AMSAT's Bruce Paige, KK5DO, reported to ANS that two cosmonauts -- Sergei Zalyotin and Alexandr Kaleri -- have arrived on the Russian Mir space station. Several news agencies (including CNN) also reported the April 4th launch from the Baikonur Cosmodrome and the successful docking with Mir. In addition, CNN reported that this mission is the first privately funded manned mission into space.
KK5DO told ANS (via the ARRL Letter) that this mission marks the first time in about eight months the Mir space station has been occupied. While the strong possibility exists for amateur radio operation, that is not considered to be high on the crew's list of priorities. Their first job is to locate a slow leak in the aging spacecraft.
If amateur activity does take place, it most likely will be on 145.985 MHz FM and could include voice, packet or SSTV. As this edition of ANS was being edited, no amateur radio operation from Mir had been reported.
Stay tuned to ANS for further developments.

NASA officials are reporting that a U.S. component for the International Space Station will be ready to fly later this year if the key Russian Zvezda Service Module is delayed again. The launch of the Zvezda module has been delayed over two years. It is currently scheduled to be launched this July.
"We have asked the team building the U.S. component to step up activities for a launch no earlier than December," NASA spokesman Dwayne Brown said.
Called the Interim Control Module, the $210 million, 30,000-pound U.S. unit for the International Space Station is being built at the Naval Research Laboratory facility near Washington D.C. The module, which will carry 11,000 pounds of fuel, is being designed to keep the two pieces of the international station in orbit if the Russians miss the deadline with the Zvezda unit.
After undergoing hardware testing, the interim module will be readied for shipment to Kennedy Space Center in preparation for the possible December launch. NASA (however) reiterated the agency's position that NASA officials fully expect the Zvezda module to fly in July.
Originally, NASA did not want to build the interim module. But after it became clear in 1997 that the Russians would have trouble meeting their commitment on the station, the project was launched.
If launched in December, the interim module would not be a permanent measure (in that it does not provide living quarters like the Russian Zvezda unit). However, it would keep the station orbiting, awaiting either the Zvezda module at some point or a replacement system. If Zvezda is launched in July, the interim module would be launched anyway, around 2001, to give the station added strength.
No amateur radio operation from the International Space Station is scheduled until permanent human occupation is achieved aboard ISS.
Built by the United States, Russia and 14 other nations, the orbiting International Space Station is intended to be an arena for space-based research that will open new frontiers.

AMSAT-NA will sponsor the 18th Space Symposium and AMSAT-NA Annual Meeting this October. A mainstay of the Symposium has been the annual jewelry contest, overseen by Dave, WB6LLO, and Leanore KA6UCD.
Dave tells ANS that the contest this year is in the form of a brooch that was "carved out of a gold plated circuit board in the shape of a tuna." The board was donated by Qualcomm, delivered by Kerry Banke, K6IZW, during the 1999 Symposium in San Diego, California. The brooch is about three inches long, comes with a safety clasp, and can be pinned on or hung from a suitable chain.
WB6LLO says the original board components have nothing to do with the contest solution. Contestants, (should they choose to take the assignment!) will need to determine the resonant frequency of the parallel tank circuit formed by the 'eye' and the 'mouth' of the tuna. The frequency is in one of the amateur satellite bands. The eye is a miniature variable capacitor - set at 7.0 pF. The mouth is a coil of #24 plated copper wire. It is 6 turns, 0.25 inches in diameter and 0.25 inches long. The wire spacing is one wire diameter. Dave reports the angular separation to form the 'mouth' of the tuna is of some consequence, and should be considered in the answer calculations.
WB6LLO also reports that the eventual winner can re-set the capacitor to his frequency preference!
Leanore, KA6UCD, will be wearing the brooch at the October 2000 Symposium and will announce the winner of the contest at the Symposium banquet. If the winner is present, the broach will be presented to the winner.
Dave tells ANS that anyone can enter. Entry is very simple, just send your guess by e-mail to ka6ucd@amsat.org (or) wb6llo@amsat.org
The answer should be in the following format:
XXX.XXXXXX MHz
Dave says that he has no way he can measure it that accurately, "but the answer is set this way purposely to eliminate ties."
More information about the contest and the broach can be found at http://home.san.rr.com/doguimont/uploads

An AO-27 question-and-answer page is available on the AMSAT-NA web site. http://www.amsat.org/amsat/intro/ao27faq.html
AO-27 uses a method called Timed Eclipse Power Regulation (TEPR) to regulate the on-board batteries. In simple terms, TEPR times how long the satellite has been in the eclipse (or in the sun) and decides what subsystems to turn on or off. The AO-27 pages on the AMSAT-NA web site include an explanation of AO-27 operations at http://www.amsat.org/amsat/sats/n7hpr/ao27.html
Chuck, KM4NZ, recently reset the TEPR states on AO-27 (on March 19).

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 http://sunsat.ee.sun.ac.za/ham1.htm
GPS data is currently collected on Mondays. It takes as much as twelve hours to fully recover the state of charge after these experiments.

Chris Jackson, G7UPN, reports to ANS that UO-22 has now entered full sunlight and the temperatures have increased considerably. Controllers have turned the satellite upside down to point the critical systems to cold space. This has reduced the temperature on various systems (such as the batteries) by between 5 and 10 degrees. The unfortunate by-product of this is that the downlink is now quite weak.
Only the 145.900 MHz receiver is usable for communications at the moment.
More information on the satellite is available at http://www.sstl.co.uk

OSCAR-11 celebrated its sixteenth birthday on March 1, 2000.
During the period of 15-February to 16-March - good signals have been received from the 145 MHz beacon. Battery voltage during daylight passes has been unchanged. The average DC value observed was 13.8 volts, with a range of 13.4 to 14.1 volts. The internal satellite temperatures have decreased by one degree Celsius. They are now 3.8C and 2.2C for battery and telemetry electronics respectively. A single WOD survey of channels 10, 20, 30 and 40 has been transmitted.
The operating schedule is unchanged.

Russ, WJ9F, reports ground stations are currently running memory test software on the satellite. In addition to the memory testing, the spacecraft spin rate around the vertical (Z) axis has created a less than ideal condition for battery charging. The spin rate evaluation confirms a spin rate of 1 revolution every 18 minutes. Power output is low due to this spin rate.
The S-band transmitter is currently off.

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.
