The effects of outgassing of matterials in interplanetary space. 2. Density, etc, of dust and micrometeors in interplanetary space. He is looking for the Earth - Mars area in particular. If anyone can suggest any sources of info, or even introductory info on these subjects, it would be greatly appreciated. Feel free to e-mail to me and I'll pass the information on. I'll also post info if there is interest.

Probably what is happening is that people forget to edit the header section of their messages...a common error since people are often so eager to get to writing their message that they simply skip over the header section. And every time someone adds a new newsgroup, since they think some particular tidbit in their post will interest a new group of people, the thing gets longer and longer, etc. I don't think it's any deliberate attempt to harrass the people in sci.optics. I can also understand the desire to keep sci.optics "pure"--we all have only so much time and we want to get to the articles that fill our specific interests without having to wade through a lot of other stuff. (Check out misc.headlines sometime and you'll see what I mean.) I would think people in optics would be fascinated by all the space-related aspects of their field, but I can also see why they wouldn't want these to crowd out other equally important aspects. My only "objection" to the last post, and it's a minor one, is the suggestion that we place ideas like terraforming in a group called sci.whimsy. The word whimsy implies foolish hopefulness, silly ideas that just are not practical and should not really be pursued. Sci.speculation was a much better suggestion, although I think an even better one might be sci.future.potential. I think the last place we need to be discouraging original thought is in the sciences; these days, it seems like the ground is so barren, so arid, that those seeds should get all the help we can give them. ------------------------------ Date: 2 Mar 91 21:23:00 GMT From: ka2qhd!kd2bd@rutgers.edu (John Magliacane) Subject: * SpaceNews 04-Mar-91 * SB SPACE @ AMSAT < KD2BD $SPC0304 * SpaceNews 04-Mar-91 * Bulletin ID: $SPC0304 ========= SpaceNews ========= MONDAY MARCH 4, 1991 SpaceNews originates at KD2BD in Wall Township, New Jersey, USA. It is published every week and is made available for unlimited distribution. * RS12/RS13 NEWS * ================== This turned out to be a banner week for the new satellites (RS12/13 and AO21). Mode A of RS-12 was turned on earlier in the week and the beacon on 29.408 was described as very loud. However, later in the week, it was reported that there may be a problem with RS-12 caused by interaction with the Main Payload Cosmos 2123. Ed O'Grady, KE2VC, was listening to RS-12 on Mode A and heard an inordinate amount of CW in the passband and after listening for a few seconds determined that it was in fact the unmistakable sound of navigation satellite signals. Upon retuning his FT-736 over to 150.000 (Cosmos 2123's frequency) discovered a perfect match!. Apparently, the Nav downlink (which had not previously been observed) is getting in to the amateur 2M receiver. This appears to be reminiscent of a similar situation with RS10/11 and its parent, Cosmos 1861. [Story via ANS] * OSCAR-21 NEWS * ================= Peter, DB2OS, reports that the AO-21 RUDAK beacon and RM-1 CW beacon was switched on around 2140 UTC on 22 February 91, 6 days earlier than expected. GEOS had stated last week that they would not power up our equipment before 28 Feb. While waiting for the next UO-14 pass, Peter had his receiver on 145.975 when the squelch opened and he found RUDAK-2 transmitting 400 Bit/s PSK telemetry (AO13 format) on 145.983 MHz with an extremely strong signal! The CW beacon on 145.822 was also on with very good signals. Once software is uploaded to RUDAK-2, the RUDAK beacon will be switched to 1200 Bit/s PSK AX.25 (like FUJI, PACSAT etc) transmitting telemetry and short bulletins. The ROBOT modes and RUDAK MAILBOX RBBS will be switched on later after final check-outs. Watch the RUDAK beacon, UO-14, and ANS for further information. [Story via ANS] * METEOR OBSERVATIONS * ======================= Peter Wright, DJ0BI, of Muhlingen, West Germany would like to get in touch with those involved in meteor observations. Peter uses a fully automatic camera of his own construction that has a revolving shutter, giving 12.5 darkenings a second. His automated system takes one or two photographs per night for one month and records meteor observations onto a 9x12 cm flat film. In addition, Peter uses a radio forward scatter unit that writes data to a pen recorder to gather radio observations of meteor activity. Using this information, Peter, along with members of a European network of meteor observers, calculate flight patters of meteors in an attempt to retrieve fallen material. If anyone is interested or is already involved in meteor observations, Peter asks that they contact him, since he has a large quantity of information on this subject to share with others worldwide. Peter may be contacted by mail by writing: Peter Wright, DJ0BI Steinbuhl Str 8 7769 Muhlingen West Germany or by packet radio: DJ0BI @ OE9XPI (in Austria). * STS-37 SAREX NEWS * ===================== In a packet mail exchange between U2MIR and W5RRR recently, Musa was asked if he would still be on board during the STS-37 mission in April. Musa replied he will be on Mir until May 20, 1991. This means there is another opportunity for a space to space contact between Mir and the Shuttle using amateur radio. The exact launch time and exact orbit of Mir will determine when the contact can take place, a few minute difference in the launch time could leave the Shuttle with no conjunction during the 5 day flight. It will not be known until after launch if and when the conjuctions will occur. SAREX experimenters report that testing of the flight hardware on board the orbiter went well last week. The 2m (144-145Mhz) packet, slow-scan and voice equipment were checked out, as well as the 70cm FSTV receiver and miniature TV/VCR and Camera that will be carried as part of the experiment. The only glitch was the failure of a piece of ground test equipment, the FSTV transmitter modulator failed. This prevented complete verification of the FSTV receiver while in the orbiter. An unmodulated carrier was received and the FSTV receiver has been thoroughly tested at JSC, so no problems are expected. Unfortunately, due to Shuttle hardware problems, the Shuttle is now grounded for at least four months, effectively eliminating the possibility of a Shuttle <==> Mir Amateur Radio contact.
