It's gotta be done, to brin the solar sail (which must be outside of the magnetic field to even work, far as i... WAIT! We can face the Ramjet AWAY from the sun when using the sail, and any photons coming from back there intended for the sail can still hit it since they won't be charged! Then, the sail can be inside the field, and it won't have to have some huge rod to get it away. And we can STILL collect hydrogen up front! Okay, anyways, (no more parentheses anymore) does anybody know of a way to retract this solar sail (which must be rigid (but possibly foldable), as it will contain solar panels VERY useful for the initial approach, where that sort of energy can be used to start up the coils (as very little will be needed later to keep them up (superconductive)))?

This topic includes solar wind interactions with Earth and other planetary magnetospheres and atmospheres, as well as fundamentals of solar system dynamics, formation, etc. There are many new solar system texts on the market at a sophomore level (not much math), but most have nothing about the solar wind or magnetospheres. I can cover that half of the class (at least for Earth) with Tascione's book "Introduction to the Space Environment", but I'd like something for the other half of the class (the planets, planetary atmospheres, etc.).

So, they are probably not looking at a single object >but the diffuse emission all around us. > The above comment is essentially correct. DXS is an experiment that has been in the planning stages since the early 70's. It is a soft X-ray diffuse spectrometer, meaning that it is designed to perform spectroscopic observations of diffuse emissions of x-rays from space. At soft-xray wavelengths, the sky is not black like it is in the optical. There is a diffuse glow all over the sky, which is brighter towards the galactic poles than in the galactic plane. Through a long line of reasoning that is too long to go into here, it is believed that this glow is from a million degree tenuous plasma that fills a low density region around the sun for about 100-300 light years. What has never been convincingly seen before, however, is the characteristic X-ray spectral lines from such a plasma. DXS was designed to measure those lines and allow us to measure such things as the atomic abundances in the gas at model such things as the original heating and cooling mechanisms that put the plasma in it's current state. Historical footnote; DXS was originally to fly on an October 1986 flight of the Shuttle along with BBXRT on the SHEAL-I payload. Events changed things and it was a 7 year delay before this "Hitchhiker" class, rapid science payload actually flew. It's been a long time in comming. ------------------------------ Date: Tue, 19 Jan 93 08:40:28 EST From: John Roberts Subject: Endeavour lands Endeavour landed safely at KSC, at about 8:38 AM EST.

Its rotational period is equal to its orbital period about the Earth, so it always presents the same face to the Earth. This happened because the distribution of the Moon's mass is not perfectly spherical; it's a little lumpy. Originally, the Moon was spinning more quickly than today, but over time, tidal forces working on the lumps in the Moon slowed it down until the lump with the greatest angular moment became "locked" into place, so that it always points toward the Earth.

Some of the reports are missing some, none, or all of their illustrations because the electronic files for these illustrations are not available. However, figure legends are present even when the illustrations are not. If there is a discrepancy between the electronic report and the printed report, assume that the printed document is the version intended by the author(s). What Is Available: ------------------ The pub/techreports/larc/92 directory contains PostScript files of reference publications, technical memorandums, technical papers, and technical translations produced at NASA Langley during 1992. The files are named by report type and number; e.g., file tm4382 contains Technical Memorandum 4382. The directory also contains a ASCII file called abstracts.92. This file lists the abstracts of the reports available in this directory. New reports will be added to the directory and the abstract list as they become available. The file transfer program (FTP) lets you copy the abstracts.92 file or any of the PostScript report files to your local machine. During the FTP session, use the "get" command to copy the files into your directory. When the session is completed, use the "uncompress" command to restore the PostScript files. Then, use your system print command to print the files. A Sample FTP Session: --------------------- fiddler% ftp techreports.larc.nasa.gov [login as "anonymous", give your e-mail address as the password] ftp> cd pub/techreports/larc/92 ftp> get README ftp> get abstracts.92 ftp> binary ftp> get tm4382.ps.Z ftp> bye fiddler% uncompress tm4382.ps.Z fiddler% How to Search: -------------- The abstracts.92 file can be scanned to locate information about a report in the directory. This file contains the Report Number, Funding Number, Title, Author(s), Abstract, Number of Pages, and a List of Key Terms of the reports available in the directory. Note: To make your search easier, you may want to load this ASCII file into an editor and then use it's search capabilities. How To Print: ------------- The reports are stored in the PostScript format. For storage efficiency, they are also compressed with the UNIX utility "compress". They must be uncompressed with the UNIX utility "uncompress". To learn more about the compress/uncompress utilities, type "man compress" or "man uncompress" at the command prompt. After uncompressing the report, a PostScript file remains. This file can be printed on a PostScript printer on your network, or it can be viewed on the screen with a PostScript previewer. Consult your system administrator for help performing these functions.

The new crew, Manakov and Polishcuk, arrived at the Baikonor Cosmodrome on Jan. 9/10th. They will be releaving cosmonauts Anatoli Solovyov and Sergei Avdeyev (up for 173 days now, since July 30) who are preparing for the end of their mission. In addition two other flights to Mir are planed for 1993, a joint French mission in July, and another flight at the end of the year. That final flight will provide a crew which plans to stay up for 18 months, beating the current record of 366 days. (Radio Moscow) An interesting report noted that a joint Russian/French flight tested an improved version of the Russian supersonic ramjet engine (scramjet) on top of a rocket booster. The scramjet started at Mach 3.5 (3.5 times the speed of sound) and had a successful subsonic to supersonic combustion transition at Mach 5. It ran supersonic combustion for over 15 seconds (three times longer than the flight last year) until running out of liquid hydrogen. (AW&ST Dec. 7, 14/21) Glenn Chapman School Eng.
