40TH ANNIVERSARY OF THE FIRST WEATHER SATELLITE
AMSAT NEWS SERVICE BULLETIN 093.01 FROM AMSAT HQ
SILVER SPRING, MD, APRIL 02, 2000
TO ALL RADIO AMATEURS
BID: $ANS-093.01
April 1, 2000 marked the anniversary of the launch of the worlds
first weather satellite - a single event that forever changed our
lives.
The first weather satellite, a polar-orbiting satellite named TIROS,
was launched from Cape Canaveral on April 1, 1960. The Television
Infrared Observation Satellite demonstrated the advantage of mapping
the Earth's cloud cover from satellite altitudes. TIROS also showed
clouds banded and clustered in very unexpected ways. Sightings from
the surface had not prepared meteorologists for the interpretation of the
cloud patterns that the view from an orbiting satellite actually showed.
Today, our nation's environmental satellites are composed of both
geostationary environmental satellites (for national, regional and
short-range warning) and polar-orbiting environmental satellites (for
global, long-term forecasting and environmental monitoring).
Each day, these satellites send global measurements to ground station
computers, adding vital information to forecasting models, especially for
remote ocean areas, where conventional data is lacking.
The United States also operates two meteorological satellites in
geostationary orbit, one over the East Coast and one over the West
Coast with overlapping coverage over the United States. Currently,
GOES-8 and GOES-10 are in operation.
ANS congratulates the agencies and the many people who were
responsible for this technological advancement and thanks all of
them for the quality they added to our daily lives.

SHUTTLE ISS MISSION FLIGHT DELAYED
AMSAT NEWS SERVICE BULLETIN 093.02 FROM AMSAT HQ
SILVER SPRING, MD, APRIL 02, 2000
TO ALL RADIO AMATEURS
BID: $ANS-093.02
The upcoming space shuttle mission to the International Space Station
will be delayed to give the commander of the shuttle Atlantis more time
to train after an ankle injury. NASA officials told ANS the Atlantic ISS
mission has been rescheduled to April 24, 2000. The flight had been
targeted for April 18th.
The commander, Air Force Colonel James Halsell, recently injured his
left ankle during training at the Johnson Space Center in Houston. "He
needs time to complete his training activities,'' NASA spokesman Bruce
Buckingham said. Buckingham also said some of the other Atlantis
crewmembers joined the team "fairly late'' but that their training has now
been completed.
The late-arriving crew joined the Atlantis team after the decision was
made to split the April mission into two flights because of Russian delays
in completing the Zvezda service module. A second Atlantis flight is
planned for mid-August after the scheduled July launch of the Russian
module, which is to supply early living quarters and propulsion. Only
after ISS living quarters are established will Amateur Radio operation
begin from the orbiter.
The April 24th mission from the Kennedy Space Center will be a nine
day, 19-hour mission to service the two connected pieces of the station
that now are in orbit. The mission also will include a spacewalk. The
flight is one of at least 40 flights and 1,700 space walks planned
during the next five years to the space station. As ANS readers know,
the United States, Russia and 14 other nations are building the
1-million-pound station -- which will be roughly the size of two football
fields when completed.

ASTRONOMY DAY
HR AMSAT NEWS SERVICE BULLETIN 093.03 FROM AMSAT HQ
SILVER SPRING, MD, APRIL 02, 2000
TO ALL RADIO AMATEURS
BID: $ANS-093.03
Sky & Telescope informed ANS that Saturday, April 8, 2000 is
Astronomy Day. On this weekend, astronomy clubs, planetariums, and
other groups of sky lovers across the United States (many from the
Amateur Radio satellite community) will band together to show
the public how much fun astronomy can be.
In many communities, members of the local astronomy organization will
host evening 'star parties' to let the public look through a telescope,
others are planning informative displays at local malls, schools and
libraries to show what skygazing is all about.
ANS adds that this would also make a great time to plan a 'visual
satellite event' and watch several of your favorite birds pass overhead
during orbit!

SILVER SPRING, MD, APRIL 02, 2000
TO ALL RADIO AMATEURS
BID: $ANS-093.04
ANS news in brief this week includes the following:
** Sea Launch reports significant progress in the investigation of the
March 12th launch failure. Preliminary investigations indicate
off-nominal operation of the second stage propulsion system. All other
systems appear to have performed as expected. Preliminary findings of
the launch failure have indicated command and control software failed to
command a valve on the rocket's second stage to close. The open valve
may have caused the second-stage propulsion system to lose 60
percent of its power. -Florida Today
** In and earlier bulletin set, ANS talked about the April 2nd AMSAT-DC
meeting event. Speakers included Joshua Rozovsky, N3YAR, Bob
Bruninga, WB4APR, John Sortor, KB3XG, Jerry Rodski, K3MKZ, Dan
Schultz, N8FGV, Frank Bauer, KA3HDO and Will Marchant, KC6ROL.
The AMSAT-DC meetings was underway as this edition of ANS was
being transmitted on 20-meters. -Pat, WD8LAQ
** Daylight saving time began in most of the U.S. and Canada this
weekend. Arizona, Hawaii, and parts of Indiana do not follow the
time switch. ANS reminds those that do follow the time change to be
sure you have made the move to 'spring forward' an hour. -NN0DJ
** The two cosmonauts expected to take part in the final mission to
Russia's Mir space station arrived at the Baikanour launch pad recently.
They have began final preparations for the upcoming launch.

Uplink 145.975 MHz FM
Downlink 435.070 MHz FM
Operational, mode J.
Chris Jackson, G7UPN / ZL2TPO reported on the AMSAT bulletin board
that UO-14 --launched in January 1990-- spent its first 18 months in
orbit operating as an Amateur Radio store-and-forward satellite. It was
then switched for use by Volunteers in Technical Assistance, who used it
for medical messaging into Africa. "Since the computer which is used for
store-and-forward communications is no longer able to perform that task,
UO-14 is no longer usable in this mode," reported G7UPN. "It is, however,
possible to use the satellite as a single-channel FM voice repeater, and I
have configured the satellite to do this."
Mike, KD9KC, reports that "UO-14 is working great." In the last 2 weeks
Mike has worked 15 new grid squares via UO-14.

SUNSAT SO-35
Operational. SunSat has been in mode-B (FM) using an uplink
of 436.291 MHz (+/- doppler) and a 145.825 MHz downlink.
SunSat was launched February 23, 1999 aboard a Delta II rocket from
Vandenberg Air Force Base in California, recently celebrating its first
year in orbit.
The SunSat package includes 1200 and 9600 baud digital
store-and-forward capability and a voice 'parrot' repeater system
that will be used primarily for educational demonstrations.
The satellite has two VHF and two UHF transmit-receive systems.
Due to an improvement in its power budget, SunSat's Mode B repeater
will now also be enabled on most weekday evenings (except Monday).
A schedule of the active passes can be found at:

SEDSAT-1 SO-33
Downlink 437.910 MHz FM 9600 baud FSK
The satellite is not currently available for uplink transmissions and
image and transponder recovery efforts have been unsuccessful.
SedSat-1, signifying Students for the Exploration and Development of
Space Satellite number one, was successfully launched and placed in
orbit on Saturday, October 24, 1998.
SedSat-1 has downlinked months worth of telemetry data on the
performance of its electrical power system parameters. The Nickel
Metal Hydride batteries on the spacecraft were experimental and
experienced some abuse due to a power negative situation. This
information has provided NASA with useful information. With the
exception of the imaging system and the use of the transponders,
SedSat-1 has been judged a success.
