SB NEWS @ AMSAT $SPC0408
* SpaceNews 08-Apr-96 *
BID: $SPC0408
=========
SpaceNews
=========
MONDAY APRIL 8, 1996
SpaceNews originates at KD2BD in Wall Township, New Jersey, USA. It is
published every week and is made available for non-commercial distribution.
* MIR NEWS *
============
Just a reminder that Mir has once again become active with a communications
downlink on 143.625 MHz when over the United States mainland. Strong signals
can be copied from Mir on this frequency.
In other Mir news, Shannon Lucid has been heard making frequent Amateur
Radio contacts on 145.550 MHz. It is also interesting to monitor both
143.625 MHz and 145.550 MHz during a Mir pass. Sometimes Shannon can be
heard in the background on 143.625 MHz as she works stations on 145.550 MHz.
Douglas Quagliana, KA2UPW, reports that the Columbia Broadcasting Company
(CBS), along with NASA and the Russian Space Agency have agreed to send
the CBS World News Report and presumably some other CBS News reports to
Shannon Lucid during her stay on the Russian space station MIR. CBS
announced that they would be continuing to send news updates to MIR for
the next two years to allow future astronauts and cosmonauts to keep up
with current events.
* SSTV ON OSCAR-13 *
====================
Slow-scan television (SSTV) communications have been taking place on
AMSAT-OSCAR-13 for a number of years. Signals are reported to be very
strong prior to and immediately after scheduled Mode S periods. SSTV
quality is directly dependent on signal strength so now is the time
get your best pictures on the air.
Slow scanners are invited to join the SSTV sessions on OSCAR-13, which
take place on a downlink frequency of 145.955 MHz. An SSTV net meets
at 45 minutes before Mode S, and on Mode B following Mode S on Saturdays
and Sundays. This is NOT a formal net. Feel free to join the group at
any time, but DO ask for your turn in the queue.
Join these sessions or contact wb6llo@amsat.org for other skeds and he
will coordinate your efforts.
For those not familiar with satellite SSTV, operation is simplicity itself.
Before transmitting your picture, send a brief description of what you are
about to send and indicate the mode. When on the receive end, tune to what
you assume to be a normal voice pitch.

* AMSAT-OSCAR-13 SCHEDULE *
===========================
The re-orientation to attitude ALON/ALAT 180/0 is complete, and the new
transponder schedule is now in place:
M QST ** AO-13 TRANSPONDER SCHEDULE ** 1996 Mar 30 - 1996 Jun 17
Mode-B : MA 0 to MA 70 |
Mode-BS : MA 70 to MA 120 |
Mode-S : MA 120 to MA 122 |<- S beacon only
Mode-S : MA 122 to MA 140 |<- S transponder; B trsp. is OFF
Mode-BS : MA 140 to MA 180 | Alon/Alat 180/0
Mode-B : MA 180 to MA 256 | Move to attitude 220/0, Jun 17
Omnis : MA 230 to MA 25 |
Note that the higher powered engineering beacon 145.985 MHz is ON for two
periods: MA 0 - 25 and MA 90-100.

* AMSAT CALL FOR PAPERS *
=========================
The 1996 AMSAT Annual Meeting and Space Symposium will be held on
November 8-10, 1996 at the Holiday Inn, City Center in Tucson, AZ.
This is the first call for papers to authors who wish to submit papers
for this event. As always, the scope of the papers should be on topics
of interest to the amateur satellite service.
Topics may include, but are certainly not limited to:
The Life and Times of AO-13
Building a Phase-3D Ground Station
Phase-3D Construction Topics
DSP-93 Integration
AMSAT Field Operations
What's Next for AMSAT After Phase-3D?
We also would like to solicit topics from the AMSAT community. In other
words, what topics would YOU like to see presented at this year's Annual
Meeting?
Abstracts from authors should be submitted by June 15, 1996. Final
versions of all papers should be received by August 15, 1996.
Submissions and inquiries should be made to Dave Burnett, WD8KRV:
By Internet: wd8krv@amsat.org
By Mail: G. D. Burnett
4809 E. Pima #223
Tucson, AZ 85712
Information about the Annual Meeting home page will be included in a future
announcement. We look forward to seeing you at the Annual Meeting!
73,

* LINUX IN SPACE FOLLOW-UP *
============================
Astronaut Dr. Ronald Parise, WA4SIR, has provided some details regarding
use of the Linux operating system on Space Shuttle during mission STS-75.
According to Ron, Linux was used on an IBM Thinkpad laptop computer in
support of the tether experiments carried on STS-75. Since the ground
based applications to control those experiments ran on a DEC Alpha, a
64-bit computer made by Digital Equipment Corporation, it was a simple
matter to port those applications to a Linux system for use on a laptop
carried on the Space Shuttle.
Pat Kilroy, WD8LAQ, reports that Ron Parise uses Linux on his PCs at
home and also installed it at the WA3NAN club station network at the
NASA Goddard Space Flight Center, in Greenbelt, Maryland.
Another report carried on Usenet indicated that X-Window System based
software running under the Linux operating system was used on the Space
Shuttle to display acceleration data from the Space Acceleration Measurement
System (SAMS) to the crew during crew exercise periods in the microgravity
science phase of the mission.
