(No replies to me, please!) --------------------------------------------------------------------------- ***** NEWS FLASH ***** NEWS FLASH ***** NEWS FLASH ***** The Roadblocks to Space As many of you may know, Space Travel Services, Corp. was founded in 1990 to give the average American citizen a chance to get into space. To that end, its organizers started a sweepstakes in which the winner would win a free trip to the Soviet space station "Mir". Unfortunately, the district attorney's office in Harris County, Texas, had the company officers arrested on Wednesday, Feb 6th for felony gambling promotion. They were handcuffed and held in a police car for an hour -- two blocks from the jail -- and then paraded before the media, who coincidentally happened to be there when they finally arrived. At this staged media event, the DA issued a rediculous statement denouncing the company as "evil". According to Jim Davidson (who I've known for about three years), six lawyers have advised him that the DA's office does not have a legal leg to stand on. Unfortunately, the DA has frozen Space Travel Services' checking accounts, so they cannot defend themselves with company funds. And they need $20,000 within a week (for work that the criminal lawyers have already done). To solve this problem, the Space Frontier Foundation, with the help of the Houston Space Society, is instituting a legal action fund for space activities whose first project is to aid the defense of these two space entrepenuers. The Space Frontier Foundation is a media-oriented public interest pro-space group whose goal is to change how the American people think about space. Space should be viewed as an open frontier of opportunity for everyone, and not the private domain of an elitest bureaucracy. (example quote: NASA should *open* the door - not *be* the door). SFF can be reached at 612 641-1930. The officers include: Jim Muncy, Chairman; Rick Tumlinson, President; Greg Barr, Vice Presicent; Tim Kyger, member of the board (and Congressman Dana Rohrabacher's legislative aide on space). Bjo Trimble, who helped lead the science fiction fan community to rename the first (non-orbiting) shuttle to Enterprise, will be helping to administer the project. She can be reached at (703) 359-4284 James Thomas, CPA, a non-spacer who is not connected to the company, will be administering the financial aspects of the project. Space Travel, Inc. can be reached at 713 333-4046, and their fax number is 333-4047. Donations can be sent to: Space Travel Legal Fund C/O James R.

That's why you only see infra-red telescopes at very high altitudes (to get above the water vapour at lower altitudes) or in space. Infra-red images are useful for weather satellites: an infra-red image can give you the temperatere of the highest layer of cloud, which can then be translated to the height said cloud. This is useful for predicting the severity of thunderstorms (i.e high tops == severe thunderstorms). I got this info when I visited an FAA flight service station once. ------------------------------------------------------------------------------- Never trust a pilot with clean hands.| Andrew Tron at Princeton University Never address a major international | awtron@phoenix.princeton.edu (Internet) terrorist as "Bubbi". | uunet!phoenix!awtron (UUCP) ------------------------------ Date: 14 Feb 91 17:58:40 GMT From: swrinde!elroy.jpl.nasa.gov!jato!mars.jpl.nasa.gov!baalke@ucsd.edu (Ron Baalke) Subject: Magellan Update - 02/14/91 MAGELLAN STATUS REPORT February 14, 1991 The Magellan spacecraft is performing nominally. All STARCALS (star calibrations) and DESATS (desaturations) in the past 24 hours were successful. The attitude updates averaged 0.049 degree. Magellan is now in mapping orbit #1010 and the radar system performance is nominal. The spacecraft temperatures have stabilized at an acceptable level. Where Battery #1 had peaked at 27.2 degrees Celsius on the last full mapping pass, it now peaks at 23.5 degrees. The transmitter is at 53 degrees and the gyroscopes at 67 degrees. The strategy of shortening the mapping pass by ten minutes cuts 26 degrees of latitude off the southern end of the delayed image swaths. Over the 17 to 21 days that this this strategy will be used for temperature control, the loss of image area will be less than 1% of the Venus surface. ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@mars.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | Is it mind over matter, ___| | | | |__) |/ | | |___ M/S 301-355 | or matter over mind? /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | Never mind. |_____|/ |_|/ |_____|/ | It doesn't matter. ------------------------------ Date: 15 Feb 91 19:55:39 GMT From: sdd.hp.com!think.com!masscomp!ocpt!tsdiag!davet@ucsd.edu (Dave Tiller N2KAU) Subject: Re: Liquid SCUBA In article <11350@jpl-devvax.JPL.NASA.GOV> jenkins@jpl-devvax.JPL.NASA.GOV (Steve Jenkins) writes: -In article dlbres10@pc.usl.edu (Fraering Philip) writes: ->In article <1991Feb4.173100.1@happy.colorado.edu> sesharp@happy.colorado.edu writes: -> ->>[....] Premature babies often die ->>of collapsed lungs because they don't produce sufficient surfactants to ->>hold them open against surface tension. -> ->Could you reference the study please? - -Premature infants are at risk because their underdeveloped lungs are -uncompliant for lack of pulmonary surfactant.

