Looking at what is happening in the Gulf, as well as other historical trends, it seems that we are taking care of the Japanese national defense (not to mention many of their technical R&D costs), leaving them free to spend money on space exploration.

All STARCALS (star calibrations) and DESATS (desaturations) since yesterday were successful. Late today, the mapping command sequence M1030 will be sent to the spacecraft, along with the associated parameter files. During the 4-day mapping sequence now being executed, the radar swath width at the North Pole was increased to 40 km to facilitate studies of the pole location by the RAND Corporation. The temperature of spacecraft Battery #1 has gone above the alarm limit of 20 degrees Celsius several times in the last few days. This was expected due to the changing sun angle on the orbit and the return to full mapping passes. Spacecraft controllers are discussing options for temperature control of the battery. ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@mars.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |___ M/S 301-355 | It's 10PM, do you know /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | where your spacecraft is? |_____|/ |_|/ |_____|/ | We do! ------------------------------ Date: 29 Jan 91 20:58:17 GMT From: usc!cs.utexas.edu!news-server.csri.toronto.edu!utgpu!utzoo!henry@apple.com (Henry Spencer) Subject: Re: Why man rate?

Titan II was used for Gemini, of course, but one might rule that evidence out of order on the grounds that II didn't use SRBs. However, there were firm plans to man-rate a variant of Titan III, specifically the IIIM, for launch of MOL (essentially a small military space station) with a Gemini on top. -- If the Space Shuttle was the answer, | Henry Spencer at U of Toronto Zoology what was the question? | henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: 28 Jan 91 11:55:41 GMT From: van-bc!rsoft!mindlink!a752@ucbvax.Berkeley.EDU (Bruce Dunn) Subject: Re: Request for Feedback on Proposed Lunar Analog Robotics C > smith@sndpit.enet.dec.com writes: > > > In article <9972@orca.wv.tek.com>, doughe@bamboo.WV.TEK.COM (Douglas E > Helbling) writes... > > b) Size - the current limit on physical size for the "unextended > unit" > > is two feet square.

If so, who uses it and >for what purposes? When I first heard of such things, it was in connection with space launch technology. One possible launch system would use a variation on a magnetic coil gun, or rail gun, or some such thing, mounted on the side of a mountain near the equator. It would shoot a payload at about 1000 G initial acceleration into earth orbit. This is great for payloads that can take that, but you or I can't, since the front of your chest would collapse right into your lungs under that much gravity, and you'd wind up looking generally like high-tech road kill. The idea they had was to use liquid breathing, with some complicated solution, to fill your lungs and breathing spaces, then fill your sinuses and middle ears with some neutral solution and put you inside a tank of water, such that everything would be at the same density. Then they could shoot you out of their cannon without it bothering you. I don't know how far this idea ever got developed (maybe if I cross-post to sci.space Henry Spencer or some other kind soul might respond) but evidently at some point somebody saw a second application of such technology to deep-sea diving and the liquid-breathing diving apparatus in _The Abyss_ resulted. I'm actually not sure either whether this technology is actually applicable to diving, since the whole idea of not crushing your lungs is to be breathing air/gas mixture at the same pressure as that around you, or whether it might be possible that beyond a certain depth a gaseous mixture gets too dense to breathe and the liquid might provide a better oxygen-in CO2-out mechanism. Just for you sci.space readers, the same issues would apply to any attempt to build a spacesuit to visit Jupiter or anywhere with a thick atmosphere. I heard via my brother that apparently a human volunteer had breathed this stuff successfully, but I'll leave that classified under Urban Legend unless and until anyone can confirm that. -- Anthony DeBoer - NAUI #Z8800 adeboer@gjetor.geac.com Programmer, Geac J&E Systems Ltd. uunet!jtsv16!geac!gjetor!adeboer Toronto, Ontario, Canada #include ------------------------------ Date: 29 Jan 91 17:46:06 GMT From: usc!elroy.jpl.nasa.gov!jato!mars.jpl.nasa.gov!baalke@ucsd.edu (Ron Baalke) Subject: Galileo Update - 01/29/91 GALILEO STATUS REPORT January 29, 1991 Today, the planned sun acquisition activity was successfully completed with the Galileo spacecraft.

This Standard has been developed by a Technical Panel chaired by Dr. Robert J. Hanisch (Space Telescope Science Institute). It is being developed with the goal of gaining endorsement by the International Astronomical Union as the formal standard for FITS. The form of the standard is not final and should not be considered to supersede the existing FITS documentation. The NSDSSO FITS Standard will be a formal codification of existing FITS practices as defined in the four basic papers, the Floating Point Agreement, and in other actions of the international and regional FITS committees. It is not a revision. This purpose of distributing the Draft Standard is to provide for review and to gather comments. The Technical Panel will review and respond to all comments. NSDSSO wishes to have this document reviewed by as broad a representation of the affected community as possible. The FITS Draft Standard may be obtained electronically on either the Space Physics Analysis Network (SPAN) via default DECnet copy commands or the Internet via TCP/IP anonymous FTP commands. The NSSDCA computer is a VMS/VAX 8650; therefore, filenames are case insensitive and disks and subdirectories are indicated as: ANON_DIR:[FITS] for the disk "ANON_DIR" and the directory "FITS". Retrieve the README. file first. It describes the files in the FITS directory, provides more detail on session and retrieval procedures, and explains how to register comments with NSDSSO. NSSDCA is a member of a VMS/VAX cluster, and the other principal node, NSSDCB, can also accept default DECnet and anonymous FTP requests. ========================================================================== Internet (TCP/IP) SPAN (DECnet) ---------------------------------------------------------------------- Name: NSSDCA.GSFC.NASA.GOV NSSDCA Address: 128.183.10.4 6.133 (6277) Name: NSSDCB.GSFC.NASA.GOV NSSDCB Address: 128.183.104.11 6.866 (7010) ---------------------------------------------------------------------- =============================================================================== == default DECnet README. copy via SPAN == =============================================================================== ndadsa $ copy/log nssdca::anon_dir:[fits]readme. * %COPY-S-COPIED, NSSDCA::ANON_DIR:[FITS]README.;1 copied to DISKA":[MEV]README.;2 (1 block) =============================================================================== == Anonymous FTP README. copy via Internet == =============================================================================== ndadsa $ ftp nssdca.gsfc.nasa.gov NDADSA.GSFC.NASA.GOV MultiNet FTP user process 2.2(100) Connection opened (Assuming 8-bit connections) user anonymous cd anon_dir:[fits] get readme.;1 readme. quit amos@SHUM.HUJI.AC.IL (amos shapir) writes: >In the referenced article I wrote: >>In article <1991Jan07.035548.20194@vpnet.chi.il.us> vortex@vpnet.chi.il.us (Jason L.

Because of the uncertainty of the reentry time it is impossible to predict at this point where it will reenter. It is in a 51.6 degree inclination orbit, so it could reenter anywhere between 51.6 N and 51.5 S latitude that is under those orbits on Feb 8-10, in other words, almost anywhere on the planet except north of 51.6 north latitude or south of 51.6 S latitude. --GaryM -- Gary Morris Internet: lescsse!gamorris@menudo.uh.edu Lockheed, Houston, Texas UUCP: lobster!lescsse!gamorris Space Station Freedom Internet: gmorris@nasamail.nasa.gov N5QWC/W5RRR Phone: +1 713 283 5195 ------------------------------ End of SPACE Digest V13 #104 *******************
