all images in the browse format (200 x 200). I suggest that you get browse images first and then record the names of the images that you would like to retrieve in full size. Not all full size images are on this disc. Each of these two discs contains browse images for about 2 other discs. The second disc that is on-line is Volume 12 of the Voyagers series and contains Neptune data, again including browse-sized images. Technical, machine readable descriptions of the discs may be found in the file called voldesc.sfd on each disc. And I would like to reiterate my earlier request that if you do use this data in any report, publication, or formal presentation, that you make the following credits: For Voyager data: Dr. Bradford A. Smith For Magellan data: Dr. Gordon H.

Voyager almost missed the window (which only opens about once in about 200 years) because of delays for launches. I'd give you more examples but I don't feel like it. The point that hardly needs a reference is that delays mean there is a waiting line for launches. There's tons (literally) of market for space on such a launcher. You could even do something hare-brained, like LAUNCH TWO AT ONCE!

REDMOND) Subject: HEADLINE NEWS/TV SKED 4/29/91 Message-ID: Sender: daemon@news.arc.nasa.gov (The devil himself) Organization: NASA Ames Research Center, Moffett Field, CA Date: Mon, 29 Apr 91 09:00 PDT Approved: telemail Headline News Internal Communications Branch (P-2) NASA Headquarters Monday, April 29, 1991 Audio Service: 202 / 755-1788 This is NASA Headline News for Monday, April 29, 1991 . . . Following yesterday's 7:33 am launch, Discovery is presently in a 160 statute mile orbit and all orbiter systems are working fine. There is a problem, however, with the twin data tape recorders used with three of the Air Force's secondary payload bay experiments. The recorders are used to store experiment data gathered by the Uniformly Redundant Array, the Horizon Ultraviolet Program and the Quadrupole Ion-Neutral Mass Spectrometer. These instruments can still be used in real time to gather background horizon, payload bay contamination and astrophysical X-ray source data. Both the ground team and the flight crew are still troubleshooting the recorder problem. But at this morning's change-of-shift flight director briefing, the Air Force program officer for these experiments said even if the recorders couldn't be fixed, the mission would still meet more than 80 percent of the scientific objectives for those experiments. The Cryogenic Infrared Radiance instrument, one of the two primary JDepartment of Defense payloads on the mission, last night obtained auroral emission data which was characterized by the investigators as being quite exceptional. Aurora activity has been very strong so far and is predicted to continue strong for the next few days. Discovery's launch from Kennedy Space Center's Launch Pad 39-A was delayed about 30 minutes yesterday while launch controllers assessed any potential effects of a data recorder which had inadvertently gone into record mode. The assessment showed no potential impact from the anomaly and launch proceeded accordingly. Of the seven crewmembers aboard, five of them are first timers. Commander Mike Coats and mission specialist Guy Bluford are the space veterans, each with two previous flights. The crew have split into their Red and Blue teams, with pilot Blaine Hammond and mission specialists Lacy Veach and Richard Hieb on the Blue Team, and mission specialists Bluford, Greg Harbaugh and Don McMonagle on the Red Team. Coats is free to adjust his schedule as the mission requirements merit. The general breakdown of the shift schedule has the Blue Team active during the day, with the Red Team performing the overnight activities. Both teams are up together in the pre-dawn morning hours and again during the early evening. Most of the complicated maneuvers set for the orbiter and its payloads are scheduled for these early morning and early evening periods. * * * * * * * * * * * * * * * * Administrator Richard Truly Friday named Dr. J. Stuart Fordyce as Deputy Director of the Lewis Research Center. The appointment was effective Friday. Dr. Fordyce had been the Director of Aerospace Technology since 1984. Previously he has also been chief of the Lewis Space Power Technology Division and chief of the Electrochemistry Branch. His doctorate degree in physical chemistry is from the Massachusetts Institute of Technology. * * * * * * * * * * * * * * * * The philanthropic W. M. Keck Foundation announced Friday that it would provide up to $74.6 million dollars to begin the construction of a second segmented-mirror telescope adjacent to the present Keck telescope atop Hawaii's Mauna Kea volcano. The California Institute of Technology and the University of California will manage the second telescope, as they now manage the first. The new Keck will be built 85 meters from the present facility. Keck I and II will be able to work in tandem providing an optical and infrared interferometer 85-meters in diameter. Officials from the Foundation, CalTech and Cal indicated that construction on the new telescope is scheduled to begin early in 1992, just about the time Keck I becomes fully operational. Keck I is presently in the process of optical alignment. Keck II is expected to begin operations in 1996. Here's the broadcast schedule for Public Affairs events on NASA Select TV.
