Endeavor ISS Flight Complete

Initial construction of the International Space Station came to a close as the Endeavour/STS-88 mission ended with a successful night landing at the Kennedy Space Center. The astronauts successfully completed all mission objectives, ending with the 10th nighttime Shuttle landing in the program's history.

International Space Station flight controllers report that all systems on the new complex are functioning normally as the station orbits the Earth at an altitude of 246 statute miles, the Unity module facing the Earth and the Zarya module facing deep space. The station was commanded to spin slowly at one revolution every 30 minutes to maintain the proper heating and cooling while it flies unpiloted for the next five months. The next shuttle assembly mission to the station is STS-96, scheduled for launch aboard Discovery in May.

Following a 4.6 million mile journey, STS-88 Commander (and Minnesota native) Bob Cabana guided the orbiter down onto runway 15, the 17th straight landing at Kennedy Space Center and the 24th in the last 25 Shuttle missions to land at the Florida spaceport. Cabana and his crewmates, Pilot Rick Sturckow, Mission Specialists Nancy Currie, Jim Newman, Jerry Ross and Sergei Krikalev all returned in great physical shape, according to NASA medical personnel.

International Space Station flight controllers at Mission Control, Houston and at the Russian Mission Control Center in Korolev, outside Moscow, will now spend the next five months monitoring the station's systems and awaiting the launch of the Discovery/STS-96 mission. That mission will see a multi-national crew of seven astronauts return to the station in a logistics resupply flight which will include at least one spacewalk to attach additional hardware to the new orbiting facility.

Live SSTV Transmitted from Mir

Live SSTV images have been transmitted from the Russian Mir space station. SSTV equipment was transported to the spacecraft earlier this fall and put on the air for the first time on December 11th. Several amateurs reported copying the images from space on 2-meters, but plans call for the SSTV transmissions to move to a 70-cm frequency that's coordinated for that purpose.

The SSTV system was turned off for several passes after December 14th, and the Mir packet system was back on 145.985 MHz -- but as of December 16th, R0MIR was transmitting SSTV on some passes and packet on others. Meanwhile, APRS developer Bob Bruninga, WB4APR, had announced a four-day APRS school experiment via Mir through December 18th.

Maxim Memorial Station W1AW copied R0MIR's SSTV pictures December 14th and 16th on 145.985 MHz. "We were able to see one of the solar panels and part of what appeared to be the lower outline of the spacecraft," said W1AW Station Manager Joe Carcia, NJ1Q. He added that Mir's signal was "pretty strong, a good 5x8 or 5x9 for most of   the pass." Before the SSTV transmission commenced, the station sent "R0MIR" in CW.

Neither of the cosmonauts aboard Mir during the current tour of duty is a licensed amateur. The SSTV equipment aboard the spacecraft was supplied to the Russians by Miles Mann, WF1F. He says the system operates in automatic mode and can display a new image every two minutes.

Mann had originally coordinated a 70-cm frequency, 437.975 MHz, for the SSTV project with AMSAT Frequency Coordinator Graham Ratcliff, VK5AGR. The 2-meter (145.985 MHz) frequency has been coordinated for FM voice and packet use. While the SSTV system is operating, the Mir packet system and the SAFEX repeater are off the air. Mann said December 16th that he's seeking to keep the SSTV system operating on 2 meters for a while longer, but added that it would likely go to 70 cm on or before January 1st.

Last reported in mode K (from Jerry, K5OE).

The RS-12/13 satellite has seen many recent changes in operation during the past weeks. Modes K, T, KT and simultaneous RS-13 operation have all been reported by a number of stations.

Tom, AD1B, reports that he has been using the RS-12/13 satellite extensively, telling ANS that recent activity level has been modest.

No official word from the satellite controllers has been received. ANS recommends monitoring each satellite carefully to determine the transponder in operation and which mode it is operating in.

RS-12/13 command is now in the hands of Alex Papkov, in Kaluga City, Russia.

RS-15

Uplink 145.858 to 145.898 MHz CW/SSB
Downlink 29.354 to 29.394 MHz CW/SSB
Beacon 29.352 MHz (intermittent)

AO-10

Uplink 435.030 to 435.180 MHz CW/LSB
Downlink 145.975 to 145.825 MHz CW/USB
Beacon 145.810 MHz (unmodulated carrier)
Operational.

AO-10 continues to function well with the exception of the periodic deep QSB, which can be partially eliminated by switching antenna polarization. Strong signals have been heard even at apogee. Also note that AO-10's apogee is approaching its most northern point (ArgP = 270). This gives the satellite track on a rectangular (Mercator) map projection a distinctly symmetrical pattern. The apogee will begin a slow migration southward.

John, W2FS, reports recent contacts on AO-10 using a 'barefoot' rig and with the satellite at 33,000 km.

Mart, DL6UAA, tells ANS that he is planning AO-10 operation from 3B8 in March and April '99. If successful, Mart says this will be the "first satellite operation from 3B8 land." Stay tuned to ANS for details. Additional information on the operation is available at http://www.qsl.net/dl6uaa/.

W4SM tells ANS that he has, using ranging software (and hardware) developed by James Miller, G3RUH, recently made ranging measurements on AO-10 for the last week and have fed these measurements into an algorithm which generates modified Keplerian elements from a "seed" set of elements. The Keplerian elements generated appear to be accurate within 16-25 km.

Note: This element set may have to be entered by hand or cut and pasted line by line into a tracking program, rather than automatically extracted. They are not in the complete AMSAT format, orbit# (Epoch rev), Element set#, and Checksum are not included.

AO-27

Uplink 145.850 MHz FM
Downlink: 436.792 MHz FM
Operational.

The TEPR settings of AO-27 were recently reset by Chuck, KM4NZ. The new settings now reflect the Earth's position during the northern fall/winter season, and should provide more satellite 'on' time for AO-27 during each pass.

Jeff, KF4KGQ, reports that he has worked stations from Canada to Mexico via AO-27 and his handheld.

Downlink 435.910 MHz FM 9600 baud BPSK
Not operational, the satellite is in JA (voice) mode.

Kazu, JJ1WTK, tells ANS that the FO-29 Command Team has released the following announcement concerning FO-29 status:

The present JA mode of operation will continue to investigate the frequency of bit errors in the on-board-computer. Reports from Amateurs on the value of channel 2A are appreciated. The position of 2A is the fifth item after 'HI HI' in CW telemetry. The normal value is '00'. Reports should be sent to lab@jarl.or.jp.

FO-29 is still in 'full sun illumination'; this should end in December.

The on-board-computer (OBC) did accept commands from ground control before full illumination began. The FO-29 Command Team says digital (JD) mode operation may be available soon. Digi-talker operation is also being planned.

OSCAR-11

Downlink 145.825 MHz FM, 1200 baud PSK
Beacon 2401.500 MHz
Operational.

Clive, G3CWV, provides the following OSCAR-11 report, dated 15-December-1998

The current duration of solar eclipse time has continued to provide OSCAR-11 with near optimum conditions, maintaining an adequate power budget while not allowing internal temperatures to rise to excessive levels. During the period 15-November to 16-December reasonable signals have been received from the 145.826 MHz beacon.

Telemetry has been nominal.

Magnetorquer spin correction counters have continued to be of interest. Recently there have been very few spin counter increments, although the spin period remains around its nominal value of -300 seconds.

The internal temperatures have fallen slightly, by about one degree C after reaching a peak last month. They are now 9.0C and 7.0C for battery and telemetry electronics respectively.

The single WOD survey, of channels 1, 2, 3, 61 (magnetometers) dated 10-October 1998, has continued to be transmitted. This current WOD starts at the normal time of 0:0:5 UTC.

Reports have been received of the mode-S beacon from Jack, W9JIU, and Victor, Ok1VKW.

The ASCII bulletin is currently a static message, detailing modes and frequencies of all the amateur radio satellites. There are additional status blocks after each bulletin is transmitted, and between ASCII TLM and WOD.

The mode-S beacon is ON, transmitting an unmodulated carrier, but telemetry indicates that it has partially failed, and delivering half power. This beacon is a useful test source for those testing mode-S converters, prior to the launch of P3-D. The 435.025 MHz beacon is normally off

More information about OSCAR 11 can be found at the following URL:

TechSat-1B GO-32

Downlink 435.325 435.225 MHz
HDLC telemetry framed so a TNC in KISS mode will decode it

The TechSat-1B micro-satellite was successfully launched from the Russian Baikonur Cosmodrome on July 10, 1998. The satellite is expected to be available for general amateur use in the future.

ANS has not received any recent updates concerning the current status of GO-32. No additional information is available at this time.

The satellite does not have a continuous beacon, but does transmit a 9600-baud burst every 30 seconds (for about 3 seconds in length), currently on 435.225 MHz.

The TechSat team has also constructed a home page about the TechSat bird, and promise they will add more information in the next few weeks. To view the site, point your web browser to:
