ISS STATUS
AMSAT NEWS SERVICE BULLETIN 143.01 FROM AMSAT HQ
SILVER SPRING, MD, MAY 23, 1999
TO ALL RADIO AMATEURS
BID: $ANS-143.01
As the International Space Station celebrates its 6-month anniversary,
flight controllers in Houston and Moscow ready both the station and
shuttle Discovery for the first visit to the outpost of the year scheduled to
begin with launch of Discovery in the early morning of May 27th.
With repairs complete on the orbiter's hail-damaged external fuel tank,
the shuttle was recently moved back to the launch pad for the final week
of processing leading to its launch (scheduled for 6:48 a.m. Eastern time
on Thursday). Discovery will carry logistics and supplies that
eventually will be used by the first crew to live on the ISS.
Preparations for Discovery's arrival call for the flight controllers to uplink
commands that will turn on heaters strategically placed around the
station to slowly warm the interior volume prior to docking and the crew
climbing on board to begin transfer operations.
Meanwhile, as Discovery was slowly rolled back to the launch pad, half
way around the world in Kazakhstan the Service Module has arrived by
train for the final months of its processing for launch atop a Proton
booster - like the rocket that launched the Zarya control module six
months ago. The Service Module will complete its testing at the Baikonur
Cosmodrome launch site in the same checkout area as Zarya prior to
being loaded in the Proton for launch scheduled this fall. The module
will provide the living quarters for the first crew scheduled to arrive on a
Soyuz rocket early next year.
When Discovery arrives at the station, it will be carrying 3,600 pounds of
supplies and hardware. Updates on the status of its launch preparations
are available on the web at:
http://www-pao.ksc.nasa.gov/kscpao/status/status.htm
The International Space Station is in an orbit with a high point of 251
statute miles and a low point of 237 statute miles, circling the Earth once
approximately every 92 minutes. The Station has completed more than
2,826 orbits of Earth since its launch. As it passes overhead at dawn or
dusk, the station is easily visible from the ground, and it will become
even brighter once Discovery has docked. Space Station viewing
opportunities for locations worldwide are available on the web at:

OSCAR-11 REPORT
AMSAT NEWS SERVICE BULLETIN 143.02 FROM AMSAT HQ
SILVER SPRING, MD, MAY 23, 1999
TO ALL RADIO AMATEURS
BID: U2RPT37.CWV
Clive Wallis, G3CWV, tells ANS that one of amateur radio's oldest
satellites in space -OSCAR-11- is doing well.
G3CWV reports that during the one-month period from April 15 to May
15, 1999 - reliable signals have been received from the 145.826 MHz
beacon. Received telemetry indicates that battery voltage during daylight
passes has continued to decrease with an average value of around 13.5
volts. Internal temperatures have continued to fall by about two degrees
Celsius during the period, due to the increasing eclipse times. Internal
temperatures are reported as 2.4C and 0.6C for battery and telemetry
electronics respectively.
In the last month the magnetorquer spin correction counters have started
to show some activity. The negative spin counter started to increment at
three counts per day where previously it was incrementing at about one
count every three days. Clive reports that at the beginning of April there
was a period when the Z-axis counter reached 1,024 - causing the
attitude control to stop. During this time the spin rate remained fairly
constant, indicating that no corrections were needed. The Z-axis counter
continues to increment normally at around 10 counts per day.
The whole orbit data (WOD) survey transmitted by OSCAR-11 shows
that during periods of sunlight the main bus voltage can be seen rising
and also being modulated by the spacecraft spin. The shape of this
modulation factor suggests that one photo cell panel may be generating
a smaller output than the others. Battery charge regulator (BCR) status
shows that the switch between A and B power units occurs when the
satellite enters or exits from the eclipse state. Channel 39 (telemetry
electronics) shows a very small change in temperature of the telemetry
electronics unit as the satellite passes through the earth's shadow.
OSCAR-11's operating schedule remains unchanged:
ASCII status (210 seconds)
ASCII bulletin (60 seconds)
BINARY SEU (30 seconds)
ASCII TLM (90 seconds)
ASCII WOD (120 seconds)
ASCII bulletin (60 seconds)
BINARY ENG (30 seconds)
The ASCII bulletin is currently a static message, detailing modes and
frequencies of many of the active amateur radio satellites.
Listeners to OSCAR-11 may be interested in visiting the G3CWV web
site. The web site contains details of hardware required and some
software for capturing OSCAR-11 data, such as decoding ASCII
telemetry and WOD. There is an archive of raw data (mainly WOD) for
analysis, which is continually expanded as new data is captured. Also
included are some audio files that are examples of each type of data
transmitted by the satellite.

ANS IN BRIEF
HR AMSAT NEWS SERVICE BULLETIN 143.03 FROM AMSAT HQ
SILVER SPRING, MD, MAY 23, 1999
TO ALL RADIO AMATEURS
BID: $ANS-143.03
ANS news in brief this week includes the following:
** The May/June AMSAT Journal will feature a complete copy of the
Dayton Hamvention Phase 3-D launch release by DJ4ZC. ANS reminds
amateurs that an AMSAT-NA membership includes the AMSAT Journal.
The May/June issue will be in the mail shortly. -ANS
** Astronomers monitoring Mars with the Hubble Space Telescope have
detected a giant storm in the northern hemisphere of the planet. The
hurricane-like spiral is complete with a central eye and was seen on two
pictures taken by a team of astronomers at Cornell University. The
images were taken using Hubble's Wide Field Planetary Camera 2.
-Sky and Telescope
** Hank, N4AFL, reports the StenSat picosatellite was recently delivered.
StenSat is a small (12 cubic inch, 8.2 ounce) satellite, which is intended
to operate as a single channel mode-J FM voice repeater. StenSat will
also periodically transmit 1200 baud AX.25 telemetry. Projected
launch date is September 15, 1999. N4AFL tells ANS that if StenSat
survives final system integration and final testing and if Stanford is
granted access to the launch platform - the team hopes to build a
revision 2 StenSat between now and September. -Hank, N4AFL
** A new 144 MHz North American DX record for high speed CW meteor
scatter was recently set with a contact from Kansas to New Jersey by
N0KQY and K2TXB. The distance covered is 1,430 miles.
-Russ, K2TXB
** A Chinese Long March 4B rocket successfully launched two civilian
satellites recently. The rocket lifted off from the Taiyuan Satellite Launch
Center in North China's Shanxi Province carrying the Fengyun 1C
weather satellite and Shijian 5 research craft. It was the first Chinese
launch of 1999. -Florida Today
** After years of planning and months of testing, anyone can now help
look for aliens! The final versions of the SETI@home software was
was recently released. Conceived in July 1996 to deal with the lack of
computing power to fully sift through the radio data now being acquired
by major programs, the concept is to put the idling of thousands of home
computers to good use. Volunteers can now download a background
program that fetches data, processes it, and returns it to the central
server. All this is performed by a screen saver program that activates
when the computer is idle for several minutes. -Sky and Telescope
** The Canadian Space Agency's first contribution to the International
Space Station, the 56-foot-long Space Station Remote Manipulator
System, has begun its campaign toward launch. SSRMS is in three
segments which when fully assembled is comprised of two booms, each
with two 12-foot sections joined by a hinge. The SSRMS will be the
primary means of transferring payloads between the orbiter payload bay
and the station for assembly. -NASA
** Some doorstep astronomy from ANS: Venus is the bright light shining
in the west-northwest after dusk. The two stars above it are Pollux and
Castor. Pollux is the brighter one, on the left. ANS invites you to watch
them shift position with respect to Venus during the week. -Sky and