The article pointed to the possibility only of launching expendable boosters at 1/25th the shuttle's cost. The author used possibly erroneous speculation as to the true cost of launching on the shuttle, including the cost of Endeavor and of keeping NASA idle for two years (his figure was about $6,800/lb.) and quoted hydrazine/nitric acid or kerosene/lox, without regenerative cooling, turbopumps or gimballed engines at $350/lb for 50-ton loads.

Shelton, 1974, National Geographic Society, Washington, D.C., pg 148: "...A few seconds later, a 68-inch probe extending down from the LM touched the moon, turning on a contact light on the instrument panel. Instantly, Armstrong shut off the engine. They felt a jolt like that of a jet touching down on a runway. "'Houston, Tranquillity Base here,' Armstrong finally reported. 'The Eagle has landed.' "The next step was to walk on the lunar plain and pick up priceless pieces of pay dirt, but it took a while to get ready--about 6.5 hours of scheduled rest and preparation. "As Armstrong, the first lunar prospector, descended the ladder, he pulled a lanyard that unfolded and positioned a television camera. The world thus saw him slowly make his was down to the surface and heard him describe his progress." On page 152 thre's a picture of the B/W TV images sent back from that camera. It shows Armstrong about to take his last step off the ladder onto the surface. There's also a color picture of some folks sitting around watching the event on television. The caption reads: "Arabs in Kuwait gather before a television set during the Apollo 11 mission to witness man's farthest journey. An estimated five hundred million people -- a seventh of the population of earth-- watched Astronaut Neil Armstrong as he took his 'small step' (above), televised to earth from a camera mounted on the Eagle's descent stage." I thought that was just a little bit ironic. :) -- =============================================================================== Ken Sheppardson Email: kcs@sso.larc.nasa.gov Space Station Freedom Advanced Programs Office Phone: (804) 864-7544 NASA Langley Research Center, Hampton VA FAX: (804) 864-1975 =============================================================================== ------------------------------ Date: 15 Feb 91 17:21:33 GMT From: usc!elroy.jpl.nasa.gov!freedom!xanth!mcdowell@ucsd.edu (Jonathan McDowell) Subject: Jonathan's Space Report, Feb 14 Jonathan's Space Report Feb 14 1991 (no.65) Space Report may continue to appear somewhat irregularly as I settle in to my new home in Huntsville.

The crew have performed three spacewalks so far. The first on Jan 7 repaired the EVA hatch on Kvant-2. The second and third on Jan 23 and Jan 26 set up a crane on the outside of the Mir core module which will be used in later spacewalks to transfer solar panels from the Kristall module to the Kvant module at the other end of the station. Orbiter Discovery, in the VAB, was mated to the STS-39 tank and boosters on Feb 11. Launch is due in early March. Atlantis and Columbia are in the Orbiter Processing Facility, and the boosters and tank for STS-37, the next Atlantis mission, have been mated in the VAB. Kosmos-2121, launched Jan 17, is a Vostok class recon satellite replacing Kosmos-2120 which landed the same day. Kosmos-2122, launched Jan 18, is an ocean surveillance satellite which tracks naval radio emissions. Informator-1 was launched Jan 29 by a Kosmos R-14 into a 1000 km polar (83 degree) orbit, the same orbit used by the Tsikada and Nadezhda navigation satellites. I think it's a position-locator satellite like Geostar, but my files are still in the moving truck somewhere in the Eastern US and I don't have access to Pravda or TASS at the moment (any volunteers?) Kosmos-2123 was launched Feb 5 by a Kosmos R-14. It appears to be a standard Soviet military Transit-equivalent navigation satellite, in a similar orbit to Informator-1. ___________________________________ |Current STS status: | |Orbiters | | | |OV-102 Columbia OPF Bay 1 | |OV-103 Discovery VAB Bay 1 | |OV-104 Atlantis OPF Bay 2 | | | |ML/ET/SRB stacks | | | |ML1/STS-37/ET VAB Bay 3 | |ML2/STS-39/ET/OV-103 VAB Bay 1 | ----------------------------------- (c) 1991 Jonathan McDowell .-----------------------------------------------------------------------------. | Jonathan McDowell | phone : (205)544-???? | | Space Science Lab ES65 | uucp: | | NASA Marshall Space Flight Center | bitnet : | | Huntsville AL 35812 | inter : mcdowell@xanth.msfc.nasa.gov | | USA | span : ssl::mcdowell | '-----------------------------------------------------------------------------' ------------------------------ Date: 14 Feb 91 17:26:54 GMT From: mintaka!olivea!samsung!zaphod.mps.ohio-state.edu!lavaca.uh.edu!jetson.uh.edu!cheehh@bloom-beacon.mit.edu Subject: Re: SPACE Digest V13 #102 (What's the Moon good for?)
