SPACE FAIR '98 PART 2 A SUCCESS
HR AMSAT NEWS SERVICE BULLETIN 116.01 FROM AMSAT HQ
SILVER SPRING, MD, APRIL 26, 1998
TO ALL RADIO AMATEURS
BID: $ANS-116.01
Keith Pugh, W5IU, AMSAT-NA Vice President of Operations, tells ANS that the
amateur radio satellite demonstrations at the Riverside Applied Learning
Center was a huge success. As ANS reported last week, Riverside Applied
Learning Center is an elementary school for 'special kids' in the Fort
Worth, Texas area. The school has placed emphasis on learning about outer
space this year. Last week approximately 200 students and parents from the
school attended a 'Mir Visual Sighting Party' and were treated to a
"perfect 60 degree elevation Mir pass," said W5IU.
Satellite demonstrations took place on Friday, April 24th. Operators
participating from Riverside were W5IU, WB5QLD and KG5OA. Satellites
utilized in the on-air demonstrations included FO-20, FO-29, AO-27, AO-16,
LO-19, UO-22, KO-23, KO-25 and Mir. Contacts were made on the analog
(voice) satellites and messages were also received on the digital
satellites from the USA, Canada, United Kingdom and Austria. W5IU and crew
also uploaded several digital messages. Keith also tells ANS it's not too
late to send greetings to the school, just send a message to W5IU on any of
the current pacsats.
In addition to satellite operation, high frequency contacts were made with
AD6P, AA0QP, KI0MN (at W0WR), the Kansas Cosmosphere Station in Hutchinson,
Kansas, with WA4SIR (at WA3NAN), the Goddard Space Flight Center Radio Club
in Greenbelt, Maryland and with WB8IMY at W1AW, the ARRL Headquarters
Station in Newington, Connecticut. W5IU passes on a special thanks to Ron
Parise, WA4SIR, for the patience and grace he displayed in answering the
many questions from the students about his experiences as an astronaut.
Space Fair '98 is not over yet. Mike, WB5QLD, will be back at the school on
Monday, April 27th to participate in the next MIREX school test through
Mir.
W5IU closes his report by saying, "for those of us that worked at the
school, the enthusiasm displayed by these young children was the best
reward we could possibly receive. Thanks again to all that participated."

Pupils at Newman Elementary School in Needham, Massachusetts were the
latest to get a chance to speak with US astronaut Andy Thomas, KD5CHF,
aboard the Russian Mir space station. On April 13th, some 14 fifth graders
asked questions about life aboard Mir, Mir-shuttle dockings, and the duties
of the Mir crew. AMSAT/SAREX Technical Mentor Randy Becnel, KC5YJI, called
the contact "highly successful." The QSO was made possible via a telebridge
with Ellen Baker, KB5SIX, in Houston, Texas. Students got to speak with
Thomas for the full 10-minute pass and without interruptions.
Becnel said having Baker as the station operator turned out to be "an added
and unexpected bonus" for the youngsters. A relative of hers attends Newman
Elementary, and she has visited the school previously to talk to the
students about life in space.
Teacher-coordinator Angela Dinapoli also had met with Baker during a visit
to Johnson Space Center. After the contact ended, Baker talked about ham
radio and encouraged the kids to consider it as a hobby.
On hand for the occasion were local media as well as parents, other
teachers and students. In an effort to involve as many of the youngsters as
possible, teachers assigned several student reporters to cover the contact
and write an article for the school's magazine, called the Dragonfly.
Since Mir-school contacts resumed earlier this year after a one-year
hiatus, schools in several states have had a chance to chat with Thomas, a
native of Australia. Two Connecticut schools remain on the schedule for Mir
contacts in May. Additional contacts are possible before Thomas returns to
Earth in June. As it now stands, Thomas will be the last US astronaut to
serve a tour of duty aboard Mir. Thomas' Russian crewmates, Talgat
Musabayev, RO3FT, and Nikolai Budarin, RV3FB, have performed a series of
space walks in the past couple of weeks, to make repairs to the aging space
outpost.

Bob Bruninga, WB4APR, reports over 40 schools have signed up for the
upcoming MIREX School Test. This test will allow amateur radio stations,
especially school club stations, to transmit APRS position reports through
the Mir Space Station on Monday, April 27th. MIREX has authorized APRS
packets for most passes that day between 10:00 and 23:00 UTC.
WB4APR tells ANS that it was successfully demonstrated in the last test
that more than 30 stations per footprint can be sending APRS position
reports through Mir, and Bob says there is room for a few more
experimenters, especially in Europe. However, Bob reports that to keep from
saturating the channel, MIREX must be selective in asking other stations to
participate. MIREX is asking non-school APRS stations to transmit UI
position reports via MIR (only) if they are included in any of the
following categories:
Youth Groups
Trains
Boats
Aircraft
Backpack portable running on battery power
MIREX is asking all stations not to send any conventional traffic to the
Mir Crew via the PMS System regarding this experiment. Mir does not have
MIRMON or APRS software on board and are not familiar with the test. They
are being informed via MIREX (only).
The following URL's will be of interest during the MIREX
School test:

saying he was very busy, although he hoped to spend a while longer at the
mic. KC2BBU monitored a R0MIR voice contact on April 24th at 15:00 UTC.
Costa, CT1EAT, reports working Andy recently on 145.985 MHz with 5X9+20/9
signals. WB4APR reports from the US Naval Academy Satellite Lab that
during the annual review (and) while the Admiral in charge of Naval Space
Command was touring the facility, WB4APR conducted a completely at random
two-way chat with Andy. Bob reports most of the VIP's at the Naval Academy
were in attendance, and yes, they were impressed. Bob says that even the
best planning could never have accomplished this kind of luck, adding,
"thank you ham radio!"

been unsuccessful.
Transponder information on RS-16.
Uplink = 145.915 - 145.948 MHz
Downlink = 29.415 - 29.448 MHz
Beacons = 29.408 and 29.451 MHz

AO-10
Uplink 435.030 to 435.180 MHz CW/LSB
Downlink 145.975 to 145.825 MHz CW/USB
Semi-operational.
Stacey Mills, W4SM, reports solar illumination on AO-10 appears to be
way down and the satellite is nearly "comatose." W4SM can hear the
beacon (with FMing) and can hear his downlink as well, but the signals
are very, very weak.
This condition is in keeping with W4SM's best guess regarding attitude,
which shows less than 50% solar panel illumination at the moment.
Given the age of the panels, that's probably enough to cause significant
performance degradation.
Things will probably continue to get worse for the next month and
may not be any better by Field Day. However, they should improve
again later in the summer and peak in August.
W4SM has more information about the satellite on his AO-10 web page, using
the following URL:
