Mir Crew Returns to Earth

News agencies around the world all reported the same story: for the first time in over 10 years, there's nobody in space. Todd Halvorson of the newspaper Florida Today told ANS that "in an emotional overture to a fiery grand finale, an international crew left Russia's aging space station Mir early Saturday morning, reducing Earth's orbital population to zero." The crew's departure also signaled an end to amateur radio operation aboard the Mir station.

Mir had been occupied for 3,641 consecutive days.

The departure followed a hectic two weeks in which the crew shut down station laboratories, filled up its garbage scow and switched off all but essential systems. A new crew, meanwhile, is being trained for a short mission that might be needed to make final preparations for what would amount to a burial-at-sea. The schedule calls for cosmonauts to fly to Mir in February or March of 2000 and to oversee the arrival of a fuel-filled Russian space freighter. The freighter would periodically fire onboard thrusters, nudging Mir into a lower orbit of about 125 to 135 miles above Earth. The crew then would abandon ship and return to Earth before the freighter gives Mir a powerful last push into the upper atmosphere.

Mir has placed some incredible numbers in the record books, starting with orbits. Mir orbits the Earth about 16 times a day, for total of more than 77,000 to date. The station has been aloft for almost 5,000 days going back to the core component launch and has seen nearly 100 passengers, including seven NASA astronauts, a Japanese journalist, a British candymaker and several other foreign visitors. Mir was also the setting for the longest stay in space by Cosmonaut Valery Polyakov (recording 438 days in 1994-95). Many of the visitors were ham operators who were very 'radio-active' from the station during their stay.

Many satellite operators posted comments on the AMSAT-BB about Mir. Jeff, W4JEF, essentially captured the thoughts of many with his posting, "may the memory of the fun we've all had with Mir remained etched in our minds for years to come."

[ANS congratulates the Mir space station and all who flew on her for their outstanding achievements]

StenSat Launch Update

Amateur radio satellite operators around the world are watching, with much interest, the upcoming launch of the very small (and very intriguing) StenSat amateur radio picosatellite. StenSat is a tiny (12 cubic inch) FM crossband repeater in the sky, which will operate much like the popular AO-27 satellite. StenSat will use an uplink frequency of 145.840 MHz and a downlink of 436.625 MHz.

Hank Heidt, N4AFL, tells ANS that StenSat will be part of the Stanford University's OPAL (Orbiting Picosatellite Automated Launcher) experiment, currently scheduled for an October 4, 1999 launch.

Stay tuned to ANS for launch details as they become available.

N4AFL and his team are looking for volunteers to monitor and control the StenSat picosatellite. The team is particularly interested in getting AX.25 style telemetry reports from the satellite in the first hours after launch. In addition, N4AFL is looking for volunteer control operators who can help switch the operating modes of the bird (using standard DTMF tones).

If interested in volunteering, contact N4AFL at hheidt@erols.com

Details on the StenSat picosatellite is available on the web at http://www.erols.com/hheidt

ARISS Antenna Update

The ARRL is reporting that hardware key to ham radio involvement in the International Space Station program has been sent to the flight processing facility at NASA Goddard Space Flight Center. According to SAREX Principal Investigator Matt Bordelon, KC5BTL, "once all the equipment is in hand, the antenna system components will be integrated and undergo flight qualification testing."

KC5BTL tells ANS that the ARISS program calls for eventually providing HF capability from ISS. "We haven't done HF before from the shuttle or Mir and a lot of hams have really wanted us to go in that direction." Running HF gear from the space shuttle was deemed impractical before, said Bordelon, because the SAREX program depended on a window style antenna.

Things will be different with the four, externally mounted antennas on the ISS Service Module. The ARISS Italian team has built and shipped L/S-band antennas, diplexers and radomes which comprise part of the four antenna packages. Each antenna system consists of either a VHF/UHF, HF, or L/S-band antenna, diplexer, mounting plate, mounting clamp and antenna cable.

The antenna systems, scheduled for delivery aboard shuttle mission STS-101, will make use of four Russian-provided bulkhead feedthroughs on the Service Module. Astronauts aboard ISS will connect the initial ARISS radio transceivers and associated hardware to the antenna systems.

The ISS 'initial station' ham gear recently passed qualification testing. This initial station setup will support amateur operation on voice and AFSK packet on 2 meters and 70 cm.

The ARRL is also reporting that testing is underway on the German built digitalker speaker-microphone, slated for manifest on a shuttle flight in 2000. The device functions as a digital voice memory beacon, reminiscent of the SAFEX digitalkers experimented with on Mir. ISS crew members will be able to record short messages in the digitalker's memory and the unit will then send the message as a beacon at specific time intervals.

Stay tuned to ANS for further developments.

PANSAT PO-34

Downlink frequency not established.
The satellite is not currently available for uplink transmissions.

PANSAT spread-spectrum digital transponders will be available to amateur radio operators in the near future along with software to utilize this technology. The PO-34 command station is located in Monterey, California.

Dan Sakoda, KD6DRA, PANSAT Project Manager recommends 'The ARRL Spread Spectrum Sourcebook' as a good place to start in understanding the spread-spectrum scheme.

SunSat SO-35

Semi-operational. Modes of operation and uplink/downlink frequencies have yet to be officially established.

SunSat was launched February 23, 1999 aboard a Delta II rocket from Vandenberg Air Force Base in California. SunSat stands for Stellenbosch University Satellite and takes it name from the South African university whose students constructed the payload.

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.

The following satellites are in orbit but are non-operational at this time:

Mir Space Station

Ham radio activity aboard the Mir space station came to a close on August 28, 1999 as the crew returned to Earth, leaving the station unmanned. Mir is in a stable orbit with only essential systems running. All amateur radio activities have ceased. Currently, the station is being prepared for re-entry sometime in the first quarter of 2000. However, the final fate of the space station has not been formally announced. Stay tuned to ANS for further developments.

Current Amateur Radio equipment aboard Mir includes:

SAFEX II 70cm Repeater
Uplink 435.750 MHz FM with subaudible tone 141.3 Hz
Downlink 437.950 MHz FM
