Future Space Station Resident Joins Assembly Crew

Veteran cosmonaut Sergei Krikalev, who will be one of the first full-time residents on board the International Space Station, will join the crew of STS-88, the first American assembly mission. Krikalev will join Commander Robert Cabana, Pilot Rick Sturckow, Mission Specialists Nancy Currie, Jerry Ross and Jim Newman when the Space Shuttle Endeavor launches this December. The seven-day mission will be highlighted by the mating of the United States built 'Unity' module to the Russian built 'Zarya' control module, which will already be in orbit. Zarya, which was built for NASA by Boeing and the Krunichev Enterprise, is scheduled for launch on a Russian Space Agency Proton rocket from the Baikonur Cosmodrome this November.

"Sergei's experience with both the U.S. and Russian programs and his familiarity with the Shuttle make him a valuable addition to this crew," said David Leestma, director of Flight Crew Operations at NASA's Johnson Space Center.

A cosmonaut since 1985, Krikalev has accumulated more than one year and three months in space as a member of two Mir space station crews. He has also flown on board the Shuttle once before, as a member of the STS-60 crew in February 1994. During that nine-day mission, Krikalev operated the Shuttle's robot arm and supported a wide variety of science experiments.

Amateur Radio on the ISS

Amateur Radio delegates representing seven of the eight countries involved in Amateur Radio aboard the International Space Station (ARISS) met in England in late July to continue plans to establish the first permanent Amateur Radio presence in space. The session, chaired by Space Amateur Radio EXperiment (SAREX) Working Group Chairman Roy Neal, K6DUE was held July 29-31 in conjunction with the AMSAT-UK 1998 Colloquium, held at the University of Surrey.

On hand or patched in via a teleconferencing hookup were 16 representatives from the United States, Japan, Italy, Germany, Canada, the United Kingdom and Russia. The representative from France was unable to attend because of a prior commitment.

ARRL Educational Activities Department Manager Rosalie White, WA1STO and AMSAT-NA Vice President for Human Space Flight Programs Frank Bauer, KA3HDO, served as the US delegate for the ARISS meeting. Participants to the sessions included AMSAT-NA President Bill Tynan, W3XO; Space Shuttle Payload Specialist Ron Parise, WA4SIR; and RSGB President Ian Kyle, GI8AYZ. IARU satellite frequency coordinators from Regions 1 and 3 also were on hand.

ARISS delegates formed two permanent working groups. The ARISS Hardware Group, chaired by Lou McFadin, W5DID, is charged with designing and building space station equipment. The ARISS Administrative Group is charged with setting up ground rules for operation, finding financing, and handling all other administrative details.

AMSAT-NA ARISS Delegate Frank Bauer, KA3HDO, said ham radio will be part of the ISS right from the start of construction. "What we're going to do is develop this in stages," he said. The first flight of hardware aboard STS-88 (at the end of this year) will include a 2-meter hand-held and packet TNC capability provided by the US team that will be coupled with an antenna system that will be a cooperative effort of the Italian and Russian teams.

The ISS service module, due to be launched next summer, is the section of the ISS in which astronauts and cosmonauts will live during construction. The interim station for the first ISS crew at that point would add (a US-supplied) 70cm capability, a German-designed "digitalker," and eventually a transportable station that could include SSTV and full-duplex VHF/UHF. The first crews to actually live aboard the ISS will graduate to mobile-type transceivers.

Bauer says the final ISS equipment complement is still in the conceptual stages but likely would include all-mode capability from 10 meters up through 13 cm. He was quite excited about the teamwork exhibited by the international partners, stating that "as an international team, we were able to quickly put together an interim station -- leveraging developments already in progress by Will Marchant, KC6ROL and Lou McFadin, W5DID in the US, Thomas Kieselbach, DL2MDE in Germany and Sergei Samburov, RV3DR in Russia."

Surrey ARISS delegates also discussed time-sharing and scheduling of the ham stations, crew training, educational opportunities, fund-raising, call signs, and frequencies. Details on these issues remain to be decided.

Neal credited SAREX Working Group Principal Investigator Matt Bordelon, KC5BTL, for "a superb job of lining up the NASA/ISS officials and channels for what's about to happen." A key player on the ARISS team, Bordelon is scheduled to travel to Russia soon to work out details of the station installation aboard the ISS service module with Serge Samburov, RV3DR, the Russian delegate.

Neal said he was gratified to see the plans coming together to put Amateur Radio aboard the ISS. "These meetings have gotten the worldwide Amateur Radio family on track," he said. "Amateur Radio is now getting ready to fly onboard!"

White said the most significant aspect of the session came on the afternoon of the second day, which was when countries stepped forward to accept responsibility for various aspects of each Amateur Radio station. "For instance, for the interim Amateur Radio station, the US took responsibility for the packet module, adapter module, radio, and associated cables," she said. White said Germany agreed to build the digitalker and to work with Russia to develop the antenna feed-through system. Italy will design and fabricate the antennas, and Russia will install the RF cables and antennas.

For the transportable setup, the US will handle the equipment integration and the NASA-required Safety Data Package, while Germany will design and build the system itself.

"The ARISS project will truly be an international project," said White. "It will be well worth our years of work, because each delegate believes ARISS is a wonderful resource for the Amateur Radio service and a great educational tool for our world's youth."

Mexico and Russia to Sell Radio Spectrum

On the international scene, ANS has learned that both Russia and Mexico are planning to auction off radio spectrum to the highest bidder, following the lead of the United States.

The Russian government has decided to charge mobile communication companies for the use of radio spectrum as a way to generate some cash for its strapped economy. Two recently released governmental decrees listed the communications services for which providers will have to pay for use of radio frequencies. The decrees also set rules for holding auctions to determine who gets the licenses for cellular telephone systems in Russia.

Under the decrees, 80% of money earned from the sale of spectrum would be used to support the Ministry of Defense and the Russian Space Agency.

The Russian government also indicated that it plans to sell off part of its reserved spectrum for licensed civilian operations. It also said it will review current usage of all other spectrum used for any purpose with an eye at generating even more revenue. This might even include some of the bands now used by Russian hams.

Mexico is also contemplating the reallocation of spectrum adjacent to the 2 meter and 70-centimeter ham bands and then selling the spectrum the highest bidders. It is unknown at this time how such actions would affect Amateur Radio satellite operations.

According to Bob Gonsett's CGC Communicator, Mexico will be auctioning 148-174 MHz and 450-470 MHz, along with other key frequency bands sometime before the end of 1998. The CGC report says it appears as if Mexico is also contemplating to auction off the 440 to 450 MHz Amateur Radio band and the frequency spectrum from 485 to 495 MHz. The latter spectrum overlays TV Channels 16, 17, and 18.

More information on can be found at the following Mexican government web site:

The web site has English and Spanish versions available.

The current crew onboard Mir are Talgat Musabayev and Nikolai Budarin. They speak and read Russian only. Any messages addressed as personal to R0MIR will not be understood unless it is in Russian. MIREX is again allowing R0MIR-1 for store-and-forward message traffic.

WA6LIE reminds all stations that in order to send Personal Mail to other stations you must address it to a valid callsign. Any personal mail addressed to a non-amateur callsign can not be read by anyone and is a waste of TNC memory. WA6LIE asks all stations to please read your TNC manual on how to address messages.

The PBBS is running a Kantronics KPC-9612 + V.8.1 TNC. The commands are similar to most PBBS and BBS systems.

MIREX has announced an on going APRS School Days Test. MIREX is allowing schools to use APRS for position and status reports via R0MIR. Non-school stations are asked to refrain from using APRS type transmissions or beacons via R0MIR.
